Olá a todos, estou adorando estudar Java pra Web e também estou gostando do Conteúdo que está na apostila, mais estou com um problema, tenho uma pagina index que chama um método no Controller que é o “novaTarefa”, mais sequer executa esse método, já aparecendo na tela o seguinte erro

HTTP Status 500 - Servlet.init() for servlet springmvc threw exception

type Exception report

Creio que faltou o jar do SL4J no seu classpath.
O Hibernate validator depende dele.
