HTTP 500 - 无法创建用于连接URL'''的类''的JDBC驱动程序'null'

我一直在寻找解决这个问题3天，阅读论坛...然后我决定寻求一些帮助。无情地说，你的帮助将不胜感激:-)HTTP 500 - 无法创建用于连接URL'''的类''的JDBC驱动程序'null'

我在Tomcat中创建了一个jndi资源在Tomcat中的context.xml实例在我的web应用程序工作正常，当我从eclipse启动服务器。当我从eclipse的“运行配置”启动web应用程序时，它不能正常工作：clean tomcat7：run。我的目标是将构建，部署，启动服务器委托给eclipse中的maven。

我已经把Tomcat_Home/lib中的mysql-connector-java-5.1.27.jar。

我不想将数据源配置放在应用程序中（没有META-INF ....），因为jndi的一个目标是将数据源信息放在应用程序之外。

感谢您阅读并花费时间查找解决方案。

你还没有定义jdbc/TestDB是什么地方，因此你没有数据库驱动 –

是的，'context.xml'是错误的，应该包含'jdbc/TestDB'的定义。在答案中添加了正确的'config.xml'。 – MariuszS

我在我的文章中犯了一个错误。我刚更新了web.xml和tomcat context.xml（eclipse） – user3178994

，我终于找到了解决办法，我会与谁遇到了同样的问题分享。

将src/main/webapp下的META-INF文件夹创建为WEB-INF sibling 将Tomcat-config/context.xml文件移至META-INF文件夹。你会在pom.xml中看到这个文件不会成为WAR文件的一部分。

META-INF/context.xml的

<?xml version="1.0" encoding="UTF-8"?> 
<Context> 

    <!-- Default set of monitored resources --> 
    <WatchedResource>WEB-INF/web.xml</WatchedResource> 

<Resource name="jdbc/TestDB"

      password="xxxxxxxxxx" 
      driverClassName="com.mysql.jdbc.Driver" 
      url="jdbc:mysql://localhost:3306/TestDB" 
      auth="Container" 
      type="javax.sql.DataSource" 
      maxActive="100" 
      maxIdle="30"

的Eclipse /运行宣布 - 运行配置...

  • 创建新的启动配置
  • 基地direrctory $ {workspace_loc：/项目名称}

  • 目标干净tomcat7：运行

  • 应用

  • 运行

下一次，你可以在附近的运行方式......在工具栏按钮上的箭头单击并选择要运行的配置。 “停止”和“重新启动”按钮非常有用。

我认为你可以简化这个配置，如果这不是你的要求，就不要使用JEE资源:) Spring对环境配置，配置文件等有非常好的支持。 – MariuszS

我觉得你的tomcat安装不使用你的context.xml。请创建新鲜的tomcat，配置context.xml和libs并直接从系统运行Tomcat（无需Eclipse等）。

问题进行了更新，回答以下是过时：/

最重要的部分是：

Cannot create JDBC driver of class '' for connect URL 'null'

你的驱动程序类是null和连接URL是null。

应用配置需要在服务器上配置资源jdbc/TestDB：

<resource-ref> 
    <description>DB Connection</description> 
    <res-ref-name>jdbc/TestDB</res-ref-name> 
    <res-type>javax.sql.DataSource</res-type> 
    <res-auth>Container</res-auth> 
</resource-ref>

和

<jee:jndi-lookup id="dataSource" 
    jndi-name="jdbc/TestDB" 
    expected-type="javax.sql.DataSource" 
    resource-ref="true"/>

但是你的Tomcat配置Servers/tomcat-config/context.xml是错误的。它看起来像弹簧应用程序配置。

<web-app id="WebApp_ID" version="2.4" 
    xmlns="http://java.sun.com/xml/ns/j2ee" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee 
         http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> 

...

标准的Tomcat context.xml看起来是这样的：

<?xml version='1.0' encoding='utf-8'?> 
<Context> 
<Resource name="jdbc/TestDB" auth="Container" type="javax.sql.DataSource" 
    username="user" password="pass" 
    driverClassName="com.mysql.jdbc.Driver" 
    url="jdbc:mysql://localhost:3306/testDB?characterEncoding=utf8" maxActive="8"/> 

</Context>
