Developing Web Services using GT4

Please note that due to the current funding situation, the NGS no longer supports a Web Service interface to its resources. We have kept this tutorial online in case it is of use for users of other Grids.

In this hands-on session, we're going to build a Twitter-like web service using Globus Toolkit 4. Let's call it gTwitter.

If you don't know how Twitter works, here is a brief introduction. Twitter is a microblogging service. Users registered on Twitter can post a short message of no more than 140 characters long to their own home pages like blogging. Twitter users can follow others to see their postings as well.

Prerequisites

You need some basic knowledge about Java, XML, SQL, and required tools like Ant and database system Derby. However, you do not need to be an expert of these. And you're encouraged to make a group of members having different skills and work together.
