    JAX-RS service 404 error: No root resource matching requested path

    Oren Livne Novice

      Dear All,

       

      I am badly stuck on the following issue. I wrote a JAX-RS-annotated web service POJO and deployed it to FUSE ESB 4.1.0.0 using the CXF <jaxrs:server> annotation in the bundle-context.xml file of the bundle. The main CXF services page shows that the service is registered under /fqe. However, when I hit a service method in my browser, jetty reports an HTTP 404 error (URL not found). I tried many different configurations according to forum postings, e.g. deploying the service programmatically in the afterPropertiesSet() method instead of in the XML context file -- commented in the code below, but none work.

       

      I also tried the standard Spring DM weather service example by Roberto Rojas, and this produced exactly the same behavior. Can you please advise on how to correctly implement JAX-RS web services in FUSE ESB?

       

      Thank you in advance.
