    Rest Server returns HTTP 405 Error

      Hello all and thanks for reading my post.

       

      This issue isn’t related to an Infinispan Cache issue; however I’m trying to get my client communicating with the Rest server so I can start working on implementing the Infinispan Cache.  I found this link:  http://www.theserverside.com/tip/RESTful-Web-services-made-easy.  When I try to invoke a simple service using the example code, I get “HTTP Status 405 - specified HTTP method is not allowed for the requested resource ()”.  The web.xml in the example shows a servlet mapping to a Jersey ServletContainer.  I’m not using Jersey; is there a different ServletContainer I should use instead?  If I do, will this conflict with the HttpServletDispatcher?
