Hallo,
i've got my web application war originally developed under Tomcat and I'm experiencing issues with JBoss deploying. My scenario gives me no access to modify JBoss common/lib presence so the only chance I've got is to add the right descriptor jboss-classloading.xml to my WEB-INF to instruct the classloader to give precedence to my web-inf/lib.
My web app uses Hibernate 3.5 jars as well as Struts 1.3.10 and other framework. I defined this classloader tag:
[code]
<classloading xmlns="urn:jboss:classloading:1.0"
domain="WebReportFFDeploy.war"
export-all="NON_EMPTY"
import-all="true"
parent-first="false" >
</classloading>
[/code]
where domain is my war name but this not fix my issue. Jboss still uses the hibernate jar in common lib to solve classes ignoring my hibernate jars in my web-inf/lib (I used a new method present only in the last version of Hibernate. Hibernate version present in JBoss can do the same using a deprecated method and I really don't want to touch the code). My goal is to give higher precedence to my web-inf/lib to avoid conflicts in version and dependencies. I'm newbie at JBoss but this issue is becoming too time consuming for me. I hope that JBoss community documentation will add soon tutorial and examples to explain this descriptors in a clear way.
Thanks a lot
Simon
P.S. Please note that at the moment I get a sessionfactory binding an Hibernate Util class to my web application listener. I hope this doesn't cause other issues thought I will soon bind to a JNDI resource.

[jBPM] - Question: Running JBPM on JBOSS AS 6

"Question: Running JBPM on JBOSS AS 6"

--------------------------------------------------------------
Hello,
I want to run an JEE(6) application on my JBOSS AS 6 server using JBPM 3 (incl. persistence to MySQL DB). I want this app to be scalable, support clustering, workflow resume after restart etc. From what I read on various JBOSS documents and other sites, the best way to do so is use the jbpm-enterprise.ear. So I tried getting that to work, but have several issues. So I hope some experts on this formum could provide answers to the questions below:
1/ Is there a (newbie) tutorial on how to get the ear deployed on JBOSS AS 6 and use I. The ear as-is can't be deployed on AS6 due to a syntax error in a TLD file or so (JBOSS AS log).
2/ Is using the command bean in the ear the right way to do this?
3/ Is there a tutorial available on ear file usage and Hibernate persistence, CMP, transactions etc ?
4/ Are there any design patterns for development of a JEE(6) app using JBPM 3 in eclipse?
5/ What about JBPM5 and eclipse. Would JBPM5 be the better choice to start with? I read that the tools for eclipse still don't support version 5 and that the version hasn't reached the maturity of version 3 yet.
All help is really appreciated.
Regards,
Sven.

[jBPM] - JBPM5 configuration for Oracle in production

Hello,
I want to deploy JBPM in production using persistence of processes and human tasks in an Oracle database. I have changed in the persistence.xml and hiberante.cfg.xml file the H2 database connection configuration by Oracle configuration.
We encounter the following exceptions while listing Processes in the jbpm-console :
Caused by: javax.persistence.PersistenceException: [PersistenceUnit: org.drools.persistence.jpa] Unable to build EntityManagerFactory
...
Caused by: org.hibernate.HibernateException: The chosen transaction strategy requires access to the JTA TransactionManager
What is the jar involved ?
The JBPM 5 involved a lot of components. For production use, we want a minimal deployment at first time.
We want to cut dependency with a drools-guvnor repository, and obtain the processes definition from file system.
How can we achieve that ?
Can we change only the ChangeSet.xml in jbpm-gwt-core-5.0.0.jar ?
Thanks in advance,

The following error message that we got from the server log.
