Using REST Interfaces to Administer Payara Server

Payara Server provides representational state transfer (REST) interfaces to enable you to access monitoring and configuration data for Payara Server, including data that is provided by newly installed add-on components.

You can access the Payara Server REST interfaces through client applications such as:

  • Web browsers

  • REST API Clients

  • cURL

It allows execution of administration commands in a similar way as the asadmin utility, such as:

  • Execute administration commands to modify the domain’s configuration.

  • Retrieve monitoring statistics

  • Look at the domain’s log entries.

Using REST URLs to Administer Payara Server

Each object in the configuration and monitoring object trees is represented as a REST resource that is accessible through an HTTP uniform resource locator (URL).

Access to REST resources for Payara Server monitoring and configuration data requires a running DAS.

REST URLs to Resources for Configuration and Monitoring Objects

The formats of the URLs to resources that represent objects in the configuration and monitoring object trees are as follows:

The replaceable items in these URLs are as follows:

host

The host where the DAS is running.

port

The HTTP port or HTTPS port for administration.

path

The path to the object. The path is the dotted name of the object in which each dot (.) is replaced with a slash (/).

The path to a Payara Server instance is servers/server/<instance-name>, where instance-name is the name of the instance. For the DAS, instance-name is server and the path is servers/server/server.

If the URL to a REST resource for Payara Server monitoring or configuration data is opened in a web browser, the browser displays a web page that contains the following information about the resource:

  • A list of the attributes of the resource and their values. If the resource represents an object in the configuration tree, these attributes are presented in an HTML form that you can use to update the resource. Attributes of a resource for an object in the monitoring tree are read only.

  • A list of hypertext links to the children of the resource. This list of links enables you to traverse the tree that contains the resource and to discover the all resources in the tree.

  • A list of hypertext links to resources that represent asadmin subcommands for non-CRUD operations on the resource.

The following figure shows the web page for the REST resource for managing a domain.

Web Page for the REST Resource for Managing a Domain

REST resource for managing a domain.

REST URLs for Accessing the Log File

The server.log file of the DAS is represented as a child that is named view-log of the resource for managing the domain. A child of the resource for the server.log file represents the log file details

The formats of the URLs to resources that represent the log file are as follows:

The replaceable items in these URLs are as follows:

host

The host where the DAS is running.

port

The HTTP port or HTTPS port for administration.

You can use the optional start parameter in the URL to the resource for the log file to specify the number of characters at the start of the file to skip.

For example, to skip 10,000 characters, specify the URL as http://localhost:4848/management/domain/view-log?start=10000. This example assumes that the DAS is running on the local host and uses the default port for administration.

The resource for the log file returns the HTTP header X-Text-Append-Next, which contains the entire URL to pass to the GET method to return the changes since the last call. You can use this header in client applications to get all log entries that were added in particular interval.

For example, by testing the value of the X-Text-Append-Next header in a client thread every 10 seconds, you can monitor the log entries that were added in the last 10 seconds.

Using REST Resource Methods to Administer Payara Server

The Payara Server REST interfaces support methods for accessing objects in the monitoring and configuration object trees.

The following table shows the REST methods for administering monitoring and configuration data and the tasks that you can perform with each method.

Table 1. REST Resource Methods for Administering Monitoring and Configuration Data

Task

REST Method

Determine the methods and method parameters that an object in the tree supports

GET

Retrieve data for an object in the tree

GET

Add an object to the tree

POST

Update an object in the tree

POST

Delete an object from the tree

DELETE

REST requests that add, update, or delete objects must specify the X-Requested-By header with the value GlassFish REST HTML interface.

The GET method determines the methods and method parameters that an object in the tree supports and provides additional information about the object. For details, see To Retrieve Data for an Object in the Tree.

To Determine the Methods and Method Parameters That an Object in the Tree Supports

The methods and method parameters that an object in the tree supports depend on the REST resource that represents the object:

  • REST resources for monitoring support only the GET method.

