Hi,
I'm planning my approach to a data driven app that I have to write in the near
future. I've used struts before in more of a demo-type, proof of concept
scenarios, and am no where near and expert, but now need to build a production
level system.
For a web app that needed to display a username on every screen I was
previously doing it like this:
HttpSession zCurrentSession = request.getSession(false);
if (zCurrentSession == null){
zCurrentSession = request.getSession(true);
}
try {
zUserInfoBn = zUserData.getUserInfo(sEmailAddress);
zUserInfoBn.setIsLoggedIn(true);
}catch (ApplicationException zAppEx){
throw zAppEx; //stubbed out not complete
}
zCurrentSession.setAttribute(sUSERINFO_BN, zUserInfoBn);
So I'm hoping I can get some opinions on how to display things like user
information on the screens in an intelligent way. I'm not sure where the trade
offs are between hitting the DB every time and storing at the request level,
using cookies, or storing it some other way.
Any ideas would be helpful. I'm in the rare position of being able to take my
time and think out the approach and would love input from people who've got
more experience than me.
My env is linux, tomcat 5.0.28, latest jdk, struts, separate box running db
(sql server 2000 w/ stored procs) on a 2.8ghz xeon box with 1 gig mem. To
start the app shouldnt get more than 50,000 page views a month.
Thanks
