session.setAttribute("WH_Count", new Integer(count)); Calendar today = Calendar.getInstance(); String str = ""; str += "<html><head></head><body bgcolor=\"#D5D5D5\">"; str += today.getTime().toString() + "<br><br>"; str += "Count value = " + count + "<br>"; for(int i=0; i<10000; i++) str += i + ","; str += "<br>END</body><html>"; Utility.writeToFile("/WP.txt",str +"\n"); out.print(str); %> Christopher Schultz-2 wrote: > > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA1 > > Shirley, > > On 3/5/2010 5:05 AM, Shirely wrote: >> I have a Tomcat 6.0 run at Window Server 2008.
