Hi all,

I am receiving some issues and they seem to be revovling around persistence. I am using jBPM5.3 and jBOSS AS 7.0.2. I have done a vanilla installation. Please let me know if I am supposed to some customization as well. PFB the persistence.xml which I am using for my project and *let me know what is missing or needs to change in it*. Also I have included errors I am receiving. I am just plainly  running my project. The project needs a human task so there is one org.jbpm.task. There is one doubt as well, we are not mentioning datasource for task's persistence as well, then how can hibernate know where it should store the objects. Secondly my most of the issues are revolving around org.peristence.jpa. Kindly help me!!!!
