Information and Download 
Easy Java Simulations (Ejs) is a software tool designed for the creation of computer simulations.
It is designed for sicence teacher (not for professional programmer)
What user need to do is supply information about science model (define variable, provide initial condition- initial value for variables , giving evolution condition -how variable change with time or constrains between variables) , Ejs will create java applet/ html page for your simulation.
Please check out EJS wiki download for latest version
