How you will handle exceptions in Struts ?

In Struts you can handle the exceptions in two ways : 

 

a) Declarative Exception Handling

You can either define global exception handling tags in your struts-config.xml or define the exception handling tags within <action>..</action> tag.

Example

<exception  key="database.error.duplicate" path="/UserExists.jsp" type="mybank.account.DuplicateUserException"/>

b) Programmatic Exception Handling

Here you can use try / catch block to handle the exception.
