<div class="jive-rendered-content"><p>I have no issues in installing any component. The problem seems to be revovling around persistence.xml. I think jBPM 5.x uses JPA 2.0 and Hibernate 4.x. I went through <a class="jive-link-external-small" href="http://mriet.wordpress.com/2012/04/03/jpa-2-with-drools-and-jbpm/">http://mriet.wordpress.com/2012/04/03/jpa-2-with-drools-and-jbpm/</a> and made requiste changes. I have made following changes:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><ol><li>Commented  <mapping-file>META-INF/ProcessInstanceInfo.hbm.xml</mapping-file>. Now the question is do I need to remove this file from the META-INF folder of project as well.</li><li>changed 1.0 to 2.0 and _1_.0 to _2_.0 to at required places.</li><li>changed JBPMorm.xml to JBPMorm-JPA2.xml.. I have added this file to the META-INF folder of the project as well, let me know if this file needs to be modified as well as I have seen in this thread <a class="jive-link-message-small" href="https://community.jboss.org/message/739318#739318">https://community.jboss.org/message/739318#739318</a></li><li>Changed the transaction manager as well as mentioned.</li></ol><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p style="text-align: start;">Although I am rid of these errors, but new ones have cropped up.
