Thanks Santanu.

I have changed spring-transaction-interceptor from current="true" to current="false" and it did resolve that issue.

Now , when i start a new process, it gives me

org.jbpm.api.JbpmException: no org.jbpm.pvm.internal.session.DbSession in current environment

I am using the following code

@Transactional(propagation = Propagation.REQUIRED, rollbackFor = Exception.class)
@Override
public void startProcess(String processName, Map variables)
{
executionService.startProcessInstanceByKey (processName, variables);
}

and the config file has db session as shown below

<transaction-context>
<repository-session />
<pvm-db-session />
<job-db-session />
<task-db-session />
<message-session />
<timer-session />
<history-session />


<hibernate-session />

<hibernate-session current="true" />
<identity-session />
</transaction-context>


Can you let me know if somethings wrong ?

Also to add, i have a Spring advice

<tx:advice id="txAdvice" transaction-manager="txManager">
<tx:attributes>
<tx:method name="get*" read-only="true" propagation="SUPPORTS" />
<tx:method name="find*" read-only="true" propagation="SUPPORTS" />
<tx:method name="*" propagation="REQUIRED" />
</tx:attributes>
</tx:advice>

It will be helpful if you can provide the stack trace

Hi Santanu

I tried your jbpm configuration. I did not get the exception, but it did not work also. I got stuck after firing one select. It looked like a deadlock. However the problem I notices in you jbpm.cfg.xml is presence of "hibernate-session" twice. I used the second one (with curent=true) successfully.

I changed that already (only one hibernate-session with client = true ) but same result. No clue at why i am able to deploy but not start ?
Googled/Binged it , could find much .. Stuck on it ..

I am getting DBSession error due to this error --

I'm pretty sure that this exception appears to be the cause of another that happens before... try to debug your code in order to find the original exception

Only change i have is
<command-service name="txRequiredCommandService">
<retry-interceptor />
<environment-interceptor />
<spring-transaction-interceptor current="false"/>

Previous working code was with 4.0 and following

<command-service >
<retry-interceptor />
<environment-interceptor />
<spring-transaction-interceptor current="true"/>

Not sure if spring-transaction-interceptor = false makes the session close ?? Will redo everything again :(

Rolled back everything to as it was JBPM 4CR1 with New instance of Jboss 5.0, still same error - i am so frustated

Just a update -
It works fine with 4.0 jars - above error were because still had 4.2 jars in lib..

I will stick with 4 until i hear more from anyone.

Rocker,
are you missing db id generator in your jbpm.cfg.xml file?

 <object class="org.jbpm.pvm.internal.id.DatabaseDbidGenerator">
 <field name="commandService"><ref object="txRequiredCommandService" /></field>
 </object>

 <object class="org.jbpm.pvm.internal.id.DatabaseIdComposer" init="eager" />

I had DBIdGenerator in my config , i rolled back everything to see whats causing the problem ..

May be i had id-generator in my config + hibernate-configuration as you said. Not sure if this was causing the Spring session to be closed after creating id ? I will try it and let you know .. Thanks.

One way to debug may be to put a breakpoint in Hibernate SessionImpl.close() method. And then look down the stack to find out what has resulted in that close call.

You were right .. those 2 changes were the culprits .. I upgraded from 4 to 4.2 + deployed on WL 9.2
Now if you could let me know how to resolve this issue -
