How to run a java program in a separate process using GUI button?

[misbah.mubarak]

I want to run a java program using a button on the GUI. I have used
the following code
try{
System.out.println("Inside execution");
Runtime.getRuntime().exec("cmd.exe");
System.out.println(command);
process= new ProcessBuilder(command);
process.start();
}
catch(Exception except)
{
except.printStackTrace();
}
The purpose is to launch a separate execution window a part from the
cmd.exe thats open through the GUI. When I did this using process
builder,the output would come but not in a separate execution window.
Moreover, the output was not complete and the println statements were
not getting displayed.

Please, post your complete code. What about command and process
variables?

You could use System.err to get the println statements displayed. No?

I think I understood your problem now. Would you like "redirect" the
output stream of external process?
