Hi,
I'm trying to get jbpm2 ( http://www.jbpm.org/2/ ) work on SunONE7, I find on google for resolving transaction manager problem and I take this as good solution:

http://opensource.atlassian.com/project ... wse/HB-689

but (as write on the bottom of the page) I get an java.lang.IncompatibleClassChangeError exception,

this is a stacktrace:
....
[cut]
....

As you can see, the problem seems to be an hibernate problem

Anyone have a solution for it or I skipped some post??

Tanks for the reply and sorry for my english ;)

Sounds like a classloader issue.
Try to recompile Hibernate with the same JDK running Sun One

Do it, but without changes, I forgot to specify that jbpm2 has hibernate 2.1.1 boundled.

I've rebuilded last version (2.1.4) with the same version of JDK (1.4.2_04) that was used from Sun One, updated the war and the error is the same.

If I try to do what is written on the thread

http://opensource.atlassian.com/project ... wse/HB-689

I got an exception like those in first post during startup of webapp, else if I don't specify the class for transaction manager lookup I got this exception during execution of jbpm process:
