Thanks Jack
I solved the problem and later I checked your response. Along with jta.jar and btm.jar,sl4j jar has to removed and should be present in tomcat lib.

1.) I am trying to run my example in JBoss AS (5.0.0 GA) now but I am not sure how to do configurations in JBoss.
*Could anyone give some reference?*

2.) When I tried doing an error occured saying : 
java.lang.RuntimeException: Specification violation [EJB3 JPA 6.2.1.2] - You have not defined a jta-data-source for a JTA enabled persistence context named: org.jbpm.task
 at org.jboss.jpa.deployment.PersistenceUnitInfoImpl.<init>(PersistenceUnitInfoImpl.java:115)
 at org.jboss.jpa.deployment.PersistenceUnitDeployment.start(PersistenceUnitDeployment.java:285)

I changed following in persistence.xml  as
Before
......






<persistence-unit name=++"org.jbpm.task"++> 

<provider>org.hibernate.ejb.HibernatePersistence</provider> 

<jta-data-source>java:jdbc/testDS1</jta-data-source> 

<class>org.jbpm.task.Attachment</class> 

<class>org.jbpm.task.Content</class>

..........

After changes :
......





<persistence-unit name=+"org.jbpm.task"+>
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<jta-data-source>java:jdbc/testDS1</jta-data-source>
<class>org.jbpm.task.Attachment</class>
<class>org.jbpm.task.Content</class>
..........

But now error is coming as java.lang.ClassCastException




: org.hibernate.ejb.HibernatePersistence cannot be cast to javax.persistence.spi.PersistenceProvider

*Could anyone suggest what went wrong and how to solve it?*

PS:  I am using the example in article :  http://community.jboss.org/people/bpmn2user/blog/2011/09/21/jbpm5-web-example http://community.jboss.org/people/bpmn2user/blog/2011/09/21/jbpm5-web-example but doing the same configuration Jboss 5.0.0 GA now

Thanks and Regards,
Sandeep
