When running in a SLSB you should be able to access it's JNDI
namespace. To do that the InitialContext needs to be constructed with
no (or empty) properties. Then you should be able add a <resource-
ref> like:
<resource-ref>
<res-ref-name>TestDS</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
</resource-ref>
And then look it up from within the SLSB with 'java:comp/env/TestDS'

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

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.

Hi experts,
I try to get JBPM working with openEJB. The problem is that JBPM
cannot get the datasource for the hibernate session.
As far as I found out is that the JBPM uses an own InitialContext.
I try to configure the same initial context properties as for the
direct initial context lookup like (part of the hibernate.cfg.xml):
<hibernate-configuration>
<session-factory>
<property name="hibernate.connection.datasource">java:openejb/
Resource/TestDS</property>
<property
name
=
"hibernate
.jndi
.java
.naming
.factory
.initial">org.apache.openejb.client.LocalInitialContextFactory</
property>
<property
name="hibernate.jndi.openejb.deployments.classpath.ear">true</
property>
<property
name="hibernate.jndi.openejb.jndiname.format">{deploymentId}/
{interfaceType.annotationName}</property>
<property name="hibernate.jndi.openejb.altdd.prefix">test</
property>
<property
name="hibernate.jndi.openejb.validation.output.level">VERBOSE</
property>
...
Also I found out the the database is registered under "java:openejb/
Resource/TestDS", where I can access it via lookup in the initial
context, but it's not there as jbpm build this session.
Here also a part of the stack trace:

I'm using openEJB 3.1 and JBPM 3.2.5.SP2.
I hope someone knows how to use JBPM within openEJB or can give me a
hint.
