This article explores how a Java3D object communicates with a Waba application on a PDA over a wireless TCP/IP socket. Waba, a Java-like programming environment for PDAs, allows control requests to be sent over a socket, facilitating property changes in Java3D objects. While Waba has pros like efficiency and performance, it also has cons such as weak GUI support and limited communication programming environment.

Introduction • Java3D Object communicates with Waba Application on PDA over Wireless TCP/IP socket • Waba provides Java-like programming environment to PDA Scientific Visualization
Architecture PDA Application send control request over socket Socket (over Wireless LAN) Server Get request and change the property of Java3D object Scientific Visualization
Waba • Waba programming, which specially designed for smaller devices, is strict-subset of Java Language. • Waba is created by Wabasoft and has no connection to Sun Microsystems. • Comparing to KVM from Sun, it has more reliability and larger developers group now. Scientific Visualization
Waba: Pros and Cons • Pros: • Efficiency: It is small enough to fit less powerful PDA • Performance: Waba shows better performance than KVM • Portable: Platform independent Scientific Visualization
Waba: Pros and Cons • Cons: • Weak support of GUI, Events, and Exception • No Thread • Limited Communication Programming Environment (Byte Buffer) Scientific Visualization
Future Study • The Framework: • Visualization module register to Java Framework/Broker and it waits Waba Clients requests • Make an API to set up the protocols between Controller and Object Broker, between Broker and Waba Client Scientific Visualization
