Re: RV: Runtime.exec()

2002-10-23 Thread Nigel . Byrnes 

If i understand your mail correctly, you are attempting to call/run an
external program. If so, then you need to get a pointer to the JVMs RunTime
environment and execute your command[s] in a new process. Note that you'll
need to setup the environment of the process. On a win32 platform, you'll
be looking to do something like this:

public void foo (String [] myCmds)
{
  try
  {
  // construct the the list of commands to be run based upon
  // - a set of cmds required to setup the environment of the process
  // - the user cmds in myCmds
String [] cmds = runTheseCmds (myCmds); // see javadoc/google for
more info
Runtime r = Runtime.getRuntime ();
Process p = r.exec (cmds);

  // here you can access stdout/stderr if you like


p.waitFor();
p.destroy();
  }
  catch (...)
  {
// see javadoc for the exceptions you need to catch
  }
}

The error you are seeing is relate to the way you create a process under 
win32. Read to avoid it.
