Hi Roan,
From the console Jersey is not finding any root resource classes in
the package "com.citespace".
Is the class UsuarioResource annotated with a @Path?
If not, then it needs to be so.
If yes, then i am guessing the Jersey's package scanning algorithm is
not working correctly when using Jetty on Eclipse, but as Jakub shows
is works OK when using "mvn jetty:war-run".
As a work around you could try using:
<init-param>
<param-
name>com.sun.jersey.config.property.resourceConfigClass</param-name>
<param-
value>com.sun.jersey.api.core.ClassNamesResourceConfig</param-value>
</init-param>
<init-param>
<param-name>com.sun.jersey.config.property.classnames</
param-name>
<param-value>com.citespace.UsuarioResource</param-value>
</init-param>
Paul.
