Hi everyone,

I'm just wondering when/why you would define a resource-ref element in your web.xml file?

I would have thought that it would be defined in your web/app server using JNDI and then look up the JNDI reference in your Java code?

The resource-ref definition seems a bit redundant to me and I can't think of when it might be useful. Example:

<resource-ref>
  <description>Primary database</description>
  <res-ref-name>jdbc/primaryDB</res-ref-name>
  <res-type>javax.sql.DataSource</res-type>
  <res-auth>CONTAINER</res-auth>
</resource-ref>

Thanks!
