Boa tarde!!
Estou precisando de ajuda com o seguinte tutorial disponibilizado na doc do netbeans 6.1, que foi arquivada…
Minha dúvida é a seguinte, no método do botão “send” (action_send), há uma invocação do getComment(), mas a implementação do mesmo não está presente no tutorial, como faço para obter o valor do textfield que está em tag JSP?? O tutorial está anexado no post.
Muito obrigado.
Alguém??

Nesse exemplo, o getComment nao foi implementado. Preciso de ajuda em como captar esse valor, caso precise, no tutorial tem todo o código, anexado no primeiro post. Espero que alguém possa me ajudar, acredito que seja simples…
Alguma sugestão???
