LAB-5542: Project Jersey: Building RESTful Web Services in Java

Last Updated: May 20th, 2009

Project Jersey is the reference implementation of JAX-RS (JSR-311) - Java API for building RESTful Web Services. This API makes RESTful Web Services development with Java and some other VM-based languages very easy and straightforward. Besides the features defined by the standards, Jersey defines additional set of API's that make the developers' life even easier.

In this lab, we will start from basics - showing how to build a Hello World type of application and then show some more advanced features of JAX-RS and Jersey such as support for various media types, basic error handling, MVC support and client-side API's.

Notations Used in This Documentation

• <lab_root> - directory into which lab zip file is unzipped
  • This document uses <lab_root> to denote the directory under which you have unzipped the lab zip file of this hands-on lab. The name of the lab zip file of this hands-on lab is 5542_restwebservice.zip.
  • Once you unzipped the lab zip file under <lab_root>, it will create a subdirectory called restwebservice. For example, under Solaris, if you have unzipped the lab zip file in the /home/user directory, it will create /home/user/restwebservice directory.
