Last Modified: 2013-12-24

I have a coldfusion forum application. The application is pretty old and uses application.cfm file. But now I have changed the application.cfm file to cfc which is giving me a number of variety errors? I am basically new to coldfusion and I have no Idea why I am getting these errors.

1st error was when I was trying to create a <cfapplication tag which is
<cfapplication name="EUCOM" sessionmanagement="yes"

The error I am getting is 5 >= 0  

2ns one is I have a template included in application.cfc which in also has another template called queries/qry_forum.cfm. which was working fine when I was using application.cfm file. and after I changed cfm to cfc the error here is

Could not find the included template queries/qry_forum.cfm.

Can any one please help me with this.

Thanks in advance!

Why did you chance the application.cfm to application.cfc? Application.cfm is a required file for ColdFusion applications. You cannot remove it. Your errors are probably happening because your application is looking for the application.cfm file.

Because we are using coldfusion7. And in coldfusion 7 we need application.cfc instead of cfm.

not correct...

all versions of CF can use application.cfm

application.cfc can be used with 7 & 8 but is -not- necessary

fyi ben nadel has a good tutorial on application.cfc here

as you can see it is sturctured very differently from applicition.cfm and can do a lot more however again applicition.cfm is fine to use in any version

impossible to say without knowing your app (although my first response is -why-?)

you might be able to just change

<cfset THIS.Name = "EUCOM" />
<cfset THIS.ApplicationTimeout = CreateTimeSpan( 0, 0, 20, 0 ) />
<cfset THIS.SessionManagement = true />
<cfset THIS.SetClientCookies = false />

and add queries/qry_forum.cfm to the onRequest function

hint="Fires after pre page processing is complete.">

<cfinclude template="queries/qry_forum.cfm" />
<cfreturn />

but these are just guesses... and changing may have unforeseen consequences depending on how your app is written

I have tried the above but it still giving the same errors. I will possible leave it as cfm itself. Thanks for all your help though.

as far as I'm concerned this is a "you can't" answer (or you shouldn't asit could have unforseen effects on an existing app) and points should be awarded accordingly

I did not get a possible solution for it. And what ever you have suggested I have already worked on it. So I guess it is not fair enough to award points.

And it is not a you can't answer. Because we had other applications for which we changed .cfm file to .cfc(we need to work a little bit on it). I am not able to do it since I am new to this.

my point is this...

1) some applications could easily be changed to cfc with no impact
2) if you did change there's no way to provide a simple answer with what you have provided, especially since you "are new to this" the reason you are receiving errors is precisely due to what I said "it could have unforseen effects on an existing app"
3) there's no reason to change as I answered your post "And in coldfusion 7 we need application.cfc instead of cfm." That is incorrect and my answer -corrects- your misconception

but I'm out of here...

moderators...what ever you feel is fair

Just because you have said cfc and cfm both work with coldfusion7 I need not award you points. I was looking for some kind of solution where I will be guided to change to cfc.  But all you could tell me is they both work for cf7 which is not what I was looking for and is no way close to my question. From the begining all you said was why do you want to change but not how to change. So I guess points should not be awarded.
