I have two questins, 1. Why do we need so many persistence.xml? 2. *In lib folder,* persistence .xml found in two placess (jbpm-5.3.0.Final-human-task-war and jbpm-human-task-war-5.3.0.Final ) in these files using  JBossTransactionManagerLookup. <property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.JBossTransactionManagerLookup" /> *but in db folder,* one persistence.xml found this using JBPMTransactionManager.      <!-- for AS7 -->       <property name="hibernate.transaction.manager_lookup_class" value="org.jbpm.integration.console.JBPMTransactionManager" /> question is, what is the difference between these transaction manager, and these two transaction managers work together. some tips will be appriciated.... thanks, -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/750239#750239] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
