JNDI lookup failed (NameNotFoundException)

Question

UPDATE: Well, it seems that this is a problem only when I try to debug locally. When published on Jetty (not the same machine) it works great. Is it possible to configure the jetty.xml file used by Run-Jetty-Run when debugging locally?

I just wasted an afternoon trying to find the cause of this, but with no success...

I'm setting up a connection pool with c3p0 for my application. I'm using Jetty 7, by the way. The problem is that when I do a context.lookup get a datasource, I get this exception:

I have a jndi.properties file to configure my InitialContext (located in my resource folder src/main/resources)

java.naming.factory.url.pkgs=org.eclipse.jetty.jndi
java.naming.factory.initial=org.eclipse.jetty.jndi.InitialContextFactory

I also have a jetty-env.xml file in the webapp/WEB-INF folder:

<Configure class="org.mortbay.jetty.webapp.WebAppContext">

<!--<Set name="ConfigurationClasses">
   <Ref id="plusConfig"/>
</Set>  -->

<!-- MySql datasource org.eclipse.jetty.plus.jndi.Resource Factory-->
<New id="DSTest" class="org.mortbay.jetty.plus.naming.Resource">
    <Arg></Arg>
    <Arg>jdbc/DSTest</Arg>
    <Arg>
     <New class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <Set name="driverClassName">com.mysql.jdbc.Driver</Set>
        <Set name="url">jdbc:mysql://host/</Set>
        <Set name="username">username</Set>
        <Set name="password">password</Set>
        <Set name="checkoutTimeout">5000</Set>
        <Set name="initialPoolSize">10</Set>
        <Set name="maxIdleTime">30</Set>
        <Set name="maxPoolSize">160</Set>
        <Set name="minPoolSize">10</Set>
        <Set name="maxStatements">200</Set>
        <Set name="maxConnectionAge">0</Set>
        <Set name="acquireIncrement">15</Set>
    </New>
  </Arg>
 </New>
</Configure>

And I added those lines in my web.xml file:

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

I seem to have followed all the required steps, but I still get a javax.naming.NameNotFoundException when doing the lookup...

Any hints?

Thanks!

EDIT: I forgot to put how I do my lookup.

InitialContext ctx = new InitialContext();
DataSource dataSource = (DataSource)ctx.lookup("java:comp/env/jdbc/DSTest");

Stupid question but this page http://docs.codehaus.org/display/JETTY/JNDI#JNDI-resref states that using JNDI with Jetty is an optional feature that needs to be enabled.

Specifically it says The class that does this is org.mortbay.jetty.plus.webapp.Configuration, and we specify its name in the list of configurations to be applied to the webapp when we define the org.mortbay.jetty.webapp.WebAppContext for it.
