Transaction error handling

[joeho]

Dear all,

I try to capture error and throw as an application error. But the EJB will not do rollback in this case. I have tried to use setRollBackonly() only to do the rollback but still application error cannot be throw. (I guess setRollback() will throw runtime error also).

How can I rollback the transaction with throwing application error since I need to throw my own error code?

Thanks a lot

Joe

The short answer is don't throw Runtime or Remote
exceptions and use setRollbackOnly.

But the problem when I use setRollback only, it will throw runtime exception e.g.
...
catch{
setRollbackonly();
throw AppException();
}
...

Runtime exception was thrown automatically and cannot reach "throw AppException()"

Thanks

What runtime exception is it throwing?

Are you sure AppException isn't a RuntimeException?

I have tried this in session bean:
try{
...
//call entity bean here
...
}
catch
{
setRollbackOnly();
System.out.println("After roll back");
throw AppException();
}
...

I cannot get the message in log and nullpointer exception was received in caller session bean.

Thanks

That isn't even valid java :-)

Which version are you using, I know there
was some tidying up of the Exception handling in 3.0.1

If you still have a problem, can you post a simple
jar (with source) that illustrates it?

I have solved the problem. It is because I cannot get the correct sessioncontext. Then error occurred at 'sessioncontext.setRollbackOnly()' and nullpointerException was thrown.

Warjort, thank you for your help!!
