request scope in cfc... really so bad?
Thoughts? If CFCs were EJBs, you would have external config info that you would look up using JNDI (or something, I'm not quite up to snuff on J2EE). Let's say I am careful and create well named variables like... request.cfcname.datasource = MyDatasource; request.cfcname.timeout = 300; etc, all in one file called cfcname.cfm that is included in application.cfm. Contract with the developer is you have to include cfcname.cfm in your application.cfm before calling the CFC. Am I such a bad guy? I guess worst case scenario is Macromedia decides not to support it one day, but I haven't heard anything about that. It's just such a pain if there's 10 variables in your app that are required by 10 different CFCs, passing them in as args to the constructor seems awkward.

yep, though I guess my question is really, why not use request scope, rather than how to work around it. There are probably lots of ways to do it without using request scope, but request seems like the least overhead.

RE: request scope in cfc... really so bad?
right, i guess web service is a good example. thanks for all the feedback. From: Kola Oyedeji [mailto:[EMAIL PROTECTED] Sent: Friday, June 18, 2004 10:17 AM To: CF-Talk Subject: RE: request scope in cfc... really so bad? Simon Generally its good for your cfc to be well encapsulated such that it doesn't know anything about its environment. This will make it more re-useable. Consider this - what happens if you need to call the cfc as a web service in future you've just lost that flexibility. If you have no plans to do this and you know that these variables will always be available in *every application* you write then its not a problem. But if you plan to re-use it I would pass the variables in, remember you can put them in a structure and pass them into an initialization function using attributesCollection (I think) although you loose the type checking of cfarguement.
