When we were using a Servlet 2.2 container we derived a class
from Action named SecureAction, which checked that the user was logged in.
what methods were used, where they were used etc..? I have the current
arrangement where I extend Action with a BaseAction, which implements
my common method (the one to be called always) and then from subclasses
of BaseAction.execute() I call the common method.
Find out what method in Action calls the execute() method, which is empty. I forget. Override that method in BaseAction, then place a call to your common method in that method. That way no Action can be called unless your common method says it can.

It is this having to manually call the common method I would like to eliminate and just have it transparently occur higher in the hierarchy.
As for your suggestion of using filters could you direct me to more information regarding that method I'm interested in exploring it.
Thanks
Then all the applications Actions would be SecureAction Children.
If struts had events then the event could be hooked instead, this is easy enough to do.
Under Servlet 2.3 filters could be used.
