I'm trying to open a url connection using url object by passing https protocol request.  But I'm getting "untrusted Server certificate chain" exception.  I've been to java forum I tried lot many things to get rid of this exception.  But I couldn't make it possible.

Environment is as follows:
Application Server is : WebLogic Application Server
normal java client.
Using JSSE on client side inorder to call https protocol from url.
I'm trying use url.openConnection from a java client to weblogic application server.
Any suggestions appriciated.

What certification did you install in server? Is it self signed certification or from root CA?

As u r connecting from client to server , u need to configure several things in particular order .
 
           First of all u have to check the sign certificate u have got for ur client application, whether it is included in ur server side list or not.
           Socondly , u should mention from where u have got the sign certificate , means u have signed it ur self or thru CA.B'coz several times ur own signed application gives this exception as it may not be listed in the server side list.
           so , the only thing u have to check is the validation of ur certi and on server side its configuration.
             if still u find some problem during configuration ,  u can easily find me at

I'm getting this exception on client side. Not on server side. I'm getting this initially when client sends first packet of data to server.

This is the scenario.
First server gets the request from client, server sends a certificate to client.  Client checks whether the certificate from server is a trusted one. That's when I'm getting this exception on client side.

Here is the sample code snippet
import java.net.*;
import java.io.*;

/*
 * This example illustrates using a URL to access resources
 * on a secure site.
 *
 * To use Sun's reference implementation of HTTPS protocol, Please set
 * the following Java system property:
 *
 *    java.protocol.handler.pkgs = com.sun.net.ssl.internal.www.protocol
 *
 * If you are running inside a firewall, please also set the following
 * Java system properties to the appropriate value:
 *
 *   https.proxyHost = <secure proxy server hostname>
 *   https.proxyPort = <secure proxy server port>
 *
 */

public class URLReader
{
    public static void main(String[] args)
    {
        try
        {
            URL verisign = new URL("https://192.168.0.15:7002/");
            BufferedReader in = new BufferedReader(
                        new InputStreamReader(
                        verisign.openStream()));

            String inputLine;

            while((inputLine = in.readLine()) != null)
                System.out.println(inputLine);
            in.close();
        }
        catch(Exception e)
        {
            e.printStackTrace();
        }    
    }
}
