External jdbc not found on latest Confluence Server

Hi,

I updated my Confluence Sever to version 6.14.1.

And even external datasource is added to ./conf/server.xml.

I get this error. How to fix?

Cause

javax.naming.NameNotFoundException: Name [jdbc/agileapplicationstack] is not bound in this Context. Unable to find [jdbc].
    at org.apache.naming.NamingContext.lookup(NamingContext.java:817) 

Sorry. sever.xml was not configured correct.
