Application.cfc

Below is a section of my application.cfc.
The page loads ok but when I make changes to
the applcication variables (e.g Application.var1="var1Name";
) no changes take place when the page reloads on the browser.
I have to restart the ColdFusion service for this changes to
be implementated. For example if I cahnge the value of
Application.var1 to "three". I will need to restart the service for
this to be implemented.
Any ides ?
<cfcomponent>

createTimeSpan(0,0,20,0)>
<cfset This.clientmanagement= "yes">
<cfset This.loginstorage = "session">
<cfset This.Sessionmanagement = "yes">
<cfset This.Sessiontimeout = createTimeSpan(0,0,20,0)>
<cfset This.SetClientCookies = "yes">
<cfset This.SetDomainCookies = "no">
<cfset This.ScriptProtect = "all">
<cfset This.SiteMaintenance="false">
<cfset This.thePath = "

<cffunction name="onApplicationStart">
<cfscript>
//set your app vars for the application
Application.var1="var1Name";
Application.var2 = "var2Name";
Application.var3="var3Name";
</cfscript>
<cftry>
</cffunction>
</cfcomponent>

Any ideas?
Yup. It is working exactly like it is supposed to. Reloading
the page
in the browser is not a new application start. An application
start, by
definition, only happens once after any previous application
has timed
out or been stopped, such as stopping the ColdFusion service.
Two ideas to consider. If you are resetting variables, should
they be
application variables. Maybe you are really dealing with data
that
should be session variables.
Second, most of us write some kind of refresh trigger into
our apps.
What I usually do is in onRequestStart of code something like
this.
<cfif structKeyExists(ur,"refresh")>
<cfscript>
onApplicationStart();
</cfscript>
</cfif>
This will call the onApplicationStart function if the request
contains a
refesh variable.

  • Tracking users in the Application.cfc, please help

    Hello;
    I wrote a small tracking system for my web site. I am trying
    to upfrade it to work in CF 8. Here is what I am doing.
    I had this code on the index.cfm page of my site. I am
    attempting to move it to the Application.cfc file. When I do, it
    registers in the DB every time the user hits a page or clicks a
    link. I don't want it to do that. I do want it to tell me when they
    hit the site, and if I can what page they came in on.
    Here is my code:
    <cfquery name="tracking" datasource="my-DB"
    dbtype="ODBC">
    INSERT INTO tracking (REMOTE_ADDR, HTTP_USER_AGENT,
    TRACK_DATE, PageID)
    VALUES('#REMOTE_ADDR#', '#HTTP_USER_AGENT#',
    #CreateOdbcDateTime(now())#)
    </cfquery>
    My pageID is where I want the information on what page the
    user came in on to go.
    I placed teh query inside a session function code, but it
    doesn't work at all right now, I need to limit the hits counted by
    the Application.cfm, if I place it inside the area of the app that
    is for global variables, it adds info to the DB everytime they
    click a link and I don't want that. As for the entry page of the
    user, I am trying to make it so if someone enters the site lets say
    on the about.cfm page, that is added to the db and so on. Is this
    possible? If so how would I do that?

    I did a dump and got it to error out, so it is recognizing
    the session, but it doesn't add any info to the DB. I also had to
    change it, I had it like this:
    <cffunction name="onSessionStart" returntype="query"
    output="true">
    <cfquery name="tracking" datasource="my-db"
    dbtype="ODBC">
    INSERT INTO tracking (REMOTE_ADDR, HTTP_USER_AGENT,
    TRACK_DATE)
    VALUES('#REMOTE_ADDR#', '#HTTP_USER_AGENT#',
    #CreateOdbcDateTime(now())#)
    </cfquery>
    </cffunction>
    Changed it to this:
    <cffunction name="onSessionStart" returntype="any"
    output="true">
    <cfquery name="tracking" datasource="creative"
    dbtype="ODBC">
    INSERT INTO tracking (REMOTE_ADDR, HTTP_USER_AGENT,
    TRACK_DATE)
    VALUES('#REMOTE_ADDR#', '#HTTP_USER_AGENT#',
    #CreateOdbcDateTime(now())#)
    </cfquery>
    </cffunction>
    it was erroring on the query attribute before in the session
    function. Even that change didn't get it to work properly.

