DoxMentor4J

DoxMentor4J is a standalone, cross-platform, Web/AJAX based documentation library that is fully searchable and may be hosted in the file system, in an archive, or embedded in the Java classpath. Users can copy online books or manuals into directories in the library directory structure. DoxMentor4J then provides a dedicated Web server which presents the library as a tree structure on a Web page. Users can navigate through the tree to locate online books.
