How to deploy JAX-RS Application in WAS 7.0.23?

Question

I am using RAD and WAS 7.0.23, and try to deploy jax-rs in it. But I am getting below error in deployment descriptor(Web.xml).

Error 404: javax.servlet.UnavailableException: SRVE0200E: Servlet [com.ibm.websphere.jaxrs.server.IBMRestServlet]: Could not find required class - class java.lang.ClassNotFoundException: com.ibm.websphere.jaxrs.server.IBMRestServlet

Answer 1

JAX-RS wasn't added to WAS until 8.0. If you want to use JAX-RS on that old a server (which I generally wouldn't recommend for the reason Andy mentioned above), you'll need to bring your own provider.

Answer 2

First, I agree that continuing to use the well-out-of-support 7.0 is unwise.

That said, it may just be that you need to add the jar to the RAD project's "Deployment Assembly", in addition to the "Java Build Path".
