*/
package beans;
import clients.NewJerseyClient;
import entities.ReservationItem;
import java.io.Serializable;
import java.util.ArrayList;
import java.util.Date;
import java.util.List;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
import javax.ws.rs.core.GenericType;
import parameters.ReservationParam;
import org.glassfish.jersey.client.ClientResponse;
/**

* #author subhi2
*/
#ManagedBean
#SessionScoped
public class PageController implements Serializable {
public String moveToPage2() {
NewJerseyClient client = new NewJerseyClient();
ClientResponse response = client.findInsertedReservationItem(ClientResponse.class, "22", "2010-07-26T11:15:51", "2014-07-26T11:15:51");
GenericType<List<ReservationItem>> genericType = new GenericType<List<ReservationItem>>() {
};
// Returns an ArrayList of Players from the web service
List<ReservationItem> data = new ArrayList<ReservationItem>();
data = (response.getEntity(genericType));
return data.toString();
}
}
the line
data = (response.getEntity(genericType));
cause the error
this code was working with old jersey but now what should I do to solve this error ?

Answer 1

You can change response.getEntity(genericType) by response.readEntity(genericType)

Answer 2

For what you are asking I've replaced this
response.getEntity(String.class);
by this
response.getEntityStream().toString();
But there could be another problems related with Jersey 2, I could get it working by replacing these imports
import jersey.spi.container.servlet.ServletContainer;
import com.sun.jersey.api.client.ClientResponse;
import com.sun.jersey.api.client.Client;
import com.sun.jersey.api.client.WebResource;
By these
import org.glassfish.jersey.servlet.ServletContainer;
import org.glassfish.jersey.client.ClientResponse;
import javax.ws.rs.client.Client;
import javax.ws.rs.client.ClientBuilder;
and in the code (as I was using Jetty) I had to replace this
servletHolder.setInitParameter("com.sun.jersey.config.property.packages",
"resources");
by this
servletHolder.setInitParameter("jersey.config.server.provider.packages",
"resources");
and this
WebResource webResource = client.resource("http://url_u_want_to_connect");
ClientResponse response = webResource.accept("application/json")
by this
WebTarget webTarget = client.target("http://url_u_want_to_connect");
ClientResponse response = webTarget.request("application/json")
Finally here is a link for "latest" docs (It's about Jersey 2.x, at 2013)
