Greetings harish,


You could actually define the global exception in Struts through the struts-config.xml

There are several attributes which you have to define in the .xml file.

The files are as follows,

type - Specifies the fully qualified class name of the exception that the handler is for.

path - The page which the config file will redirect the user to when the exception is being thrown.

key - The name of a key in the ApplicationResources.properties file that will be used to populate an ActionError object that will be passed to the page with association to the path attribute.


For example, i have an exeception class, AaronException, a key in my ApplicationResources.properties known as error.AaronException and a JSP page, aaron.jsp, the sample code configuration in struts-config.xml will goes,

 
<global-exceptions>
    <execption type="com.AaronException"
                key="error.AaronException"
               path="aaron.jsp"/>
</global-exceptions>

P.S.: You could also handle exceptions within the action-mappings...

*just my 2cents worth*
