I ran through the example code from https://developer.salesforce.com/docs/atlas.en-us.api.meta/api/sforce_api_quickstart_steps.htm but all I get is a timeout error during the first login stage. I've created a developer login and generated the wsdl, and then the .jar. The program compiles. I even tried it with the following example I found elsewhere:

import com.sforce.soap.enterprise.Connector;
import com.sforce.soap.enterprise.EnterpriseConnection;
import com.sforce.ws.ConnectionException;
import com.sforce.ws.ConnectorConfig;
 
public class Main {
    static final String USERNAME = "username redacted";
    static final String PASSWORD = "password redacted";
    static final String AUTH = "https://login.salesforce.com/services/Soap/c/37.0/0DF58000000L2Vm";
    static EnterpriseConnection connection;
 
    public static void main(String[] args) {
        ConnectorConfig config = new ConnectorConfig();
        config.setUsername(USERNAME);
        config.setPassword(PASSWORD);
        config.setAuthEndpoint(AUTH);
        try {
            connection = Connector.newConnection(config);
            // display some current settings
            System.out.println("Auth EndPoint:"+config.getAuthEndpoint());
            System.out.println("Service EndPoint:"+config.getServiceEndpoint());
            System.out.println("Username: "+config.getUsername());
            System.out.println("SessionId: "+config.getSessionId());
        } catch (ConnectionException e1) {
            e1.printStackTrace();
        }
   }
}

But when I run both hang for ages and then give a ConnectException: Connection Timed Out

I've checked using wireshark and with my system admin that its not the firewall: the DNS lookup is correctly resolving 'login.salesforce.com' and there are definetly packages going out. What else could I be doing wrong?

 

Hi,

I am getting started with the Streaming API but I haven't been able to subscribe to any Streaming Push Topic.
I have followed the steps suggested by the Trailhead tutorial: https://developer.salesforce.com/trailhead/api_basics/api_basics_streaming
When I click the Subscribe button, nothing happens. The channel section appears Connected/Disconnected randomly.

I have tried to debug the issue using my browser console, and the only message received when trying to subscribe is:

uncaught exception: Illegal state: already disconnected

The message persists either when the channel status is Connected/Disconnected.

The subscription has failed in any browser (Chrome, Firefox, IE).

Any hint? Thanks!!!!!!
