Hi Alex,
Sorry for a delay, I've finally tried to get more optimized hierarchies
supported but I'm not sure we can get a handle on this top-level
parameter, here is the test code:
private static class RuntimeExceptionMapper1
extends AbstractTestExceptionMapper<RuntimeException> {
}
private static class RuntimeExceptionMapper2
extends AbstractTestExceptionMapper<WebApplicationException> {
}
private static class AbstractTestExceptionMapper<T extends
RuntimeException>
implements ExceptionMapper<T> {
@Override
public Response toResponse(T arg0) {
// TODO Auto-generated method stub
return null;
}
}
ProviderFactory would get a list of generic interfaces and the bounds
from then and the best we can get to is 'RuntimeException' which is
obtained from "<T extends RuntimeException>".
Any idea on how to get to say "WebApplicationException" which is visible
in the code at least in
"AbstractTestExceptionMapper<WebApplicationException>".
I'm wondering if it is even available at the runtime,
Sergey

What is happening is that when FooException is thrown in the

I believe I have found the solution. Despite the child exception
mappers specifying a generic type required by the parent (abstract)
exception mapper (which implements ExceptionMapper), each child class
also needs to include a "implements ExceptionMapper<T>" declaration,
to prevent CXF from bubbling up to the base interface implementation
declaration and using that class's generic type.
Thus, my exception mapper hierarchy is now:
(abstract) BaseRuntimeExceptionMapper<T extends BaseRuntimeException>
FooExceptionMapper extends BaseRuntimeExceptionMapper<FooException>
implements ExceptionMapper<FooException>
BarExceptionMapper extends
BaseRuntimeExceptionMapper<BarException>implements
ExceptionMapper<BarException>
This seems a little repetitive, but I think it makes sense given the
route that CXF seems to be using to determine the exception type.
Hope this helps someone else!
Alex
