[jboss-user] [EJB 3.0] - Re: Why is injection not working in AS 4.0 and 4.2 (servlets

[Zyborg]

hi all!

my application is packed into a .ear file and gets deployed into a jboss 5 beta2.
i am trying to inject a EntityManager from a servlet without success ...
should my scenario work or is there something i misunderstood?
maybe its just a deployment failure - so i packaged my ear file note correctly?
i ran out of ideas ... please help!

the ear file structure looks like:

  | META-INF/
  |   |-- jboss-app.xml
  |   |-- application.xml
  | beans.jar
  |   |--META-INF/
  |        |--persistence.xml
  |   |--com/
  |        |--myapp/
  |              |--...
  | web.war
  |   |--WEB-INF/
  |         |-- classes/
  |         |-- lib/
  |         |--web.xml
  | 

jboss-app.xml:

  | <!DOCTYPE jboss-app
  |           PUBLIC "-//JBoss//DTD J2EE Application 1.4//EN"
  |           "http://www.jboss.org/j2ee/dtd/jboss-app_4_0.dtd">
  | <jboss-app>
  |   <loader-repository>
  |     com.myapp:loader=MyApp.ear
  |   </loader-repository>
  | </jboss-app>
  | 

application.xml:

  | <?xml version="1.0" encoding="UTF-8"?>
  | <application>
  |     <display-name>My Application Title</display-name>
  |     <description>My Application Title Description</description>
  | 
  |     <module>
  |       <ejb>beans.jar</ejb>
  |     </module>
  | 
  |     <module>
  |         <web>
  |             <web-uri>web.war</web-uri>
  |             <context-root>MyApp</context-root>
  |         </web>
  |     </module>
  | </application>
  | 

the injection code in the servlet looks like:

  | 	@PersistenceContext(unitName="MyUnit")
  | 	private EntityManager em;
  | 


On deployment i get following error:

  | java.lang.RuntimeException: @PersistenceContext(name='env/com.myapp.server.MyServiceImpl/em',unitName='MyUnit') on EJB: web.war failed to inject on field private javax.persistence.EntityManager com.myapp.server.MyServiceImpl.em Unable to find persistence unit: MyUnit for deployment: web.war
