CFLock Challenge with CFObject in Application.cfc

I occasionally get a cflock error when running an application
in the morning. I moved several cfobject lines into the
application.cfc onApplicationStart method. Some of the methods in
the objects use cflock to read a session variable.
Here is the error:
Cannot lock session scope. Cannot use cflock to lock the
application or session shared scopes without these scopes being
established through the use of the cfapplication tag. To use the
session scope you need to enable session management. Application
and/or Session variables must also be enabled in the ColdFusion
Administrator. <br>The error occurred on line 5.

Have you ensured the Application variables and Session
variables are enabled in the Coldfusion Administrator?.
If so, try replacing your <cfscript> block with normal
<cfset> statements and see if it is working..

Problems with cflogin and application.cfc

I am creating a reporting site for my clients, and for the
most part everything works great. That is until the site is viewed
with Safari 3. When I first look at it, the login page displays
fine. If I do log in successfully, Safari still displays the login
form at the top of the page. It also creates frames that are not
intended to be there. If the login fails, then it displays multiple
login forms. I've checked the site in both I.E. and FireFox, and
they appear correctly. Has anyone ever dealt with this?

post the code - i suspect it is not just your login script at
play there...
a link to a sample page would be very helpful, too.

Moving to CF10, Need help with Application.cfc

I've been googling about how to work with Application.cfc since last week but I still have some questions and I can't find the answers.
My application is under the root (in unix) and there are many subfolders underneath it. Each sub-folder is hosting a different web application.
From what I read, I can create 1 root Application.cfc and then on subsequent sub-folder, when I need to have another Application.cfc on that level, I can create ProxyApplication (see below) and then create a sub-folder level Applicatin.cfc
So, when I set an application.DSN on my root Application.cfc, using proxyApplication I don't have to reset this dsn again in my sub folder level Application.cfc
Since my loginform.cfm and loginaction.cfm is right under root directory too, I also set OnsessionStart in the root Application.cfc to handle user login. Then this means, I don't have to reset session variable again anywhere because session.username, etc has been set on the highest level.
Is this correct?
In addition, Am I correct when I do the following:
1. Since I have root level and sub-folder level Application.cfc, I should set this.name with a different name, am I right?
    On the root Application.cfc I set this.name = "StudentServices" because this represent the global application
    On the sub-folder level's Application.cfc, I set this.name to "StudentServices_stdLoad" becaus this sub-folder only handle student load application.
2. On the root Application.cfc, I set the DSN to the application scope. So on the sub-folder level Application.cfc I can check if a particular db is working or not
    because as awhole, in the global sense, this web application uses more than one Databases. Each sub-folder may use a database that is dfferent than the other sub folder.
Am I doing the right thing? Please advice
Below is example of what I have, Thank you!
I created a root Application.cfc under the root directory:
<CFCOMPONENT displayname="Application" output="true" hint="My Root Application component">
       <cfset THIS.Name = "StudentServices" />    <cfset THIS.ApplicationTimeout = CreateTimeSpan(0,0,30,0) />    <cfset THIS.SessionManagement = true />    <cfset THIS.SetClientCookies = false />
       <cffunction name="OnApplicationStart" access="public" returntype="boolean" output="false">
   <cfset application.MainDSN = "DSN1">
   <cfset application.ReportDSN = "DSN2">

</cffunction>
<cffunction name="onApplicationEnd" output="false">
     <cfargument name="applicationScope" required="true"> </cffunction>
<cffunction name="onSessionEnd">
</CFCOMPONENT>
Then, in this root directory I also created a ProxyApplication:

<cfcomponent name="ApplicationProxy" extends="AdvancementServices.Application">
</cfcomponent>
Then in the Sub-Directory, I can create a sub-folder level Application.cfc extending the root Application.cfc:
<CFCOMPONENT displayname="Application" extends="ApplicationProxy">
    
    <cfset THIS.Name = "StudentServices_stdLoad"/>
    <cfset THIS.ApplicationTimeout = CreateTimeSpan(0,0,30,0) />
    <cfset THIS.SessionManagement = true/>
    <cfset THIS.SetClientCookies = false/>
    <cffunction name="OnApplicationStart" access="public" returntype="boolean" output="false">

