It's me again,
I tried to go a step back and want to get only the jbpm SLSB to run.
After I hack against the issue
https://issues.apache.org/jira/browse/OPENEJB-971, I can start up the ejb
components of jbpm in openejb:

But when I access the SLSB I got finally into the same exception as in my first
post, when the jbpm context is built:
2009-03-12 12:46:09,068 FATAL

...
There is some part in the hibernate code to get the InitialContext:
package org.hibernate.util;
...
public final class NamingHelper
{
...
public static InitialContext getInitialContext(Properties props)
throws NamingException
{
Hashtable hash = getJndiProperties(props);
log.info("JNDI InitialContext properties:" + hash);
try
{
return hash.size() != 0 ? new InitialContext(hash) : new
InitialContext();
}
catch(NamingException e)
{
log.error("Could not obtain initial context", e);
throw e;
}
}
...
I get here an IvmContext, but it seems that this context doesn't contains the
JNDI information as the context I've build to initialize openEJB.
So I'm am lost again at the same part as before.

Marco

Betreff: AW: How to use JBPM with openEJB?
Hi David,
Thank you for your response.
I saw also that there is a stateless session bean since some version of jbpm,
but we have already a session facade to access our jbpm context. The part of
our application using jbpm is tied more to the jbpm functionalities as the SLSB
provides. Therefore it is not possible for us to move here to the jbpm SLSB,
without huge impact on the existing business logic. The code base we use,
started as a standalone application but are now going to JEE.
In the code of the jbpm SLSB I saw that we were already used nearly similar
code to access the jbpm context. The problem is that jbpm uses an own hibernate
session (version 3.2 of jbpm is tied to hibernate). This session is initialized
within JbpmConfiguration.getInstance().createJbpmContext(). You can configure
it via the jbpm.cfg.xml and hibernate.cfg.xml (settings of database properties,
transaction management etc.) which was the way if have tried and which results
in the error of my first post.
An alternative way is to set the hibernate session after the jbpm context was
created with jbpmContext.setSession(session). At the moment I investigate this
way also, but there are problems with closed session after method invokation,
and I am not sure if this way is in an save transaction state.
I hope that I have descripted our situation more clearly.
Regards,
Marco

Hi Marco,
The looking up of things from java:openejb is one of those areas that needs
improvement. Going to see if I can't get somewhere with that now.
I had a quick look at the JBMP docs and it looks like they support two modes,
one where it runs as a standalone java application and one where it runs as a
stateless ejb inside an ejb container. From the config you posted I'm guessing
you're running it as a standalone application with OpenEJB embedded inside?
Should be fine either way, just want to make sure I understand the goal as
there are likely different options one way vs the other.
