Some simpified code for creating an external process, and getting a stream
to its output.
Process p = Runtime.getRuntime().exec("c:\doit.exe");
InputStrem is = p.getInputStream();
Note:
1. The behaviour of Runtime.exec is somewhat platform-dependant so you want
to test thoroughly. (Also the servlet might not be allowed to create
external processes.)
2. Potential performance issue, as you are probably aware of. Creating
processes is expensive in most op systems, and context-switching is a
problem in NT. (Thats why we do Servlets instead of CGI. :)
