RESTful services with jQuery and Java using JAX-RS and Jersey

NOTE: This is the Java version of this article and its companion app. A PHP version is available here.

This is a more in depth version of my previous post on the same topic. The previous article only covered the HTTP GET method for building RESTful services. This article (and its new companion app) provides an example of building a complete RESTful API using the different HTTP methods:

  • GET to retrieve and search data
  • POST to add data
  • PUT to update data
  • DELETE to delete data

The application used as an example for this article is a Wine Cellar app. You can search for wines, add a wine to your cellar, update and delete wines.


You can run the application here. The create/update/delete features are disabled in this online version. Use the link at the bottom of this post to download a fully enabled version.

The REST API consists of the following methods:

Method URL Action
GET /api/wines Retrieve all wines
GET /api/wines/search/Chateau Search for wines with ‘Chateau’ in their name
GET /api/wines/10 Retrieve wine with id == 10
POST /api/wines Add a new wine
PUT /api/wines/10 Update wine with id == 10
DELETE /api/wines/10 Delete wine with id == 10

 

Implementing the API using JAX-RS

JAX-RS makes it easy to implement this API in Java. You simply create a class defined as follows:

package org.coenraets.cellar;

@Path("/wines")
public class WineResource {

	WineDAO dao = new WineDAO();

	@GET
	@Produces({ MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML })
	public List<Wine> findAll() {
		return dao.findAll();
	}

	@GET @Path("search/{query}")
	@Produces({ MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML })
	public List<Wine> findByName(@PathParam("query") String query) {
		return dao.findByName(query);
	}

	@GET @Path("{id}")
	@Produces({ MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML })
	public Wine findById(@PathParam("id") String id) {
		return dao.findById(Integer.parseInt(id));
	}

	@POST
	@Consumes({ MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML})
	@Produces({ MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML })
	public Wine create(Wine wine) {
		return dao.create(wine);
	}

	@PUT @Path("{id}")
	@Consumes({ MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML})
	@Produces({ MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML })
	public Wine update(Wine wine) {
		return dao.update(wine);
	}

	@DELETE @Path("{id}")
	@Produces({ MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML })
	public void remove(@PathParam("id") int id) {
		dao.remove(id);
	}
}

Quick look at the JAX-RS annotations used in this class:

  • @GET, @POST, @PUT, @DELETE: HTTP method the class method responds to.
  • @Path: path the method responds to.
  • @Consumes: type of data the method can take as input. The data will automatically be deserialized into a method input parameter. For example, you can pass a wine object to the addWined() method either as JSON or XML. The JSON or XML representation of a new wine is automatically deserialized into the Wine object passed as an argument to the method.
  • @Produces: One or more response content type(s) the method can generate. The method’s return value will be automatically serialized using the content type requested by the client. If the client didn’t request a specific content type, the first content type listed in the @Produces annotation will be used. For example, if you access http://coenraets.org/rest/wines, you get a list of wines represented as JSON because it is the first content type listed in the @Produces annotation of the findAll() method.

The jQuery client below sends data to the server using JSON (addWine() and updateWine() methods).

The approach you use to actually retrieve the data is totally up to you. In this example, I use a simple DAO, but you can of course use your own data access solution.

Testing the API using cURL

If you want to test your API before using it in a client application, you can invoke your REST services straight from a browser address bar. For example, you could try:

You will only be able to test your GET services that way, and even then, it doesn’t give you full control to test all the content types your API can return.

A more versatile solution to test RESTful services is to use cURL, a command line utility for transferring data with URL syntax.

