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 but doing the same configuration Jboss 5.0.0 GA now
Thanks and Regards,
