ConnectionEvent

public class ConnectionEvent
extends EventObject

java.lang.Object
   ↳ java.util.EventObject
     ↳ javax.sql.ConnectionEvent


An Event object that provides information about the source of a connection-related event. ConnectionEvent objects are generated when an application closes a pooled connection and when an error occurs. The ConnectionEvent object contains two kinds of information:

  • The pooled connection closed by the application
  • In the case of an error event, the SQLException about to be thrown to the application
