            [CAM-5643] Investigate Webapp Problems on WebLogic12R2

            I was able to pin it down to classloading, trying a solution right now.

            I found the cause of the error regarding the REST API. I assume the WebApp suffers from the same issue.

            Situation:
            WebLogic 12R2 is shipping Jersey 2 and Jackson 2.4.3.
            Also since version 2, Jersey is shipping Moxy as the default JSON processor.

            Solution:
            I wrote an weblogic.xml, which makes our Jackson classes available to the correct classloader. I also edited the web.xml to disable Moxy as default JSON processor for Jersey, so it uses our Jackson instead.

            What is the difference to the setup in our test suite? Is moxy not included in the Jersey2 dependency we use there?

            Yes, we just include Jackson like for all others, not Moxy. Maybe we could reproduce it when declaring the Moxy dependency for Jersey. Will try that too.

            Using Moxy dependency together with Jersey breaks alot of things in the testsuite. For example the testsuite was unable to correctly serialize incoming requests to objects.
            Conclusion: We need to make sure that when Jersey or any other JAX-RS provider uses Moxy, only Jackson is used for JSON processing.
