How to add headers to HTTP response within ClientErrorException?

Question

I have a custom ClientErrorException and I want to add some specific headers to the response when this exception is thrown.

For example, I can specify status of the response in the constructor:

public ClientErrorException(String message, Response.Status status) {
...
}

But how to specify headers? What the proper way to do that?

Answer 1

You can use an ExceptionMapper for jax-rs to return a custom response when an exception is thrown.

There is a nice example in here
