Don't expect a document describing the steps to build your application.
The error that you are getting is not even a JBPM error, it's a JPA one, so you can try to find out what's is happening. Usually you get that error when you don't have Hibernate or any JPA provider inside your application classpath. Are you using Maven? if not you will need to add hibernate and all its dependencies to the classpath.
Ok, what I wanted to ask was how do I move my human task(the one available with eclipse plugin) application to jboss server as 7. I couldn't find a single example which talks about moving human task application to jboss as 7.
+ I have created a simple Rest web service in which when I try to call human task process, it doesn't works. Why? I am using same persistence xml and jndi is defined in standalone.xml.
I am new to jBPM and hibernate and thus facing several issues so it would be realy great if you could atleast confirm below is correct, if not provide steps to use create a web application using existing java:jboss/datasources/jbpmDS.
I have created dynamic web project in which I define class for rest web service and move code of human task application accordingly into the application.
But it still get exceptions like
: Entity manager could not be created for "org.hibernate.persistence.jpa"
: Datasource could not be found.
How's task get persisted when I run human taska project using eclipse?
Do we have an application available where in I could just code and deploy that. A kinda sample.war that has persistence.xml defined for using java:jboss/datasources/jbpmDS
Thanks in advance.

I got the same errors mentioned by you in your first message. Mauricio's reply was helpful in knowing about the cause.
But unfortunately I was unable to rectify the error as I am new to Hibernate concept. Luckily there was help from bpmn2user
in one of his blog articles which explains in detail for introducing persistence. Please find the link below.
Hello Process ( without persistence )
Hello Process ( without persistence but having a task server created )
Hello Process ( with persistence )
I did try the one with persistence. But there were error messages related to Bitronix Transaction Manager. I don't have the
error messages with me rigt now. I will post it tomorrow with more details.
You may also want to check bpmn2user's blog which has several interesting and informative articles explained very well.
Hope this helps.
