Exception handling when invoke ejb

Question

Hi,
I call ejb like this:
try {
      MyBeanHome beanHome = .. //jndi lookup 
      MyBean bean = beanHome .create();
      HashMap h = bean.chargeFee(data);
      bean.remove();
} catch (
}there are a lot exceptions: NamingException, CreationException, RemoteException, RemoveException (I don't have application exception).
I am thinking I catch the RemoveException first, since it happened after the chargeFee is called, and chargeFee is already been executed, so I deal it differently with the other Exceptions, since they heppend before or during the chargeFee executed, I treat it as not been executed.
Is it the right way to handle the exceptions? Thanks

It's difficult to answer you question because the intent is not known.
I would suggest to write down all possible exceptions and the actions to be taken. Try to pass on as many exceptions as possible to the client. I know I might be getting a lot for flake for this statement but catching too many exception makes the code look complicated. If you don't know what to do with an exception then just don't catch it.
If Pet Store example is complicated for you then try looking at Avitek Medical records example that comes bundled with BEA weblogic 8.1. You can install it for free and the example is just great.
