[Design of JBoss Portal] - Re: Plan to improve CMS integration

by julien＠jboss.com

No need to deploy portal first anymore, I fixed the problem by adding a dependence of ACL interceptor over its session factory binder service.

Extending jBPM Visual Designer

by Achaiah

My appologies ahead of time if I am sending this to the wrong mailing list or if this question has been asked before. I am wondering if someone knows if it is possible to extend the jBPM Visual Designer with a custom set of Nodes. The current jBPM configuration is not enough for our purposes and while we can extend the Node class we have not found any documentation on how to reflect custom nodes in the graphical UI of jBPM designer. Please help. Secondly, has anyone else encountered the problem that the jBPM Visual Designer guide does not correspond to the latest version of the eclipse plugin? The current plugin does not even create a websomething.sardirectory like the guide states. The diagrams seem to be out of date as well. Thanks.

[Design of JBoss jBPM] - Re: JMS Example in 3.2 Beta

by jeffdelong

So what do you think, can we modify the NewProcessInstanceCommand to signal when there are no start tasks? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4003362#4003362 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4003362

[Design of JBoss jBPM] - Re: Can't deploy processdefinition from GPD into jBPM 3.2 -

by jeffdelong

Yes, I made the changes I described in jbpm-configs.jar. isTransactionEnabled should not be set to true; if it is not only would jBPM try to demarcate the transactions, but my understaning is jBPM would also close the hibernate session, wchich should foul everything up. You see from the the description of CMT why it is not a fit for jBPM. The web console (as currently implemented / deployed), does NOT run in / use the EJB container. Not can we guarantee that other user applications would just because they deployed jbpm-enterprise.ear (although you would expect them to). JTA is flexible because it allows for both EJB and non-EJB applications. If the jbpm-console were to be modified to only use the Command SLSB interface, then CMT might be a better fit for jBPM enterprise. As far as the documentation on getCurrentSession, in the past (in another project) it appeared to work that way. However in testing with jBPM the process deployment did not work until I set isCurrentSessionEnabled to false. You might want to test this out and see if you get the same result.

[Design of JBossCache] - Re: markNodeCurrentlyInUse() - race condition

by manik.surtani＠jboss.com

I agree that it is ugly and placing a marker directly on the node makes more sense. I also agree that using the event queue for this kind of data is pretty hacky, but let's revisit the purpose of this method (and Brian will probably have stuff to add here) markNodeCurrentlyInUse() does (should) not prevent node removal by calling one of the remove methods. All it should do is prevent the node from being evicted. And if this is the case, then a marked in the event queue should be sufficient since the event processor thread would find the in-use marker before any eviction markers. I guess where this can be a problem is if a node is marked for eviction first, and then is marked as in-use, and then the event processor thread starts.

[Design of JCA on JBoss] - JBAS-3997

by weston.price＠jboss.com

I am hesitant to see this as being required. ResourceExceptions are not, by nature, transient. We already cover the case of a connection attempt failing for validation or other reasons. The ResourceException itself is only thrown during catastrophic failure from which there is probably no possiblity of recovery. Could you please comment on what you believe to be a recoverable in this case.

[Design of JCA on JBoss] - Re: Problems JCA JMS inflow issue and tx NotSupported

by weston.price＠jboss.com

Can you confirm your simple JBM/jPBM test works with the adapter in HEAD? It should be a simple drop in replacement.
