[Resteasy-developers] Exception handling

[Christian B. <chr...@gm...>]

I'm trying to integrate exception handling with Seam, a few issues:

Resteasy doesn't implement the JAX RS exception handling nearest-type  
search: https://jira.jboss.org/jira/browse/RESTEASY-69 - so I can't  
write a generic ExceptionMapper<Exception> and delegate all of that to  
Seam.

The second issue is that Resteasy swallows exceptions (and worse, it  
writes ugly logs): https://jira.jboss.org/jira/browse/RESTEASY-105

Seam has an ExceptionFilter, we need it to destroy contexts, end  
transactions, and so on. That filter will not run if  
dispatcher.invoke() does not throw an exception.

I'm not sure how to best solve both issues. It's hard to implement a  
cleanup routine in Seam as a generic ExceptionMapper<Exception>, so  
I'd really like the regular ExceptionFilter to run. But that means  
that ExceptionMapper invocation has to occur outside of  
dispatcher.invoke().

Probably the best solution would be to implement ExceptionMapper  
handling in Resteasy as some kind of filter I could enable/disable/ 
extend.
