代码(省略了try...catch)：

WebConversation wc = new WebConversation();
WebResponse wr = wc.getResponse( "http://localhost:8080/ss/index.html" );
System.out.println( wr.getText() );
        }

输入结果：

   Rhino classes (js.jar) not found - Javascript disabled
   java.net.ConnectException: Connection refused: connect


怎么解决？