  • All REST resources for configuration support the GET method.

    However, only some REST resources for configuration also support the POST method and the DELETE method.

Before performing any operations on an object in the tree, determine the methods and method parameters that the object supports.

You can specify the format in which this information is presented. For more information, see Formats for Resource Representation of Configuration Objects.

Each POST method and DELETE method that a REST resource supports has an equivalent asadmin subcommand. The parameters of a POST method or a DELETE method correspond to the options of the method’s equivalent asadmin subcommand.
  1. Ensure that the server is running. Operations on REST resources for Payara Server data require a running server.

  2. Use the GET method on the REST resource that represents the object. The GET method returns the list of methods that the resource supports. For each method, the list of acceptable message parameters or the list of acceptable query parameters are returned.

This example uses the cURL utility to determine the methods and method parameters that the resource for the node sj01 supports.

The example uses the following options of the cURL utility:

  • -X to specify that the GET method is used

  • -H to specify that the resource is represented in JavaScript Object Notation (JSON)

In this example, the DAS is running on the local host and the HTTP port for administration is 4848. The resource supports the GET method and the POST method.

curl -X GET -H "Accept: application/json" http://localhost:4848/management/domain/nodes/node/sj01

{
  "command":"Node",
  "exit_code":"SUCCESS",
  "extraProperties":{
    "commands":[
      {"path":"_delete-node","command":"delete-node","method":"DELETE"},
      {"path":"_update-node","command":"_update-node","method":"POST"},
      {"path":"ping-node-ssh","command":"ping-node-ssh","method":"GET"},
      {"path":"update-node-ssh","command":"update-node-ssh","method":"POST"},
      {"path":"update-node-config","command":"update-node-config","method":"POST"}],
    "methods":[
      {"name":"GET"},
      {"name":"POST","messageParameters":{
        "installDir":{"optional":"true","type":"string","key":"false"},
        "nodeDir":{"optional":"true","type":"string","key":"false"},
        "nodeHost":{"optional":"true","type":"string","key":"false"},
        "type":{"optional":"true","type":"string","key":"false"}
        }
      }
    ],
    "entity":{
      "installDir":"\/export\/payara6",
      "name":"sj01",
      "nodeDir":null,
      "nodeHost":
      "sj01.example.com",
      "type":"SSH"
    },
    "childResources":{
      "application-ref":
        "https:\/\/localhost:4848\/management\/domain\/nodes\/node\/sj01\/application-ref",
      "resource-ref":
        "https:\/\/localhost:4848\/management\/domain\/nodes\/node\/sj01\/resource-ref",
      "ssh-connector":
        "https:\/\/localhost:4848\/management\/domain\/nodes\/node\/sj01\/ssh-connector"
    }
  }
}

To Retrieve Data for an Object in the Tree

Retrieving data for an object in the tree obtains the following information about the REST resource that represents the object:

  • A list of the REST methods that the resource supports

  • A list of the attributes of the resource and their values

  • A list of URLs to the children of the resource

You can specify the format in which this information is presented. For more information, see Formats for Resource Representation of Configuration Objects.

  1. Ensure that the server is running. Operations on REST resources for Payara Server data require a running server.

  2. Use the GET method on the REST resource that represents the object.

This example uses the cURL utility to retrieve data for the resource for a the node sj01. The example uses the following options of the cURL utility:

  • -X to specify that the GET method is used

  • -H to specify that the resource is represented in JavaScript Object Notation (JSON)

In this example, the DAS is running on the local host and the HTTP port for administration is 4848.

