    copied!<p>I have trouble with setting mappings in Application.cfc We have diverent Server (dev,QS,prod) Each with a little different Pathes. I want to set serverspecific pathes and variables via configuration file. On ApplicationStart you read the ini file and setup your system. <a href="http://www.raymondcamden.com/index.cfm/2005/8/26/ColdFusion-101-Config-Files-AGoGo" rel="nofollow">http://www.raymondcamden.com/index.cfm/2005/8/26/ColdFusion-101-Config-Files-AGoGo</a> This works fine. </p> <p>Normaly you set mappings in Applcation.cfc like this:</p> <pre><code>&lt;!--- in Application.cfc ---&gt; &lt;cfset this.mappings['/components'] = "D:\Inetpub\wwwroot\myApp\components"&gt; </code></pre> <p>Somewhere in a normal cfm File I instatiate a cfc named test via:</p> <pre><code>&lt;cfset t = createObject("component", "components.test")&gt; </code></pre> <p>I want to set the mappings only once at <strong>onApplicationsStart</strong></p> <pre><code>&lt;cffunction name="OnApplicationStart" access="public" returntype="boolean" output="false" hint="Fires when the application is first created."&gt; &lt;!---create structure to hold configuration settings---&gt; &lt;cfset ini = structNew()&gt; &lt;cfset ini.iniFile = expandPath("./ApplicationProperties.ini")&gt; &lt;cfset application.ini = ini&gt; &lt;!--- read ini file ---&gt; &lt;cfset sections = getProfileSections(application.ini.iniFile)&gt; &lt;cfloop index="key" list="#sections.mappings#"&gt; &lt;cfset this.mappings[key] = getProfileString(application.ini.iniFile, "mappings", key)&gt; &lt;/cfloop&gt; </code></pre> <p>But this don't work because this.mappings is empty and next request. :(</p> <p>Putting this to OnRequestStart</p> <pre><code>&lt;!--- read ini file ---&gt; &lt;cfset sections = getProfileSections(application.ini.iniFile)&gt; &lt;cfloop index="key" list="#sections.mappings#"&gt; &lt;cfset this.mappings[key] = getProfileString(application.ini.iniFile, "mappings", key)&gt; &lt;/cfloop&gt; </code></pre> <p>I get an error that the component can't be found. This is strange. </p> <p>Putting the struct into Application scope </p> <pre><code> &lt;cfloop index="key" list="#sections.mappings#"&gt; &lt;cfset APPLICATION.mappings[key] = getProfileString(application.ini.iniFile, "mappings", key)&gt; &lt;/cfloop&gt; </code></pre> <p>How to call my Component?</p> <pre><code>&lt;cfset t = createObject("component", "application.components.test")&gt; </code></pre> <p>Doesn't work.</p> <p>So I have 3 targets.</p> <ol> <li>reading all pathes and mappings from ini file</li> <li>reading them once at ApplicationStart</li> <li>easy usage in sourcecode.</li> </ol>
