I have the CF9 Beta deployed as a WAR file under Tomcat 6. I was trying to test out the ORM stuff and hit a strange problem. Whenever I tried to call any of the CF ORM functions, the request would suddenly die. Looking at the application server logs I noticed lots of entries like:

java.lang.NoClassDefFoundError: javax/transaction/Synchronization

For some reason I didn’t seem to have jta.jar (required library for Hibernate), so I added it manually to the CF lib directory and everything started working properly.

Wonder if anyone else has had this problem???
