DispatchAction is generally used when we need to group a set
of actions. E.g. addDepartment, editDepartment,
updateDepartment, deleteDepartment. The method to be called
is identified on the basis of a parameter which can be
configured in struts-config.com (action tag). The parameter
is usually passed from the JSP and is automatically mapped
to the action parameter (defined in action tag in
struts-config.xml). Also we need to add an attribute with
name same as the parameter name to the corresponding ActionForm

If multiple actions refer to the same formbean then we
should go for DispatchAction. Yes as you said it is possible
to write in Action. But by using dispatchAction we can
simply specify the parameter name in config file.
No need to write the code in our appln
