How to avoid loading Drools and Hibernate classes

captainvoid Nov 11, 2011 8:03 AM

Hi,
I'm having an issue that only became obvious with the last Weld 1.1.3.Final release which changed the log level for classloading problems:
On container startup, several ClassNotFoundExceptions are logged, due to missing Drools and Hibernate classes.
I don't use database persistence nor transactions, so I don't have hibernate in my classpath (my app is running on Tomcat 6).

The web app is deployed and works. Just these exceptions are a bit annoying.

Here the stacktrace:

May I have to disable more beans to get rid of these exceptions?
Any tip is welcome. Thank you.

For each of those, they should have the @Requires class on them with the needed class. Would you please open a JIRA for these with the attached stack traces?

2. Re: How to avoid loading Drools and Hibernate classes

captainvoid Nov 24, 2011 6:45 AM (in response to captainvoid)

Sorry for the delay..

I tracked this down a little bit more in detail and it turns out that there two dependency issues with several Seam modules involved:

In seam-faces there is a class TransactionPhaseListener with @Requires({ org.jboss.seam.persistence.PersistenceContextsImpl, org.jboss.seam.transaction.TransactionExtension })
So this means that the bean should only be installed if the seam-persistence implementation and the seam-transaction implementation classes are present.
However, seam-transaction-api.jar and seam-persistence-api.jar have to be present because TransactionPhaseListener directly references classes from these modules.

And here comes the culprit: seam-persistence-api.jar contains a class SeamManagedHibernateSessionCreated which is an event and depends on Hibernate (org.hibernate.Session). Weld somehow needs to read this event class, doesn't find hibernate and complains.

So is this a dependency issue with seam-persistence I guess?? Worth a JIRA issue?

The second issue is the drools dependency of class RuleBasedPermissionResolver in seam-security. This class has @Requires(org.drools.KnowledgeBase) but at the same time directly uses drools classes. My question is if the @Requires annotation is supposed to work event if the class imports classes which are not present at runtime? It doesn't seem so, but I don't believe that this a bug, correct me if I'm wrong. Same thing, not sure about the JIRA issue..

Thanks for commenting on this Jason, if you have a moment!

lightguard Nov 24, 2011 3:35 PM (in response to captainvoid)

We need to modify the modules a bit I think. This is probably an issue with the container and loading classes, but we should create archives w/o those dependencies. Could you please create JIRAs for these issues in their respective locations?

Any update or fix for this? It makes life harder seeing those stack traces. If I change logging level, I could be missing some important warnings/errors.

Those are info level messages, and I'm not 100% sure where they're coming from. I know it's desired to have a clean startup, but those ones can safely be ignored.

Hi Jason, But they show up as stack traces. I got few developers complaining and it makes it takes extra time to read through console to see if they're real errors or not. Like I said even if I change log level config and supress these messages I could be missing other important log message from the same package.

Whatever is causing these exceptions should handle them and not let them bubble up if they're not important. Or log them in debug mode.Does not that makes more sense?

lightguard Dec 13, 2011 2:47 PM (in response to captainvoid)

I don't know where they're coming from. The stack trace doesn't tell me which class is being loaded when it can't find the class. The Velocity one is interesting because I know that one is broken up (assuming you're using Seam Mail) so if you don't have Velocity in your project, don't use the module. The Drools one is somewhere in Security, but I'm not sure. Hibernate is all over the place in Persistence. It's actually not Seam that's doing the loading and logging the issues, but it's Weld / AS.

The ultimate solution, I think, would be to split those out and add them as other parts of the modules like Seam Mail did. However, that won't be happening for 3.1.0.Final (it's due out later this week).
