Well, if you want to be portable across platforms, you should write as much code in Java as possible and not rely on native scripts (I'm sure your script is more complex than this 'echo' example ;-) ).
Having said that, you can use the java.lang.Runtime class and in particular its various exec() methods.
Try something like this:
Process p;
try {
    p = Runtime.getRuntime().exec("myscript.sh");
} catch (IOException ioe) {
}You can then "interact" with the spawned process with the Process object returned by the exec method.
Note you need to have the appropriate security rights.
For more details, look at the API documentation here:
