    Wildfly 10 EJB-Project injection EJB in separat JSF-Application

    Reik Loeber Newbie

      Hello,

      i have a problem while injection EJB's in a JSF 2.2 webapp.

       

      Project-Structure :

       

      EAR-Project:

      - project-api.jar (only interfaces)

      - project-impl.jar (remote ejb's which implements the interfaces of project-api.jar

       

      ex.:

       

      project-api.jar

      public interface MyRemoteBean {
           public void test();
      }
      

       

      project-impl.jar

      @Remote(MyRemoteBean.class)
      @Stateless
      public class MyRemoteBeanImpl implements MyRemoteBean {
           @Override
           public void test(){
            ...
           }
      }
      

       

      Output of wildfly at deploy-time:

       

      java:global/myproject-ear-1.0-SNAPSHOT/project-impl-1.0-SNAPSHOT/MyRemoteBeanImpl!com.example.projectapi.MyRemoteBean
        java:app/project-impl-1.0-SNAPSHOT/MyRemoteBeanImpl!com.example.projectapi.MyRemoteBean
        java:module/MyRemoteBeanImpl!com.example.projectapi.MyRemoteBean
        java:jboss/exported/myproject-ear-1.0-SNAPSHOT/project-impl-1.0-SNAPSHOT/MyRemoteBeanImpl!com.example.projectapi.MyRemoteBean
        java:global/testenterprise-ear-1.0-SNAPSHOT/project-impl-1.0-SNAPSHOT/MyRemoteBeanImpl
        java:app/project-impl-1.0-SNAPSHOT/MyRemoteBeanImpl
        java:module/MyRemoteBeanImpl
      

       

      I have a JSF2.2 webapp (not in the EAR-Project !)

      In the pom.xml of the webapp :

       

      <dependency>
      <groupId>...</groupId>   
      <artifactId>project-api</artifactId>
      <version>...</version>
      </dependency>
      

      In this way i can code against the api with no knowing of implementation.

       

      In a JSF-Bean :

      @Named
      @ViewScoped
      @JBossLog
      public class MyViewController implements Serializable {
           private static final long serialVersionUID = 1L;
      
           @EJB
           private MyRemoteBean remoteBean;
      
          public String uiButtonPressed(){
                log.info("bean initialized with: "+remoteBean;
           }
      }
      

      remoteBean is always null

      output of wildfly :

       

      WFLYWELD0044: Error injecting resource into CDI managed bean. Can't find a resource named java:comp/env/com.example.webapp.MyViewController/remoteBean
      

       

      I don't want the ejb project as an dependency of the webapp because if i have deployed the ear and later i deploy the webapp, all ejb's will be deployed twice.

      My thinking, i develop an api (the project-api.jar), the implementation (myproject-impl.jar), both packed in an ear to provide the ejb's. This ear will be deployed to wildfly. Then i can code several webapps (or whatever) and only need the myproject-api.jar as a dependency.

      I think many of provided libraries use this technic. faces-api, faces-impl for example.

       

      Is there a way to do so i want?

       

      Sorry for my english
