Exception management in multi tier web apps

[MrNorth]

I guess no one likes exceptionmanagement eh
Come on, any architects here?

Generally, data layers should swallow errors, log them, and then rethrow them.

An error related to a data error that involves a custom object, like Registrant ie, should throw an InvalidRegistrant error (custom errors).

On the business side, again, custom objects should have their own custom exceptions.

Hi MrNorth,

I only handle the errors at each level, logging them, and then re-throwing them if necessary.
I have a question regarding the 'multi-tier' approach we use here:

Any input would be much appreciated

Many thanks
