Class CatchExceptionMapper

java.lang.Object
  org.jboss.seam.rest.exceptions.SeamExceptionMapper
      org.jboss.seam.rest.exceptions.integration.CatchExceptionMapper

All Implemented Interfaces:

ExceptionMapper<Throwable>

@ApplicationScoped
@HandlesExceptions
@Specializes
public class CatchExceptionMapper
extends SeamExceptionMapper
implements ExceptionMapper<Throwable>

A JAX-RS ExceptionMapper implementation that maps all exceptions (i.e., Throwable) raised during a JAX-RS request to the Seam Catch exception handling bus.

Exceptions are send to Seam Catch by firing an event of type ExceptionToCatch to the CDI event bus. The event payload contains the exception and the qualifier @RestRequest. The qualifier allows handlers that deal specifically with REST requests to be selected.
