Thanks a lot guys! I finally got it working! The strange thing is that I thought I did exactly this and it didn't help but now I saw that I forgot to remove trinidad-api.jar from WEB-INF/lib and this was causing trouble. Still I find it a bit strange that this is a class loader issue and there were absolutely no exceptions... anyway, happy to get it working.
