Spring using JNDI with Tomcat... why do I need a META-INF/context.xml in my project

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.

Solution

  • 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/

    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

    UPDATED:

    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>
