在我的Tomcat 7服务器中配置的Oracle 10g JNDI数据源无法正常工作

标签： hibernate spring-mvc oracle10g tomcat7 jndi

所以我在Tomcat 7 context.xml中设置了JNDI。 这应该连接到我的Oracle 10g数据库。 我在Tomcat＆＃39; s / lib文件夹中包含了classes12dms_g.jar，orai18n.jar，ojdbc14dms_g.jar和ons.jar。

出于某种原因，当我在Tomcat上部署我的应用程序时，它会抛出错误。

好的，这个问题的解决方案是通过从eclipse而不是从文件系统配置tomcat来解决的。将Tomcat服务器添加到名为包含context.xml的服务器的eclipse时，会在Package Explorer中添加一个文件夹。

作为旁注，我在做完这个后遇到了另一个问题。如果你想使用dms jar你需要另一个名为dms.jar的jar，所以我只是降级到classes12.jar和ojdbc14.jar。
