Support for Proxy with authentication

[GoogleCodeExporter]

What steps will reproduce the problem?
1.Generate jar from any  wsdl (I'm using the SFDC partners one)
2.Configure proxy parameters ( see code example below)
3. Call Connector.newConnection(config)

What is the expected output? What do you see instead?

Successful connection.
Instead I'm getting:
java.io.IOException: Unable to tunnel through proxy. Proxy returns "HTTP/1.1 
407 Proxy Authentication Required ( The ISA Server requires authorization to 
fulfill the request. Access to the Web Proxy filter is denied.  )"

What version of the product are you using? On what operating system?

I tested the issue on wsc-20.jar 

Please provide any additional information below.

I'm using the following code example:
***********************************************************************
package test.ws;

import com.sforce.soap.partner.*;
import com.sforce.soap.partner.sobject.*;
import com.sforce.ws.*;

public class simple {

    /**
     * @param args
     */

       public static void main(String[] args) {
                  ConnectorConfig config = new ConnectorConfig();
                  config.setUsername("myUser");
                  config.setPassword("mypass");
                  config.setProxy("10.1.1.15", 8080);
                  config.setProxyUsername("proxyUser");
                  config.setProxyPassword("ProxyPass");

                  PartnerConnection connection = null;
            try {
            connection = Connector.newConnection(config);

            } catch (ConnectionException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
                  SObject account = new SObject();
                  account.setType("Account");
                  account.setField("Name", "My Account1");
                  try {
                    connection.create(new SObject[]{account});
                } catch (ConnectionException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
       }

}
**************************************************************************

I'm using Microsoft ISA as my proxy configured to allow Basic auth.

While tracing the network traffic using wireshark I can see that the request is 
sent without auth header, the response is the 407 message and there is no 
following CONNECT with authentication being sent.

The following code seems to work:

When tracing the following code with wireshark, I can see that the first 
CONNECT message is sent with no authentication headers, the same 407 message is 
returning from the server and the client respopnd by CONNECT that has the 
authentication header (Proxy-authorization: Basic......)

One more issue that I forgot to mention is SSL tunneling, When using the proxy 
auth to connect to an HTTP URL everything work fine. Only when the URL points 
to an HTTPS I'm getting the error message.

This seems to work for me through a MS Proxy:

  ConnectorConfig partnerConfig = new ConnectorConfig();
  partnerConfig.setNtlmDomain("yourDomain");
  partnerConfig.setProxy("yourProxy", 80);
  partnerConfig.setProxyUsername("yourUsername");
  partnerConfig.setProxyPassword("yourPassword");
  partnerConfig.setAuthEndpoint("https://test.salesforce.com/services/Soap/u/21.0");
  partnerConfig.setConnectionTimeout(60 * 1000);
  partnerConnection = Connector.newConnection(partnerConfig);
  partnerConnection.describeGlobal().getSobjects()

I have the same problem with a non-MS proxy, and there have been no comments to 
this bug for over a year.

If the OP reads this, did you manage to solve it or found a work-around?

I'm using wsc-22-jdk-1-5.jar

Well...

If you can get the TestProxy2 example to work - then try the ConnectorConfig 
method:

public void setProxy(java.net.Proxy proxy) ;

You won't see this method in Salesforce's documentation.

If that doesn't work - check that machine running the Java code and ping 
www.cnn.com.

If it can't ping that machine then it's likely that a firewall policy is 
restricting access to the internet (and you have change the policy).

Hi,

The suggestion of Mclean Blades seems to do the trick. 
Thanks you very much.
