Erro em página JSP/Servlet
Pessoal, é o seguinte... tou com um erro que todo mundo já teve alguma vez na vida e cada um deu jeito de uma forma diferente. Tentei todas as alternativas que encontrei pela net e nada resolveu meu problema.
O erro é o:
"HTTP Status 404 - /Indicadores/relatorios/ServletPrincipal
type Status report
message /Indicadores/relatorios/Se /Indicadores/relatorios/ServletPrincipal
orios/ServletPrincipal
description The requested resource (/Indicadores/relatorios/ServletPrincipal) is not available.
Apache Tomcat/5.5.17"
Na realidade meu servlet não está na pasta relatorios e sim na Indicadores/src/java/Controle, sei que o erro é algum mapeamento, mas não consigo resolver.
Estou usando:
Netbeans 5.5.1
JDK 6
Windows XP
Mantive a estrutura de diretórios que o próprio netbeans utiliza.
