[jetty-users] Getting JNDI/ db connection pool to work

[Bill Ross <ross@xxxxxxxxxxxx>]

I have:

----- src/main/webapp/WEB-INF/web.xml

...
<resource-ref>
  <description>DataSource</description>
  <res-ref-name>jdbc/pr</res-ref-name>
  <res-type>javax.sql.DataSource</res-type>
  <res-auth>Container</res-auth>
</resource-ref>
...

----- src/main/webapp/WEB-INF/jetty-env.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE Configure PUBLIC "-//Mort Bay Consulting//DTD Configure//EN" 
"http://www.eclipse.org/jetty/configure.dtd";>

------ src/main/java/com/priot/servlet/GetSession.java

import javax.naming.InitialContext;
import javax.naming.NamingException;
import javax.sql.DataSource;

            InitialContext ic = new InitialContext();
            DataSource ds = (DataSource)ic.lookup("java:comp/env/jdbc/pr");

--- Thrown on ic.lookup():

It's as if my jetty-env.xml isn't being seen? But it is there in the war 
file (along with the .swp).

Am I missing something obvious?

Thanks,
Bill
