Where can source code be found in CRX DE?

The source code in CRX DE (Content Repository Extreme Developer Edition) is primarily located in the apps folder. This folder is specifically designed to hold applications and custom code developed on the AEM platform. It includes the Java Servlet files, JSP files, and other necessary components that make up the functionality of the AEM applications.

The apps folder serves as the primary repository for code written to extend or modify AEM capabilities. When building custom applications, developers will typically create and maintain their code within this directory to ensure it is adequately organized and accessible within the AEM environment.

In contrast, the config folder is primarily used for configurations and settings, the content folder is focused on the content structure and assets managed by AEM (like pages, images, and documents), and the resources folder often contains shared resources such as client libraries or front-end assets rather than the source code itself. Thus, the apps folder is the correct location for finding source code in CRX DE within AEM.
