您是否尝试过没有'java:/ comp/env /'前缀的查找? – nitind

在server.xml中试试这个

<Resource name="jdbc/data" auth="Container" type="javax.sql.DataSource" 
     maxActive="15" maxIdle="3" maxWait="10000" 
     username="root" password="password" 
     url="jdbc:mysql://localhost:3306/data" driverClassName="com.mysql.jdbc.Driver" 
      /> 

我在上面的代码中更改了网址,其中数据是您的数据库名称。

这是tomcat的配置错误。使用http://www.mkyong.com/tomcat/how-to-configure-mysql-datasource-in-tomcat-6/做配置 – yash

但这种方式访问​​数据库的数据将保持在上下文中,但我会这些都在GlobalNamingResources中。有可能做到这一点?否则我会尝试这种方式 – Kuroi
