    WELD with embedded Jetty

    Ed Ross Newbie

      I've been trying to figure out how to run weld with an embedded version of jetty and not having much luck (in fact, i can not seem to get it to run under jetty at all).  I seem to get a host of strange errors that I can not seem to resolve.

       

      When running under jetty I will get this following error:

       

      java.lang.RuntimeException: WELD-ENV-001024: Could not bind BeanManager reference to JNDI: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file:  java.naming.factory.initial|If the naming context is read-only, you may need to use a configuration to bind the BeanManager instead, such as Tomcats context.xml or Jettys jetty-web.xml.

       

      this would seem I don't have a web.xml and/or a jetty-env.xml - both which exist and seem proper.

      So far - so good.  However when I have an injectable component I get

          Hi Ed,

          Well it is really not clear to me. Which version of Jetty do you use? The stacktrace you provided looks more like some Jersey integration problem but I might be wrong. Can you point me to SystemInjecteeImpl code? Do you have any reproducer? I am not Jersey expert but this looks quite similar http://stackoverflow.com/questions/30230070/org-glassfish-hk2-api-unsatisfieddependencyexception-there-was-no-object-ava…

            Thanks for the quick response.

             

            This is a very simple example. When I take out weld and create the injectable manually – works fine.  When I try and use CDI, it cannot find it.

             

            FYI – I currently use weld with deltaspike in several other projects that run under Tomcat.  I am trying to create a standalone jar that I can run with the java –jar and have an embeddable container.

             

             

            Injectable class -

            package com.cc;

             

            import java.util.Random;

             

            public class Injectable {

             

                public String getRangom() {

                    final Random rand = new Random();

                    final int i = rand.nextInt();

                    final String str = new Integer(i).toString();

                    return str;

             

                }

            }

             

            Service Class

            package com.cc;

             

            import javax.inject.Inject;

            import javax.ws.rs.GET;

            import javax.ws.rs.Path;

            import javax.ws.rs.Produces;

            import javax.ws.rs.core.MediaType;

             

            @Path("/entry-point")

            public class Service1 {

                @Inject

                Injectable inj;

             

                @GET

                @Path("test")

                @Produces(MediaType.TEXT_PLAIN)

                public String test() {

                    String results = "none";

                    if (this.inj != null) {

            results = this.inj.getRangom();

                    }

                    return results;

                }

            }

              Tomas Remes Expert

              Ok. So I reproduced the problem. My interpretation is following: org.glassfish.jersey.servlet.ServletContainer (note that jersey-container-servlet-core is for Servlet 2.x) uses HK2 as javax.inject implementation and HK2 doesn't likely know anything about CDI beans. The problem is discussed at http://stackoverflow.com/questions/18963627/how-to-integrate-jax-rs-with-cdi-in-a-servlet-3-0-container but it doesn't include Jetty. You can try to include dependency to jersey-gf-cdi-ban-custom-hk2-binding but it didn't help to me.  I wonder whether you need to use Jetty? Wouldn't be Jersey Grizzly HTTP container sufficient? This should work jersey/examples/cdi-webapp at master · jersey/jersey · GitHub
