You could create a CommonFunctionsFactory, with a method: CommonFunctions getCommonFunctionsByClass(Class)
Your action could pass itself to this call to retrieve a CommonFunctions implementation, determined by the Factory, which could look up in a properties file which implementation to create for the specified class. You wouldn't really need to have your action implement CommonFunctions. If you needed to modify the behavior of your CommonFunctionsImpl for a given action class, you could extend CommonFunctionsImpl, and then map the action class to that new subclass. -----Original Message----- From: Matthew Meyer [mailto:[EMAIL PROTECTED]] Sent: Friday, January 31, 2003 10:00 AM To: Struts Users Mailing List Subject: Re: one desing question, Revisited What you will want to is make your commonFunctions an interface. Next write a class to implement all of your common functions. Then Write your action extending Action and implementing your commonFunctions interface. Make your common funtions an instance variable of your action and then simply delegate all the commonFunction messages your action recieves to your commonFunction instance variable like so: public .... method(..., ....) { return commonFuntionInstance.method(...., ....); } Hope this helps you out...