       <cfquery name="TestMain_DSN" datasource="#application.MainDSN#" maxrows="2">

        <cfcatch type="database">
          <cflog file="#this.name#" type="error" text="Main DSN is not available. message: #cfcatch.message# Detail: #cfcatch.detail# Native Error: #cfcatch.NativeErrorCode#" >

         <cfreturn false>
       </cfcatch>
     </cftry>
     <cflog file="#this.name#" type="Information" text="Application #this.name# Started">
     <cfreturn true/>
   </cffunction>
</CFCOMPONENT>
    <cfargument name = "SessionScope" required=true/>     <cfargument name = "AppScope" required=true/>
</cffunction>
<cffunction name="OnSessionStart" access="public" returntype="void" output="false">
<CFSET session.UserGroup = ""/>
<CFSET session.UserName = ""/>

<cfreturn/>
</cffunction>

OK. It sounds to me like you really shouldn't be using a single root Application.cfc at all, if all you want to do is share some settings between your "sub-applications". I would look at storing the common settings in an external file that all of the applications can read in. The simplest way is to put the settings in a .CFM file somwhere outside of the web root (so it is not directly web accessible) and load it with <cfinclude> tag into the OnApplicationStart() method of each sub-application's App.cfc. That .CFM file can be as simple as:
<cfset application.myCustomSetting = "blahblah">
<cfset application.myOtherSetting = "foo">
Alternatively, you can look at using a config file like this Ray Camden blog post suggests, and use the GetProfileSection(), GetProfileString(), and SetProfileString() functions as needed within OnApplicationStart(). You could even put ALL of your settings in
A third option is to store your settings in an XML file or in JSON format in a text file. You could then write code to read in the XML file, and use something like xml2struct.cfc to convert the XML into a struct, then append the struct to your application scope. If you go the JSON route, then just read in the JSON file and use DeserializeJSON() to convert it into a struct, and append it to the application scope.
What I think is probably the best approach is to use a community-supported MVC framework like FW/1 or ColdBox (maybe you already are, I don't think you've said so though). One of the many advantages to doing so is that they have built-in "environment" support that can be used to configure common settings, depending on your environment (dev/qa/production). You would handle reading in your external settings through the "environment" mechanism.
One other thing to think about: your login mechanism. I think you want to use one set of login tools that is shared by all of the "sub-applications". You can do this also by putting the login/authentication-related code somewhere outside the webroot of your applications, and then either set up a mapping to that location in CF Admin, or set an application-specific mapping in your various App.cfc files. That way all the "sub-applications" share a common set of code for the login process. I don't know how your login process works (do all users go to the same login page then get redirected into their relevant "sub-application", or does each "sub-application" have a discrete login page that utilizes common back-end processes to authenticate and redirect), so you'll have to judge how that is best accomplished.
Hopefully this gives you some useful ideas.

Cfobject / cfinvoke problem in my application.cfc

Hello;
I am trying to use cfobject in my onsessionstart function in my application.cfc file. The cfobject is another application.cfc file I have in a sub directory in the web site, it runs the shopping cart. I am not firing this off properly and I was hoping someone could help me fix my code so it will operate properly.This is my invoke statement:
<cfobject name="SESSION.myShoppingCart" component="ShoppingCart">
<cfinvoke component="#SESSION.myShoppingCart#" method="getShoppingCart">
This is my whole argument statement for on session start:
<cffunction name="onSessionStart" returntype="any" output="true">
<cfset SESSION.created = now()> 
<cfobject name="SESSION.myShoppingCart" component="ShoppingCart">
<cfinvoke component="#SESSION.myShoppingCart#" method="getShoppingCart">
</cffunction>
this is my error:
Context validation error for tag cffunction.
The end tag </cffunction> encountered on line 80 at column 11 requires a matching start tag.
The error occurred in C:\website\Application.cfc: line 28
26 : <cffunction name="onSessionStart" returntype="any" output="true">
27 : <cfset SESSION.created = now()>
28 : <cfobject name="SESSION.myShoppingCart" component="ShoppingCart">
29 : <cfinvoke component="#SESSION.myShoppingCart#" method="getShoppingCart">
Can anyone help me? What do I need to do to set off my shopping cart functions on the cfc I am trying to invoke?
Thank You
CFmonger

this is what I am supposed to put in the on sessionstart function:
<cfobject name="SESSION.myShoppingCart" component="ShoppingCart">
But this throws the same error. I am reading this off of instructions from a book. Obviously the book is wrong. Is there a way to make that cfobject statement work? I don't want a return variable. I want the ShoppingCart.cfc that resides in the sub directory /donation/ShoppingCart.cfc to go into client memory, I don't need a return value, I need the shoppong cart application portion fired when they hit the web site, creating a "shopping cart" in session / client variables.
How would I do that using this tag? Thanks.

