[jboss-dev-forums] [Design of JBoss jBPM] - Re: MessageService and JMS

[mteira]

Hello.

1.-I've found the problem with JSF and jbpm.ear. It was my fault (once again). It seems that the cause was that, perhaps for not running the clean target, the ear customizedwar lib directory was holding both a Sun JSF implementation and a MyFaces apache one. I suppose that the implementation was switched in some moment, and I didn't clean up my target directory as frequently as I should.  BTW, deploying the jbpm-console.war and the jbpm.ear (with the 'web' node commented out) at the same time was not a valid workaround, as I run into problems with the ehcache (it looked like an NPE trying to create a second CacheManager).

2.-Before trying to setup a working cactus environment, I just wanted to create an standalone JMS client and just send a message to the JbpmCommandQueue to see how it works. 
 
I run into some problems with the MDB CommandListener trying to locate the  CommandService Session Bean. I patched as:

I'm not running into some problems with hibernate that is not able to locate using JNDI the UserTransaction. I will investigate further, to see if it's caused by a missconfiguration.

Regards.
