Problem with injection EJB in Weblogic

I'm using Weblogic 10.0 to develop my application.

I create a project with JBoss Tools and add an ant build file to create my weblogic EAR.

Then the problem:

I need to develop my application with a layered architeture. My project has a Action layer this layer access only a manager layer that contain only business rules and this layer only access a DAO layer that is responsible to persist model objects into database. All layers are session beans.

I have to inject a UserManager into UserAction then I use

@In(autoCreate = true)
UserManager userManager;

to inject. But I got this error:

I solved the problem using @EJB annotation to inject the UserManager but all seam components injected in UserManager session bean like @Logger stopped to work.

I try to run the same example in JBoss and it works fine with

@In(autoCreate = true)
