RE: executing statements on subsets of actions without code duplication
What is inheritancde for then:-)) Make an abstract action and have this code there... All your actions will extend this action..And bingo here you go. -Original Message- From: Rob [mailto:[EMAIL PROTECTED] Sent: Saturday, June 14, 2003 6:34 AM To: Struts Users Mailing List Subject: executing statements on subsets of actions without code duplication I have a set of statements I would like executed every time an action is executed. I would also like to only have to code these set of statements once and have them transparently executed for all actions (except for a small subset). Is there a facility in struts for doing this? Is there an example somewhere perhaps in the example application?

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. Can you explain how this was done in a little more detail, particularly 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. -Rob 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. -Rob - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
