If you are a J2EE developer, you should be interested in this. The IBM WebSphere Application Server runtime is being made available to developers at no cost. Developers can use the development runtime test environment that is identical to the WebSphere Application Server (WAS) production runtime environment on their desktop at no charge for development and testing. And this is the recent version 7 of WAS. If you are considering a J2EE server, this is a great way to try out WAS.
