[jboss-user] [EJB 3.0] - Injecting an EJB into a Servlet

[javidjamae]

I'm trying to inject an EJB into a Servlet in JBoss 5 CR2. I have an ear called video.ear. The ear has a video.war, video.jar, and video.har in it (though the har should be irrelevant).

The binding 

Here is my Servlet Code:


  | public class VideoServlet extends HttpServlet {
  | 	@EJB(mappedName="video/VideoServiceImpl/local")
  | 	private VideoService videoService;
  | 

I'm not sure if I have to put the "mappedName" on there, but I tried it without and it didn't work.

My web.xml has the correct schema:

  | <web-app xmlns="http://java.sun.com/xml/ns/javaee"
  | 	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  | 	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
  | 	version="2.5">
  | 

I noticed I had this in the log

  | 22:46:34,065 WARN  [MappedReferenceMetaDataResolverDeployer] Unresolved references exist in JBossWebMetaData:[video.war#web-app:AnnotatedEJBReferenceMetaData{name=videoService,ejb-ref-type=null,link=null,ignore-dependecy=false,mapped/jndi-name=video/VideoServiceImpl/local,resolved-jndi-name=null,beanInterface=interface

  | .
  | .
  | .
  | 22:46:42,237 INFO  [TomcatDeployment] deploy, ctxPath=/video, vfsUrl=video.ear/video.war
  | 

When I try to access the servlet, I get:

  | 22:49:54,654 INFO  [[/video]] Marking servlet Video as unavailable

Any ideas?
