Because Google has lamely removed Downloads from Google Code in 2014, please visit the Vaadin Directory to download the JAR as of version 7.8.9.
We use two SVN branches as of May 2013 to handle the port to Vaadin 7. We now have branches named VAADIN6 and VAADIN7 that each contain the VaadinCKEditor Eclipse project code. We are not currently working on the 'trunk' at all.
The VAADIN6 branch version is developed using Vaadin 6.8.10 and CKEditor 4.1.1 in an Eclipse environment. You simply can drop the JAR file into your Vaadin WEB-INF/lib, compile widgetsets and then you can begin using it.
The VAADIN7 branch version is developed using Vaadin 7.2.6 and CKEditor 4.4.4 in an Eclipse environment. You simply can drop the JAR file into your Vaadin WEB-INF/lib, compile widgetsets and then you can begin using it.
A Vaadin 7-specific version is being developed in the ckeditor-for-vaadin7 project.
NOTE: This widget is compiled using JDK 1.6 / Java 6. We have been using 1.6 for years now (it was released December 2006) and see no reason to use such an outdated and no longer supported JDK 1.5 per Vaadin's widget specs.
It was built for use in the Open eSignForms open source electronic contracting and electronic signature web-based application (SaaS) where forms can be developed for electronic signatures, routing, etc.
NOTE: All code contributed to this project will be bundled under the single copyright owner, Yozons Inc., but of course it's released under Apache 2.0 so you are free to do with the code as you please.
