This feature enables support for Java API for RESTful Web Services. JAX-RS annotations can be used to define web service clients and endpoints that comply with the REST architectural style. Endpoints are accessed through a common interface that is based on the HTTP standard methods.
To enable the Java RESTful Services 2.0 feature, add the following element declaration inside the featureManager element in your server.xml file:
<feature>jaxrs-2.0</feature>
If you are developing a feature that depends on the Java RESTful Services 2.0 feature, include the following item in the Subsystem-Content header in the feature manifest file for your new feature:
com.ibm.websphere.appserver.jaxrs-2.0; type="osgi.subsystem.feature"
