Vikramjit, The reason that Vector is Synchronized is the main reason why I would use it in a web application...
I dont want adhoc volatile values to be present.. 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.

You could use other Collection classes or check the List interface. My 2 cents: For inserting the values use LinkedList (since LinkedList is faster for insert operations). LinkedList provides sequential access, additions and deletions, at a cost of slower random access. For retrieving or reading the values use ArrayList (ArrayList is faster for read operations). For instance, if your program is to frequently provide random access to the data of the list, (for example, "show me item three, twelve, two, and twenty-five") the ArrayList class offers quick access to individual elements of the list. When working with ArrayList and LinkedList, there are two ways of creating the objects: List cityList = new ArrayList(); LinkedList peopleList = new LinkedList(); The above creation ensures that, line 1 that we are creating an ArrayList but we are gonna use it as a List. While line 2 that, we are gonna use a linked list as a LinkedList :). > Thanks for help, > > Snehal Vikram. > > ============================================================== > ============= > To unsubscribe: mailto [EMAIL PROTECTED] with body: > "signoff JSP-INTEREST". > For digest: mailto [EMAIL PROTECTED] with body: "set > JSP-INTEREST DIGEST". > Some relevant FAQs on JSP/Servlets can be found at: > > http://archives.java.sun.com/jsp-interest.html > http://java.sun.com/products/jsp/faq.html > http://www.esperanto.org.nz/jsp/jspfaq.jsp > http://www.jguru.com/faq/index.jsp > http://www.jspinsider.com > Disclaimer: This e-mail message along with any attachments is intended only for the addressee and may contain confidential and privileged information of GTL Limited.
