I like CKFinder, but it is a commercial product. I also like KCFinder, but it works on PHP only, I need it to run on Java/JSP.
Know any open source Java/JSP web file manager?
Edit:
The next best thing I found is this, http://www.vonloesch.de/filebrowser.html but it is quite old and basic.
I found a workaround..
First install the old FCKEditor Java, -> http://sourceforge.net/projects/fckeditor/files/
Then use the following instruction to integrate it with CKEditor. http://docs.gpeasy.org/index.php/Main/CKEditor_Integration
