Re: [jetty-users] NameNotFoundException on JNDI lookup

resource-ref in web.xml is typically the most portable way to wire a jndi resource into a webapp, jetty-env.xml typically lets you wire in jetty specific container configuration for declaring that jndi resource inside of the webapp....personally I prefer not seeing jetty-env.xml in a webapp and let the container configure it in a context.xml or globally in a jetty.xml formatted file.

Do I need to add a <resource-ref> to web.xml to get JNDI working or Is it fine to configure jetty-env.xml as I did?

Your webServer.start() occurred after you attempted to lookup the JNDI reference.
That's not going to work, as the deployment of the WebAppContext is the one that sets up the JNDI reference.

You essentially asked for the information before the information even existed.

Move the webServer.start() to before the InitialContext reference.

I need to implement JNDI for Jetty 9.0.3 web server for H2 database using C3p0 connection pooling, I've placed both H2 and C3p0 jars in lib/ext of JETTY-HOME directory and I've created a jetty-env.xml file in my WEB-INF.


 <?xml version="1.0"?>

I'm implementing embedded jetty with plus configuration enabled, by creating an instance of Jetty server from the main method of below class :

import javax.naming.Context;
import javax.naming.InitialContext;
import javax.sql.DataSource;
import org.eclipse.jetty.server.Server;
import org.eclipse.jetty.util.resource.ResourceCollection;
import org.eclipse.jetty.webapp.WebAppContext;

public class WebServer

    public static void main(String[] args)
        // Creating Jetty Server on port 8080
        Server webServer = new Server(8080);
        org.eclipse.jetty.webapp.Configuration.ClassList classlist = org.eclipse.jetty.webapp.Configuration.ClassList.setServerDefault(webServer);
        classlist.addAfter("org.eclipse.jetty.webapp.FragmentConfiguration", "",
        WebAppContext wac = new WebAppContext();
        // Set WAR Path to WebAppcontext from disk
        File warPath = new File("C:/Users/XXXX/src/com/UI");
        wac.setBaseResource(new ResourceCollection(new String[] { "./WebContent", "build/classes" }));
            InitialContext ic = new InitialContext();
                DataSource myDS = (DataSource)ic.lookup("java:comp/env/jdbc/testDS");     
            System.out.println("param ::: "+myDS);
        catch (Exception e)



I get following error, how can I resolve this?

javax.naming.NameNotFoundException; remaining name 'env/jdbc/testDS'