Issues with data returned on application.cfc onRequeststart

I have a shopping cart that works from main code with VD on IIS.
So all the code is places in one directory, and for each store I create a Virtual directory on the IIS
so a store link will look like this :
www.shoppingcart.com/store/XXXXX
when the xxx is the prefix of that store.
in the application.cfc ONREQUERSTSTART I take the last part of the URL and match it with the PREFIX I in the list of stores on the DB.
to get the prefix I do this :
<cfset request.store.prefix = "#listgetat(cgi.SCRIPT_NAME,listlen(cgi.SCRIPT_NAME,'/')-1,'/')#">
Then to get the right store info I used to do this :
<cfset qreadStoreInfo = application.cfc.StoreDetails.read(filterStorePrefix request.store. prefix)>
It all worked well (for over 4yrs) till about 2-3 moths ago (or at least then one of the client complained) when we start seeing the WRONG output of store info, like stores were "mixed" some how – totally randomly.
After following it for a few days I noted that the query that is returned from the CFC is for the wrong store.
At first I thought it’s the request.store.prefix not "stored" by the time I get to the query line so I changed this :
<cfset qreadStoreInfo = application.cfc.StoreDetails.read(filterStorePrefix= "#listgetat(cgi.SCRIPT_NAME,listlen(cgi.SCRIPT_NAME,'/')-1,'/')#")>
Yet I still get the wrong value back from the Query, and when looking at the Query I can see that the VALUE been sent in is wrong, even that I know for sure that I sent in the right value, since in the email I do an out put of the info on the page.
Did any one encountered any thing like this before ?
Any leads on how to maybe start handling ?
Is there a way that if the client is looking at 2 site at the same time thus queries can get "mixed", even that they are done on the ONREQUEST part of the application.cfc (IE each page should be processed on its own)

That wont get you the prefix, I'm afraid. You want the last list element. To get it, you could use
<cfset request.store.prefix = listgetat(cgi.SCRIPT_NAME,listlen(cgi.SCRIPT_NAME,'/'),'/')>
or, even better,
<cfset request.store.prefix = listLast(cgi.SCRIPT_NAME,'/')>

Need help with application.cfc

Here is what I am trying to do. I have a login page, and when
a user logs in it verifies their credentials. If everything is good
it sets a session variable called #session.username#. What I want
to happen is at that point update a database field to set the user
logged on status to 1. Everything to that point is fine. I am
getting stuck at updating the databse when the users session ends.
Before the session ends I would like to update the db field for the
user and set the logged on status to 0.
I haven't used application.cfc before. I have been messing
around but nothing is working. Here is a copy of my application.cfc
file. If anyone has any idea on how to run a query onsessionend and
update a db I would appreciate it.

Take a peak at the documentation. It describes all the ins

you have to do the same thing with application variables as
session
variables. The hint being that you are also defining an
appScope
argument as well as the sessionScope argument, there is a
reason for this.

Usage
Use this method for any clean-up activities when the session
ends. A
session ends when the session is inactive for the session
time-out
period or, if using J2EE sessions, the user closes the
browser. You can,
for example, save session-related data, such as shopping cart
contents
or whether the user has not completed an order, in a
database, or do any
other required processing based on the users status.
You might also
want to log the end of the session, or other session related
information, to a file for diagnostic use.
If you call this method explicitly, ColdFusion does not end
the session;
it does execute the method code, but does not lock the
Session.
You cannot use this method to display data on a user page,
because it is
not associated with a request.
You can access shared scope variables as follows:
You must use the SessionScope parameter to access the Session
scope. You
cannot reference the Session scope directly; for example, use
Arguments.SessionScope.myVariable, not Session.myVariable.
You must use the ApplicationScope parameter to access the
Application
scope. You cannot reference the Application scope directly;
for example,
use Arguments.ApplicationScope.myVariable, not
Application.myVariable.
Use a named lock when you reference variables in the
Application scope,
as shown in the example.
You can access the Server scope directly; for example,
Server.myVariable.
You cannot access the Request scope.
Sessions do not end, and the onSessionEnd method is not
called when an
application ends. The onSessionEnd does not execute if there
is no
active application, however.

