Não sei o que fiz de errado. Estava conseguindo subir o tomcat normalmente, e em determinado momento não consegui mais.

GRAVE: A child container failed during start
java.util.concurrent.ExecutionException: org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/vtpoo]]
GRAVE: A child container failed during start
java.util.concurrent.ExecutionException: org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost]]
GRAVE: The required Server component failed to start so Tomcat is unable to start.
org.apache.catalina.LifecycleException: Failed to start component [StandardServer[8005]]

Esses são alguns erros apresentados.

Como posso resolver isso?

Boa noite, meu xará! Como vai?

De acordo com essa linha do log de erro

Caused by: java.lang.IllegalArgumentException: Invalid <url-pattern> cadastroleitor in servlet mapping

Aparentemente deve ter um problema no arquivo web.xml!

Vc poderia colar o código aqui para eu dar uma olhada?

Meu web.xml contém apenas isso: 

<!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>
    <display-name>Vt Programação Orientada a Objeto 2</display-name>
    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>
</web-app>

Pra confirmar, esse é o meu projeto no github: https://github.com/GHardoim/VtPOO/blob/poo2/src/main/webapp/WEB-INF/web.xml

solução!

Opa, Gabriel! Me parece que o problema é na anotação @WebServlet na classe LeitorServlet! Veja se com o código abaixo o seu problema é resolvido!

@WebServlet(urlPatterns="/cadastroleitor")
public class LeitorServlet extends HttpServlet {

    // Restante do código omitido.
}

Qualquer coisa é só falar, meu aluno!

Muito obrigado!
