Modifying a Web Client
After you generate an InterSystems IRIS® web client class, you do not usually edit the class. Instead you write code that creates an instance of that class and that provides provide client-side error handling. This topic discusses various ways to fine-tune the InterSystems IRIS web client, either by modifying the web client instance or (less commonly) by modifying the generated class.
Do not create a subclass of the generated web client class. The compiler will not generate the supporting classes that it would need in order to run properly, and your subclass would not be usable.
