Event Notification Endpoint in Java

I've created a WebService annotated class that implements

events_occurred

to act as an endpoint and handle the SOAP message sent via the F5 subscription service. When I have an event hit my endpoint I get an error when deserializing the

event_data_list

param.

INFO: No default constructor found on class iControl.ManagementEventSubscriptionEventType
java.lang.NoSuchMethodException: iControl.ManagementEventSubscriptionEventType.()

Am I taking the right route to implement an endpoint for Event Notifications (Java WS)? If I am, how can I expose a constructor for the

iControl.ManagementEventSubscriptionEventType

?

Thanks for any help.
