I'm preparing to make the switch from Struts 1.x to Struts 2 for new
development and had a few questions related to how objects used to render data
in a JSP page should be stored/retrieved for a desired http namespace. One of
the design tenants I try to employ in my current S1 webapp is minimizing
HttpSession bloat by storing objects needed to render jsp pages as request
attributes instead of session attributes. I understand S2 has tried to insulate
the actions from the http communication details by introducing the ValueStack.
I generally like the idea, but I'm having a difficult time understanding
how/when different items are pushed/popped. For example in my S1 action if I
knew the target jsp result page needed a list of objects as well as the current
user to display info I'd bind the objects to the view like so:
//List only need to render immediate next page
request.setAttribute("myListOfObjects", objectList);
//User needed to render immediate next page and other page
session.setAttribute("currentUser", currentUser);
How would I bind the objects in S2 such that the objectList is not present in
the ValueStack after the request? How do I ensure the currentUser is present in
the ValueStack for multiple requests?
Thanks in advance,
Jon
p.s. I've read through both the "Comparing Struts 1 and 2" and "Struts 1
Solutions" guides and didn't find the answer to my question.
