Currently I am having a page with a small content need to be refreshed frequently.
For example: The jsp content is
Chapter 1 :
section abc:
section def:
section ghi:
Assuming I have a class Chapter and its sections are parameters in it
class Chapter{
Section abc;
Section def;
Section ghi;
}
I am using spring mvc, I am adding the following models
model.addAttribute("chapter", chapter);
model.addAttribute("abc", chapter.getAbc());
model.addAttribute("def", chapter.getDef());
model.addAttribute("ghi", chapter.getGhi());
While calling the main page initially I can load the individual sections by using the jsp:includes , while updating them independently I shall add that particular model to that particular jsp page and update it using ajax. This works fine.
But
The question is, How can I change the design so that can I manage the whole with just
model.addAttribute("chapter", chapter);
so that I can use the chapter object to get the abc,def,ghi values instead of explicitly passing them .
The problem is I am not able to pass the individual objects to the included jsps from the chapter object like ..
<jsp:include page="abc.jsp" >
<jsp:param name="abc" value="${ chapter.abc}"/>
</jsp:include>
this is not possible. as I can pass only strings
small problem , long description .. hope I made my point.
You can only pass Strings as request parameters, but you can set any kind of object as request attributes . Request scope (not page scope) beans should also work.
