Java 放置<；资源参考>；web.xml中的标记

尝试运行项目时，我在项目控制台上收到以下错误消息：

Error occurred during deployment: Exception while loading the app : java.lang.IllegalStateException: ContainerBase.addChild: start: org.apache.catalina.LifecycleException: java.lang.IllegalArgumentException: [java.sql.DataSource] is not an allowed property value type. Please see server.log for more details.
/media/work documents/UnderTest/NetbeansCurrent/ProjectSnippets/nbproject/build-impl.xml:724: The module has not been deployed.
See the server log for details.
BUILD FAILED (total time: 4 seconds)

这是服务器日志中显示的内容：

当我在web.xml文件中放置

时，就会出现问题。我已经连接到数据库了 并使用netbeans中的向导配置了数据源。如果我省略了

标记项目 已成功部署，但数据不会显示在数据库中。有什么问题吗

[java.sql.DataSource] is not an allowed property value type

您得到的错误是因为错误的包-否则

就可以了。应该是

**javax**.sql.DataSource
