Hi
We have trouble with Jpbm5.1 on Weblogic 10.3.4 and Oracle database. The problem is with
HumanTask and persistent. For the moment we are able to create HumanTasks, but not able to
"fetch" them and complete them. Does someone have a workling sample of jbpm5.1
(or 5.2) for Weblogic. Interestet in looking at at persistence.xml file and the code to
setup the HumanTask server. Adding our files here, so if some smart jbpm people can se
what we are doing wrong, we wold have a happy X-mas..
Config from persistance.xml
<property name=+"hibernate.connection.datasource"+
value=+"jdbc/jbpm"+ />
<property name=+"hibernate.max_fetch_depth"+ value=+"3"+ />
<property name=+"hibernate.hbm2ddl.auto"+ value=+"create-drop"+
/>
<property name=+"hibernate.show_sql"+ value=+"true"+ />
<property name=+"hibernate.transaction.manager_lookup_class"+
value=+"org.hibernate.transaction.WeblogicTransactionManagerLookup"+ />
<property name=+"hibernate.dialect"+
value=+"org.hibernate.dialect.OracleDialect"+ />
<property
name=+"hibernate.connection.autocommit"+ value=+"false"+ />

Isn't there any other error log? If not, you can debug the server classes
(TaskServerHandler for example) and check the cause of the error.

Strange.. I have configured jbpm into weblogic into the past. I recommend debugging the
server (from TaskServerHandler, TaskServiceSession) classes, as you will find our the root
cause of this "could not execute query "

Can you share som files with us? I am VERY interested in seeing your persistance.xml, your
code to setup HumanTask server and dependencies in your pom. Mybe you can save our x-mas
holyday....

Hi Thomas, I'd be glad to share it, but honestly I don't have it, it was in
client's repository.
Anyway, to solve this issue, you should check the server exception checkinhg the sysout
and syserr as Maciej said, or debugging this code to check the exception.

We can now start up a new porcess with HumanTaks and Session persistence, but...
SessionInfo never gets written to the database (HumanTask is persisted ok). The result is
that when we try to load the session again it fails - this is excpected since we can not
wrtite to the database.
(We are starting Jbpm5 for a EJB context)
The problem now (which we can se in the Hibernate log)
[05/01/12 03:33:12:012 CET] DEBUG ast.ErrorCounter: throwQueryException() : no errors

I think this come for the setup of the Environment:
ttlog.logDebug("Creating EntityManagerFactory for persistant session");
EntityManagerFactory emf =
Persistence.+createEntityManagerFactory+("org.jbpm.session");
Environment env = KnowledgeBaseFactory.+newEnvironment+();
env.set(EnvironmentName.+ENTITY_MANAGER_FACTORY+, emf);
When running i Junit mode (java SE we can use Bitronix and the line under works
fine
env.set(EnvironmentName.TRANSACTION_MANAGER,
TransactionManagerServices.getTransactionManager());
Do someone now how we can do the same in WLS? Or must we do someting else to tell Jbpm
where to find the transaction manager?

Thomas, seems like transaction manager can't be obtained with out of the box
mechanism, what you could try is to set transaction manager in environment in the same way
as for JUnit tests:
* use initial context look up if you know JNDI name where transaction manager is bound to
on WebLogic
* use
http://docs.oracle.com/cd/E11035_01/wls100/javadocs/weblogic/transaction/...
TransactionHelper class from WebLogic to obtain it
BTW, can you find following log entry just after exception that you shared with us:
JTA TransactionManager found at fallback JNDI location

Hi again..
After some more log study it looks like WebLogic transaction manager is avaliable at
jta.TransactionManager: java:weblogic/TransactionManager
So the question is how to tell Jpbm to look at this location.
do you know?

I am afraid jBPM does not have such functionality at the moment, I mean just to inform it
about JNDI name for transaction manager. It has several fallback names configured but they
are final. With slight modification to the code base it could be done, but probably you
are interested in changing the code base, at least not at the moment, right?
Since you know the exact JNDI name you can just look it up and set on the environment when
creating sessions.
P.S.
Could be a good candidate for an enhancement to provide a mechanism that will allow to set
custom JNDI names for some runtime components, such as transaction manger.

How do you start the task server - is it deployed to the WLS as well?
The exception (stack trace) that you attached is from client side (task client) and the
error happened on server side (task server). Maybe you can take a look at the sysout and
syserr of the task server process if it is not deployed to WLS.
