Intercepting exceptions in cocoon?
Hi all,
In version 1 of our application we returned exceptions wrapped in XML so
we could pass the XML down the pipeline and handle the messages
gracefully using XSLT. In version 2 of our application we do not return
our exceptions wrapped in XML (it is a requirement not to) therefore
when we throw an exception now, cocoon shows the horrible stack trace.
So may question is: is there a way to intercept the exception before
cocoon can report it? Can cocoon generators intercept exceptions so we
could write our own generator? Maybe there is a simple answer to this
already (apologies if so)?
Thx in advance
Ant

Yes, using <map:handle-errors>, have a look at the error handling samples at
