This work reports three phases of development of a Java-based distributed system for the implementation of computational intelligence techniques to solve practical engineering problems. The first design of the Java-based system is called Para Worker. It is a library of application program interface (APIs) to facilitate parallel computation. Next, a new system, termed Para Worker 2 aimed at improving ease of programming and performance. It also adds enhanced features of improved dynamic object reallocation, adaptive consistency protocols, and location transparency. However, neither of these systems addressed the fundamental issues of Java virtual machine (JVM) in distributed environment. The third phase of development of the Java-based system is a new form of distributed JVM in order to execute Java program efficiently. The new system is termed Java distributed platform (JavaDP).
