Jetty 6 Eclipse Datasource NameNotFoundException

I try to configure a data source for a Jetty 6 Server in my Eclipse Project.

I include these jars in my lib folder:

common-dbcp-1.4.jar
commons-pool-1.5.6.jar
jetty-naming-6.1.14.jar
the jetty-plus-6.1.11.jar

Here is the jetty-env.xml from the WEB-INF:

<?xml version="1.0"?>
<!DOCTYPE Configure PUBLIC "-//Mort Bay Consulting//DTD Configure//EN" "http://jetty.mortbay.org/configure.dtd">

<Configure id="myapp" class="org.mortbay.jetty.webapp.WebAppContext">
    <New id="DSTest" class="org.mortbay.jetty.plus.naming.EnvEntry">
        <Arg><Ref id="myapp" /></Arg>
        <Arg>jdbc/DSTest</Arg>
        <Arg>
            <New class="org.apache.commons.dbcp.BasicDataSource">
                <Set name="driverClassName">org.postgresql.Driver</Set>
                <Set name="url">dbc:postgresql://localhost:5432/schoeneberg</Set>
                <Set name="username">postgres</Set>
                <Set name="password">deluxe</Set>
            </New>
        </Arg>
    </New>
</Configure>

My web.xml from the WEB-INF

<?xml version="1.0" encoding="utf-8"?>

        <servlet-name>test</servlet-name>
        <url-pattern>/test</url-pattern>
    </servlet-mapping>
</web-app>

and here the Servlet Code:

@SuppressWarnings("serial")
public class Test extends HttpServlet {

    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp)
            throws ServletException, IOException {
        try {

            Context env = (Context) new InitialContext().lookup("java:comp/env/jdbc/DSTest");
        } catch(Exception ex) {
            ex.printStackTrace();
        }
    }
}

Seems to be a simple Example for Datasources and Connection Pooling in Jetty 6. But I always get this Exception:

Anybody an idea?

Thanks for help!

try only with the resource name:

final Context ctx = new InitialContext();
final DataSource ds = (DataSource) ctx.lookup("jdbc/DSTest");

It's works for me
