Injection inside HttpSessionAttributeListener

[claudio4j]

Hi folks,

Is it possible to inject a seam component for  HttpSessionAttributeListener
I want to inject a component loaded from components.xml into a HttpSessionAttributeListener implementation. The code looks like:

MyInterface obj = (MyInterface) org.jboss.seam.Component.getInstance("obj", true);

But there is an exception:

java.lang.IllegalStateException: No application context active
        at org.jboss.seam.Component.forName(Component.java:1945)

The listener declaration is after SeamListener in web.xml

JBoss seam is 2.2.0
JBoss 5.0

If the injection is not officialy supported in seam, is there a workaround for this ?

Thanks

Claudio

More information.
The implementation class is

 @Name("obj")
 @Install(false)
 @Scope(ScopeType.APPLICATION)
 @AutoCreate
 public class MyImplementation implements MyInterface

I have tried with
@Scope(ScopeType.SESSION)

The components.xml

    <component  class="br.com.MyImplementation" 
                name="obj">
    </component>
