Re: Exception handling

[Poorav Chaudhari <pooravc@yahoo.com>]

Hi Rajan,

Thanks for your response. I would just like to point out that I do not have any
EJBs, anyhow I can use a similar approach with my Data access objects. can you
be a little more specific as to what you mean by application exceptions. I was
reading a write up which talked about when to throw checked exceptions and when
to throw unchecked exceptions. The article also pointed out that throwing
custom  exceptions that did nothing more than just extend the standard
Exception, was not a very smart implementation. any thoughts on that? 

Thanks.
