我只是按照在Netbeans页面上使用MySQL数据库创建简单Web应用程序的做法，遇到了一个错误

我无法使用glassfish运行我的初始步骤，所以安装tomcat，对于更简单的版本，它工作得很好。在添加MySQL数据库之后。正如文档所解释的，我已经定义了一个利用Netbeans glassfish功能的JDBC资源。然而，我在web.xml和glassfish-resources.xml下引用这些资源时，遇到了错误

我认为我应该以一种不同于任何教程所展示的方式来定义tomcat的jdbc源代码，但我是一个新手，没有太多的背景知识

如果你能给我一些想法或一份新手容易理解的参考文件，我将不胜感激

这是日志文件

试试看

而不是

type="javax.sql.ConnectionPoolDataSource"

另请参阅本文：

您是否在类路径中包含了

mysql连接器java-[version]-bin

？它应该放在

tomcat/lib文件夹中

。它位于ApacheTomcat 8.0.15\bin文件夹下，但我是在阅读了来自internet的帖子后下载的。版本是5.1.6.jar，但mysql版本是5.7，tomcat版本是8.0.15 netbeans版本是8。是否可能连接器的版本不正确？它应该放在

lib

文件夹中，而不是

bin

。在将jar复制到lib文件夹restart Tomcat之后，您可以在这里下载最新版本。它也在lib文件夹中，但我用最新的连接器文件替换了它。错误是一样的。我相信它与我的JDBC资源有关，因为我是从NETBeaS创建的，也许Tomcat不考虑它。你可以发布后ExtExt.xml吗？您是如何定义

jdbc/IFPNEW

资源的？实际上，我在这里发布之前已经做过了，但是我从头开始做了一次，以确保它不会有任何帮助。数据源无效：“java.sql.SQLException:无法创建PoolableConnectionFactory（未知数据库“connpool”）”确定更正数据库名称后，它实际上可以工作。谢谢你的帮助
