Wait guys....
I thought you don't need anything other than JDK 6 to implement JAX-WS. In fact, i can build a JAX-WS service and run it just by using JDK 6.
To generate client artifacts, you are good with JDK 6 too.
Only for JAX-RS you need to download its implementation (Jersey is the one i have been using from a year or so)
Well, i understand that for production ready systems you will need an application/web container but just for hands on and to understand/learn web services, i dont think we need anything special other than JDK.
Please validate as i might be wrong...
