I am having some trouble with deploying a jar project that contains all of my base code into multiple webapps.
If i deploy my code in a jar inside a war i get a NoClassDefFound Exception while spring is intializing my beans. The class that is not found is net.sf.hibernate.Session, which doesn’t really make sense as i am using hibernate3. The session it should be loading is org.hibernate.Session.
If i deploy the code directly in the webapp, in the WEB-INF/classes directory this problem goes away and the app deploys and works as normal.
Does anyone have any idea what my problem might be?

nope, no reference to net.sf.hibernate at all, and all of my spring references use the org.springframework.orm.hibernate3 package where needed.

Sorry for the delay nikhil, this one stumped me and I went around asking the Hibernate and Spring guys what they thought it might be, no one knew for sure but the Spring team did let me know that there has been many bug fixes to Hibernate/Spring from the 4.0M3 release you are using and 4.0.3. They also mentioned a lot more fixes have gone into 4.1M2 that will be out this week (Milestone release though).
I know that we specifically had an issue with the Spring libraries we were packaging during the early 4.0 dev cycle, so I’m wondering if that is the problem.
