Criação de Servlets

Programação Java
#1

Olá pessoal!

Gostaria de saber como eu faço para criar um servlet utilizando o Eclipse? Até agora, fiz o seguinte:

  1. Criei um projeto (TomcatProject);
  2. Ele gerou 2 WEB-INF (WEB-INF/src e WEB-INF);
  3. Criei um servlet na pasta WEB-INF/src, e o web.xml na pasta WEB-INF;
  4. Iniciei o Tomcat e chamei a aplicação.

Só que dá erro 404! Vcs tem alguma idéia do que pode ser? Estou usando Eclipse 3.1 e Tomcat 6.0.

Desde já agradeço.

Como está a configuração do seu Servlet no web.xml?

Você compilou a classe e já verificou se a mesma se encontra no diretório WEB-INF/classes?

#3

Sim, o .class está dentro de WEB-INF. O meu web.xml está assim:

<?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>

&lt;servlet&gt; 
    &lt;servlet-name&gt;primServ&lt;/servlet-name&gt; 
    &lt;servlet-class&gt;primServ&lt;/servlet-class&gt; 
&lt;/servlet&gt;    
 
&lt;servlet-mapping&gt; 
    &lt;servlet-name&gt;primServ&lt;/servlet-name&gt; 
    &lt;url-pattern&gt;/primServ&lt;/url-pattern&gt; 
&lt;/servlet-mapping&gt; 

&lt;session-config&gt; 
    &lt;session-timeout&gt;30&lt;/session-timeout&gt; &lt;!-- 30 minutes --&gt; 
&lt;/session-config&gt;

</web-app>

#4

Sua classe está dentro do WEB-INF ou WEB-INF/classes?

#5

Está dentro do WEB-INF

#6

Tem que colocar as classes dentro de WEB-INF/classes.

#7

Já coloquei, mas continua com o mesmo erro… Acho que talvez seja algum problema de configuração do Tomcat, pois quando vou iniciá-lo, aparece as seguintes mensagens:

Isto é tudo o que aparece no meu console quando inicio o Tomcat! Eu consigo executar jsp’s, mas não servlets. Será que você sabe o que é?

Obrigada.
