Nâo deu erro 404, mas sim erro 500. E a mensagem foi: “The ResourceConfig instance does not contain any root resource…”.

Como você configurou o jersey? Como está o web.xml?

Meu web.xml:

<display-name>RESTful CRUD Example</display-name>
<servlet>
   <servlet-name>jerseyServlet</servlet-name>
   <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
   <init-param>
       <param-name>com.sun.jersey.config.property.packages</param-name>
       <param-value>org.o7planning.restfulcrud</param-value>
   </init-param>
   <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>jerseyServlet</servlet-name>
    <url-pattern>/rest/*</url-pattern>
</servlet-mapping>

Será que ta errado?
