LinkageError whilst trying to invoke CXF/SOAP webservice

I have a project (say myproject) in which I have hosted a CXF RESTful service and CXF WS/SOAP service, and running on JBoss (6.0.0.FINAL). The RESTful interface is used by all of our internal systems, and the SOAP interface is used by the third party systems (as a callback interface)

Following URLs are working fine.

  • REST URL: http://localhost:8080/myproject/internal/someOperation (content-type: application/json and POST body)

  • SOAP WSDL: http://localhost:8080/myproject/cbsoap?wsdl

Now my problem is that actual SOAP calls are not successful. I use SOAPUI to try the SOAP calls but just to able to query the WSDL. I am getting the following error:-

javax.servlet.ServletException: Servlet execution threw an exception
    org.jboss.weld.servlet.ConversationPropagationFilter.doFilter(ConversationPropagationFilter.java:67)

Solution

  • I finally solved the problem but it is really weird.

    1. I added cxf-rt-frontend-jaxws and cxf-bundle-rs as dependencies and mark some exclusions -> jetty-server, gernomino-servlet.
    2. I had the beans.xml under WEB-INF folder but had to place it under src/main/resources. The beans.xml is expected to be under the classpath, instead of WEB-INF.

    Thanks for your responses.
