application.cfc error with datasource

[Irish-Phoenix]

I am getting an error with my application.cfc file for my database. I am using coldfusion 10 on a windows machine. This application file works on cf 9 and 8 and I do not know what the problem is now. I get the error:

"

Error Occurred While Processing Request

Element DATASOURCE is undefined in APPLICATION."

This is my code and I have tried too make it work 2 ways:

<cfcomponent>

<cfset This.name = "My App">

<cfset This.datasource ="1093644">

<cfset This.clientmanagement="True">

<cfset This.loginstorage="Session">

<cfset This.sessionmanagement="True">

<cfset This.sessiontimeout="#createtimespan(0,0,10,0)#">

<cfset This.applicationtimeout="#createtimespan(5,0,0,0)#">

<cfset THIS.setClientCookies = "1">

<cfset THIS.setDomainCookies = "1">

<cfset THIS.scriptProtect = "All">

<cfsetting showdebugoutput="yes" />

<cffunction name="onApplicationStart" output="false" access="public">

<cfset APPLICATION.EncryptionKey = "S3xy8run3tt3s" />

<cfscript>

  APPLICATION = structNew();

  //site-wide datasource(s)

  APPLICATION.datasource = "1093644";

  strArgs = structNew(); // flush strArgs

  strArgs.datasource = APPLICATION.datasource;

    return true;

  </cfscript>

</cffunction>

I am trying to call it up with my queries like this:

<cfquery name="myQuery" datasource="#APPLICATION.datasource#" dbtype="ODBC">

This is a stupid error and I can't figure it out. I also tried doing this to put the db into the component:

<cfscript>

THIS.name = "myApp";

THIS.datasource = "1093644";

THIS.sessionManagement=true;

THIS.clientManagement=true;

THIS.applicationTimeout = createTimeSpan(0,0,20,0);

THIS.loginStorage = "session";

THIS.sessionTimeout = createTimeSpan(0,0,20,0);

if( isdefined('session') AND structkeyexists(session, 'times_logged_on')

AND session.times_logged_on gte 3 ) THIS.sessiontimeout =

createtimespan(0,0,10,0);

THIS.setClientCookies = 1;

THIS.setDomainCookies = 1;

THIS.scriptProtect = "All";

THIS.secureJSON = false;

THIS.secureJSONPrefix = "";

THIS.mappings = createMappings(pathPrefix="/");

</cfscript>

This app is on a mysql db. If I just use a query with the db name in it, it works. It's not liking my application.cfc code.

Can anyone help me figure out what the issue is? This is also on a shared hosting server.
Thank you.

APPLICATION = structNew();

That line is incorrect, so delete it. APPLICATION is already defined, as it is an in-built structure in ColdFusion.