curl -X GET -H "Accept: application/json" http://localhost:4848/management/domain/nodes/node/sj01
{
  "command":"Node",
  "exit_code":"SUCCESS",
  "extraProperties":{
    "commands":[
      {"path":"_delete-node","command":"delete-node","method":"DELETE"},
      {"path":"_update-node","command":"_update-node","method":"POST"},
      {"path":"ping-node-ssh","command":"ping-node-ssh","method":"GET"},
      {"path":"update-node-ssh","command":"update-node-ssh","method":"POST"},
      {"path":"update-node-config","command":"update-node-config","method":"POST"}],
    "methods":[
      {"name":"GET"},
      {"name":"POST","messageParameters":{
        "installDir":{"optional":"true","type":"string","key":"false"},
        "nodeDir":{"optional":"true","type":"string","key":"false"},
        "nodeHost":{"optional":"true","type":"string","key":"false"},
        "type":{"optional":"true","type":"string","key":"false"}
        }
      }
    ],
    "entity":{
      "installDir":"\/export\/payara6",
      "name":"sj01",
      "nodeDir":null,
      "nodeHost":
      "sj01.example.com",
      "type":"SSH"
    },
    "childResources":{
      "application-ref":
        "https:\/\/localhost:4848\/management\/domain\/nodes\/node\/sj01\/application-ref",
      "resource-ref":
        "https:\/\/localhost:4848\/management\/domain\/nodes\/node\/sj01\/resource-ref",
      "ssh-connector":
        "https:\/\/localhost:4848\/management\/domain\/nodes\/node\/sj01\/ssh-connector"
    }
  }
}

To Add an Object to the Tree

  1. Ensure that the server is running. Operations on REST resources for Payara Server data require a running server.

  2. Determine the acceptable message parameters for the POST method of the resource that represents the parent of the object. For information about how to perform this step, see To Determine the Methods and Method Parameters That an Object in the Tree Supports.

  3. Use the POST method on the REST resource that represents the parent of the object that you are adding.

  4. Confirm that the object has been added. Perform this step on the resource that represents the object that you have just added, not the parent.

    For information about how to perform this step, see To Retrieve Data for an Object in the Tree.

This example uses the cURL utility to add a JDBC resource object to the tree by creating a REST resource to represent the JDBC resource.

In this example, the DAS is running on the local host and the HTTP port for administration is 4848.

  1. This step determines the acceptable message parameters for the POST method of the resource jdbc-resource.

    curl -X GET -H "Accept: application/json"
    
    http://localhost:4848/management/domain/resources/jdbc-resource
    {
      "command":"Jdbc-resource",
      "exit_code":"SUCCESS",
      "extraProperties":{
        "commands":[],
        "methods":[
          {"name":"GET"},
          {"name":"POST","messageParameters":{
            "description":{"acceptableValues":"","optional":"true","type":"string","defaultValue":""},
            "enabled":{"acceptableValues":"",optional":"true","type":"boolean",defaultValue":"true"},
            "id":{"acceptableValues":"","optional":"false","type":"string","defaultValue":""},
            "poolName":{"acceptableValues":"","optional":"false","type":"string","defaultValue":""},
            "property":{"acceptableValues":"","optional":"true","type":"string","defaultValue":"},
            "target":{"acceptableValues":"","optional":"true","type":"string","defaultValue":""}
            }
          }
        ],
        "childResources":{
          "jdbc\/__TimerPool":
            "https:\/\/localhost:4848\/management\/domain\/resources\/jdbc-resource\/jdbc%2F__TimerPool",
          "jdbc\/__default":
            "https:\/\/localhost:4848\/management\/domain\/resources\/jdbc-resource\/jdbc%2F__default"
        }
      }
    }
  2. This step adds a resource as a child of the jdbc-resource resource. The -d option of the cURL utility sets the required message parameters as follows:

    • id is set to jdbc/myjdbcresource.

