在远程 API 的帮助下开发了 Java EE 服务器和客户端后，我尝试从另一个工作站运行这个应用程序。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。

行。所以感谢Netbeans 7.1.2 - 无法添加 glassfish 服务器 3.1.2我设法运行了最新版本的 glassfish，现在我有了：

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

作为问题描述的一部分，启动文件选项卡是否重要？

现在例外是：
