public void doPost(HttpServletRequest req,HttpServletResponse resp)
{
HttpSession session;
session=req.getSession(false);
username=req.getParameter("name");
chatarea=req.getParameter("category");
System.out.println("in put from html page "+chatarea);
System.out.println("name="+username+ind+chatarea);
if(cheackAddVector(username))
{
try
{
System.out.println("in the same name ");
resp.setContentType("text/html");
sout=resp.getOutputStream();
sout.println("<html>");
sout.println("SORRY THIS NAMED USER ALREADY LOGGED");
sout.println("</html>");
}
catch(IOException e22){System.out.println("EXCEption in init "+e22);}
}
else
{
System.out.println("in the servlet first:");
try
{
resp.setContentType("text/html");
resp.sendRedirect("http://202.71.128.48:8080/doc/en/servlets/project/a.html"
);
file://socket=null;
socket=sersocket.accept();
}
catch(Exception e){System.out.println("Exception in socket connection"+e);}
System.out.println("in the above of chatareacode:");
room_name=chatareacode(chatarea);
System.out.println("in the above addvectorelement:");
System.out.println("in the above out:");
String st=getname();
try
{
out=new DataOutputStream(socket.getOutputStream());
out.writeUTF("ouser_name");
out.writeUTF(username);
out.writeUTF("user_room");
out.writeUTF(room_name);
}
catch(IOException egg2r2){
try{
if(socket!=null)
socket.close();
System.out.println("in the EXCEPTION ist catch:");
}
catch(IOException egg22){
System.out.println("in the EXCEPTION 2nd catch:");
