Olá,
no seu web.xml esta errado o servlet-class, este é para vc informar o pacote junto com a sua classe
entao ficaria assim…

<servlet> <servlet-name>primeiraServlet</servlet-name> <servlet-class>seu.pacote.OiMundo</servlet-class> <!--troque isso pelo seu pacote--> </servlet> <servlet-mapping> <servlet-name>primeiraServlet</servlet-name> <url-pattern>/oi</url-pattern> </servlet-mapping>

mas se esse meu pacote for o default ?

Cria um pacote chamado com e coloca sua classe lá.

Altera seu web.xml. [=

blz vou testar
vlw.
