Data Representations, Inc. has announced Simplicity for Palm OS Platform Version 3.0, generally available for delivery on February 9, 2004. Simplicity for Palm OS Platform Version 3.0 is a visual RAD tool for building robust J2ME/MIDP applications. By dragging and dropping visual parts, a developer can assemble user interfaces, images, threads, timers and network communications. Simplicity simplifies the process of building great J2ME applications that will run on palmOne devices, and many others using the Palm OS Platform.

Simplicity for Palm OS Platform version 3.0 includes palmOne's Java Toolkit, which enables J2ME/MIDP applications to run on all Tungsten handheld devices and Treo smartphones. Simplicity also includes the IBM WebSphere Micro Environment for palmOne handhelds which targets most handhelds with Palm OS 3.5 and higher. Simplicity's built in emulators can show the user exactly how their applications will look while coding during the visual designing process. The emulator includes skins for a wide range of Palm OS devices so the user can switch from device to device at any time. Simplicity also includes packaging features, which can handle all of the assembly and deployment requirements. It can produce JAR/JAD and PRC files with only a few mouse clicks, ready to install on an actual Palm OS based handheld.

Simplicity's Execution-On-The-Fly technology integrates every change to the application's code instantly into the running application. There is no need to recompile the application with every change. The application continues to run in the emulator, and each change occurs instantly. So even before compiling, a developer will know if what they designed is correct.

Other features include the Sourcerer's Apprentice, which is a code completion tool, and The Code Sourcerer, which is an automatic coding tool that can create large blocks of code by interviewing the user in plain English. These tools eliminate many possible errors, providing a guide to all possibilities.

Simplicity for Palm OS Platform version 3.0 can be extended to build end-to-end, network-aware mobile/enterprise applications when added to Data Representations' J2EE/J2ME tool, Simplicity for Mobile Servers. Using XML over HTTP, Simplicity for Mobile Servers makes it easy to collect data from JDBC data sources and legacy applications for building interactive, MIDlet to SERVlet, wireless applications.