    • connectionpoolid is set to DerbyPool.

      curl -X POST -H "X-Requested-By: GlassFish REST HTML interface" -d id=jdbc/myjdbcresource -d connectionpoolid=DerbyPool
      http://localhost:4848/management/domain/resources/jdbc-resource
  3. This step confirms that the object has been added by retrieving data for the REST resource that represents the object.

    curl -X GET -H "Accept: application/json"
    http://localhost:4848/management/domain/resources/
    jdbc-resource/jdbc%2Fmyjdbcresource
    {
      "command":"Jdbc-resource",
      "exit_code":"SUCCESS",
      "extraProperties":{
        "commands":[],
        "methods":[
          {"name":"GET"},
          {"name":"POST","messageParameters":{
            "description":{"optional":"true","type":"string","key":"false"},
            "enabled":{"optional":"true","type":"boolean","defaultValue":"true","key":"false"},
            "jndiName":{"optional":"true","type":"string","key":"true"},
            "objectType":{"optional":"true","type":"string","defaultValue":"user","key":"false"},
            "poolName":{"optional":"true","type":"string","key":"false"}
            }
          },
          {"name":"DELETE","messageParameters":{
            "target":{"acceptableValues":"","optional":"true","type":"string","defaultValue":""}
            }
          }
        ],
        "childResources":{
          "property":
            "https:\/\/localhost:4848\/management\/domain\/resources\/jdbc-resource\/jdbc%2Fmyjdbcresource\/property"
        }
      }
    }

To Update an Object in the Tree

  1. Ensure that the server is running.

    Operations on REST resources for Payara Server data require a running server.

  2. Determine the acceptable message parameters for the POST method of the resource that represents the object. For information about how to perform this step, see To Determine the Methods and Method Parameters That an Object in the Tree Supports.

  3. Use the POST method on the REST resource that represents the object that you are updating.

  4. Confirm that the object has been updated. For information about how to perform this step, see To Retrieve Data for an Object in the Tree.

This example uses the cURL utility to update a JDBC resource in the tree by modifying the REST resource that represents the JDBC resource.

In this example, the DAS is running on the local host and the HTTP port for administration is 4848.

  1. This step determines the acceptable message parameters for the POST method of the resource jdbc-myjdbcresource.

    curl -X OPTIONS -H "Accept: application/json" http://localhost:4848/management/domain/resources/jdbc-resource/jdbc-myjdbcresource
    
    {
      "command":"Jdbc-resource",
      "exit_code":"SUCCESS",
      "extraProperties":{
        "commands":[],
        "methods":[
          {"name":"GET"},
          {"name":"POST","messageParameters":{
            "description":{"optional":"true","type":"string","key":"false"},
            "enabled":{"optional":"true","type":"boolean","defaultValue":"true","key":"false"},
            "jndiName":{"optional":"true","type":"string","key":"true"},
            "objectType":{"optional":"true","type":"string","defaultValue":"user","key":"false"},
            "poolName":{"optional":"true","type":"string","key":"false"}
            }
          },
          {"name":"DELETE","messageParameters":{
            "target":{"acceptableValues":"","optional":"true","type":"string","defaultValue":""}
            }
          }
        ],
        "childResources":{
          "property":
            "https:\/\/localhost:4848\/management\/domain\/resources\/jdbc-resource\/jdbc%2Fmyjdbcresource\/property"
        }
      }
    }
  2. This step updates the REST resource jdbc-myjdbcresource to disable the JDBC resource that jdbc-myjdbcresource represents.

The -d option of the cURL utility sets the enabled message parameter to disabled.

+

curl -X POST -H "X-Requested-By: GlassFish REST HTML interface" -d "enabled=false" http://localhost:4848/management/domain/resources/jdbc-resource/jdbc%2Fmyjdbcresource
  1. This step confirms that the object has been updated by retrieving data for the REST resource that represents the object.

    curl -X GET -H "Accept: application/json"
    http://localhost:4848/management/domain/resources/
    jdbc-resource/jdbc%2Fmyjdbcresource
    {
      "command":"Jdbc-resource",
      "exit_code":"SUCCESS",
      "extraProperties":{
        "commands":[],
        "methods":[
          {"name":"GET"},
          {"name":"POST","messageParameters":{
            "description":{"optional":"true","type":"string","key":"false"},

