"Re: jBPM5.1 : Setting Process Variable from code(Using API)" To view the discussion, visit: http://community.jboss.org/message/636955#636955 -------------------------------------------------------------- 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 at org.jboss.jpa.deployment.PersistenceUnitDeployment.start(PersistenceUnitDeployment.java:310) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.jboss.reflect.plugins.introspection.ReflectionUtils.invoke(ReflectionUtils.java:59) at org.jboss.reflect.plugins.introspection.ReflectMethodInfoImpl.invoke(ReflectMethodInfoImpl.java:150) *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 -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/636955#636955] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&containerType=14&container=2034]