  • 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">
       <!--- Set up the application --->    <cfset THIS.Name = "StudentServices" />    <cfset THIS.ApplicationTimeout = CreateTimeSpan(0,0,30,0) />    <cfset THIS.SessionManagement = true />    <cfset THIS.SetClientCookies = false />

         <cfargument name="applicationScope" required="true">  </cffunction>

     <cfcomponent name="ApplicationProxy" extends="AdvancementServices.Application">

    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.

  • 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!
    Syed

    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:

  • 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">
    <!--- placing these setEncoding() functions here, in the
    psudo
    constructor, failed. This cause the form structure to always
    be empty. --->
    <cfset setEncoding("form",variables.coding)>
    <cfset setEncoding("url",variables.coding)>
    <cffunction name="onRequestStart" output="false">
    <cfargument name="requestname" required="yes">
    <!--- placing these setEncoding() functions here, in the
    onRequestStart, works fine. --->
    <cfset setEncoding("form",variables.coding)>
    <cfset setEncoding("url",variables.coding)>
    </cffunction>

  • 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().

    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.

  • 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)?

  • Application.cfc and UDFs

    I have some UDFs that i want to make available to every page
    in my site woudl i just drop the code for those UDFs inside the
    onRequestStart method of application.cfc?

    Probably the simplest approach for you is to put those UDFs
    in some
    cfm file and then include that into onRequest():
    <cffunction name="onRequest">
    <cfargument name="targetPage"/>
    <cfinclude template="myudfs.cfm" />
    <cfinclude template="#arguments.targetPage#" />
    </cffunction>
    Note: you must include the target page - onRequest() assumes
    you are
    taking full responsibility for the request.
    Only when you use onRequest() will the VARIABLES scope of
    Application.cfc be accessible inside your top-level page
    (arguments.targetPage).
    Note: if you use Flash Remoting, Web Services or direct AJAX
    CFC
    calls, you cannot use onRequest() directly (because it
    intercepts the
    result). Read the chapter on Application.cfc in the
    ColdFusion
    Developer's Guide (it's really very good reading!). You might
    also
    want to read this blog entry:

  • 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.
    <cfcomponent>
        <cfset this.name = "myapp">
        <cfset this.sessionManagement = true>
        <cfset this.sessionTimeout = CreateTimeSpan(0,2,0,0)>
        <cfset this.loginStorage="session">
        <cfset this.scriptProtect = true>
        <cfset this.setclientcookies = false>
        <cffunction name="onApplicationStart">
            <cfset application.dsource = "mydsn">
            <cfset application.appid = "123456">
            <cfset application.appname = "myappname">
        </cffunction>   
        <cffunction name="onSessionStart">
            <cfparam name="session.trackingno" default="0">
            <cfparam name="session.emailaddr" default="">
            <cfparam name="session.newitem" default="1">

            <cfparam name="session.rights" default="">
            <cfparam name="session.userid" default="">
            <cfparam name="session.sauth" default="">
            <cfparam name="session.creds" default="">
        </cffunction>

    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.

  • 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> <!---
    requested page content --->
    </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)?

    Am I supposed to name it with an uppercase A (Application.cfc)?
    Yes.
    My website is always on the index.cfm page, do I just throw a <cfinvoke> tag in there to call the application.cfc?
    No. Coldfusion instantiates Application.cfc automatically.

  • 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?

      <cfgridcolumn name="ID" header="ID" display="yes">
      <cfgridcolumn name="vendor_name" header="Name" display="yes">
    </cfgrid>
    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.

  • 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.

  • CFGrid and Application.cfc - bug??

    I don't understand what is happening here.
    If I open the cfgrid.cfm page without the Application.cfc
    file it works fine.
    With the application.cfc file the grid does not populate.
    If I comment out the cfajaximport, onrequeststart, onrequest
    and onrequestend it works fine.

    the best i could find was comment #8 by Scott Jibben here:
    http://www.forta.com/blog/index.cfm/2007/6/4/ColdFusion-Ajax-Tutorial-4-Partial-Page-Updat es
    i was apparently remembering things wrong and it is
    onRequestEnd method
    that seems to be the culprit... though i suppose depending on
    what you
    have in onRequest method may make it a collaborator too... i
    know for
    sure onRequest interferes with flash remoting and invoking
    cfc's as
    webservice...
    but why do you have <cfajaximport ...> tag in your
    Application.cfc???
    iirc, that is not a good practice - you should use it on your
    .cfm page
    in general, and in your particular case i don't think you
    need it at all.
