"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

The @Produces annotation is used to specify the MIME media types or representations a resource can produce and send back to the client. If @Produces is applied at the class level, all the methods in a resource can produce the specified MIME types by default. If applied at the method level, the annotation overrides any @Produces annotations applied at the class level.

If no methods in a resource are able to produce the MIME type in a client request, the JAX-RS runtime sends back an HTTP “406 Not Acceptable” error.

The value of @Produces is an array of String of MIME types. For example:
@Produces({"image/jpeg,image/png"})
The @Consumes annotation is used to specify which MIME media types of representations a resource can accept, or consume, from the client. If @Consumes is applied at the class level, all the response methods accept the specified MIME types by default. If applied at the method level, @Consumes overrides any @Consumes annotations applied at the class level.
@Produces is to the client
@Consumes  is from the client
