Galera, estou com um probleminha báaasico no tomCat.

Eu instalei o bichano e criei uma jsp simples. Funciounoou!

Despois eu criei uma classe Pessoa bem simples, só para testar…

Aí eu usei um scriptlet para chamar a bem dita:

<%Pessoa p=new Pessoa();%>

Agora esta dando erro!!!
Já revirei o web.xml e nada…
ja coloquei o arquivo .class em todas as pastas e nada…
Alguém poderia me ajudar?

Vejam o trace:

Você não deu import na classe Pessoa.

Aganiuipuque 1 de jan. de 2005

Já fiz o import e nada…

tentei assim:

<%@ page language=“java” import=“laboratorio.jsp.*”%>

depois assim:

<%impor laboratorio.jsp.*;%>

E ainda nao consegui…

Veja a estrutura de pastas:

Na pasta .jsp estão todas a paginas jsp (é obvio)
Na pasta classes está a classe Pessoa compilada

Aqui está o web.xml que se encontra na pasta WEB-INF:

<?xml version="1.0" encoding="ISO-8859-1"?>

<!DOCTYPE web-app
PUBLIC “-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN”
“http://java.sun.com/dtd/web-app_2_3.dtd”>

<web-app>

<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>

</web-app>

E este é o arquivo server.xml que está na pasta conf do TomCat:

<?xml version='1.0' encoding='utf-8'?>

Algúem poderia dar uma ajuda?

Olá,

a classe Pessoa está dentro do package laboratorio.jsp ???
se tiver tem algo errado com sua estrutura de diretorios

Deveria ter um diretorio laboratorio/jsp dentro do diretorio classes, que seria o lugar correto de sua classe Pessoa.
Mas se não tiver um package crie um…comigo já aconteceu o mesmo erro uma vez, e minha classe não tinha package, depois que eu cruei funcionou…

Qualquer duvida só postar!
Feliz 2005!!

CAra…
eu criei um package dentro da pasta web-inf/classes chamado LAB
e dentro de LAB eu adicionei o arquivos .jsp e o arquivo .class…

nao rolou…

Nao tem que fazer nada no web.xml ou server.xml ?

rodrigo_gomes 2 de jan. de 2005

dentro de WEB-INF/classes/LAB deve ter somente os seus .class, e nessas classes tem que ser especificado o package LAB, aí então no jsp você o importa...
[code]<%@ page language="java" import="LAB.Pessoa"%>

Cara…
Firmeza, deu certo!

Eu não estava “dizendo” na classe Pessoa que a package era “lab”.

Então acrescentei esta linha:

package lab;

Agora está funcionando!!!

Valeu mesmo irmãozinho!!
