Arquivo Discussoes de Programacao e Tecnologia 
Estou com um problema para efetuar a atualização de valores em uma div, la eu tenho alguns beans que imprimem o valor de uma classe porem toda alteração atualizo toda a pagina so para mostrar o novo valor, estou usando ajax para enviar os dados via post, uso servlet e jsp sem framework.
Desde ja obrigado
Poste o código para ficar mais fácil.

meu ajax com Jquery, no firefox ta lindo de ver mais no IE ele nao atualiza certo, atualiza 'quando quer', vi uns problemas de cache porem ja tentei de tudo para desabilitar e nada