For example, using cURL, you can test the Wine Cellar API with the following commands:

  • Get all wines returned as default content type:
    curl -i -X GET http://localhost:8080/cellar/rest/wines
    
  • Get all wines returned as xml:
    curl -i -X GET http://localhost:8080/cellar/rest/wines -H 'Accept:application/xml'
    
  • Get all wines with ‘chateau’ in their name:
    curl -i -X GET http://localhost:8080/cellar/rest/wines/search/chateau
    
  • Get wine #5:
    curl -i -X GET http://localhost:8080/cellar/rest/wines/5
    
  • Delete wine #5:
    curl -i -X DELETE http://localhost:8080/cellar/rest/wines/5
    
  • Add a new wine:
    curl -i -X POST -H 'Content-Type: application/json' -d '{"name": "New Wine", "year": "2009"}' http://localhost:8080/cellar/rest/wines
    
  • Modify wine #27:
    curl -i -X PUT -H 'Content-Type: application/json' -d '{"id": "27", "name": "New Wine", "year": "2010"}' http://localhost:8080/cellar/rest/wines/27
    

The jQuery Client

Accessing your API through cURL is cool, but there is nothing like a real application to put your API to the test. So the source code (available for download at the end of this post) includes a simple jQuery client to manage your wine cellar.

Here is the jQuery code involved in calling the services:

function findAll() {
	$.ajax({
		type: 'GET',
		url: rootURL,
		dataType: "json", // data type of response
		success: renderList
	});
}

function findByName(searchKey) {
	$.ajax({
		type: 'GET',
		url: rootURL + '/search/' + searchKey,
		dataType: "json",
		success: renderList
	});
}

function findById(id) {
	$.ajax({
		type: 'GET',
		url: rootURL + '/' + id,
		dataType: "json",
		success: function(data){
			$('#btnDelete').show();
			renderDetails(data);
		}
	});
}

function addWine() {
	console.log('addWine');
	$.ajax({
		type: 'POST',
		contentType: 'application/json',
		url: rootURL,
		dataType: "json",
		data: formToJSON(),
		success: function(data, textStatus, jqXHR){
			alert('Wine created successfully');
			$('#btnDelete').show();
			$('#wineId').val(data.id);
		},
		error: function(jqXHR, textStatus, errorThrown){
			alert('addWine error: ' + textStatus);
		}
	});
}

function updateWine() {
	$.ajax({
		type: 'PUT',
		contentType: 'application/json',
		url: rootURL + '/' + $('#wineId').val(),
		dataType: "json",
		data: formToJSON(),
		success: function(data, textStatus, jqXHR){
			alert('Wine updated successfully');
		},
		error: function(jqXHR, textStatus, errorThrown){
			alert('updateWine error: ' + textStatus);
		}
	});
}

function deleteWine() {
	console.log('deleteWine');
	$.ajax({
		type: 'DELETE',
		url: rootURL + '/' + $('#wineId').val(),
		success: function(data, textStatus, jqXHR){
			alert('Wine deleted successfully');
		},
		error: function(jqXHR, textStatus, errorThrown){
			alert('deleteWine error');
		}
	});
}

// Helper function to serialize all the form fields into a JSON string
function formToJSON() {
	return JSON.stringify({
		"id": $('#id').val(),
		"name": $('#name').val(),
		"grapes": $('#grapes').val(),
		"country": $('#country').val(),
		"region": $('#region').val(),
		"year": $('#year').val(),
		"description": $('#description').val()
		});
}

    The best Jersey Rest + JQuery example i´ve seen so far… still searching for an easy solution to solve the “cross-site” – problem… some of yours have any idea what to change on server-side in case of running the JQuery – Client on a different webserver? (eg. webservice is running on http://10.10.10.1:8080/cellar, JQuery – client is running on http://10.10.20.1:8080/index.html)

    • Kenny May 24, 2012 at 9:33 am #

      Hi Gerd
      I’ve been running into the cross-site problem aswel and after a lot of research found a few solutions:

      - JSON-P can be used for GET requests ONLY. Also note that it is not very secure.
      - CORS is probably the best way other then using a proxy. (Basically you add the correct headers to your requests and replies.)

      Hope this helps.
      Cheers
      Kenny

      Hi,

      “(Basically you add the correct headers to your requests and replies.)”
      below is an example how to add the header to your response:

      @GET
      @Produces(MediaType.APPLICATION_JSON)
      public Response getFooBar() {
      String json = “”{foo: \”bar\”}”;
      return Response.ok(json).header(“Access-Control-Allow-Origin”, “*”).build();
      }

    Hi,

    At first let me thank you for putting the nicest example of Webservice that is done using REST/Jersey.
    However, my question is not regarding the service, but in database connectivity. You have used mysql as your database and so on, I would like to use Oracle, but the problem with the connection string,
    my database name is, Orcl, name: system and password: sa1234, but don’t what would be the syntax for putting the data.

