    Simple step by step for JBPM 5 web application

    Rajan Vij Newbie

      Hi All,


      I am new to jBPM and trying to create a web service which would initiate a said process. Starting with examples provided under jBPM installer was quite easy, but running it as web application has been a nightmare for me.


      Can someone please provide step by step document, which tells how I can create a webservice and start the process which has human tasks also.


      I am currently getting this error:


      1 May, 2012 1:04:35 PM org.apache.catalina.core.StandardWrapperValve invoke

      SEVERE: Servlet.service() for servlet Jersey Web Application threw exception

      javax.persistence.PersistenceException: No Persistence provider for EntityManager named org.jbpm.task

                at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:56)

                at org.jbpm.test.JBPMHelper.startTaskService(JBPMHelper.java:92)

                at name.brucephillips.hellows.resources.HelloResource.startUp(HelloResource.java:125)




      Attached is my web project : I have removed lib folder.
