Help with exec

[Kamal Zamli]

Dear all

I'm trying to do compile + execute a java program from within
another java program... COnsider the following code:
.....
Process p1 = Runtime.getRuntime().exec("javac stub.java");
Process p2 = Runtime.getRuntime().exec("java stub");
.....

Using exec I manage to compile stub.java. However, I cant seem to be
able to run stub.class using exec... Any pointers ?

Thanks in advance

*Exactly* what happens instead?

Can you run it from a command shell, outside the program? Does it
generate any output?

1) You may want to wait a few seconds for it to finish compiling before
executing it.

2) You may want to specify the classpath when you execute the code.
