Hi to all

 i need a hand about the configuration of a jboss portal event listener, useful for creating a portlet "A" that communicates with a portlet "B" sending some parameters that the second potlet receive and use. 

well, i have written all classes, but i can't make the listener work because the server consolle returns an error of type: java.lang.ClassNotFoundException: No ClassLoaders found for: ch.teamlab.ristur.demo.RisTurJsp$Listener 

can you help me to fix this bug please? 

i have some other questions too:
1) in order to execute the portlet method processAction() is necessary that a client submit an html form? 
2) the signature of the method onEvent() , into the listener definition, exists in two different flavours, one i have found in the jboss portal reference guide(chapter 12) , and another a different manual(chapter 6) 

public PortalNodeEvent onEvent(PortalNodeEventBubbler bubbler, PortalNodeEvent event) 

public PortalNodeEvent onEvent(PortalNodeEventContext context, PortalNodeEvent event) 

the main difference is the type of the first parameter passed to the method: a class of type PortalNodeEventBubbler in one case and PortalNodeEventContext in the other : what are the differences beetween this 2 approaches and witch one works better? 

thank you very much.
