It is a command-line tool that you can use to shut down or restart a local or remote computer that is running Windows 2000 or Windows NT 4.0. If you want to schedule a computer to shut down and restart at a specific time, use Shutdown.exe in combination with the at command or Task Scheduler.

C:\Documents and Settings>shutdown /?
Usage: shutdown [-i | -l | -s | -r | -a] [-f] [-m \\computername] [-t xx] [-c "comment"] [-d up:xx:yy]

Examples :

• To shut down the local computer in two minutes and display a "The computer is shutting down" message, use the following line in a batch file or type it at a command prompt, and then press ENTER:

shutdown /l /t:120 "The computer is shutting down" /y /c

How to disable browser caching for a specific JSP?

It is possible to keep the browser from caching a JSP page response. The following hints added to the response header seem to prevent most modern browsers from pulling pages out of cache when the same URL is "hit":


response.setHeader( "Pragma", "no-cache" );
response.setHeader( "Cache-Control", "no-cache" );
response.setDateHeader( "Expires", 0 );


The same effect can be achieved by using meta tags in the HTML header:

meta http-equiv="Pragma" content="no-cache">
meta http-equiv="Cache-Control" content="no-cache">
meta http-equiv="Expires" content="Sat, 01 Dec 2001 00:00:00 GMT">


The Cache-Control header was added in HTTP 1.1, while the other two were also present in HTTP 1.0.

// converting the Values's to String Array
strArray = (String[])(hMap.values().toArray(new String[0]));
System.out.println( strArray[0] + strArray[1]);

// converting the Key's to String Array
strArray = (String[])(hMap.keySet().toArray(new String[0]));
System.out.println( strArray[0] + strArray[1]);
}
