POST/PUT using CXF REST web service

[Sunny Bhandari]

I am writing REST web service with CXF framework and facing issues.
I have successfully issued GET and DELETE requests but not able to complete the POST and PUT requests.
See the code and let me know if I need to do something different for POST and PUT requests

The code and the exception that I get follows


OrderInfo.java - An interface for defining the webservice operation

package com.example.rest;

import javax.ws.rs.DELETE;
import javax.ws.rs.GET;
import javax.ws.rs.PUT;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;



@Path("/Order/")
public interface OrderInfo {

@GET
@Produces ("application/xml")
@Path("{orderId}")
public Order getOrder(@PathParam ("orderId") int officeId);

@GET
@Produces ("application/xml")
@Path ("All")
public OrderList getAllOrders();

@PUT
@Produces ("text/html")
@Path ("{order}")
public void addOrder(Order order);

@DELETE
@Produces ("text/html")
@Path ("{orderId}")
public void deleteOrder(@PathParam ("orderId") int officeId);

}

Order.java - A order object with getters/setters

package com.example.rest;

import javax.xml.bind.annotation.XmlRootElement;


@XmlRootElement(name = "Order")
public class Order {

private int orderId;
private String itemName;
private int quantity;
private String customerName;
private String shippingAddress;

public int getOrderId() {
	return orderId;
}
public void setOrderId(int orderId) {
	this.orderId = orderId;
}
public String getItemName() {
	return itemName;
}
public void setItemName(String itemName) {
	this.itemName = itemName;
}
public int getQuantity() {
	return quantity;
}
public void setQuantity(int quantity) {
	this.quantity = quantity;
}
public String getCustomerName() {
	return customerName;
}
public void setCustomerName(String customerName) {
	this.customerName = customerName;
}
public String getShippingAddress() {
	return shippingAddress;
}
public void setShippingAddress(String shippingAddress) {
	this.shippingAddress = shippingAddress;
}



}

OrderList.java - A list of Order objects

package com.example.rest;

import java.util.ArrayList;
import java.util.List;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement(name = "OrderList")
public class OrderList {

	@XmlElement(name = "order", required = true)
	List <Order> orders;

	public List<Order> getOrder() {
		if (orders == null) {
			orders = new ArrayList<Order>();
		}
		return this.orders;
	}
}

OrderInfoImpl.java - A concrete implementation of web service

package com.example.rest;

import java.util.ArrayList;
import java.util.List;

public class OrderInfoImpl implements OrderInfo {

	List <Order> list = new ArrayList<Order>();

	OrderInfoImpl(){
		Order order = new Order();
		order.setOrderId(1);
		order.setItemName("Soap");
		order.setQuantity(120);
		order.setCustomerName("Sandeep");
		order.setShippingAddress("Gurgaon");
		list.add(0, order);

		order.setOrderId(2);
		order.setItemName("Shampoo");
		order.setQuantity(50);
		order.setCustomerName("Sandeep");
		order.setShippingAddress("Gurgaon");
		list.add(1, order);
	}

	public Order getOrder(int orderId) {
		System.out.println("Inside the Get Order...");
		if (list.get(0).getOrderId() == orderId) {
			return list.get(0);
		} else if (list.get(1).getOrderId() == orderId) {
			return list.get(1);
		} else {
			return null;
		}
	}

	@Override
	public OrderList getAllOrders() {
		OrderList details = new OrderList();
		for(Order connection : list) {
			details.getOrder().add(connection);
		}
		return details;
	}
	
	@Override
	public void addOrder(Order order) {
		System.out.println("Inside the add order");
		/*Order order = new Order();
		order.setOrderId(3);
		order.setItemName("Scissor");
		order.setQuantity(1);
		order.setCustomerName("Sandeep");
		order.setShippingAddress("Gurgaon");*/
		list.add(2, order);
		
		OrderList details = new OrderList();
		for(Order connection : list) {
			details.getOrder().add(connection);
		}
		//return details;
	}
	
	@Override
	public void deleteOrder(int orderId) {
		System.out.println(orderId);
		System.out.println("Inside the delete order");
		
		if(list.get(0).getOrderId() == orderId) {
			list.remove(0);
		} else if (list.get(1).getOrderId() == orderId) {
			list.remove(1);
		} else {
			System.out.println("order not found");
		}
	}
}

Test.java to invoke the HTTP requests

package test;

import java.io.IOException;
import java.io.OutputStreamWriter;
import java.net.HttpURLConnection;
import java.net.URL;

public class Test {

	public static void main(String[] args) throws IOException {
		URL url = new URL("http://localhost:8080/resttest/services/Order/3");
		HttpURLConnection httpCon = (HttpURLConnection) url.openConnection();
		httpCon.setDoOutput(true);
		//httpCon.setDoInput(true);
		httpCon.setRequestMethod("PUT");
		OutputStreamWriter out = new OutputStreamWriter(
		   httpCon.getOutputStream());
		String message="{customerName:\"Sandeep\"}";
		System.out.println(message);
		out.write(message);
		out.flush();
		System.out.println(httpCon.getResponseCode());
		System.out.println(httpCon.getResponseMessage());
		out.close();
	}
}

The exception is:
