[jboss-user] [EJB 3.0] - Transaction issue with separate JBoss jars

Note: I'm told this is really an EJB3/JPA issue, so I'm posting it here now. Sorry for the *triple* post. Running JBossAS-4.0.5.GA on Sun JDK 1.5.0_07 on RHEL3. Recently we have tried to separate our EJB Project out into two parts. One project to handle all of our persistence and another to handle all of our service's. The persistence project was set up to serve out entity objects back through a DAO service. This way our Service project can just call into our DAO services and retrieve the information that they would need and allowing for a nice split between two different types of projects. However, in the process of separating these projects out we hit some issues with the transaction manager not flushing upon the call of the flush command. The flush command is something we greatly rely on as a means to make sure our data is persisted underneath the proper user in the database through contexts. It is also the means in which we can allow support of oracle proxy connections. We achieved this by having a PrepareDatabaseConnection AOP method; which is executed before and after a method is called. Allowing for us to set the database context after the transaction is started and to close the database context before the transaction ends. Ideally we would have liked to hook it directly onto the begging and end of the transaction but we couldn't find a great way to do so. So instead on every one of our services and DAO work we added the PrepareDatabaseConnection interceptor to properly set our database context or to configure the connection as a proxy connection. In a single jar this functionality works great. However, in separate jars we start to see issues with the database context not being properly set, which leads to issues with auditing what users changed the data in the database. In a single jar the contents flush upon my call to the entity manager to commit / update the information. However, when these are separate jars the flush doesn't occur until the transaction manager tells it to flush and close the transaction. At which point in time the database context has already been unset leaving no record of which user was actually using that connection from the connection pool. Why is it when we move the database code out to a separate jar the entity managers flush doesn't actually flush the information when it was requested to?
