[Djamel Djemaoun]

Hello,
My problem is the following:
I want to run (execute) from java application an external program, for example batch file or perl file.
How to do it?
Thanks a lot.

Some sample code ... sufficient to get you started I hope

Runtime rt=Runtime.getRuntime();
String sExec = "rm -r "+nextFile;
Process ps=rt.exec(sExec);
ps.waitFor();
if(ps.exitValue() != 0){
    System.out.println("File deletion could not be done.Process exited with a value "+ps.exitValue());
}
