UltraLightClient (ULC) is a Java library for web user interface development, bridging the gap between Java Swing and a server-side architecture. UltraLightClient allows Java developers to develop mission-critical Enterprise Web 2.0 applications with a rich and responsive user interface using proven Java technology both on the client and on the server.

ULC Mobile is specially geared for Rich Internet Applications (RIAs) running on top of the Java Micro Edition (Java ME) platform. Using ULC Mobile, you can now develop Enterprise Web 2.0 applications with a desktop user experience that will run on both Java SE and Java ME clients. The new product offers the same API as UltraLightClient, which means that existing UltraLightClient applications can essentially be reused without code changes.
UltraLightClient's built-in optimizations such as lazy loading and caching also apply to ULC Mobile, which make it particularly suited for handheld devices with their limited memory and slower network connections. Large server-based applications will be accessible via rich UIs on mobile devices and PDAs. ULC Mobile requires CrE-ME to be installed on the handheld device.

UltraLightClient-based applications can be deployed in a J2EE container, as a portlet, or stand-alone without changing the code. On the client, a standard JRE from 1.4 upwards is all that is required. The new product, ULC Mobile, extends the deployment options to mobile devices that run with the Windows CE operating system.
