Pessoal…to começando a aprender JSP e servlets.
Estou seguindo os exemplos do livro de deitel, e como estou começando, estou fazendo tudo na mão, inclusive o arquivo web.xml.
Bem, existem 4 definições de servlets no arquivo abaixo. Antes de adicionar a quarta, tudo funcionava muito bem…depois que adicionei a quarta definição de servlet ao arquivo, o tomcat está dando erro 404 (resource not available). Se apagar o quarto servlet tudo funciona normalmente…
Alguém me dá uma luz?
