Hi ,

I have a two listboxes on a JSP Page.I move some of the elements from first Listbox(which contains Available Data) to the other(which is blank when the page loads for the first time).When I click next button , I should check if my Second Listbox contains some data.If not, I should show user an error message.How do I do this ?

Thanks in Advance,
