Re: [Resteasy-developers] ExceptionMapper + exceptions from an EJB invocation

[Bill B. <bb...@re...>]

:(

You'll have to wrap your own provider.  I brought up this issue of 
wrapped exceptions in the EG and we're addressing it, although you'll 
still have to write a provider even with that solution...

However, I should probably have some good EJB integration and have a 
ExceptionMapper for EJBException...
