ApplicationScopeTracker Class not Found & Class path definition

Chris_Young · February 10, 2017, 10:35am

Hi There,

I currently trying to move a CF application over to Lucee, however I am
getting the following error:

cannot load class through its string name, because no definition for the
class with the specified name [coldfusion.runtime.ApplicationScopeTracker]
could be found caused by
(java.lang.ClassNotFoundException:coldfusion.runtime.ApplicationScopeTracker;java.lang.ClassNotFoundException:coldfusion.runtime.ApplicationScopeTracker
not found by lucee.core [64]

I’m trying to find the Lucee alternative but it is proving tricky - would
anyone be able to shed some kind of light on this?

Also - on our CF application we define a ColdFusion Class Path Class
Path directory, I also can’t seem to find this setting in Lucee - would
anyone be able to shed some light on this too?

Many thanks in advance.

I think you’ll need to provide some more details.

ApplicationScopeTracker is an internal ACF class. (undocumented,
unsupported access) To provide alternatives we’d need to know what you’re
trying to do, and why. Access variables from other application scopes? (in
which case, you’re breaking encapsulation. But I’ve done it) List all
applications on the server? (again, why?)

Similarly, Coldfusion Class Path would add java libraries to the mix…
what libraries? For what purpose?

Application.cfc provides ways to add java libraries, as does Javaloader, as
does adding the libraries to the WEB-INF/lib folder, or the more
complicated solution of making OSGi bundles. It all depends on what you
need the library for, where you’re accessing it, etc.

Also note I tested this against Lucee 5. (You didn’t specify a Lucee
version)

This is more legacy code - and IMO a bad approach - but there isn’t scope
to change it if needed. We are using the ApplicationScopeTracker (and the
session tracker) to grab the application variables and session collections
from an admin app that runs with our website. Essentially they need to run
alongside each other.

For the class paths - our CMS comes with a number of different classes so
these need to be included.

The application scope tracker is not available (AFAIK) but I can see there is a SessionTracker:
Lucee/core/src/main/java/coldfusion/runtime at master · lucee/Lucee · GitHub https://github.com/lucee/Lucee/tree/master/core/src/main/java/coldfusion/runtime

What do you need to get from the ApplicationScopeTracker?

Easiest thing for libs is to just use an Application.cfc setting, i.e. see
Luis’s excellent polyglot.

github.com

lmajano/messaging-polyglot/blob/master/consumer/cfml/Application.cfc

component{

	this.name 					 = "RabbitMQ Producer";
	this.mappings[ "/rabbitmq" ] = getDirectoryFromPath( getCurrentTemplatePath() );
	this.javaSettings 			 = { loadPaths = [ "/lib/amqp-client-5.1.2" ] };

	function onApplicationStart(){

		// create connection factory
		application.factory = createObject( "java", "com.rabbitmq.client.ConnectionFactory" ).init();
		application.factory.setUsername( "rabbitmq" );
		application.factory.setPassword( "rabbitmq" );
		// Create a shared connection for this application
		application.connection = application.factory.newConnection();

		return true;
	}

	function onAplicationStop(){
		// close connection
