Hi Daniel,
I don't have an answer yet for your issue, but I'm collecting info to try figuring out what's happening.
So, first of all the WARNING JBWS024027 basically means that an initial attempt of creating the a spring application context failed, so another try is being done with a different thread context classloader; so my first question is, do you get any other exception/log about error besides the the JBWS024027 above? If not, that would mean the following creation of the application context succeeds. In any case it will help in nailing down the problem...
