Java EE 7 with Angular JS – Part 1

posted by Roberto Cortez on

Today’s post will show you how to build a very simple application using Java EE 7 and Angular JS. Before going there let me tell you a brief story:

I have to confess that I was never a big fan of Javascript, but I still remember the first time I have used it. I don’t remember the year exactly, but probably around mid 90’s. I had a page with 3 frames (yes frames! remember those? very popular around that time) and I wanted to reload 2 frames when I clicked a link on the 3rd frame. At the time, Javascript was used to do some fancy stuff on webpages, not every browser have Javascript support and some even required you to turn it on. Fast forwarding to today the landscaped changed dramatically. Javascript is a full development stack now and you can develop entire applications written only in Javascript. Unfortunately for me, sometimes I still think I’m back in the 90’s and don’t give enough credit to Javascript, so this is my attempt to get to know Javascript better.

Why Java EE 7?
Well, I like Java and the new Java EE version is pretty good. Less verbose and very fast using Wildfly or Glassfish. It provides you with a large set of specifications to suit your needs and it’s a standard in the Java world.

Why Angular JS?
I’m probably following the big hype around Angular here. Since I don’t have much experience with Javascript I don’t know the offers very well, so I’m just following advice of some friends and I have also noticed a big acceptance of Angular in the last Devoxx. Every room with an Angular talk was full, so I wanted to give it a try and found out for myself.

The Application

For the application, it’s a simple list with pagination and a REST service that feeds the list data. Every time I start a new enterprise project it’s usually the first thing we code: create a table, store some data and list some random data, so I think it’s appropriate.

The Setup

The Code (finally!)

Backend – Java EE 7

Starting with the backend, let’s define a very simple Entity class (some code is omitted for simplicity):

If you’re not familiar with Java EE JPA specification, this will allow to model an object class into a database table by using the annotation @Entity to connect to the database table with the same name and the annotation @Id to identify the table primary key.

Following by a persistence.xml:

Two of my favourite new features on Java EE 7: now you can run sql in a standard way by using the properties javax.persistence.schema-generation.* and it also binds you to a default datasource if you don’t provide one. So for this case, it’s going to use the internal Wildfly H2 database for our application.

Finally, to provide the list data we need to query the database and expose it as a REST service:

The code is exactly as a normal Java POJO, but using the Java EE annotations to enhance the behaviour. @ApplicationPath("/resources") and @Path("persons") will expose the REST service at the url yourdomain/resources/persons, @GET marks the logic to be called by the http GET method and @Produces(MediaType.APPLICATION_JSON) formats the REST response as JSON format. Pretty cool with only a few annotations.

To make it a little easier to exchange the needed information for the paginated list, I have also created the following wrapper class:

And we are done with the backend stuff.

UI – Angular JS

To display the data we are going to use Angular JS. Angular extends the traditional HTML with additional custom tag attributes to bind data represented in Javascript variables by following a MVC approach. So, lets look to our html page:

Apart from the Javascript and CSS declarations there is very little code in there. Very impressive. Angular also have a wide range of ready to use components, so I’m using the ng-grid to display the data and UI Bootstrap that provides a pagination component. The ng-grid also have a pagination component, but I liked the UI Bootstrap pagination component more.

There is something still missing. The Javascript file where everything happens:

The Javascript code is very clean and organised. Notice how everything gets added to an app controller, allowing you to have multiple separation of concerns on your business logic. To implement the required behaviour we just need to add a few functions to refresh the list by calling our REST service and monitor the grid data to refresh the view. This is the end result:

Java EE 7 - Angular - List

Next Steps:

For the following posts related with these series, I’m planning to:


You can clone a full working copy from my github repository and deploy it to Wildfly. You can find instructions there to deploy it. Should also work on Glassfish.

Java EE – Angular JS Source

In the meanwhile I have updated the original code with the post about Manage Javascript dependencies. Please, download the original source of this post from the release 1.0. You can also clone the repo, and checkout the tag from release 1.0 with the following command: git checkout 1.0.

I hope you enjoyed the post! Let me know if you have any comments about this.

    nice start , i wish you should have used angular dart( instead of angular js, Angular dart based is based on dart (more structured lang like java) ,Java developer can pick this lang in hours .Personally i hate javascript

    if(“I am dumb ,are You also dumb?”) {
    alert(“Truth is broken!”);

    and in NextSteps :
    I wish there is security added REST API’s πŸ™‚

      Don’t worry. I’m also planning to have something build in Dart πŸ™‚

  2. ReplyTundeMichael

    Don’t you need to have the JAXB annotation @XmlRootElement on the entity for entity to JSON conversion?

    • ReplyRoberto Cortez

      Hi TundeMichael,

      JAXB is Binding for XML and does not include JSON. Actually, there is no equivalent no JAXB in Java EE 7, probably only in Java EE 8.

      Anyway, you don’t need the annotation to produce the JSON response in the REST service.

      • ReplyDave

        I think TundeMichael is correct, you need to have @XmlRootElement on your resource classes. JAXB annotations are used for JSON and XML.

        From Oracle’s own mouth:

        • ReplyDave

          Ok…played around a little more. So it’s not necessary in my simple test, but the JAXB annotations *do* pertain to JSON format.

          • Roberto Cortez

            Hi Dave, thank your for your comment. What I meant was that there is no specification for the JSON Binding in Java EE 7, but it’s possible to do it and some technologies reuse the same JAXB annotations. I’m just not sure if when the new specification for JSON-B if the spec experts are going to add or reuse the same annotations.

