	private int locationId;
	private String ort;
	private String PLZ;
	private String strasse;
	private String country;
//Setters und Getters
}

package inventory;
 
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
 
import beans.Location;
 
@Path("/location/plz")
public class LocationService {
 
	@GET
	@Path("/get")
	@Produces("text/html")
	public Location getLocationInHTML() {
 
		Location loc = new Location();
 
		loc.setCountry("Deutschland");
		loc.setLocationId(1);

import com.sun.jersey.api.client.ClientResponse;
import com.sun.jersey.api.client.WebResource;
 
public class LocationClientGet {
 
	// http://localhost:8080/StammDaten/eumonis/location/plz/get
 
	public static void main(String[] args) {
 
		try {
 
			Client client = Client.create();
 
			WebResource webResource = client.resource("http://localhost:8080/StammDaten/eumonis/location/plz/get");
 
			ClientResponse response = webResource.accept("text/html").get(ClientResponse.class);
 
			if (response.getStatus() != 200) {
			   throw new RuntimeException("Failed : HTTP error code : " + response.getStatus());
			}
 
			String output = response.getEntity(String.class);
 
			System.out.println("Output from Server .... \n");
			System.out.println(output);
 
		  } catch (Exception e) {
 
			e.printStackTrace();
