Method Detail

onEvent

public com.bea.wlpi.server.eventprocessor.EventData[] onEvent(com.bea.wlpi.server.eventprocessor.EventData eventData)
                                                       throws PluginException

Handle an incoming event. The event processor calls this method when it receives an event message (usually via JMS) that is addressed to a specific plugin. If the event handler merely transforms the incoming data to a different format (typically XML), it should return the transformed data, with appropriate content type and other attributes set. Event handlers that completely process the incoming event internally should return null. Event handlers can also translate a single incoming event into multiple outgoing events for the event processor to handle sequentially.

Returns:

Transformed event data, to be handled by the standard event processor.
