exception handling best practices

I am wondering if there is a recommended way to map exceptions with jax-rs/jersey. I have been playing around with all the different exceptions that extend WebApplicationException, I have in some cases just pushed runtime exceptions back to the framework, and I have also considered using the ExceptionMapper interface. I realize that I could extend WebApplicationException to create my own exceptions aswell, but is that wise?

- I would like to have the most consistent relationship between application exceptions/errors and HTTP codes.
- I would also like to guarantee that a human readable message and a stacktrace travel with all my errors back to the client. Yet it seems that this happens with certain types of exceptions but not with others.
-I would also like to spend the least amount of time/energy on maintaining all these different possible states.

Is there one approach that's better than others? I can't at first glance see one. Am I missing something? Does anyone have any recommendations experiences?
