CKEditor.Java provides an object with a simple interface for creating and configuring an editor instance. This makes the deployment of the CKEditor a piece of cake. It is intended to be used in servlet-based systems like JSP as well as template engines like Velocity or FreeMarker. There are some notable differences between this library and the official CKEditor for Java library. CKEditor.Java isn't focused on JSP and can be used in all servlet-based systems. A tag library isn't provided yet! It also has advanced handling of properties. It's possible to set all CKEditor configuration for the entire Web application in one properties file. This keeps the front-end code clean. The state-of-the-art logging facade slf4j is used.
C5Connector.Java is a backend for the Core Five file manager. It provides a bridge between the file manager and a storage backend and works like a transparent virtual file system or a proxy. It includes a default implementation for accessing the local filesystem (on the server side). The API encapsulates the building of JSON and is intended to be used within JSPs as well as with a template engine like Velocity or FreeMarker.
