Java System commands

[mikedaruke]

I have a little mini application I am running.

When I click on an option can have it run a system command?

I want it to run a perl script.

So some how it has to go to the directory where the perl script is execute the perl script

Thanks in advance.

I'm not used to perl, but let's assume you call a perl script that way:

/usr/bin/perl /path/to/perlscript.pl

than you would call it from java like this:

String cmd ="/usr/bin/perl /path/to/perlscript.pl";
Runtime.getRuntime ().exec (cmd);

Most problems working with Runtime.exec are explained here:
