java - 当我将 标记放入 web.xml 时发生错误

Question

当尝试运行项目时，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:

这是我的 xml 文件:

当我放置 <resource-ref> 时出现问题在 web.xml 文件中。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 <resource-ref>标记项目部署成功，但数据不会出现在数据库中。可能是什么问题？

Answer 1

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

由于包错误，您会收到错误 - 否则 <resource-ref>很好。应该是

**javax**.sql.DataSource
