Why isn't ActionsErrors throwable?
Hello,
I've got a design question concerning the design of
action classes and action class inheritance. I am
trying to implement a reusable method in an action
class. This method should be in a class named
MyActionBase:
protected MyBusinessObject doSomething(...) throws
ActionErrors
The question is: Why doesn't ActionErrors extends
Throwable? Does it make sense to make a change in the
framework class org.apache.struts.action.ActionErrors
and make it throwable?
Thanks,
Tillmann

You are right, ActionErrors is a container, but
ActionError is sth. like an error class with a error
message in it.
I was just a little bit confused about the naming
because in java.lang.* every *Error-class extends
Throwable.
Cu,

essentially ActionErrors is a message container
more than an exception. i think the name reflects
this as well... it is not called ActionException.

Because exceptions are slow, and can only handle one error
at a time. The design as it is, allows for multiple action
errors to be returned to a page for display.
Exceptions should be for catastrophic errors that cause
the system to barf. Having a blank password doesn't really
fit within that framework.