Where is the best place to set the path with Application.cfc?

Hi!
When I used Application.cfm, I set many path variables here so I don't have to keep writing a full path on many of the templates repeatedly.
So I did:
<CFSET FileArchives = "/space/users/www/FileArchives/#session.Groups#/">
<CFSET GoodFiles = "/space/users/www/GoodFiles/#session.usergroup#/">
etc...
Later on I only need to refer it as: #FileArchives# in the codes instead of a full path name.
Now that I'm using Application.cfc can I also do the same thing???? should I do it within OnApplicationStart function? am I doing it correctly? (see below)
     <cffunction name="onApplicationStart" returnType="boolean" output="false">
           <cfset application.dsn = "EMBB">
          <CFSET application.FileArchives = "/space/users/www/FileArchives/#session.Groups#/">
          <CFSET application.GoodFiles = "/space/users/www/GoodFiles/#session.usergroup#/">
         <cfreturn true />
     </cffunction>

Indeed. Wading through this lot - http://adamcameroncoldfusion.blogspot.co.uk/2012/08/more-on-applicationcfc-when-things-run .html - might be helpful for the OP to get a handle on when things run, and when things become available.
But the session scope is not available in onApplicationStart().

What's wrong with my Application.cfc file

I've decided to convert an old app from using Application.cfm to Application.cfc, mainly because I want to use onRequestStart and the like, and I can't get them to initialize in Application.cfm.
But for some reason, this Application.cfc file causes my pages to come up blank. I can't for the life of me figure out why, since it's copied from an app that works perfectly fine.

What have I done wrong?

What is in the two templates you are including inside your onRequest() function? Do they actually output any content?
You don't have the actual requested page being included. You need to add an argument to the top of the function to receive the requested page:
<cfargument name="TargetPage" type="string" required="true">
Then you need to add another <cfinclude> to include that page:
<cfinclude template="#arguments.TargetPage#" />
You'll have to figure out if that include should come before or after your existing includes.

Work around for Application.cfc

I have an Application.cfc file that outputs a header and footer page for every request. That works wonderful but if I try to open a page that is doing a <cfgrid> using a CFC file than I get an error of "Error invoking CFC /GATS/CFC/purchaseOrder.cfc : Internal Server Error [Enable debugging by adding 'cfdebug' to your URL parameters to see more information]" when opening the page.
Commenting out the header/footer include in the Application.cfc file lets the <cfgrid> populate with the CFC file. Is there a fix or work around for this?

I found this on the web:
That error is due to our application.cfm having a single HTML comment at the
start of the file. Apparently if your Application.cfm or Application.cfc file
outputs ANYTHING, binds to CFCs with AJAX (via HTML CFGRID or CFAJAXPROXY, for
example) do not work. The CFC will be called, but the data from it will never
"flow" into the CFGRID. Removing the comment from the Application.cfm file took
care of our CFGRID issue.
This there a way to have an Application.cfc file that displays a header and footer for every page and have and
have a page have a <cfgrid> in it?

BKBK,
I created the examples you posted and commenting out the header/footer lines in my Application.cfc displayed the cfgrid results (updating the query to a table I had). Running the same example code with the header/footer included in the Application.cfc would not show the cfgrid results.
I attached the Application.cfc file for review.
Couldn't attach the file.

Which to use application.cfm or application.cfc?

Hi,
Just a general question, i have been using application.cfm
for my applications so far. I came across a tag that would be used
under application.cfc, but i tried putting both templates together
in one application and boom, an error showed up.
So, which is better to use with most of the applications
application.cfm or .cfc?
Thanks for any help!

