virgo + springDM + custom Application Context Listener [message #813421]

Suppose I want to register a custom application context listener. SpringDM books says I must do something like this:

<beans:bean id="osgiApplicationContextListener" class="org.springframework.osgi.extender.internal.activator.ListListenerAdapter">
<beans:constructor-arg>
<beans:list>
<beans:bean class="org.springframework.osgi.extender.internal.support.DefaultOsgiBundleApplicationContextListener"/>
<beans:bean id="myTest" class="com.eugene.ApplicationContextListener"/>
</beans:list>
</beans:constructor-arg>
</beans:bean>

This is created in META-INF/spring/app-config.xml

Create, deploy the bundle, then I get this Exception:

Is there a setting that i am missing about or why can't it find the class. Bundle :

30|Active | 1|spring-osgi-extender (1.2.1)

is active.

Sounds to me this is a bug, but may be I am missing something.

Thank You,
Eugene.

Please see the Virgo FAQ for how to diagnose class loading errors. I notice that the package containing the class appears to be internal, so perhaps it is not exported?
