我是 Java ee 新手。我从 oracle java ee 页面获得了一个教程firstcup。我按照 Dukes-age 的教程进行操作，效果很好。 Firstcup-war 的教程似乎无法在我的系统上运行。
我使用的是 Netbeans 8.0、GlassFish 4.0 和 Windows 7 操作系统。
1. 我按照提供的说明进行操作，当我运行该项目时 我收到的第一条消息是添加一个我在网上没有看到的服务器 教程(firstcup-war)。
2. 添加 glassfish 服务器后，项目仍未部署 服务器和我收到来自 glassfish 的警告和异常 服务器:
2.1

在运行(firstcup-war)输出页面上，我在显示构建成功的日志后收到此消息:

请帮我解决这个问题。
最佳答案
在教程中，maven 仅创建一个 war 文件。您必须使用 glassfish 控制台将其部署到 glassfish 服务器。
http://localhost:4848
您还必须启动 Java 数据库。
asadmin start-database
