Maya, Vectors are synchronized. Any method that touches the Vector's contents
is thread safe. ArrayList, on the other hand, is unsynchronized, making them,
therefore, not thread safe. With that difference in mind, using synchronization
will incur a performance hit. So if you don't need a thread-safe collection,
use the ArrayList. Why pay the price of synchronization unnecessarily?
Also can you tell me what exactly are you storing in vector?
I need this to tell you the best possible answer as when navigating through the
pages (through actions) if the information is small you can use hidden values
to pass the values around which you want to manage
Cheers

Manoj,
Yes, I am storing a vector in request attribute. Using session attribute, I
am not feeling comfortable. Because the application can be accessed
simultaneously by lots.
So, In EditAction, is there a way to get the attribute from request ?

Maya,
It seems you storing a list of records in request
Set the attribute in session scope, and when you delete the record update the
attribute in session when you are in editAction
Or
In Edit action again set the update attribute in request scope
Cheers

Hi all,
1. I have an action class, DisplayAction which displays the records from
database. Here I am setting a vector into the request scope and on success
forwarding it to displayresults.jsp.
2. Display results.jsp displays all records with an option of delete to the
users.
3. Now, once user deletes the records, by going to editaction, on success it
should again display the displayresults.jsp. How will I get the attribute I set
in step one here again.
what path should I follow ?
DisplayAction -> displayResults -> EditAction
EditAction should again display displayResults and get the attribute set in
DisplayAction.
Please help
