An amphibian called Eclipse RAP
Eclipse Rich Ajax Platform (RAP) is a slightly unusual framework. At first glance it looks like a competitor to Google Web Toolkit (my article about GWT), but a closer look tells a different story. RAP is meant to let you build Eclipse RCP applications that run in a browser as well as on the desktop. In that sense RAP is closer to a competitor to Adobe AIR.
I’ll spare you a lengthy description and point you to the demos, which show RAP at its best.

But why repeat what others have already written?
