In application.cfc I am defining a variable which must be available throughout a session.
<cfcomponent>
<cfset this.applicationTimeout = createTimeSpan(0,4,0,0)>
<cfset this.sessionManagement = true>
<cfset this.setClientCookies = true>
<cfset this.sessionTimeout = createTimeSpan(0,0,90,0)>
<cfset this.setdomaincookies = true>
<cfset this.myVar = "Hello">
</cfcomponent>
I tried several approaches to get the myVar in .cfm but to no avail.
Approach 1: <cfoutput>#myVar#</cfoutput>
Approach 2: <cfoutput>#session.myVar#</cfoutput>
Approach 3: <cfoutput>#application.myVar#</cfoutput>
Any help would be appreciated.
You're confusing the placement of Application.cfc's this-scoped settings with your own application-scoped variables.
Take a look at Ben Nadel's Application.cfc tutorial.
You basically want to put application.myVar in OnApplicationStart():
<cfcomponent>
<cfset this.applicationTimeout = createTimeSpan(0,4,0,0)>
<cfset this.sessionManagement = true>
<cfset this.setClientCookies = true>
<cfset this.sessionTimeout = createTimeSpan(0,0,90,0)>
<cfset this.setdomaincookies = true>
<cffunction name="OnApplicationStart">
<cfset application.myVar = "Hello">
</cffunction>
</cfcomponent>
Then you should be able to reference it in your application as application.myVar.

How do you track template path in ColdFusion?
I.E.
I have the following folder and file structure
index.cfm
<cfset ArrayAppend(request.Trace, '/')>
<cfdump var=#request.trace#>
foo
index.cfm
<cfset ArrayAppend(request.Trace, '/foo/')>
<cfinclude template='../'>
bar
index.cfm
ArrayAppend(request.Trace,'/foo/bar/')>
<cfinclude template='../'>
When I call foo/bar/index.cfm,
request.Trace equals:
'/foo/bar/'
'/foo/'
'/'
How could I do this without specifically declaring each folder name?
Have a look at:
expandPath(".")
getBaseTemplatePath()
getCurrentTemplatePath()
CGI.CF_TEMPLATE_PATH
CGI.PATH_TRANSLATED
CGI.SCRIPT_NAME
If you want the template stack trace, use this:
<cfset templateTrace = []>
<cfset tagTrace = createObject("java","java.lang.Exception").init().TagContext>
<cfloop array="#tagTrace#" index="tagInfo">
<cfset templateTrace.add(tagInfo.Template)>
</cfloop>
<cfdump var="#templateTrace#">
This will output all templates passed up to this call.
Not ideal but this worked for me.
<cfset currentFile = GetCurrentTemplatePath()>
<cfset currentDir = GetDirectoryFromPath(currentFile)>
<cfset webroot = expandPath("/")>
<cfset m_Trace = Replace(currentDir, webroot , '\')>
<cfset ArrayAppend (request.Trace, m_Trace )>
There is a new settings of Application.cfc in the coldfusion 10 which is:
this.smtpServersettings = as a structure
I can hard code the values here, but i am saving my mail settings in the database and i want to use those values here, is it possible or not to use the database settings here or not.
here is my Update:
<cfcomponent hint="File for the Website" output="false">
<cfsetting showdebugoutput="no">
<cfset this.name = "myProject1">
<cfset this.applicationTimeout = createTimeSpan(2,0,0,0)>
<cfset this.clientmanagement= "yes">
<cfset this.loginstorage = "session">
<cfset this.sessionmanagement = "yes">
<cfset this.sessiontimeout = CreateTimeSpan(0,0,40,0) />
<cfset this.setClientCookies = "yes">
<cfset this.scriptProtect = "all">
<cfset this.setDomainCookies = true>
<cfset this.customTagPaths = ExpandPath('customtags')>
<cfset this.datasource = {name="myDB"}>
<cfset this.smtpServersettings = {structur as username,password and mail settings}>
but that value needs to be through database, can you show me an example please
Yes, you should be able to set the value of the this.smtpServersettings variable from a database query. And for what it's worth, I think that setting as been available since ColdFusion 9.
All you would need to do is something like the following.
Run your query to get the values from the database
Create a new structure
Assign the three variables to that structure; server, username, and password
Assign the this.smtpServersettings variable to your new structure
Of course you will need to add some code to do something if/when your database query fails.
Update after the question was updated
Just do something like the following (pseudo code):
<cfcomponent hint="File for the Website" output="false">
<cfsetting showdebugoutput="no">
<cfset this.name = "myProject1">
<cfset this.applicationTimeout = createTimeSpan(2,0,0,0)>
<cfset this.clientmanagement= "yes">
<cfset this.loginstorage = "session">
<cfset this.sessionmanagement = "yes">
<cfset this.sessiontimeout = CreateTimeSpan(0,0,40,0) />
<cfset this.setClientCookies = "yes">
<cfset this.scriptProtect = "all">
<cfset this.setDomainCookies = true>
<cfset this.customTagPaths = ExpandPath('customtags')>
<cfset this.datasource = {name="myDB"}>
<!--- run your query here --->
<!--- check your query and do something appropriate if/when it fails --->
<cfset this.MyStructure = StructNew()>
<cfset this.MyStructure.server = this.MyQuery.ServerNameVariable>
<cfset this.MyStructure.username = this.MyQuery.UserNameVariable>
<cfset this.MyStructure.password = this.MyQuery.PasswordVariable>
<cfset this.smtpServersettings = this.MyStructure>
You also need to be aware that doing it this way will run that query on every page request. Make sure it runs fast.
I've just had a strange issue with a client's website, my live domain was using my development domains Application settings. I've not had this issue before, and removing cflock around the Application.dsn (amongst other settings) resolved the issue.
As mentioned I have a live site *www.* and development site *dev.*, my development site is in a subfolder of the live site /dev/ and has it's own Application.cfc.
My first question is, if I have variables in my Application scope in the dev folder will this overwrite the Application scope variables in the folder above? Will it consider it the same scope? If so, then this might explain what the issue and if not then I am stumped.
My second question is, how should I correct cflock application scope variables in my application.cfc? Should I be doing this at all?
Here is my Application.cfc, advice would be greatly appreciated:

