We have a simple setup where a web service is using a Dao to store data in a Database.

The Dao uses an injected persistence context. The dao is in turn injected into the webservice as a simple EJB.

This is a classic setup we have used extensively on JBoss AS 5.1.

However on JBoss 7.0.2.Final the hibernate session is closed on the second call to the web service.

I have created a simple maven project containing the problem. It uses the standard datasource from the standalone-preview configuration.

I will attach the project and server.log containing all relevant exceptions.