            "user","key":"false"},
            "poolName":{"optional":"true","type":"string","key":"false"}
            }
          },
          {"name":"DELETE","messageParameters":{
            "target":{"acceptableValues":"","optional":"true","type":"string","defaultValue":""}
            }
          }
        ],
      "entity":{
        "description":null,
        "enabled":"false",
        "jndiName":"jdbc\/myjdbcresource",
        "objectType":
        "user",
        "poolName":"DerbyPool"
      },
      "childResources":{
        "property":
          "https:\/\/localhost:4848\/management\/domain\/resources\/jdbc-resource\/
           jdbc%2Fmyjdbcresource\/property"
        }
      }
    }

To Delete an Object From the Tree

  1. Ensure that the server is running. Operations on REST resources for Payara Server data require a running server.

  2. Confirm that the object can be deleted. For information about how to perform this step, see To Determine the Methods and Method Parameters That an Object in the Tree Supports.

  3. Confirm that the object has been deleted. Perform this step on the resource that represents the parent of the object that you have just deleted.

For information about how to perform this step, see To Retrieve Data for an Object in the Tree.

This example uses the cURL utility to delete a JDBC resource from the tree by deleting the REST resource that represents the JDBC resource.

In this example, the DAS is running on the local host and the HTTP port for administration is 4848.

  1. This step confirms that the object can be deleted by retrieving the REST methods that the resource jdbc-myjdbcresource supports.

    Line breaks and white space are added to enhance readability.
    curl -X GET -H "Accept: application/json" http://localhost:4848/management/domain/resources/jdbc-resource/jdbc%2Fmyjdbcresource
    
    {
      "command":"Jdbc-resource",
      "exit_code":"SUCCESS",
      "extraProperties":{
        "commands":[],
        "methods":[
          {"name":"GET"},
          {"name":"POST","messageParameters":{
            "description":{"optional":"true","type":"string","key":"false"},
            "enabled":{"optional":"true","type":"boolean","defaultValue":"true","key":"false"},
            "jndiName":{"optional":"true","type":"string","key":"true"},
            "objectType":{"optional":"true","type":"string","defaultValue":"user","key":"false"},
            "poolName":{"optional":"true","type":"string","key":"false"}
            }
          },
          {"name":"DELETE","messageParameters":{
            "target":{"acceptableValues":"","optional":"true","type":"string","defaultValue":""}
            }
          }
        ],
        "childResources":{
          "property":
            "https:\/\/localhost:4848\/management\/domain\/resources\/jdbc-resource\/
            jdbc%2Fmyjdbcresource\/property"
        }
      }
    }
  2. This step deletes the jdbc/myjdbcresource resource.

    curl -X DELETE -H "X-Requested-By: GlassFish REST HTML interface" http://localhost:4848/management/domain/resources/jdbc-resource/jdbc%2Fmyjdbcresource
  3. This step confirms that the object has been deleted by retrieving data for the REST resource that represents the parent of the object.

    curl -X GET -H "Accept: application/json" http://localhost:4848/management/domain/resources/jdbc-resource
    
    {
      "command":"Jdbc-resource",
      "exit_code":"SUCCESS",
      "extraProperties":{
        "commands":[],
        "methods":[

            "target":{"acceptableValues":"","optional":"true","type":"string","defaultValue":""}
            }
          }
        ],
        "childResources":{
          "jdbc\/__TimerPool":
            "https:\/\/localhost:4848\/management\/domain\/resources\/jdbc-resource\/jdbc%2F__TimerPool",
          "jdbc\/__default":
            "https:\/\/localhost:4848\/management\/domain\/resources\/jdbc-resource\/jdbc%2F__default"
        }
      }
    }

Resources for asadmin Subcommands That Perform Non-CRUD Operations

The Payara Server REST interfaces also support operations other than create, read, update, and delete (CRUD) operations, for example:

  • State Management

  • Queries

  • Application deployment

These operations are supported through REST resources that represent the asadmin subcommands for performing these operations. Each resource is a child of the resource on which the operation is performed. The child resources do not represent objects in the configuration object tree.

