So you probably want another CFC (call it a "service" component), perhaps called CustomerService.cfc. In there you may have a method called "exportCustomerData," which might possibly take some arguments, such as a Customer Type, a date range, or other filtering mechanisms. The CustomerService would call a method on CustomerGateway that retrieves the query data. While the gateway *could* build the struct, you generally want to leave that sort of work to another component, using the gateway strictly for database interaction. So perhaps the gateway's method is just "GetAll" (or whatever's appropriate, depending on whether you need to apply filters in the query), and you build the struct (or array, or just leave it as a query, depending on what you need), in the CustomerService. Then the CustomerService calls the Export.cfc's method, and does whatever's necessary - saving the spreadsheet, returning it to the browser, whatever. Unless you have a reason to persist the query data from request to request, you don't want or need to place it in the session scope. So: 1. Request calls method on CustomerService, optionally with filter data. 2. CustomerService calls CustomerGateway to get data, optionally with filter. 3. CustomerService manipulates data into what array/structure/etc. you want (this could even be done by some sort of utility cfc) 4. CustomerService call Export.exportToExcel(data), passing in the data it has manipulated. 5. CustomerService completes its action by returning the filename of the spreadsheet, or whatever's appropriate to your needs. >From there on, it kinda depends on what you want to do with the spreadsheet. -- Thanks, Tom Tom McNeer MediumCool http://www.mediumcool.com 1735 Johnson Road NE Atlanta, GA 30306 404.589.0560 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:340579 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
