GRAVE: Allocate exception for servlet AdicionaContato java.lang.ClassNotFoundException: servlet

Pessoal, boa noite.

Como faço para que meu Servidor Tomcat reconheca meu driver JDBC? Devo colar o jar em alguma pasta do tomcat, criar alguma pasta (como LIB no meu projeto)?

Segue o código, lembrando que não terminei ainda!

Grato desde já pela ajuda!

O problema não é driver JDBC não. O problema é que o container não encontra a classe do seu Servlet. Confira os nomes das classes e dos pacotes e se a estrutura de diretórios está correta. Verifique se o aquivo se o arquivo AdicionaContatoServlet.class está na pasta WEB-INF/classes/Servlet.
