Question

我是Java ee的新手。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。第一次战争的教程似乎不在我的系统上运行。

我正在使用Netbeans 8.0，GlassFish 4.0和Windows 7操作系统。

1。我按照提供的说明操作，当我运行项目时我收到的第一条消息是添加了一个我没看到的服务器教程（firstcup-war）。

2。在添加glassfish服务器后，项目仍然没有部署在服务器，我从glassfish得到了这个警告和例外服务器：

2.1

Warning:   RAR5038:Unexpected exception while creating resource for pool DerbyPool. Exception : javax.resource.spi.ResourceAllocationException: Connection could not be allocated because: java.net.ConnectException : Error connecting to server localhost on port 1527 with message Connection refused: connect.
Warning:   RAR5117 : Failed to obtain/create connection from connection pool [ DerbyPool ].

Warning:   RAR5114 : Error allocating connection : [Error in allocating a connection. Cause: Connection could not be allocated because: java.net.ConnectException : Error connecting to server localhost on port 1527 with message Connection refused: connect.]

.....

and chain of other exception that caused the above execption.

2.2

Severe:   Exception while deploying the app [firstcup-war]
Severe:   Exception during lifecycle processing

.....

3。

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。

Answer 1

在教程中，maven只创建一个war文件。您必须使用glassfish控制台将其部署到glassfish服务器。

http://localhost:4848

此外，您还必须启动Java数据库。

asadmin start-database
