Creating a Hello World RESTful web service with RAD and WebSphere Application Server using IBM JAX-RS

REST is the buzzword now. So its time to learn how to create a RESTful web service now. Here is my simple hello world tutorial on creating a RESTful web service using Rapid Application Developer and IBM JAX-RS. JAX-RS is a Java API for developing REST applications. JAX-RS 1.0 defines a server-side component API to build REST applications. This ia an implementation of the JAX-RS (JSR 311) specification.

All the REST implementations I have seen need a minimum Java 1.5 to run. All these implementations use annotations. So my code will not work on WebSphere Application Server 6 and below versions. The minimum required version is WebSphere Application Server 6.1. I have tested these examples only in WAS 7. You need to have Feature pack for Web 2.0 for WebSphere installed on your application server. So once you have your app server ready with Web 2.0 feature pack installed then you have pretty much everything to get started. Follow the below steps to create your first hello world RESTful web service with RAD and WAS 7. For my development purposes I was using RAD 7.5. But I am sure that the following steps will work even for other RAD version too.
