From Bullant Software:
Bullant JRAP is a distributed GUI toolkit that lets you create thin-client applications that are deployed on a server but display their GUI on a networked device equipped with the Bullant Remote thin-client. Applications are built using Java and execute on a J2SE or J2EE server. By doing away with the browser, Bullant JRAP lets you write smaller and more-efficient apps and code that are not downloaded to the client. Bullant applications can run on Windows (including an Internet Explorer ActiveX Control), Palm OS, Pocket PC, and Java J2ME MIDP devices.
