I am using CXF 2.3.1. My development platform is Windows XP and IBM version of
Java 5.0 (IBM J9 VM (build 2.3, J2RE 1.5.0 IBM J9 2.3 Windows XP x86-32
j9vmwi3223ifx-20100125 (JIT enabled)). I am using Websphere Application Server
6.1.0.31. When I deploy the application, it deploys successfully. But, when I
try to access the service I get the following message in the application server
logs.
the exception is
java.lang.ClassCastException: org.apache.cxf.transport.servlet.CXFServlet
incompatible with javax.servlet.Servlet
