Thanks for your reply nille hammer, but your solution did not solve my problem-> same exception, same message.
I found a solution by myself, but i did not really understand it: When i exclude the library tapestry-hibernate-5.0.11.jar out of the build path my and your code works fine. Is this because T5 ist still beta or ist the problem on my site? Has somebody an explanation for that?
