In order to be build properly, the examples must have following folder structure:

example - java                  must contain all sources of the example. Can have packages (subfolders).
                                MUST contain .properties if needed.
        - WEB-INF		must contain web.xml (in lowercase characters!).
        - mimes                 Possible folder for all mimes used in the project.
        - jsp                   Possible folder for JSP.


Additional folders are possible.
