Question

I would like to know if the EJB container has impact on method calls withing an EJB. I’m not sure if @TransactionAttributes annotations or any other annotation has effect in this case or not. If it has, how it is implemented in the container?

@Stateless
public class MyBean {   

  public void doSomething() {
    // logic
    doSomethingElse();
    // logic
  }

  @TransactionAttribute(TransactionAttributeType.NOT_SUPORTED)
  public void doSomethingElse() {
    // logic
  }
}

Answer 1

Plain java call to doSomethingElse() is not handled by the container. If you want to make an “EJB-call” then you should use SessionContext.getBusinessMethod(…):

sessionContext.getBusinessObject(MyBean.class).doSomethingElse();
