Do you mean taglib or Java objects ?
If you mean java objects, you only get in your JSP what the associated controller has register in the request parameter.
To get a good overview of the involving process check the following files :
- LS_ROOT/Src/LS-Client/Default-WebApp/WEB-INF/libresource-web.xml => This give the binding between an action and the controller to use
- LS_ROOT/Src/LS-Client/Default-WebApp/WEB-INF/src/java/org/libresource/web/controllers/wiki/PageController.java => One of the previous controller
- LS_ROOT/Src/LS-Client/Default-WebApp/pages/modules/wiki/viewPage.jsp => One of the jsp associated to the previous controller
Hope this could help…
