我想知道为什么我会收到 ExceptionInInitializerError？
平台：
- 视窗;
- 玻璃鱼 3.1.2.2；
- 记事本++；
- Cometd java库；
- 码头图书馆；
- Javac 命令行；
我正在逐步建立一个cometd Web 应用程序。经过一些调试后，我意识到码头：HttpClient 类导致 ExceptionInInitializerError，有人可以告诉我这是为什么吗？
我所做的是我去评论代码行，直到我发现问题发生在哪里。
这是发生错误的 CometD_Client 类：
import java.util.*;
import java.net.URL;
import org.cometd.bayeux.*;
import org.cometd.bayeux.client.*;
import org.cometd.server.*;
import org.cometd.client.*;
import org.cometd.common.*;
import org.cometd.client.transport.*;
import org.eclipse.jetty.client.*;
import javax.swing.*;
public class CometD_Client
{
private String CurrentDate;
private String BayeuxServerURL$;
private HttpClient JettyHttpClient;
private Map<String, Object> TransportOptions;
private ClientTransport C_Transport;
private BayeuxClient C_Session;
private boolean HandIsShaken£ = false;
DayTimePanel Panel;
public CometD_Client(String BayeuxServerURL$, DayTimePanel Panel)
{
this.BayeuxServerURL$ = BayeuxServerURL$;
this.Panel = Panel;
// Create (and eventually set up) Jetty's HttpClient;
JettyHttpClient = new HttpClient();
/*
try
{
JettyHttpClient.start();
}
catch(Exception E) {}
/*
*/
// Prepare the transport;
//TransportOptions = new HashMap<String, Object>();
//ClientTransport C_Transport =
// LongPollingTransport.create(TransportOptions,
// JettyHttpClient );
//C_Session = new BayeuxClient(BayeuxServerURL$, C_Transport);
//C_Session.handshake();
//HandIsShaken£ =
// C_Session.waitFor(1000, BayeuxClient.State.CONNECTED);
if(HandIsShaken£)
{
// TO DO: Output that the handshake had succeed;
}
else
{
// TO DO: Output that the handshake had failed;
}
/*
C_Session.getChannel(Channel.META_HANDSHAKE).addListener
(
new ClientSessionChannel.MessageListener()
{
@Override
public void onMessage(ClientSessionChannel ThisMetaChanel,
Message msg)
{
// TO DO: Output msg to check it out;
C_Session.getChannel("/my/channel").subscribe
(
new ClientSessionChannel.MessageListener()
{
@Override
public void onMessage(ClientSessionChannel ThisChanel,
Message msg)
{
CurrentDate = msg.getJSON();
OutputCurrentDate();
}
}
);
}
}
);
/*
*/
}
public boolean GetIfHandIsShaken£()
{
return HandIsShaken£;
}
public String GetCurrentDate()
{
return CurrentDate;
}
/*
private void OutputCurrentDate()
{
Panel.GetJTF().setText(CurrentDate);
}
/*
*/
}

很抱歉寻求帮助来调试我的代码，但我已经尝试了好几天，但 ExceptionInInitializerError 仍然让我感到困惑。