Why do you change your application name based on the environment it's in? That makes no sense. The application is still the same app, irrespective of whether it's in prod, or you're staging it, or developing it.
Equally, same with the source code. You've got your dev site within your live website? How does this make any sense?
I dunno what's going on with your application variables, but they're bound to the application name (this.name), not where the Application.cfc is in the directory structure.
I suspect your zero applicationTimeout is not helping matters much here. This basically means your application never actually persists... it'll be timing out every request. This makes no sense either.
You do not need to <cflock> that code in onApplicationStart(). ColdFusion will only allow one request to run onApplicationStart(): all other requests will be queued until it's completed, by which time the application has started, so the queued requests won't even attempt to run it.
I think your problem is most likely causes by your poor application framework design, and this weird thing you're doing having dev and prod in the same source code tree (which defies all logic).
Sort your source code out, and the problem won't arise.
You can use conditional logic to set your application name.
if ( YouAreHappy and YouKnowIt ) {
This.name = "ClapYourHands";
}
else {
This.name = "StompYourFeet";
}
In real life, your if condition would be something that differented the live and test environments. cgi.http_host is a good candidate.
I have a test application structured like so:
Application.cfc
ApplicationProxy.cfc
index.cfm
sub_app/
Application.cfc
index.cfm
and I want my sub app to inherit all variables and events from the top level Application.cfc.
I have read and implemented Sean Corfield's ApplicationProxy method for extending an Application component but I can't get it to work as when I visit sub_app/index.cfm I get this error:
Could not find the ColdFusion Component or Interface ApplicationProxy.
From the error I can only guess that the application is looking in the wrong place, how do I correct this?

Best way to do is create ApplicationProxy.cfc file with all function you need to inherit and then extends in Application.cfc wherever needed. I am using this method since long time and no issue face with this approach.
Can anyone help me by suggesting a function to extract a .7z file in ColdFusion? I use ColdFusion 10 and cfscript based code. Indeed we have the cfzip tag, but it only extracts .zip and .jar files.
You can use cfexecute, which unfortunately is not availble in cfscript, to execute the 7z extractor on your server and pass through the various commands to extract the file to a place of your choosing.
Luckily for you, it seems Raymond Camden has gone into it in some detail:
