simjava 1.2

simjava is a process based discrete event simulation package for Java, similar to Jades Sim++, with animation facilities.
A simjava simulation is a collection of entities each running in its own thread. These entities are connected together by ports and can communicate with each other by sending and receiving event objects.
A central system class will control all the threads, advance the simulation time, and deliver the events. The progress of the simulation is recorded through trace messages produced by the entities and saved in a file.

System requirements:
-

Enhancements
- Simulation occurs in lockstep with animation (no more reading trace and pause before animation starts)
- java beans for displaying + storing simulation results.
- JAR bundling of the simjava packages.
- More examples.
- A 2D Graph bean. (new since the alpha release)
- Improved simulation speed and support for native threads.
