Question

我正在尝试在tomcat中配置db2数据库的数据源（使用eclipse作为IDE），但是我无法解决问题，Tomcat给我发了以下异常：

我把DB2的jdbc文件放在哪里？我尝试在每个地方（在项目的库中，在tomcat安装目录的lib文件夹中，在Dinamic Web项目的WEB-INF / lib文件夹中，在eclipse中的tomcat类路径“tomcat server”配置中到目前为止）

此致

ps。：我正在使用：

DB2 9.7 雄猫6 JDK 1.6 Eclipse Galileo

您需要将它放在Eclipse的/lib文件夹中，或者放在shared.loader中common.loader或/conf/catalina.properties属性中指定的任何路径中。如果它没有解决问题，那么它就不是你认为Eclipse正在使用的正确的Tomcat实例。

如果一切顺利（删除服务器库中的JDBC驱动程序），那么您应该看到它出现在 [ProjectName] / Java Resources（src）/ Libraries / [ServerName] 列表中Project Explorer。
