In my project I am using stateful session bean, in which I have a method (which is used for comparing & displaying product specifications) in that method I am storing a vector(which contains the String objects) as an element of another vector(to serve the purpose as a two dimensional array).
My problem is that for the first page( there may be many pages to be displayed on the browser by using jsp) this vector works fine. But when i go to the next page the following error comes.I am using Inprise application server.I dont have any clue about the error. Any help will be appreciated.
thanx in advance.
