hi ;
i am developing beginers level chat room servlet. i have done all
the session tracking part and sending part of it.
i can make users to connect to same session . but i am having probe
in the reciving part and the format in which msg can be recived.
for example if user A send msg to user b the user B can not see the
msg until he /she post a msg to user A. I mean session isnt
refreshing it self when msg are send .
and secondly he or she can see only last msg rather then entire
conversational.
if any one can lead me to source where i can find example of
beginers level that would be great full. or suggestion about the
correction in existing code.i am pasting a source of mine i havent
formatted the HTML yet ..

public class Servlet1 extends HttpServlet {
String oipt;
//Initialize global variables
public void init(ServletConfig config) throws ServletException {
super.init(config);
}
//Process the HTTP Post request
public void doPost(HttpServletRequest request, HttpServletResponse
response) throws ServletException, IOException {
response.setContentType("text/html");
PrintWriter out = new PrintWriter (response.getOutputStream());
String s=request.getParameter("a");
HttpSession se=request.getSession(true);
Integer c=(Integer)se.getValue("c");
c= new Integer(1521);
se.putValue("c",c);
String ipt =request.getParameter("a");
out.println("<html>");
out.println("<head><title>Servlet1</title></head>");
out.println(se.getValue("c").toString());
out.println("<body>");
out.print("<FORM
action=http://localhost:8080/servlet/untitled2.Servlet1
method=POST>");
out.println(oipt);
out.println(ipt);
oipt=ipt ;
out.println("<input type=text name=a>");
out.print("<input type=submit value=Submit><input type=reset
value=Reset></form>");
out.println("</body></html>");
out.close();
