Payara Deployment Transformer

The Deployment Transformer extension integrates the Eclipse Jakarta EE namespace transformer into Payara Server, allowing a user to have their Jakarta EE 8 applications transformed on the fly into the Jakarta EE 10 namespace.

You can find the code for the transformer here:

Installing the Extension

To install the transformer extension: download the implementation artifact and drop it into the ${PAYARA_HOME}/glassfish/modules directory of your Payara Server installation. Alternatively, you can build the deployment-transformer/deployment-transformer-impl module straight from the Github repository and drop all JARs from the target/ directory of the extension into the same installation directory.

You can then restart the server to see your extension activated.

The 'deployment-transformer-api' artifact is already included with Payara Server and so you only need to provide an implementation

Activating the Transformer Extension

The transformer, once installed, is activated in one of two ways:

  • Setting the fish.payara.deployment.transform.namespace system property on a server config or instance to true

  • Having fish.payara.deployment.transform.namespace unconfigured, and deploying an application which doesn’t contain any jakarta.* classes.
