[RESOLVIDO] Algum problema besta com Servlet

Front-end
#1

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:

<?xml version="1.0"?> 
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
 
          <display­-name>Login</display-­name>
          
          <servlet>
          <servlet-name>Login</servlet-name>
          <servlet-class>com.login.controller.ChecarLogin</servlet-class>
          </servlet>
          
          <servlet-mapping>
          <servlet-name>Login</servlet-name>
          <url-pattern>/checarLogin</url-pattern>
          </servlet-mapping>
</web-­app>

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

[code]HTTP Status 404 - /checarLogin

type Status report

message /checarLogin

description The requested resource (/checarLogin) is not available.
Apache Tomcat/6.0.16
[/code]

Pelo form action do index.jsp eu tenho:

<form action="checarLogin" method="POST">

A minha estrutura de diretórios:



		login	
*src
--com
  --login
    --controller
      --ChecarLogin.java
    --model

*web
index.jsp
web.xml
--images
--WEB-INF
  --classes
    --com
      --login
        --controller
          --ChecarLogin.class
  --lib
    --mysqlconnector.jar

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.

#3

Você poderia também mudar o

&lt;url-pattern&gt;/minha-app/checarLogin&lt;/url-pattern&gt;

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

#5

checou os logs?

#6

Boa idéia. não havia pensado nisso… rs.

Deixa eu dar um olhada aqui…

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…

#10

deleta essa aplicação então…

#11

como perguntar não ofende… :slight_smile:

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

[quote=raf4ever]como perguntar não ofende… :slight_smile:

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.

#13

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!

#15

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.

#16

Ok, ja vi que um dos problemas que estava dando era com a tag display-name e o local doa rquivo, que ja foi modificado para WEB-INF.

Mas continua dando 404… E agora hein? :cry:

#17

Fiz rodar, era só isso o problema besta. O caminho do web.xml e a localização do servlet. Nada mais.

Desculpem pelas 2 paginas de nada. =) rs.