It's actually a bit easier to use session and application
scope variables with Application.cfc, I think.
Application.cfc has methods for specific "events" or states:
onApplicationStart() -- where to load application variables,
security logic, etc.
onSessionStart() -- initialize session varialbes, etc.
onRequestStart() -- runs at the start of each page request
onRequestEnd()
onSessionEnd()
onApplicationEnd()
onError() -- very nice place to get some good
Application-wide error handling code in place
onRequest() -- be sure to read the notes on this
method...it's a bit different.
Check out the MX7 reference page for Application.cfc:
http://livedocs.adobe.com/coldfusion/7/htmldocs/wwhelp/wwhimpl/common/html/wwhelp.htm?cont ext=ColdFusion_Documentation&file=00000692.htm

SetEncoding() and application.cfc

Is this a bug, or I just didn't understand the way it is
supposed to work?
I just finished determining that if one puts a <cfset
setEncoding("form","encodingType")> in the
psudo-consructor (after the
<cfcomponent...> but before any <cffunction...)
tags) of Application.cfc
one will always receive empty form structures on an action
page.
When I tried moving said setEncoding() line to the
onRequestStart()
function. All was well? Is there a reason for this I do not
understand
with my very limited knowledge of page encoding?

Application.cfc is event-driven, all its methods being
events. I think
you should expect to be in uncharted territory if you use any
method
different from the given list
First, you can augment the functions of Applicaiton.cfc if
you so
desire, it is just that these functions will never be called
by any
event. But there is nothing wrong with them being called by
functions
called as a result of one of the defined events.
Secondly, I was not doing this.
Relevant parts of my Application.cfc file:
<cfcomponent output="no">
<cfprocessingdirective pageencoding="windows-1252" />
<cfset variables.coding = "windows-1252">

<cfset setEncoding("form",variables.coding)>
<cfset setEncoding("url",variables.coding)>
<cffunction name="onRequestStart" output="false">
<cfargument name="requestname" required="yes">

<cfset setEncoding("form",variables.coding)>
<cfset setEncoding("url",variables.coding)>
</cffunction>
</cfcomponent>

Lost on application.cfc

Hi all,
I've used application.cfm for ages on our site (now in sustainment) and we have been moved to a new server using CF9. Our server dudes have "per application" settings in place where I can map my custom tag directory (works fine) but when I use application.cfc, I begin crashing on all my pages that use relative pathing.
For example, the first thing the application does is query an Oracle table to get security settings. This is located off the root in a folder (oddly enough) called Security. That folder has a subdirectory called queries. I bomb with an error saying that "<cfinclude template="queries/user_role_select.cfm">" is invalid and it cannot find the noted cfm file and that I have to set up mappings in my application.cfc file.
Does this mean that I have to provide mappings for every directory and subdirectory under my root folder? Surely not! If so, how can this be done and how would I use that mapping in my cfincludes? I'm really getting started with the cfc files late in the game so any guidance and direction is GREATLY appreciated.
Thanks in advance!

What is the EXACT error message? Don't paraphrase it, copy and paste it from the screen.
Also: what is the full file system path to the file with the <cfinclude> in it, and the file system path to queries/user_role_select.cfm?
What mappings have you set in CFAdmin and in your Application.cfc pseudo constructor? Ditto custom tag paths (although the latter ought not be relevant here)?

Updating application to use Application.cfc

I have an application that is using the older style
application.cfm for setting up configuration varibles like DSN and
what not. Of course this way i can just use the varibles as is like
#dsn#.
I am wanting to change my application over to utilize
Application.cfc instead now. It seems to set up my DSN efficiently
i would set this varible up in the onApplicationStart or
onRequestStart. Either way I have to now state my varibles as
#application.dsn# to make them work now.
Is there anyway around this so I dont have to change hundreds
of varibles names!

Implement
<cffunction name="onRequest">
<cfargument name = "targetPage" type="String"
required=true/>
<cfsavecontent variable="content">
<cfinclude template="#Arguments.targetPage#">
</cfsavecontent>
<cfoutput>#content#</cfoutput> 
</cffunction>
You can then change gear in onRequestStart with:
<cfset dsn = application.dsn>
In fact, you can forget about application.dsn and do the
following in onRequestStart:
<cfset dsn = "myDSN">

Am i supposed to invoke application.cfc?

My website is always on the index.cfm page, do I just throw a <cfinvoke> tag in there to call the application.cfc? Am I supposed to name it with an uppercase A (Application.cfc)?

Yes.

No. Coldfusion instantiates Application.cfc automatically.

Application.cfc versus application.cfm

HI I have application.cfc and applicaiton.cfm in one folder. I defined same global varibales in both files with different values. I am using same global variables in my cfml files. When I call my cfml page which values will dispaly in my page?

Daverms is right. But Owain and Adam are also right - you should test these things to find out. It's a much better way to learn, it actually takes less time than to wait for an answer, and you're more likely to remember the answer.
