i m trying to run my ear project on server and when i test a request which must show the list of products it only shows one product. i have some friendsworking on the same project, they executed the same code and it worked on their machines.
how can i fix it?
the request: localhost:9050/WebServiceRest/produit/produits
the method :
@GET
@Path("/produits")
@Produces(MediaType.APPLICATION_JSON)
public List<Produit> listProduits(){
return metier.listeProduits();
}
