I think this is good enough for the initial implementation. Making CXF bundle a fragment of the Tomcat bundle is not a good enough solution to this problem. There is a fundamental class loading issue here specially when it comes to us Spring in OSGI. We need to properly fix this. As we discussed earlier, lets try the option of extending the CXFServlet and setting the classloader of the Spring context as the classloder of the CXF bundle.
