 +====== JSP Pages ======
 +===== Login =====
 +
 +Add ''login.jsp'' to ''/WEB-INF/jsp'' \\ 
 +

 +<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"

 +
 +You are free to change the implementation of the loginpage, \\ 
 +you'll find it easier to rely on an old fashioned form submit to login a user, the system will then redirect to app.html (app.jsp)
 +===== App =====
 +
 +Add ''app.jsp'' to ''/WEB-INF/jsp'' \\ 
 +
 +this should be the index.html of your extjs application
 +====== Static resources (javascript, css, ...) ======
 +
 +Don'y use html pages, use jsp like above.
 +simply place the resource in ''/static/'' or any subfolder there
