How to invoke a Web project JSP or servlet in Java code

Sometimes it is necessary to invoke a JSP or servlet for a Web project, but executing the internal code does not open the JSP, for example, to clear a cache in a Web project in a piece of Java code, so you can put the erased cached code in a servlet of that Web project. Just execute the following code:

New URL ("Http://192.168.2.123:8080/sace/ClearCache"); Url.openstream ();

OpenStream () executes one URL request at a time, where url.openstream () = Url.openconnection (). getInputStream ();

Where ClearCache is a servlet in a Web project

InputStream is =new BufferedReader (newnull;  while NULL ) {    System.out.println (line);  }

The above code can take out the contents of the returned page
