Help~~A Tomcat war package can't be accessed in DM Server

Guys, my web app can be deployed successfully in Tomcat and in DM Server too. But in DM Server (2.0), I can't access to the main page with some struts exceptions (it was developed with springMVC+Struts2+Hibernate ,and was all ok in Tomcat 6) .
What's wrong with my project , what do I have to do to deploy it in DM Server?

If you provide actual exception it would be easier to judge. But if you say hibernate there are some issues with that. You might be better off creating a par or a scoped plan that include your war and deploy par/plan. Hibernate is not very OSGi friendly.
