Question

我正在尝试从java类（在我的本地计算机上）连接到Salesforce。我使用了WSC-22.jar（webservice连接器）并在eclipse中使用了相同的库。我还将企业wsdl解析为jar并在eclipse中上传了库。我正在运行下面的错误输出的java类。

package wsc;

import com.sforce.soap.enterprise.Connector;
import com.sforce.soap.enterprise.DeleteResult;
import com.sforce.soap.enterprise.EnterpriseConnection;
import com.sforce.soap.enterprise.Error;
import com.sforce.soap.enterprise.QueryResult;
import com.sforce.soap.enterprise.SaveResult;
import com.sforce.soap.enterprise.sobject.Account;
import com.sforce.soap.enterprise.sobject.Contact;
import com.sforce.ws.ConnectionException;
import com.sforce.ws.ConnectorConfig;

public class main {

static final String USERNAME = "username";
static final String PASSWORD = "password + sec token";
static EnterpriseConnection connection;

public static void main(String[] args) {

ConnectorConfig config = new ConnectorConfig();
config.setUsername(USERNAME);
config.setPassword(PASSWORD);
//config.setTraceMessage(true);

try {

  connection = com.sforce.soap.enterprise.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());

  // run the different examples
  queryContacts();
  createAccounts();
  updateAccounts();
  deleteAccounts();


} catch (ConnectionException e1) {
    System.out.println("hello world");
    e1.printStackTrace();
}  

}
//somemore code----

错误消息： com.sforce.ws.ConnectionException：无法向

我无法弄清楚如何解决这个问题。正如错误消息“Falied to connect to http://login.salesforce.com./ ...”，我应该在Eclipse中启用某些设置吗？

Answer 1

你是代理人吗？

如果是这样，请在eclipse中启用代理设置 preferences general → network

Answer 2

...

  String proxyHost = getUserInput("Enter proxy host:");
  String proxyPort = getUserInput("Enter proxy port:");

  try {

...

     if(proxyHost!=null && !proxyHost.trim().equals("")){
      config.setProxy(proxyHost, Integer.valueOf(proxyPort));
     }

...

使用Web服务连接器从java访问salesforce
