Element is Undefined Java Error on Adobe ColdFusion

An error that I’ve run into a few times when implementing new components in a ColdFusion website is “Element [COMPONENT NAME] is undefined in a Java object of type class…”

This error, when found in a development environment, is likely due to a typo in declaring locations for components in the Application.cfc file. (Or perhaps you just forgot to do it!) But what happens when your development environment works fine, but the error arises after migrating code to production?

In all likelihood, the application needs to be restarted (or you may restart the ColdFusion service, restarting all applications). This has fixed the issue for me every time.
