JTA does not rollback transaction when RuntimeException thrown in another bean?

[alireza alallah]

We have 3 EJB to handle our business, as below:   

    @Stateless

    public class BeanA {

        @PersistenceContext(unitName = "primary")

        private EntityManager em;

        @EJB private BeanB beanB;

        public void handle() {

          EntityA entity= new EntityA();

          ....

          beanB.handle();

          em.persist(entity); //Transaction does not rollback and saved entity

        }

     } 

    @Stateless

    public class BeanB {

         @EJB private BeanC beanC;

         public void handle() {

            beanC.handle();

         }

    }

    @Stateless

    public class BeanC {

         public void handle() {

            try {

               throw new RunTimeException("error occurred!!");      

            } catch(RunTimeException e) {

                e.printStacktrace();

            }

         }

    }

According to JTA concept that if occurred RuntimeExcpetion the current transaction will be rollback,I expected that above transaction should be rollback but does not rollback. also we use Wildfly10 as Application server and active JTA="true" option in datasources.

Is there any idea about this problem?

I don't know if this is a problem in the sample code you pasted or it really is an issue in your application, but, there's really no exception being thrown since, the exception is just being caught and the stacktrace printed out:

try {

               throw new RunTimeException("error occurred!!");      

            } catch(RunTimeException e) {

                e.printStacktrace();

            }

So it's pretty much as if there's no exception

Also I think you should add the @Transactional annotation on the BeanA::handle()

I think that in EJB by default is transactional , I am right?

[alireza alallah]

In above example if modify my code as below:

@Stateless

    public class BeanA {

        @PersistenceContext(unitName = "primary")

        private EntityManager em;

        @EJB private BeanB beanB;

        public void handle() {

          EntityA entity= new EntityA();

          ....

        try {

               throw new RunTimeException("error occurred!!");     

            } catch(RunTimeException e) {

                e.printStacktrace();

               }

          em.persist(entity); //Transaction does not rollback and saved entity

        }

     }

Then container thrown exception that Transaction is not present

That's correct.

Then container thrown exception that Transaction is not present

Please post the complete exception stacktrace and the client code where you do the lookup and invocation on the EJB.
