Abstract: A system is presented to allow users in an instant messaging environment to edit already-exchanged messages dynamically, and resend the edited version of the message to the target users, as an example. The newly edited message received by the second user is clearly understandable because the corrected parts of the message have been tagged. Depending on the implementation, either a new complete and corrected message is sent, or the sent message indicates the recent editions. The advantage of this solution is that all that the altering user should do is to go over the communication text, change or edit the text, and press ENTER.

Abstract: A system and method for implementing dynamic interfaces in a JAVA program including methods having a common implementation and other methods to be handled independently. The system comprises a first dynamic proxy object implementing an invocation handler for providing default implementations; a separate object providing implementations of any method in a defined interface that requires independent handling; and, a second dynamic proxy object provided for checking a method definition object for an implementation of the method, and in response, one of: invoking the method on the separate object if the implementation exists, and if the implementation does not exist, invoking the method on the first dynamic proxy object. The second dynamic proxy object thus allows for a single implementation for repetitive methods, while allowing special cases to be handled independently.
