You are not wrong, florian, at the end of days what you should present to user are strings. The question is: how to retrieve those strings? One possible answer is by means of valueObjects. Let's think to the classic user's data (email, password, first name, last name, etc.) and to a normal Register/Login/Logout/Remove pattern. Well, presumibly, you'll need to pass back and forward user's data from/to the persistance layer (which possibly could be a database); then, valueObject is a unique course grained object containing all the user's information. You can then use parts of this valueObjects in your JSP to render information to the user or form a unique valueObject when user supplies information to you, to pass to the persistance layer. So, from within your JSP page, instead of everytime do something like:
<% getUserService.getEmail(); %> for each user's info, you can just get pieces of a valueObject created before the JSP presentation.
