I talk to many developers who want to install WebSphere Application Server for development, but every license is tracked and installed by their operations team on some remote server. Working with the operations team and (gasp) purchasing would take more time than the time to write the application they wanted to write. So they go off and download some other runtime and later port the application back to WebSphere Application Server or abandon the project altogether.
This won't be the story after today. Go here to download a no-charge copy of WebSphere Application Server for your development needs.
From the download page:
Download WebSphere Application Server for Developers, a no-charge offering that satisfies the need for a no-cost WebSphere Application Server development runtime for projects that don't warrant the expense of a priced and supported runtime on the developer desktop. Reduce testing effort and develop with confidence using a runtime environment that is identical to the production runtime environment your applications will eventually run on.
