A system and method for creating applications, such as web applications, is disclosed. The system may comprise a controller generator that is adapted to provide an application with a controller that receives a request for data from a user and responds to the request by sending information to the user. The system may also include an error handler generator that is adapted to provide an error handler that performs error handling functionality during operation of the application if an error occurs during the processing of the request for data based on error data that is stored in an error catalog.
