I am working on a J2EE web project using Hibernate. I have configured the project using the MyEclipse J2EE 1.4 library. When I deploy the project to Tomcat 5.5 using MyEclipse and launch the app. I get the following error:
javax.servlet.ServletException: Servlet execution threw an exception

root cause

java.lang.NoClassDefFoundError: javax/transaction/Synchronization
org.hibernate.impl.SessionImpl.<init>(SessionImpl.java:213)
org.hibernate.impl.SessionFactoryImpl.openSession(SessionFactoryImpl.java:473)

javax.servlet.http.HttpServlet.service(HttpServlet.java:810)

If I manually add the MyEclipse J2EE 1.4 Jars to the Tomcat path in the Tomcat 5.5 configuration the problem goes away. However I was under the impression that this was not required. Any ideas?

Cheers,

BTW I’m using MyEclipse 5.5.1 GA

Hi Ashley,
Seems like you are missing the jta.jar. You can go through this thread on how to deal with this error.
