I am trying to get Spring working with tomcat JNDI resource to access my database. My project works if a META-INF/context.xml in my project with the resource information but once I remove it it stops.. why.

推荐答案

如果在Tomcat中部署Web应用程序，则在部署过程中，Tomcat将复制$ CATALINA_HOME/conf/中的META-INF/context.xml文件.上下文将可用于您的应用程序.请记住，如果因为不希望从应用程序中删除context.xml，则还必须从$ CATALINA_HOME/conf/

If you deploy a Web application in Tomcat, in the deployment process, Tomcat will copy the META-INF/context.xml file in $CATALINA_HOME/conf/ so the context will be available for your application. Take in mind, that if you remove context.xml from you application because you dont want it, you also have to delete it manually from $CATALINA_HOME/conf/

如果您已编辑server.xml以包含dababase资源，并且在删除context.xml时不起作用，则可能是因为在server.xml中定义资源时出错了

If you have edited the server.xml for including your dababase resource and is not working when you remove context.xml it could be because you made some mistake defining your resourde in server.xml

已更新:

当资源位于server.xml中时，在上下文中，您应该引用server.xml中的全局资源.例如:

When resource is in server.xml, in context you should make a reference to global resource in server.xml. For example:

<Context crossContext="true" reloadable="true" >
    <ResourceLink name="jdbc/myApp" type="javax.sql.DataSource" global="jdbc/myApp" />
</Context>
