Error while connecting to facebook server through the proxy - java

I am having problems connecting to gtalk/facebook server from behind a proxy .In my loginservlet under doPost I specify the proxy settings before making a connection with the servers.The code is as follows:
package web;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.jivesoftware.smack.XMPPConnection;
import org.jivesoftware.smack.XMPPException;
import org.jivesoftware.smack.proxy.ProxyInfo;
import dao.MySASLDigestMD5Mechanism;
public class LoginFacebookServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
public LoginFacebookServlet() {
super();
}
XMPPConnection connection;
/**
* #see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
*/
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
String userName = request.getParameter("usrnm_fb");
String password = request.getParameter("password_fb");
response.setContentType("text/html");
PrintWriter pw=response.getWriter();
SASLAuthentication.registerSASLMechanism("DIGEST-MD5", MySASLDigestMD5Mechanism.class);
//SASLAuthentication.supportSASLMechanism("DIGEST-MD5", 0);
ProxyInfo proxyInfo = new ProxyInfo(ProxyInfo.ProxyType.HTTP,"proxy.xxx.com" "talk.google.com", port, "username", "password");
ConnectionConfiguration config = new ConnectionConfiguration("chat.facebook.com",5222,proxyInfo);
connection = new XMPPConnection(config);
config.setSASLAuthenticationEnabled(true);
try {
connection.connect();
} catch (XMPPException e) {
e.printStackTrace();
}
try {
connection.login(userName, password);
} catch (XMPPException e) {
e.printStackTrace();
}
System.out.println(connection.isAuthenticated());
// System.out.println("Welcome!!you are now connected to facebook");
}
}
When I run the application it still gives me 500 status error.Following is the stack trace
XMPPError connecting to chat.facebook.com:5222.: remote-server-error(502) XMPPError connecting to chat.facebook.com:5222.

I checked to see if any thing more was there to add for by passing proxy but am unable to understand as to where am I going wrong?
Thanks:)

XMPP != HTTP so there's no reason to expect that an HTTP proxy will be used by an XMPP client. However, it seems like Smack has added HTTP proxy support (in addition to SOCKS4 and SOCKS5 proxy support they had earlier). The ConnectionConfiguration can accept a ProxyInfo parameter.
As far as I can tell from the JavaDocs, this is what you need to do:
ProxyInfo proxyInfo = new ProxyInfo(ProxyInfo.ProxyType.HTTP, "proxy.xxx.com", 8080, "username", "password")
ConnectionConfiguration config = new ConnectionConfiguration("facebook.com", 5222, proxyInfo);
XMPPConnection conn = new XMPPConnection(config);
conn.connect();
Also, for future questions, please note
Although your question is tagged 'Smack' you posted no Smack specific code. The lines showing use of the URLConnection are pointless since that's not where your connection is failing.
Your question title indicates Google Talk, however everything else refers to Facebook. This is confusing and unclear questions or code that is NOT what you're actually working with will most likely lead to frustration for you and other members. As far as possible, you should post an SSCCE.

javax.servlet.ServletException: Class com.mq.sample.Hello is not a Servlet

I am trying to create simple login application.I have created one login page and one servlet but it is giving the ServletException
here is my sample code.
public class Hello extends HttpServlet{
#Override
public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException,IOException{
try{
response.setContentType("text/html");
PrintWriter out = response.getWriter();
String username=request.getParameter("username");
String password=request.getParameter("password");
out.println("hello");
if(username.equals("xyz")&&password.equals("password"))
{
HttpSession session=request.getSession();
session.setAttribute("uname",username);
RequestDispatcher rd=request.getRequestDispatcher("/Home.jsp");
rd.forward(request, response);
}
else
{
RequestDispatcher rd=request.getRequestDispatcher("/login.html");
out.println("<h4>Plz provide correct Username or password</h4>");
rd.include(request,response);
}
out.close();
}catch(Exception e){System.out.println(e);}
}
this code is giving the following Exception:
I am not getting why this.

You are getting error from Tomcat, refer to this link. So the thing is that you have servlet jar conflict in your classpath.
Remove javax.servlet-api.jar from classpath and do this.

Please tell me why this is happening.
That looks like a deployment issue - you probably just need the jasypt jar file in the lib directory for your webapp.

Implementing auth in web application

I want to use auth application for my web application to skip the registration process for user . I am using http://code.google.com/p/socialauth/ java library for implementation of auth.I am facing following problem
1.I have created the secret key with those auth provider like twitter. but i am having problem while running this app locally on my system as i give the address of my site required while generating the secret key.
2.I am not able to configure my host file so that it take the properties my the address which i gave while generating the secret key .
Here is the piece of code executing .
package com.auth.actions;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.apache.struts.action.Action;

import org.apache.struts.util.RequestUtils;
import org.brickred.socialauth.AuthProvider;
import org.brickred.socialauth.AuthProviderFactory;
import com.auth.form.AuthForm;
public class SocialAuthenticationAction extends Action {
final Log LOG = LogFactory.getLog(SocialAuthenticationAction.class);
#Override
public ActionForward execute(final ActionMapping mapping,
final ActionForm form, final HttpServletRequest request,
final HttpServletResponse response) throws Exception {
AuthForm authForm = (AuthForm) form;
String id = authForm.getId();
System.out.println("in authentieavtaonsdfsaf");
AuthProvider provider = AuthProviderFactory.getInstance(id);
String returnToUrl = RequestUtils.absoluteURL(request,"/socialAuthSuccessAction.do").toString();
authForm.setProvider(provider);
String url = provider.getLoginRedirectURL(returnToUrl);
LOG.info("Redirecting to: " + url);
if (url != null) {
ActionForward fwd = new ActionForward("openAuthUrl", url, true);
return fwd;
}
return mapping.findForward("failure");
}
}
Here at line number 23 it is thowing null pointer exception saying that provider is coming as null

AuthProvider provider = AuthProviderFactory.getInstance(id); is throwing a NPE, because a property-file should be loaded, which does not exist:
java.util.Properties.load(Unknown Source)
But I don't know, which one is missing. I am sure you have to include some kind of property-file.
edit
http://code.google.com/p/socialauth/wiki/StrutsSample
In this sample-project you ca see a file called oauth_consumer.properties
May be that property-file is missing?

NPE when POSTing Binary data to RESTEasy Service

Please note: This is a cross post from with the resteasy developers mailing list.
The Binary data was a red herring, I had the annotations in the wrong place, they should have been on the setter methods rather than the member variable.
public class MyForm
{
private byte[] block;
public MyForm(){}
public byte[] getBlock()
{
return block;
}
#FormParam("block")
#PartType("application/octet-stream")
public void setBlock(final byte[] block)
{
this.block = block;
}
}
I am not familiar with RestEasy, but your stack suggests that you do not have an instance of MyForm... Since it looks like this is based on reflection, I would suggest you look over your configuration (maybe some type of dependency injection?) to ensure that the object is being instantiated.
