Can you describe your real problem ?

What is app about and what server should do and what client should do?

Have you written that servlet?

Do you know how to use servlet container?

Got it.I have a servlet which runs under Tomact.
What I am looking is write a standalone program to call the servlet.

Looks like I got the solution and is working...

public static void main(String[] args) {

try {
System.out.println("Connecting to Servlet");

URL url = new URL("http://localhost/servlet/YourservletServlet");

URLConnection conn = url.openConnection();
conn.setDoOutput(true);

BufferedWriter out =
new BufferedWriter( new OutputStreamWriter( conn.getOutputStream() ) );
out.write("username=name\r\n");
out.flush();
out.close();
BufferedReader in =
new BufferedReader( new InputStreamReader( conn.getInputStream() ) );

String response;
while ( (response = in.readLine()) != null ) {
System.out.println( response );
}
in.close();
}
catch ( MalformedURLException ex ) {
System.out.println("########"+ex);
ex.printStackTrace();
}
catch ( IOException ex ) {
System.out.println("@@@@@@@@@@@@@@"+ex);
ex.printStackTrace();
}catch(Exception e){
System.out.println("$$$$$$$$$$$$$$"+e);
e.printStackTrace();
}
}
