Title: RE: [enterprise-list] Classe objeto = null (erro em JavaBean com JSP)
Valeu, Vieira. Funcionou.
 
Outra coisa: li em algum lugar algo sobre proteger os arquivos colocando-os no diret�rio WEB-INF. Fiz isso com o meu arquivo jsp, que passou a n�o ser acessado. Se esta id�ia � correta, como (e onde) configurar o servidor para encontrar os arquivos?
 
Obrigado novamente.

Adicione seu bean a um package.

Olhe em http://java.oreilly.com/news/jsptips_1100.html na sessao 6.

    Por favor, algu�m pode me ajudar com o problema abaixo? O exemplo � do livro
    Core Servlets and Java Server Pages, mas o erro aparece em qualquer
    tentativa de rodar um jsp com javabean.
    Os exemplos do Tomcat 4.1.18 funcionam normalmente, o que mostra uma
    instala��o saud�vel.


    No arquivo jsp:

    <jsp:useBean id="stringBean" scope="session" class="StringBean" />


    A classe StringBean:

    public class StringBean  {
        private String message = "Nenhuma mensagem especificada";

        public String getMessage() {
            return (message);
        }

        public void setMessage(String message) {
            this.message = message;
        }

    }


    Os erros na execu��o:

    StringBean$jsp.java [64:1] cannot resolve symbol
    symbol  : class StringBean
    location: class org.apache.jsp.StringBean$jsp
                    StringBean stringBean = null;
                    ^

    ("stringBean")).getMessage())));
                                                            ^
    4 errors
    Errors compiling StringBean.
