    text
    copied!<p>I'm trying to implement my HK2 binding in Jersey, in a servlet / tomcat context.</p> <p>I do, in a servlet which extends org.glassfish.jersey.servlet.ServletContainer :</p> <pre><code> @Override public void init(ServletConfig config) throws ServletException { super.init(config); // BinderInjection extends org.glassfish.hk2.utilities.binding.AbstractBinder getConfiguration().register(new BinderInjection()); } </code></pre> <p>... but I get :</p> <pre><code>java.lang.IllegalStateException: The resource configuration is not modifiable in this context. at org.glassfish.jersey.server.ResourceConfig$ImmutableState.register(ResourceConfig.java:270) at org.glassfish.jersey.server.ResourceConfig$ImmutableState.register(ResourceConfig.java:218) at org.glassfish.jersey.server.ResourceConfig.register(ResourceConfig.java:448) at A_Servlet.init(RestServlet.java:45) at org.apache.catalina.core.StandardWrapper.initServlet(StandardWrapper.java:1190) </code></pre> <p>So how can I do my own HK2 binding ?</p> <p><strong>Why this question ? (edit)</strong></p> <p>It's for EntityManager and JPA in Jersey.</p> <p>With Netbeans, if I generate an AbstractFacade it put </p> <pre><code> @PersistenceContext(unitName = "myunit") private EntityManager em; </code></pre> <p>... and :</p> <pre><code> @Override protected EntityManager getEntityManager() { return em; } </code></pre> <p>But, when I call the service, em is null. So I suppose it's @PersistenceContext which doesn't work ?</p> <p>If I use the solution <a href="http://scn.sap.com/people/maxim.maltsev/blog/2012/12/11/put-jpa-in-your-web-app-tomcat-eclipselink" rel="nofollow">Tutorial: Put JPA in your Web App (tomcat, EclipseLink) and provide Rest JSON output</a> all work like a charm, but I don't like use static variable <em>private static EntityManagerFactory emf;</em> for entity manager.</p> <p>Thanks.</p>
