[JBoss jBPM] - multiple engines
by msandoz
i am new to jbpm. are there any problems with multiple copies of jbpm running against the same database? will there be any state inconsistencies?
also what would be the preferred method of having jms clients act as the workers for various nodes? heres my scenario:
1. client submits a flow and creates an instance of it.
2. the flow contains some kind of node that indicates it should perform some action given certain data
3. a jms message is sent out so that some listening processor can do the processing and return the variables in another jms message
4. the flow continues
would i best put together a new node type or custom handler? is there something built-in that will handle this? also i was looking at my installation and didnt see any jbpm ejb client examples - is there another package somewhere for those?

[JBoss Seam] - Seam CVS+JBoss 4.2+Trinidad
by smithbstl
I am having some problems getting Trinidad working with a SeamGen created project (Seam CVS) and JBoss 4.2
This used to work with Seam 1.2.1GA and JBoss 4.0.4 and MyFaces.
Every time I open a Trinidad page I get this stack trace. It has something to do with the A4J Filter. I am not using Ajax4JSF in my project, it was just included with SeamGen.

[EJB/JBoss] - Basic question about IIOP
by HibsMax
Hi, Folks.
Sorry for the crosspost. I posted this question on another forum but found out that it should probably have been posted here (as per this thread : http://www.jboss.com/index.html?module=bb&op=viewtopic&t=58934). Anyway, here is the original question:
=============
Hi, Group.
Apologies if this question is to vague or scant on details, I am very new to this sort of stuff and I've not been able to find out much online. Perhaps I am using the incorrect search terms or something.
I have a servlet that sends various messages to an EJB running on another server. The protocol used is IIOP. When I access the servlet, I get this error message on my stdout:
javax.naming.NamingException: Failed to retrieve Naming interface [Root exception is java.net.MalformedURLException: unknown protocol: iiop]
I am setting the Context.INITIAL_CONTEXT_FACTORY to:
org.jboss.naming.HttpNamingContextFactory
and I also tried:
org.jboss.iiop.naming.ORBInitialContextFactory
I've scanned through the JBoss Admin Guide (4.2 by the way) and I get the impression that this should work without further /much configuration but that's just a guess really. Can anyone shed any light on this or point me in the correct direction? I feel like this should be soo simple and it probably is. :)
My server is based on the all configuration.
=============
Peace, Anders
