Yes, 0.5 replaced @UriTemplate with @Path

It's a NumberFormatException there, and it's caused by the fact there's no
expected QueryParam in a request.
You need to use @UriParam instead (please note in 0.6 it will be replaced with
@PathParam), see below...

Yes, starrting from 0.5 one can use @HttpMethod to create designators, sucg as
@GET/@[EMAIL PROTECTED]/@DELETE,
so you may for example create @GetRequest if you think it's better than @GET or
create designators for other http methods
Here's the class :
@Path("/emitterResource")
public class EmitterResource {
@GET
@Path("/getEmitters")
public Collection<Emitter> getEmitters() {
return emitterDAO.getAllEmitters();
}
@GET
@Path("/emitters/{emitterId}")
public Emitter getEmitter(@UriParam("emitterId") int id) {
LOG.debug("looking for emitter id " + id);
return emitterDAO.get(id);
}
}
You might want to chnage it like this to minimize a bit the numbner of
annotations :
@Path("/emitters")
public class EmitterResource {
@GET
public Collection<Emitter> getEmitters() {
return emitterDAO.getAllEmitters();
}
@GET
@Path("{emitterId}")
public Emitter getEmitter(@UriParam("emitterId") int id) {
LOG.debug("looking for emitter id " + id);
return emitterDAO.get(id);
}
}
Hope it helps
Cheers, Sergey
