- '''Problem'''
- Struts provides { { { ActionMessages/ActionErrors } } }classes for maintaining a
stack of error message to be reported, which can be used with JSP tags like <html:
error> to show these message to the user. The problem starts when you have to report
different category/severity of message in a different manner. There are two aspects of
this problem
- * Throwing error message of different { { { category/Severity } } }

-Struts { { { ActionErrors } } }class comes very handy in resolving the first issue
of stacking messages of different category. To throw error messages of different
category use an interface to define all the different category of message like FATAL,
ERROR, WARNING, INFO etc. Then in the Action or { { { ActionForm } } } class you can
use
