異常與服務器

我的代碼連接XMPP聊天應用程序是異常與服務器

try { 
ConnectionConfiguration connConfig = new ConnectionConfiguration(hostname, portno, ""); 
       conn = new XMPPConnection(connConfig); 
       conn.connect(); 
       } 
      catch (XMPPException e) 
      { 
       throw new ProtocolException(e.toString()); 
      }

如何解決這個問題呢？

的拋出異常如果

InvocationTargetException - if the underlying method throws an exception.

因此，如果該方法，已經被調用與反射API，將拋出異常（例如運行時異常），反射API將包裹異常入一個InvocationTargetException。
