Exception and error management

This feature controls the errors and exceptions that are managed by the operations.

The following standard functions are provided:

In the toolkit configuration file (btt.xml) in the server side, the errorPage value under the KeyedCollection portal is the name of a JSP that is displayed when a system exception occurs. When this page is displayed by the portal presentation handler, the exception itself is saved in the request under the key name, exception. The JSP can use the JSP Context Services bean to check the errors which are detected during the data validation process. Then the JSP can retrieve and manage the specific data field error.