For example, the resource that represents a node provides child resources for the following asadmin subcommands that perform non-CRUD operations on the node:

  • ping-node-ssh

  • update-node-config

  • update-node-ssh

Securing Payara Server REST Interfaces

The Payara Server REST interfaces support the following authentication schemes for securing the REST interfaces:

  • Basic authentication over a secure connection

  • Authentication by using session tokens

When security is enabled, you must specify HTTPS as the protocol in the URLs to REST resources and provide a username and password.

Setting Up Basic Authentication Over a Secure Connection

Setting up basic authentication over a secure connection to secure Payara Server REST interfaces involves the following sequence of tasks:

  1. Adding an admin-realm user to the asadmin user group

  2. Enabling Secure Sockets Layer (SSL)

For information about how to perform these tasks from the command line, see the following documentation:

For information about how to perform these tasks by using the Administration Console, see the following topics in the Administration Console online help:

  • To Add a User to the Admin Realm

  • To Edit SSL Settings for a Protocol

To Secure REST Interfaces by Using Session Tokens

Basic authentication requires a REST client to cache a user’s credentials to enable the client to pass the credentials with each request. If you require a REST client not to cache credentials, your client must use session tokens for authentication.

  1. Request a session token by using the GET method on the resource at http://host:port/management/sessions.

    Payara Server uses basic authentication to authenticate the client, generates a session token, and passes the token to the client.

  2. In each subsequent request that requires authentication, use the token to authenticate the client.

  3. Create a cookie that is named gfresttoken the value of which is the token.

  4. Send the cookie with the request.

  5. When the token is no longer required, retire the token by using the DELETE method on the resource at http://host:port/management/sessions/{tokenvalue}.

If a client does not explicitly retire a token, the token is retired after 30 minutes of inactivity.

Formats for Resource Representation of Configuration Objects

The Payara Server REST interfaces represent resources for configuration objects in the following formats:

  • JSON

  • XML

  • HTML

Payara Server enables you to specify the resource representation through the filename extension in the URL or through the HTTP header:

  • To specify the resource representation through the filename extension in the URL, specify the appropriate extension as follows:

    • For JSON, specify the .json extension.

    • For XML, specify the .xml extension.

    • For HTML, omit the extension.

  • How to specify the resource representation through the HTTP header depends on the client that you are using to access the resource. For example, if you are using the cURL utility, specify the resource representation through the -H option as follows:

    • For JSON, specify -H "Accept: application/json".

    • For XML, specify -H "Accept: application/xml".

HTML Resource Representation for Monitoring Objects

The format for the HTML representation of a resource for a monitoring object is a web page that provides the following information about the resource:

  • A list of the statistics that the resource provides.

  • A list of hypertext links to the children of the resource.

The following figure shows the web page for the REST resource that provides class loader statistics for the virtual machine for the Java platform.

Formats for Resource Representation of Log File Details

The Payara Server REST interfaces represent resources for log file details in the following formats:

  • JSON

  • XML

JSON Resource Representation for Log File Details

The general format for the JSON representation of a resource for log file details is as follows:

{
  "records": [
  ]
}

The replaceable item in this format is a record list array, which is one or more metadata sets separated by a comma (,) that represent the log records in the log file. For the format of each metadata set, see JSON Representation of a Log Record in a Record List.

