eclipse - jBPM6.3+Hibernate4+Tomcat7+JPA2.0Exception: Unable to build EntityManagerFactory -

i trying make this example work me. since jbpm version 6.3.0.final, this solution absolutely won't solve problem.

my scenario is, firstly, created jpa & dynamic web project using eclipse mars1, , copied example files new project, modified taskprocessservlet.java, shown below, because of obsoleteness , deprecation of runtimepart in original servlet code. when built project , ran on independent tomcat 7.0.64 other server inside of eclipse, , jsp showed without problem, when clicked create processwhich fire taskprocessservlet, got error message:

error:[persistenceunit: org.jbpm.persistence.jpa] unable build entitymanagerfactory 

would postgresql-9.4.1207.jar(for tomcat8) problem? don't think because kept getting same error in tomcat 8, downgrade tomcat 8.0.30 tomcat 7.0.64.

i'm able run jbpm-console jboss both on tomcat 8 , 7. jbpm-console interfere project?

how tackle problem?

any idea appreciated, thank much.

thanks anton giertli, thank attention.

i've solved problem after modifying server.xml , adding hibernate.cfg.xml jpa referring here.

but still had consequential issues need figure out.

thank way.
