Restarting Tomcat service through servlet which is hosted in the same Tomcat -

I would like to restart the Tinker service on Windows XP, I have created a sublet that calls a batch file

  throws public Zero doGet (HttpServletRequest req, HttpServletResponse Res) ServletException, IOException {Process p = Runtime.getRuntime (). Exec ("c: \ restart_tomcat.bat"); }   
 my  restart_tomcat.bat   
  net stop "tomcat 6" net start "tomack 6"  < / Pre> 
 The request for servlet URL stops the Tomcat server, although it has not started.   
 
 RuntimeGetRight (). Exec ("cmd.exe / c start c: \ restart_tomcat.bat");
