A method and a system for dynamically specifying exceptions and exception handlers for an application written in any computer language, which has exception handling facility, are described. The present decouples the exception handling logic from the application and thereby can be used to alter the behavior of the program/module/application as well as to define new types of exceptions at runtime. The decoupling of the exception handler logic eliminates the language dependence of the application and further helps in customizing the behavior of the application when they are being deployed in new environments. Moreover dynamic exception handling is not operating system dependent.
