Store an XMPPConnection (Smack chat library obj) in a session

Question

Hello all,
I am attempting to develop a web based chat client (I have already seen jwchat and some others) using the open source Smack libraries.
I want a way to maintain the XMPPConnection object in the session.
Below is some code I am using:
//here is a method within my class file that will return a XMPPConnection object (this is a connection to a XMPP chat server) it also attaches a listener to the connection object.
//Called when the user submits his/her credentials..
//This works fine as I can see a connection in the chat server admin page.
   public XMPPConnection getConnx(String user, String pwd) throws XMPPException
       XMPPConnection connx = new XMPPConnection(HOST,PORT);
       PacketTypeFilter filter = new PacketTypeFilter(Message.class);
       connx.addPacketListener(messageListener,filter);
       connx.login(user,pwd);
       System.out.println("getConnx called");
       return connx;
//This is a method that creates the chat. I call this from  a jsp using Ajax to a servlet see below:
   public void setChat(String msg,String user,Object connex) throws XMPPException
       XMPPConnection connx = (XMPPConnection) connex;
       Chat chat = connx.createChat(user+"@asterisk1.local");
       Message message = chat.createMessage();
       message.setBody(msg);
       chat.sendMessage(message);
       System.out.println("ORIGIINATE from this conx="+connx.getConnectionID());
//below is the ajax call to SendChat.java (servlet)
    var file = "SendChat?user="+User+"&message="+Message+"&connx="+<%=session.getAttribute("connection")%>;
//then SendChat calls the  above setChat method like so:
            String message = request.getParameter("message");
            String user = request.getParameter("user");
            XMPPConnection connx = (XMPPConnection) request.getAttribute("connection");
           webconnect.setChat(message,user,connx);I am getting a null pointer exception that points to the setChat method (the following line):
Chat chat = connx.createChat(user+"@asterisk1.local");I am thinking that I cannot store the connection in the session?
Can I ?
If so does it look like I am storing and passing the connection properly?
Here is one more line of code from the jsp that actually creates the session:
session.setAttribute("connection",chatt.getConnx(request.getParameter("id"),request.getParameter("pwd")));TIA!

Dear Gforty
I'm sending this message after checking part of your XMPP sources using Smack chat library at Java forum.
I'm planning to a make web-based chatting program and I would like to get some idea from your sources if you don't mind.
Could you send me the whole sources to the following e-mail address, please?
I hope your reply, thank you
