I have a versioned object for which I'd like an error message to show up when an OptimisticLockException occurs. Adding an entry to exceptions.xml doesn't do anything because, though the OLE is thrown as seen in the log, it's subsequently caught by something. I'm not merging the object in an action method, however. The update to the object simply occurs as the result submitting a form with an inputText that is bound to a property on the versioned object. When I submit the form bound with an out-of-date object, the exception is thrown but there's no output on the page to indicate so because the OLE doesn't reach out of the Seam layer to exceptions.xml. How can I solve this? I'd think it'd be common enough that the JBoss forums would have some insight, but nothing is there on this issue! I think I could have an action method and catch the exception there, but then I'd need the additional method, which would just do a merge(). And then I'm not taking advantage of the SMPC with its mergeless updates! (But this probably applies to EXTENDED PCs too...)

[JBoss jBPM] - Re: Integration jBPM with JBoss AS 3.2.8

by alex.guizar＠jboss.com

One more thing, BPEL depends on WSEE 1.1 and JMS 1.1. The two of them are only available in JBoss 4.x. Even if you manage to make jBPM run in JBoss 3.x, you will definitely not be able to run BPEL.

[JBoss jBPM] - Re: Integration jBPM with JBoss AS 3.2.8

by alex.guizar＠jboss.com

I actually reviewed JBoss 3.2.8 to see what is in there. I deleted the jboss-hibernate.sar dir and started the server. Nothing got broken up, so I assume you can remove it if your applications do not depend on Hibernate2. Once you do this, you can throw in find class version clashes if you throw in Hibernate3. The story does not end there, tough. The jBPM console uses a web.xml descriptor that adheres to Servlet 2.4. JBoss 3.x supports Servlet 2.3 only. You'd have to migrate the descriptor and be ready for the challenge. Further, it does not make sense to develop new applications against old standards. You should probably set up a separate JBoss 4.x instance and deploy your new applications there. The advantage of this option vs. jBPM standalone is that you can leverage the enterprise features such as the web container, managed data sources, JMS, etc. Hope this helps, View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4006094#4006094 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4006094

[EJB 3.0] - TimerService Security Permissions Authorization

by elcapitan

G'day all, Can anyone direct me to ANY kind of documentation that mentions the interplay between the EJB timer service and EJB role-based security? I've got an extremely frustrating problem to do with the persistence of timers across sessions: when I create them, JBoss seems to propagate security information across to the timers, which can then call an @Timeout-annotated method in a stateless session bean - however, when JBoss is restarted, the timers persist (as expected), but whenever they time-out, they cause the log message: "ERROR [TimerImpl] Error invoking ejbTimeout: javax.ejb.EJBAccessException: Authentication failure" Any help would be much appreciated. Thanks in advance, James View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4006089#4006089 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4006089

[JBoss Seam] - Re: How to really flush data in the middle of a transaction

by x-explorer

To Gavin King, Clear explanation!! Now I understand what was wrong. I placed REQUIRES_NEW as transaction attribute. And after removing this, everything works well. And since 1.1.1 can process event after commit, I think it is the time for me to upgrade now. Thanks again.

[JBoss Seam] - Re: pagination problem, advice needed

by gavin.king＠jboss.com

You want to paginate a table inside another table???! I have never seen this done in any user interface in my life. Sounds like a bad idea. Anyway, I'm sure you could very easily do this by following the patterns used in the Query class.

[JBoss Seam] - Re: How to really flush data in the middle of a transaction

by gavin.king＠jboss.com

anonymous wrote : Don't set your MySQL transaction setting to READ UNCOMMITTED unless you really want to allow dirty reads (do you!?). I think you might've solved the wrong problem...setting READ UNCOMMITTED works because they're running in separate transactions like the previous post said. Exactly. Dirty reads are VERY BAD. Read what I wrote about them in Hibernate in Action / Java Persistence with Hibernate. anonymous wrote : Anybody have suggestions on how might you do this? Most events are processed synchronously by Seam, so you would have to be doing something "funny" to get a different transaction context. Perhaps he has an asynchronous event. Or perhaps he has no transaction at all. Or perhaps the observer method has REQUIRES_NEW. No code, can't tell. anonymous wrote : Can you just annotate observer methods with transaction attributes or is that only for session beans? An observer method can be on a session bean. And even if it is not, you can annotate methods of JavaBean components with transaction attributes in Seam 1.1. But you should not need to do this. The default behavior is to propagate the transaction, for all component types. By the way, another possibility in Seam 1.1.1 is to use an event that is processed after the transaction commit. This is an excellent way to handle refresh of session or application scoped state after the end of a conversation. The booking example uses this.

[EJB 3.0] - javax.resource.ResourceException: Transaction is not active

by trashhash

Hi Im getting javax.resource.ResourceException: Transaction is not active when this code executes. (em = EntityManager) | public getUserGoupById(Long id) { | Query dbQuery = em.createQuery("from UserGroup where id = :id"); | dbQuery.setParameter("id", id); | UserGroup ug = (UserGroup) dbQuery.getSingleResult(); | return ug //Here the exception will be thrown. | } | In debugmode Im able to see that ug is what Im looking for (right Id & name). But every time I trie to return it the exception will show. I use the same bean for getUserById(Long id), and it works fine. What could be wrong in the usergroup-case? Thanks!
