exception

javax.servlet.ServletException: Wrapper cannot find servlet class br.com.junior.servlet.Candidato or a class it depends on
org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102)

Web.xml

[code]<?xml version="1.0" encoding="ISO-8859-1"?>

Aplicacao web simples

<servlet>
	<servlet-name>servletDeTeste</servlet-name>
	<servlet-class>br.com.junior.servlet.Candidato</servlet-class>
</servlet>
<servlet-mapping>
	<servlet-name>servletDeTeste</servlet-name>
	<url-pattern>/oi</url-pattern>
</servlet-mapping>

[/code]

[code]@Override
protected void service(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {

	PrintWriter write = response.getWriter();
	
	write.println("<html>");
	int idade = Integer.parseInt(request.getParameter("idade"));
	write.println( idade);
	write.println("</html>");
}[/code]

Seu servlet não foi encontrado, veja direitinho o caminho do web.xml e da classe, e aquele código dentro do método service eu acho que é dentro doGet ou doPost

Cara dei uma olhada e o caminho está ok, entao peguei um exemplo da fj21 da caelum e também está dando o mesmo erro, você tem mais alguma sugestão??

web.xml

&lt;?xml version=&quot;1.0&quot; encoding=&quot;ISO-8859-1&quot;?&gt; &lt;web-app xmlns="http://java.sun.com/xml/ns/j2ee" version="2.4"&gt; &lt;display-name&gt;Aplicacao web simples&lt;/display-name&gt; &lt;servlet&gt; &lt;servlet-name&gt;Teste&lt;/servlet-name&gt; &lt;servlet-class&gt;br.com.caelum.servlet.OiMundo&lt;/servlet-class&gt; &lt;/servlet&gt; &lt;servlet-mapping&gt; &lt;servlet-name&gt;Teste&lt;/servlet-name&gt; &lt;url-pattern&gt;/oi&lt;/url-pattern&gt; &lt;/servlet-mapping&gt; &lt;/web-app&gt;

[code]package br.com.caelum.servlet;

import java.io.IOException;
import java.io.PrintWriter;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class OiMundo extends HttpServlet{

@Override
protected void service(HttpServletRequest req, HttpServletResponse resp)
		throws ServletException, IOException {
	PrintWriter out = resp.getWriter();
	out.println("&lt;html&gt;");
	out.println("teste");
	out.println("&lt;/html&gt;");
}

}[/code]