    Hi,
    Thanks for a simple and elegant example for RESTful service. I have one question,
    what if the ‘Wine’ object is modified later and a group of people need the initial version of ‘Wine’ and a different group need the newer version of ‘Wine’?
    Bottomline, how to deal with versions of ‘Wine’ object? I hate to use query params, that may not be valid for POST, I might use PUT instead, still not an elegant solution.
    Your advise please.

    Thanks much,
    Tamil

    I can’t make this example run beyond the static index.html and main.js. I tried in Eclipse and then in NetBeans with both Tomcat and Glassfish. There seems to some errors in terms of URIs for the RESTFul Webservices. Context was not setup in Glassfish and Tomcat is also not going any further.
    I like the example and there is no compilation errors but some how it needs a lot of work around to make it run end to end.

    Nice post.

    If you wanted to have a slightly more ‘RESTful’ API you could implement the search functionality with query params on the Wine resource like so:

    /api/wines?name=*Chateau*

    Style wise /api/wines/search is more of an RPC approach then a RESTful one.

    is it possible to send custom object as a @Pathparam using get method and i need json as output using RESTFUL.

    I mean instead of sending all the parameters URI like —-> custom/1/aaa/addr shall we custom/pojo

    Client Side:

    class Pojo{
    int id=1;
    String name=”aaa”;
    String addr=”addr”;
    //setter & getters

    }

    Main class:

    public static void main(String… a)
    {
    Pojo pojo = new Pojo();

    System.out.println(service.path(“rest”).path(“custom/pojo”).accept(MediaType.APPLICATION_JSON).get(String.class));
    }

    server side:

    @Path(“/custom”)
    class Custom
    {
    @GET
    @Produces({ MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON })
    @Path(“{pojo}”)
    public Pojo getJsonOutput(@PathParam(“pojo”) Pojo p) {
    if(1==p.getId() && “aaa”.equals(p.getName()) && “addr”.equals(p.getAddr())

    return new Pojo();

    else

    return null;
    }
    }

    class Pojo{
    int id=1;
    String name=”aaa”;
    String addr=”addr”;
    String firstName=”aaa”;
    String lastName=”bbb”;
    String firstAddr=”ccc”;
    String lastAddr=”ddd”;
    String mobnumber=”123457896″;

    //Setters & Getters

    }

    return dao.create(wine1);
    }

    [ "B", "Internet Explorer 5.0", "Win 95+", 5, "C" ] ] }

    Your code is working fine but if i separate the web service code from the front end, the response from the web service in the JSON format is not coming. my requirement is to test if web service and front end projects are deployed on different servers, then how to make them work. Note: html page is able to consume webservice but response is not getting rendered on the page. Please help me.

    Thanks in advance.

    Hi Alex,

    Thanks for the post.With your example i am able to run Get Request in cross-site.but still facing problem to save data through POST request.Below is the code which i changed to run GET request for cross-site problem.
    @GET
    @Produces({ MediaType.APPLICATION_JSON })
    public Response findAll() {
    System.out.println(“findAll”);
    return Response.ok(dao.findAll()).header(“Access-Control-Allow-Origin”, “*”).build();
    }
    but POST is still not working with this change. Please help.

    Fantastic blog! Do you have any tips for aspiring writers?
    I’m planning to start my own site soon but I’m
    a little lost on everything. Would you recommend starting with a free platform like WordPress or go for
    a paid option? There are so many options out there that I’m completely confused ..
    Any tips? Thanks a lot!

    I found strange issue – ‘wineDAO’ is allocated (by calling ‘Wine wine = new Wine();’ in WineResources.java file) on every request by ‘curl’ utility.

    I found it by debugging the code in Eclipse.
    Please take a look at the my very basic version (copy-paste by 99%) that has this issue:
    https://github.com/kostaz/WineCellar

    The commit that show the problem is “5700684 Added Java server side – not all works”.

    Below is the Eclipse call stack.
