Exception reporting through JPA

[Shridhar Raghavan]

Hi,

I am using JPA for persistence. While developing my application i need to be able identify the invividual exceptions thrown to apply differing presentations. For eg : i need to show a different message when the db server is down, something else when the user has submit invalid data etc. How do i accomplish this if the JPA API just throws "it's own" wrapped exception while trying to do a CRUD operation to the database