JSON Representation of a Log Record in a Record List

The JSON representation of a log record in a record list is as follows:

{
  "recordNumber":"record-number",
  "loggedDateTimeInMS":"logged-date",
  "loggedLevel":"log-level",
  "productName":"product-name",
  "loggerName":"logger-class-name",
  "nameValuePairs":"_ThreadID=thread-id;_ThreadName=thread-name;",
  "messageID":"message-id",
  "Message":"message-text"
}

The replaceable items in this format are as follows:

record-number

A serial number in the form of a decimal integer that uniquely identifies the log record.

logged-date

The date and time in UNIX time that the record was created.

log-level

The severity level of the message in the log record. For more information, see Setting Log Levels.

product-name

The current name and version of the server runtime.

logger-class-name

The fully qualified name of the Java class of the logger class that created the log message. Each component of Payara Server provides its own logger class.

For detailed information about the names of logger classes in the Payara Server, see Logger Namespaces.

thread-id

The numerical identifier of the thread that created the message.

thread-name

The name of the thread that created the message.

message-id

A unique identifier for the message. For messages from Payara Server, this identifier consists of a module code and a numerical value, for example, CORE5004. All SEVERE and WARNING messages and some INFO messages from Payara Server contain a message identifier.

message-text

The text of the log message.

Example JSON Resource Representation for Log File Details

This example shows the JSON representation of the resource for log file details. In this example, the DAS is running on the local host and the HTTP port for administration is 4848. The URL to the resource in this example is http://localhost:4848/management/domain/view-log/details.

{
  "records": [
    {
      "recordNumber":475,
      "loggedDateTimeInMS":1300743782815,
      "loggedLevel":"INFO",
      "productName":"Payara Server 6.2024.11",
      "loggerName":"org.glassfish.admingui",
      "nameValuePairs": "_ThreadID=25;_ThreadName=Thread-1;",
      "messageID":"",
      "Message":"Admin Console: Initializing Session Attributes..."
    },
    {
      "recordNumber":474,
      "loggedDateTimeInMS":1300728893368,
      "loggedLevel":"INFO",
      "productName":"Payara 6.2024.11",
      "loggerName":"java.enterprise.system.core.com.sun.enterprise.v3.admin.adapter",
      "nameValuePairs":"_ThreadID=238;_ThreadName=Thread-1;",
      "messageID":"",
      "Message":"The Admin Console application is loaded."
    },
    {
      "recordNumber":473,
      "loggedDateTimeInMS":1300728893367,
      "loggedLevel":"INFO",
      "productName":"Payara 6.2024.11",
      "loggerName":"jakarta.enterprise.system.core.com.sun.enterprise.v3.server",
      "nameValuePairs":"_ThreadID=238;_ThreadName=Thread-1;",
      "messageID":"CORE10010",
      "Message":"Loading application __admingui done in 40,063 ms"
    }
  ]
}

XML Resource Representation for Log File Details

The general format for the XML representation of a resource for log file details is as follows:

<records>
 records
</records>

The replaceable item in this format is the records, which is one or more XML elements that represent the log records in the log file. For the format of each element, see XML Representation of a Log Record.

XML Representation of a Log Record

The XML representation of a log record is as follows:

<record loggedDateTimeInMS="logged-date" loggedLevel="log-level" loggerName="logger-class-name" messageID="message-id" nameValuePairs="_ThreadID=thread-id;_thread-name;" productName="product-name" recordNumber="record-number"/>

The replaceable items in this format are as follows:

logged-date

The date and time in UNIX time that the record was created.

log-level

The severity level of the message in the log record. For more information, see Setting Log Levels.

logger-class-name

The fully qualified name of the Java class of the logger class that created the log message. Each component of Payara Server provides its own logger class.

For detailed information about the names of logger classes in Payara Server, see Logger Namespaces.

Supported Content Types in Requests to REST Resources

The Payara Server REST interfaces support the following types in the content-type header of a client request:

How to specify the type in the content-type header depends on how you are sending the request. For example, if you are using the cURL utility, specify the type through the -H option as follows:

  • For JSON, specify -H "Content-type: application/json".

  • For XML, specify -H "Content-type: application/xml".

  • For form URL encoded, specify -H "Content-type: application/x-www-form-urlencoded".