    Hi Roberto,

    Could you provide the working demo of the above example?

    I am working on the same scenario of using angular-ui-bootstrap pagination with ng-grid, but that ain’t working.

    only the first,previous,next,last are displayed, no page numbers are displayed πŸ™

    Thanks a lot Roberto for this post .
    I need to know if JSF can be combine with angularJS , because i have seen a post that provide informations about AngularFaces or something like this .And if it’s not possible to make this combination works , wath’s the alternative way to build some java ee application with angularJS and a java ee framework(Spring for example).

  7. ReplyRoberto Cortez

    Hi Rsone. Thank you so much for your feedback. I don’t see any reason for it to not combine. but there might be a lot of work to integrate both technologies. I’m not familiar with the AngularFaces project, but seems like a start. Spring and Java EE are two different technologies, you can also mix the two, but what are you trying to accomplish exactly?

  8. Replymetao

    I want to know how did you composed Node.js with JavaEE? This is cool if we do so.

    • ReplyRoberto Cortez

      Hi metao, Thank you for your comment. I’m not quite sure what do you mean with composed. Can you clarify me please?

  9. ReplyThomas Mundt

    Hi Roberto,

    I am on a webapplication project. With that, I try to achieve combining JSF 2.1, AngularJS and using its REST-API.

    Altough I have learnt JSF is not following REST-Architecture at all, I am trying to achieve invoking REST-calls to JSF via AngularJS-http-service.

    Somehow, using those calls does not work if invoked within AngularJS, as I am getting the error that the server could not find the resource. Invoking those rest services within a browser by inputing the URL directly shows the desired information.

    Do you hava a clue?

    Yours, Tom

    • ReplyRoberto Cortez

      Hi Thomas,

      Thank you for your comment. I see no reason why it shouldn’t work. Without looking into the code its hard to diagnose the problem, but can you confirm that Angular is calling the correct URL for the REST service?


  10. Replyindy2005


    Whats the approach for testing the angular front end generally in this setup. I have an application using Spring, Spring Data Repositories and JAX-RS.

    The web application is bootstrapped in the usual way via web.xml to enable repository package scanning etc.

    But I am uncle unclear on how I would go about testing the Angular front end in what is not a pure javascript project?

    Any advice appreciated.



    • ReplyRoberto Cortez

      Hi indy2005,

      This is something that I’m going to write about in one of my following pots regarding Angular, but probably is better to mock your server side and focus only on the client.

      Is there any reason for you to have the Spring part up and running for the tests?

      Yes, it’s possible. They are two separate technologies. It just happens that I was experimenting with Java EE 7 and I wanted to use the latest version. You shouldn’t have any problems using it with EE 6.

    Hello , thank you very much , i’m beginner in java ee , when you say that in back-end you used : java ee 7 , you mean EJB and JPA ?
    and front-end , you used HTML5 and angular JS because you separated back and front ? with API Rest
    Please your answer will help me a lot ..

    • ReplyRoberto Cortez

      Hi Kimosaki,

      Yes, so EJB and JPA are just two specifications that belong to a wider API known as Java EE. I’ve also used JAX-RS specification to provide REST services. For the front-end I’ve used HTML, JS and Angular. All of the technologies reside in the same project


  25. ReplySudhir

    It looks like you used EJB. So to run this example, I must have to install an application server. right? I will not be able to run using Tomcat?

      Yes, but if you want to use Tomcat, you can use TomEE. It allows you to run Java EE in Tomcat.

    • ReplyRoberto Cortez

      Hi Fivalo,

      Thank you for your feedback.

      You could definitely create 2 projects, one for the Java EE side and another for the Angular side. These would separate your concerns and allow you to focus in one or another. The Angular project should be a Web Project.


  33. ReplyZelarith

    Hi Roberto.

    Thanks for the sources and the tutorial !
    My JEE was a bit rusty so the tutorial was a bit too fast on the backend part for me so the sources came in handy !

    I tried to open your project using the NetBeans IDE. I can run the project and no error or warnings shows up. However, when the page opens up, the person list is empty, and I can’t save any new person…
    When I try to save some new person, I have a “There was a problem in the server!” div that appears on top of the screen, but no error message.

    I’ve seen that you are using the default data source, so I don’t understand what problems could show up… Any idea of what is the problem or even just a hint of what I could change in the code to have an actual error logged in the browser or server console so I could have more informations?

    Thanks !
    – Zelarith

    • ReplyZelarith

      Uh, actually, I do have errors in the browser console (bear with me, I’m not using my usual web browser !)
      Seems I get some code 500 – Internal error from the backend

    • ReplyZelarith

      So… I checked glassfish server console.
      I get a Warning logged that looks more like an error to me :

      “StandardWrapperValve[]: Servlet.service() for servlet threw exception
      java.lang.NoClassDefFoundError: Could not initialize class org.eclipse.persistence.jaxb.BeanValidationHelper
      at […] ”

      I get it once per call to the backend (so whenever I reload the page or try to save a new person)

    • ReplyZelarith

      Aaaaaaand I now remember why I hated GlassFish in my school days… Apparently, this is a GlassFish 4.1.1 issue (GlassFish 4.1.1 was included in the JEE NetBeans bundle)

      If anyone were to end up with this problem too, well, the only solution is to go back to Glassfish 4.1(.0) or maybe upgrade it to whatever is the current most recent version when you read this (though I most certainly can’t ensure you that it will work on said version)

      Well, maybe I should also give WildFly a try, but that’s an adventure for another day…
