CF9 + W2k8 Migration
We are considering moving from CF8 on 32-bit Windows 2003 to 64-bit CF9 on Windows 2008. Anyone who has experience with this, if you could please give me your feedback on any issues you may have dealt with, hurdles you crossed, and gotchas that slowed your progress. -- Steve Cutter Blades Adobe Community Professional - ColdFusion Adobe Certified Professional Advanced Macromedia ColdFusion MX 7 Developer Co-Author of Learning Ext JS http://www.packtpub.com/learning-ext-js/book _ http://blog.cutterscrossing.com ~| Want to reach the ColdFusion community with something they want?

Easy application question
I think I misunderstand how to use application.cfm files. I have a application.cfm file on the root and I set a group of session variables. I have a folder off the root named products with an application.cfm file in it. It was my understanding that the root application.cfm would take precedence to the subfolder's application.cfm and could share variables to the application.cfm like it could any page in that folder. But when I call a variable in the sub application.cfm file to the higher level application.cfm, I get variable is undefined error. Is that just not possible to share variables among application.cfm files even if they are hierarchically below a higher application.cfm file or am I doing something else wrong? ~| Want to reach the ColdFusion community with something they want?

Make sure both Application.cfm files have the same name in the cfapplication tag. thanks, eric cobb http://www.cfgears.com Brian Bradley wrote: I think I misunderstand how to use application.cfm files.

Re: Easy application question
Only a single Application.cfm file (note the capital 'A') will be run for a single request. CF will look up the directory tree until it finds one, but it will stop it's search at the first one encountered. If you want to chain Application.cfm files as you propose, simply use CFINCLUDE to grab the parent one: cfinclude template=../Application.cfm / Unfortunately, Application.cfc is becoming a requirement for building CF applications, so you should switch to that. It has a host of problems, but it's also the only way to get certain functionality with CF (ORM, default datasource, code-based mappings, etc.). Hopefully Adobe will change that, but it seems unlikely. Railo, by contrast, lets you use the full functionality without forcing you into Application.cfc and all the problems it provides. cheers, barneyb On Mon, Apr 12, 2010 at 7:01 AM, Brian Bradley bbrad...@plrb.org wrote: I think I misunderstand how to use application.cfm files.

Re: Easy application question
You have it backwards. The sub-directory Application.cfm takes precedent and the higher Application.cfm is not used by default. But there is nothing preventing you to tell the sub-directory Application.cfm by using a cfinclude template=path/to/root/Application.cfm ~| Want to reach the ColdFusion community with something they want?

Re: Easy application question
Barney, Not to pick a fight, but what problems do you see with using Application.cfc? I, personally, find it to be a much better solution, so I am curious about your misgivings...

Re: Easy application question
The primary issue is that it couples your persistence layer (default datasource and ORM) your business layer (mappings) and your front controller (events) into a very inflexible one-to-one-to-one structure. You can't have multiple frontends for a single ORM persistence layer, for example. You also can't have a single frontend backed by mutliple Hibernate SessionFactories. Then there are some implementation problems, the biggest one being that you don't have access to the application scope when you're defining the this.XXX variables. That means if you're setting them dynamically you can't rely on an application-scope cache, you have to store your per-application configuration in the server scope. But there isn't any sort of event for that, so you end up jumping through all kinds of hoops to deal with the arcane timing of the Application.cfc psuedoconstructor because that's the ONLY place you can define settings. It's enormously better with the CFAPPLICATION tag, because you can run that anywhere you want. Even better, Railo lets you run the CFAPPLICATION tag multiple times, so you can run it once to get your application scope, and then run it again to set up mappings/default dsn/whatever. That's really powerful. So it's not really Application.cfc itself, it's more that Adobe has piggybacked so much functionality on top of Application.cfc that really doesn't belong there. The event handler structure is quite beneficial, don't get me wrong, but they've tried to make Application.cfc the be all/end all place for everything, and it really paints you into a corner with complex applications/deployments. Application refers to a lot of different things in the Adobe parlance, and they've squished them all into a single container. cheers, barneyb On Mon, Apr 12, 2010 at 8:35 AM, Cutter (ColdFusion) cold.fus...@cutterscrossing.com wrote: Barney, Not to pick a fight, but what problems do you see with using Application.cfc?

Bind / CFC Question
I am fairly new to CFCs and binding and have only used query returns with 1 column. I was wondering how to bind to a cfinput with a certain column when my query is selecting * from a table.

Anyone who has experience with this, if you could please give me your feedback on any issues you may have dealt with, hurdles you crossed, and gotchas that slowed your progress. We have done just that and it was almost painless. Code all ran fine, but we ran into some bumps with payment gateways and the like as 64bit CF won't run 32 bit CFX tags. In every case there was a different version or a move to java-based gateway objects that fixed the problem. 2008 is a breeze to set up, add the IIS bits in roles/features in the Server Manager, the firewall should adjust itself for http and CF installs just fine over it all. Depending on your intentions for email sending you will probably have to open up SMTP outbound in the firewall. Of all of the hundreds of upwards migration we have done over the years this was the easiest... -- Yours, Kym Kovan mbcomms.net.au ~| Want to reach the ColdFusion community with something they want?

Re: CF9 + W2k8 Migration
I also just migrated a large eTraning app from CF8 32bit to CF9 64bit Win2k3 - Win 2k8. It was painless. The CF9 installer works really well with IIS 7.0 and 7.5 now. We only had a few issues where local.something was treated differently under cf9 but that was fixed in about 2 mins. Perfomance has been great.
