Hi
I want to display the data in a tree view.
To fetch the data from database, populating the data in Vector object
and forwarding the same to a jsp file thro' servlet coding.
In the jsp i am getting the vector objects from the request object and
displaying the data.
The code is perfectly working when the application starts.
When the browser is idle for some time and again i try to access the links, the vector objects are giving the last accessed values and not refreshing the data.
When i restarts the server everything is perfect. I am not using the session object.

Pl. can you point me where i have to make correction to solve this problem.
ThanX,
Senthil

hi,
When u r in the development stage set the reload interval to a minimum value,because u need to make changes often,but once everything is developed then set the reload interval to the default value.
At present reduce the reload interval.
ur problem will be solved.

Is it browser caching?

When you click refresh, or the 'link' a second time, is there something you can put in your servlet to confirm that it's refreshing the vector? ie: System.out.println("refreshing vector");
