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 only way you will now be able to get rid of it will be to kill it in Task Manager.
I don't know of any way around this. -----Original Message----- From: Stephen Clarke [mailto:[EMAIL PROTECTED]] Sent: Tuesday, January 22, 2002 10:42 AM To: tomcat Subject: Invoking a process on the server from a servlet 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() ); } What I'm getting is "invoked" in the browser window, but nothing visibly happens on my local machine( ie. server). I was hoping TaskInfo would start up. What I really want to do is open a file in notepad to tell me a visitor has just arrived. Am I barking up the wrong tree altogether. Should I generate an event and listen for it in another app running as a listener in the background, or is there just no way of invoking a process on localhost from a servlet. Thanks.
