A bundle project producing JAX-RS RI bundles. The primary artifact is an "all-in-one" OSGi-fied JAX-RS RI bundle (jaxrs-ri.jar). Attached to that are two compressed JAX-RS RI archives. The first archive (jaxrs-ri.zip) consists of binary RI bits and contains the API jar (under "api" directory), RI libraries (under "lib" directory) as well as all external RI dependencies (under "ext" directory). The secondary archive (jaxrs-ri-src.zip) contains buildable JAX-RS RI source bundle and contains the API jar (under "api" directory), RI sources (under "src" directory) as well as all external RI dependencies (under "ext" directory). The second archive also contains "build.xml" ANT script that builds the RI sources. To build the JAX-RS RI simply unzip the archive, cd to the created jaxrs-ri directory and invoke "ant" from the command line.

There is a newer version: 3.1.6

/**
 * A resource method dispatcher provider factory.
 * 
 * This class is used by {@link org.glassfish.jersey.server.model.ResourceMethodInvoker} to
 * create a {@link org.glassfish.jersey.server.spi.internal.ResourceMethodDispatcher.Provider} instance
 * that will be used to provide a {@link org.glassfish.jersey.server.spi.internal.ResourceMethodDispatcher}
 * instances for all resource method invocations.
 * 
 * 
 * JAX-RS resource methods are invoked by {@link org.glassfish.jersey.server.model.ResourceMethodInvoker
 * resource method invoker}. Whenever a new incoming request has been routed to a resource method and the
 * method is being invoked by the resource method invoker, the invoker consults a registered
 * {@link org.glassfish.jersey.server.spi.internal.ResourceMethodDispatcher.Provider} instance to retrieve
 * a {@link org.glassfish.jersey.server.spi.internal.ResourceMethodDispatcher} that will be ultimately used
 * to dispatch the resource method invocation. This mechanism is useful for implementing any resource method
 * interception logic.
