[jBPM Users] - Samples for calling BPEL process from Java
by bpel-way
I'm looking for samples/examples for how to call BPEL process from Java. I want to have a webpage in JSP and exchange messages with a BPEL process. I've looked all over the documentation available on this site, and also elsewhere; but, couldn't find anything useful. I must have missed something. Please help.
In case it helps, I'm using: JBossAS 4.2.3GA, JBPM-BPEL1.1.1, JDK 1.5, JWSDP2.0, MySQL5.1, Ant1.7.1.
I'm new to this technology, and so far, I've been in successful in configuring MySQL to work with JBoss (very good documentation available here). I've been successful in creating some of my own processes (beginner level) and successfully deploy and test run them. Now, I've this scenario of calling a BPEL process from webpage.
Thanks in advance.

[Installation, Configuration & Deployment] - 4.0.5GA - JMS not working, clustered environment
by byF
Hi!
We are having troubles with JMS in "all" instance of JBoss. We have 2 JBoss server in cluster with Apache&Mod-JK load balancer. Those 2 nodes operates as operational and standby node (so not classical load balancing). The architecture is simple: Web node comunnicates through JMS with another servers behind firewall. Before putting nodes into cluster we were using "default" configuration and JMS worked correctly.
Now the problem, I've moved our app into "all" instance (because of clustering) and JMS has stopped working with such exception:

I've done some digging and found that I cannot use "QueueConnectionFactory" as JNDI name when doing the lookup, but "java:/JmsXA". When I tried, I've obtained this:
