I have wrote a processing program (A) in eclipse, and now I want to use another program to invoke A multiple times (sequentially) each with different arguments.

I looked up how to do it in Java, but it gives me NoClassDefFoundError for core/PApplet. I cannot figure out how to fix this. Does anyone know how to solve this?

Thanks for your help in advance!

Here is the code.

1. Runtime runTime = Runtime.getRuntime();
2. //external is the folder where I have my core.jar
3. //LowGame contains my main and it's in the control package, 2 is the command argument I want to pass in
4. Process  process = runTime.exec("java -classpath C:\\Users\\chang\\git\\Game\\external\\core.jar -classpath C:\\Users\\chang\\git\\Game\bin control.LowGame 2");        

Here is the error message I'm getting:
