Hi…
I have login code in one servlet:LoginGtalkServlet…
XMPPConnection connection;
//@see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
String userName = request.getParameter("username");
String password = request.getParameter("password");
System.out.println(userName);
System.out.println(password);
//ProxyInfo proxyInfo = new
ConnectionConfiguration config = new ConnectionConfiguration("talk.google.com",5222,"gmail.com");
connection = new XMPPConnection(config);
config.setSASLAuthenticationEnabled(false);
try {
connection.connect();
} catch (XMPPException e) {
e.printStackTrace();
}
try {
connection.login(userName, password);
} catch (XMPPException e) {
e.printStackTrace();
}
boolean status=connection.isAuthenticated();
if(status==true)
{
System.out.println("Success");
response.sendRedirect("GetRoster");
}
And my GetRosterServlet has the code for retreving the roster list
protected void doPost(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
Roster roster = connection.getRoster();
Collection entries = roster.getEntries();
for (RosterEntry r : entries) {
String user = r.getUser();
String name = r.getName();
System.out.println(name + user);
}
roster.addRosterListener(new RosterListener() {
// Ignored events public void entriesAdded(Collection
// addresses) {}
public void entriesDeleted(Collection addresses) {
}
public void entriesUpdated(Collection<String> addresses) {
}
public void presenceChanged(Presence presence) {
System.out.println("Presence changed: " + presence.getFrom()
+ " " + presence);
}
@Override
public void entriesAdded(Collection<String> arg0) {
}
});
}
Now the isssue is my GetRosterServlet is not informed that I haved logged into Gtalk..i.e LoginGtalkServlet is not communicating with GetRosterServlet and hence connection.getRoster() is throwing Null pointer exception...
How do I let the roster servlet know that the user is logged into gtalk and hence get the friends list
I read about Session class in Smack API documentation.
I wanted to know if I can use HTTPSession get the logged info and pass or should I use Session class of smack for this??
An example would be good
