Re: Instantiating a process in JBPM5

I'm now setting up jbpm more traditionally through jbpm. The aim is to have it embedded in my app. When I try to create my entity manager to instantiate the task service though, I get the following exception:

 

javax.persistence.PersistenceException: [PersistenceUnit: org.jbpm.persistence.jpa] class or package not found

        at org.hibernate.ejb.Ejb3Configuration.addNamedAnnotatedClasses(Ejb3Configuration.java:1092)

        at org.hibernate.ejb.Ejb3Configuration.addClassesToSessionFactory(Ejb3Configuration.java:871)

        at org.hibernate.ejb.Ejb3Configuration.configure(Ejb3Configuration.java:758)

        at org.hibernate.ejb.Ejb3Configuration.configure(Ejb3Configuration.java:191)

        at org.hibernate.ejb.Ejb3Configuration.configure(Ejb3Configuration.java:253)

Caused by: java.lang.ClassNotFoundException: org.drools.task.query.TaskSummary

        at java.net.URLClassLoader$1.run(URLClassLoader.java:217)

        at java.security.AccessController.doPrivileged(Native Method)

        at java.net.URLClassLoader.findClass(URLClassLoader.java:205)

        at java.lang.ClassLoader.loadClass(ClassLoader.java:321)

 

 

The exception is obvious, but I had two questions:

 

1- Which jar has this class and where to I download it. I already have drools core and compiler jars.

2- Why do I need this jar. I think I have everything I need according to the documentation.

 

 

Thanks in advance for your help.
