I have the following code in my servlet, where 'out' is the
HttpServletResponse object.
Runtime t = Runtime.getRuntime();
try {
Process proc = t.exec( c:\\TaskInfo.exe );
out.write( invoked );
} catch ( java.io.IOException ioe ) {
out.write( ioe.toString() );
}

The problem is due to NT (or 2000) not allowing the Tomcat service to
interact with the desktop. If you bring up Task Manager, you will probably
see your invoked process running, but it can't create window. In fact, the
