Hi Joonas,
I think we need more details about your problem because I cannot
reproduce it
here is the test I made:
b1 is an entitybean BMP
b2 is an entitybean CMP
try {
utx.begin();
b1.doAppException_1(); // throw an application Exception
int num = b2.getNumber();
utx.commit();
Test.testFAIL("Test 1 ");
}catch (Exception e) {
try {
utx.rollback();
}catch (Exception ex) {
System.out.println(ex);
Test.testFAIL("Test 1: "+ex);
}
}
Test.testPASS("Test 1");
}
This test pass without problem. It is the same if the business method
called on b1 throws an UncheckedException or RemoteException or
EJBException.
What is the difference with your try?
Best regards,
