I dont think in web application you need to care about threads, since the container handles all the threading issues for you. Vectors were basically used for legacy systems (you can read more in Thinking in JAVA-Bruce Eckel) As far is volatile values, they arise in stand alone applications and not web driven. > > Snehal, > > Could u explain what do u mean by Master Value... do u mean > for ex.. of > populating drop down lists, a list that is common across > users and sessions. > like an Application level data... > > if so then yes i would use a Synchronized Collection object, > Vector works > inplictly as a Synchronized Object, but if u want to use > another class then > I would recomend using the Synchroinzation technique in the > Collections > class so as to maintain data itegrity. > > Amit.
