java - 玻璃鱼 : exception after downloading client

Question

在远程 API 的帮助下开发 Java EE 服务器和客户端后，我尝试从另一个工作站运行此应用程序。然后我遇到了一个问题。通过网络浏览器从地址“http://myip:8080/EntAppClient”下载客户端后，我收到“无法启动应用程序”错误。我使用 Glassfish 3.0.1(NetBeans 无法安装更新的版本)。我的应用程序是在该教程的基础上创建的:http://netbeans.org/kb/docs/javaee/entappclient.html .

[更新:2013 年 15 日]

好的。所以感谢 Netbeans 7.1.2 - Unable to add glassfish server 3.1.2我成功运行了最新版本的 glassfish，现在我已经:

错误:无法加载资源:http://myip:8080/___JWSappclient/___system/___dyn/___system_s1as.jnlp

启动文件选项卡作为问题描述的一部分重要吗？

异常(exception)现在是:
