haven't done this in a while, but I think it's:
Code:
try {
  java.lang.Process process = java.lang.Runtime.getRuntime().exec("command args");
  int retCode = process.exitValue();
}
catch (Exception e) {  }

If the 'exitValue()' method doesn't work, you may need to use 'getOutputStream()' to get the return value which is piped to stdout.

hth,
dv
