FCKEditor 2.5 image uploads (integration)

Hi,
I was wondering if there are instructions available to integrate the image insert/upload operations for application running on tomcat. My application is developed using spring mvc and I use the javascript method to integrate fckeditor. I read the documentation and could not find anything that would allow to use connectors for my setup.
Is there a separate integration package for image inserts and uploads or am I missing anything?

Thanks
