JNDI Lookup fails on Liberty Profile

I'm using Liberty Profile v8.5.5.5 (WebSphere Application Server 8.5.5.5/wlp-1.0.8.cl50520150221-0034) on IBM J9 VM, version pxa6470sr1-20120330_01 (SR1) (en_US)

I have the jndi feature installed...but no matter what I do, I can't do a simple JNDI lookup.

In my server.xml

<jndiEntry jndiName="schoolOfAthens/defaultAdminUserName" value="plato" />

My code... (Which is just a servlet of a few lines)

Object jndiConstant = new InitialContext().lookup(
"schoolOfAthens/defaultAdminUserName");

But this fails with:

javax.naming.NameNotFoundException: Name schoolOfAthens not found in context "serverlocal:CELLROOT/SERVERROOT".

The code is taken directly from an example.

Any ideas?

I am running this locally and have also tried on my Bluemix account... Same result

Same works for me on 8.5.5.6, don't have .5 at hand but should work in the same way.

Here is my my server.xml:

<server description="new server">

    <!-- Enable features -->
    <featureManager>
        <feature>servlet-3.1</feature>
        <feature>jndi-1.0</feature>
        <feature>localConnector-1.0</feature>
    </featureManager>

    <!-- To access this server from a remote client add a host attribute to the following element, e.g. host="*" -->
    <httpEndpoint httpPort="9080" httpsPort="9443" id="defaultHttpEndpoint"/>


    <applicationMonitor updateTrigger="mbean"/>

    <webApplication id="JNDITest" location="JNDITest.war" name="JNDITest"/>
    <jndiEntry jndiName="schoolOfAthens/defaultAdminUserName" value="plato" />    
</server>

And servlet code (take a look that you can also use @Resource annotation instead of lookup):

@WebServlet("/JNDIServlet")
public class JNDIServlet extends HttpServlet {
    @Resource(lookup="schoolOfAthens/defaultAdminUserName")
    String jndiVariable;

    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        try {
            InitialContext ctx = new InitialContext();
            Object object = ctx.lookup("schoolOfAthens/defaultAdminUserName");
            System.out.println("object: " + object);
            System.out.println("jndiVariable: " + jndiVariable);
        } catch (NamingException e) {
            e.printStackTrace();
        }
    }

}

with output: 

object: plato
jndiVariable: plato

ok , got this to work. I added a resource-ref to my web.xml and looked it up like this:

 Object obj2 = ctx.lookup("java:comp/env/schoolOfAthens/defaultAdminUserName");`

web.xml

 <resource-ref>
     <description>Test Reference</description>
     <res-ref-name>schoolOfAthens/defaultAdminUserName</res-ref-name>
     <res-auth>Container</res-auth>
 </resource-ref>
