[RESOLVIDO] Algum problema besta com Servlet

GUJ Master Membro desde: 30/03/2008 20:56:41 Mensagens: 1293 Offline

Olá galera,

Bem, estou com um problema que eu acho que é algum detalhe bem besta que estou esquecendo. Estou criando uma telinha de login que consulta num BD MySQL, até aí tudo certo, compila legal sem nenhum erro. (Nem quero mostrar o codigo pq fiz em 9 minutos exatos e tá uma coisa monstruosamente PORCA). Eu acho que é algum probleminha besta de configuração.

Alterei o server.xml do tomcat para rodar pela porta 80, ok. Entao eu digito http://localhost/login e voi là! A telinha JSP aparece.

Agora nos temos o seguinte arquivo web.xml:

Ok, entao quando eu digitasse http://localhost/login/checarLogin eu deveria ter o servlet. Mas ao invés disso tenho:

Pelo form action do index.jsp eu tenho:

A minha estrutura de diretórios:

Eu gostaria de saber porque diabos está dando a porcaria do 404.

PS: Setei a permissão do .class pra 777 e tudo mais.

Tente http://localhost/checarLogin, SEM o 'login' na URL.
O Servlet não respeita a estrutura de diretórios. Ele é acessado da raiz do contexto.

Mudei o web.xml, tentei acessar desse outro jeito e...
Nada, não deu em nada.. Continua 404 ;(

Mas então cara, essa aplicação CH1 não é a que estou agora, a que estou é a Login...

Essa é uma que eu tava testando ainda...

deleta essa aplicação então..

como perguntar não ofende...

tu estás usando doPost() ou service() no teu servlet?

Rsrs. Relaxa, eu sou bem iniciante ainda em WEB.

No servlet, sobrescrevi a ação do DoGet() e no corpo do metodo coloquei para DoPost().

Não sobrescrevi o método Service().

Mas cara, esse erro é 404, diz que nao localiza. Se fosse algum erro no bytecode ele acusaria depois que tentasse acessar, eu estaria feliz se ele estivesse acusando um erro no codigo, rsrsrs.

Oi,

Tá dando exception de encoding na aplicacao ch1, se voce nao conseguir remover ela pelo manager/html pode fazer o que sugeriram, pare o tomcat, dá um delete na pasta, limpa os logs, reinicia o tomcat.. deve funcionar..

Outra coisa, se você nao quiser se preocupar se a requisicao vem por GET, POST, etc, basta colocar o seu codigo direto no service que o container se vira..

Olá galera,

Bme, uma coisa. Eu estou rodando o Tomcat pelo plugin da Sysdeo instalado do Eclipse Ganymede.

Mas acontece que eu posso reestartar, etc, e os arquivos de log dentro de /home/darkstar/apache-tomcat/logs nao sao alterados, no caso, ele nao usa o diretório de log default do tomcat. Alguem sabe qual ele usa?

[]'s!

GUJ Master Membro desde: 30/03/2008 20:56:41 Mensagens: 1293 Offline

E outra coisa, quando eu coloco o arquivo web.xml dentro do diretorio web/ a index.jsp aparece. Mas se eu coloco o arquivo web.xml dentro do /web/WEB-INF ele não mostra o index.jsp nem o servlet.

grato.
