CKEditor is a javascript-based HTML "rich text" editor that works in common browsers. This component provides a wrapper around it for use in a Vaadin-based application. Vaadin 6: Developed using Vaadin 6.8.10 and CKEditor 4.1.1 in an Eclipse environment. This is no longer supported here. Vaadin 7: Developed using Vaadin 7.7.16 and CKEditor 4.11.3 in an Eclipse environment. This is currently being support. Vaadin 8: Currently no plans are in the works. Note there is another project that claims to have done so: https://vaadin.com/directory#!addon/ckeditor Vaadin 10: Unsure about this as it's unclear when we'll rework our huge Vaadin 7 app that makes use of the editor. You simply can drop the JAR file into your Vaadin WEB-INF/lib and begin using it, but as for all new add-ons, do a Vaadin widgetset compile. Note this was compiled with JDK 1.6.
