Join Alex Theedom for an in-depth discussion in this video Solution: Add exception handlers, part of Java EE: RESTful Service with JAX-RS 2.0.
(digital music)…- [Narrator] So how did you get along with this challenge?…Your challenge was to add error handlers where appropriate.…Now your solution might differ slightly from mine.…So I'm just going to show you what I did.…Here in the older class, I decided I wanted to throw…an AuthorIDNotRecognizedException,…if an ID was passed into the getAuthor method…that was not recognized.…So what I had to do was to create…an AuthorIDNotRecognizedException,…and here in the getAuthor method,…all I've had to do is throw that exception,…and also what I need to do is…to create an exception manager.…
So I'll open up the Exception Manager…and show you what that looks like.…So here in the Exception Manager,…all I've done is to create…an AuthorIDNotRecognizedExceptionManager…and implement the Exception Manager interface.…And I've passed into that the exception…that I want it to handle.…I've implemented the method to response,…and within that method, all I'm doing is…I'm responding back to the client…with a NO_CONTENT response.…
