How do I setRollBackOnly on a sessionBean using CMT and JTA

I am new to J2EE v5 and I am trying to understand how CMT and JTA work
I want to rollback a transaction in Stateless SessionBean and all the documentation I have read is that I should use setRollBack on the EJBContext.
I have created a testcase where I increment a number in the DB, call the persist on the EntityManager and then try to roll it back using em.getTransaction().setRollbackOnly(); . When I do this I get returned an error
I used netbeans 6.5 to create the sessionbean and the corresponding enity
Below is my session bean
I would appreciate if someone could put me on the right track and even post an example session bean that I could use as a template.
