Struts2 session bean and Container.setScopeStrategy exception

[Bob Dietrich]

I'm using Struts2 and the built-in dependency injection. I have a bean defined in struts.xml:

<bean name="tracker" class="com.foo.beans.TrackerBean" />

This POJO bean is currently injected into an action class via:

@Inject( "tracker")
public void setTracker( TrackerBean bean)
...

I then tried to make sure the bean contents persisted for the session, so I modified the declaration:

<bean name="tracker" class="com.foo.beans.TrackerBean" scope="session" />

Now when the code starts up, I get the following exception:

At this point I'm thoroughly confused by the error message, including what "Container" is referenced. Suggestions please? Thanks.

Any suggestions please?
