Hi,
I believe this is from another classloder issue, that said, the
classloader(it could be your servlet war classloader) which load
org.apache.cxf.transport.servlet.CXFServlet isn't the one(it could be
the container classloader) which load javax.servlet.Servlet, so
although org.apache.cxf.transport.servlet.CXFServlet is actually a
servlet class, you still see such exception.
This should come from the class loader policy you changed here. The
workaround probably could be you add a jar(like geronimo-
servlet_3.0_spec.jar) which contain javax.servlet.Servlet in your WEB-
INF/lib.
I'd say this kind of lib version conflict issue(neethi in your case)
between the container and your application module(the war) is really
general, the self-first classloader solution may not always work and
it may bring more troubles, the root reason is that the classloader
mechanism used by JEE/Servlet container isn't very dynamic and you
actually have no full control about how to load classes from your own
module, to fix this kind of issue, a new technique(OSGi container) was
brought up and it is very powerful to handle such problem you
encounter, you can easily specify the lib version you want to use in
your own module, and different versions lib co-exist in same container
won't be a problem anymore.
