Glassfish：下载客户端后出现异常

Question

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）。我的应用是在该教程的基础上创建的：http://netbeans.org/kb/docs/javaee/entappclient.html。

[更新：15 I 2013]

好的。多亏了Netbeans 7.1.2 - Unable to add glassfish server 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

启动文件标签作为问题描述的一部分重要吗？

例外现在是：

com.sun.deploy.net.FailedDownloadException: Unable to load resource: http://myip:8080/___JWSappclient/___system/___dyn/___system_s1as.jnlp
