TinyMCE is a powerful and flexible rich text editor that can be embedded in the user’s web application.

TinyMCE is a WYSIWYG editor (or called rich text editor) similar in concept to FCKEditor and htmlArea, for those who want the richness of the editor and don't mind losing the simplicity and control that standard Wiki markup allows.

JSPWiki comes already shipped with a simple WYSIWYG editor. With TinyMCE you can add a more feature-rich editor.
