RESTfu­­l Jav­a­ wit­h ­JAX­-­­RS 2.­0­ (Second Edition)

Wrapping Up

In this chapter, you learned that JAX-RS has default response codes for both success and error conditions. For more complex responses, your JAX-RS resource methods can return objects. JAX-RS has a few exception utilities. You can throw instances of or let the underlying servlet container handle the exception. Or, you can write an ExceptionMapper that can map a particular exception to an HTTP response. Chapter 22 walks you through some sample code that you can use to test-drive many of the concepts and APIs introduced in this chapter.
