我是 salesforce.com 平台的新手。我正在尝试执行给出的演示应用程序http://wiki.developerforce.com/page/Getting_Started_with_the_Force.com_REST_API。示例应用程序能够成功连接到 salesforce.com 并获取authentication token（在服务器日志中以粗体表示）。但是它无法到达登录页面https://login.salesforce.com。
我在代理服务器中工作，并在我的代码中配置了相同的配置。仍然 tomcat7 日志显示以下错误：

我配置代理设置的地方如下：
@WebServlet(name = "oauth", urlPatterns = { "/oauth/*", "/oauth" }, initParams = {
// clientId is 'Consumer Key' in the Remote Access UI
@WebInitParam(name = "clientId", value = "xxxx"),
// clientSecret is 'Consumer Secret' in the Remote Access UI
@WebInitParam(name = "clientSecret", value = "xxxxx"),
// This must be identical to 'Callback URL' in the Remote Access UI
@WebInitParam(name = "redirectUri", value = "https://localhost:8443/RestTest/oauth/_callback"),
@WebInitParam(name = "environment", value = "https://login.salesforce.com") })
public class OAuthServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
private static final String ACCESS_TOKEN = "ACCESS_TOKEN";

private String clientId = null;

private String redirectUri = null;
private String environment = null;

private String tokenUrl = null;
public void init() throws ServletException {

clientId = this.getInitParameter("clientId");
clientSecret = this.getInitParameter("clientSecret");
redirectUri = this.getInitParameter("redirectUri");

..... (rest of code)...
看来我的 java 代码无法连接到https://login.salesforce.com. 代理设置有没有问题。请帮我解决这个问题。
