Execute jar in program code

[Cyrus Lan]

I have a jar file, without source code, say abc.jar.
I have set it in the CLASSPATH
The main execute class in abc.jar is a.class.
In the command prompt, I can execute the program by
issuing "java a < someIOfile"

But I would be like to embed it in my program.
Can I create a "dynamic" instance from it?

Sure. Just call "a.main(params) ". It's a static method no different
from any other Java method, so you can call it as you desire from within
any Java code.
