AngularJS and JEE

[Mahmoud Belhaoaune]

Hey guys!

This is a question that has been running back and forth through my mind for a while now.

Could angularJS be used in a Java web application (JSP & servlet based application per se)?

And if so, how could this be done?

Infact i tried to copy the content of an HTML page from an HTML file(that I'm using in an AngularJS app) into a jsp file.

The problem is that Eclipse doesn't approve the Angluar attributs (eg. ng-app ).

Thank you.

I am using AngularJS with JavaEE back end with spectacular success :) I am not using JSPs, but JAX-RS and static HTML templates. However, you could use JSPs to provide translations.

Witold Szczerba

Thank you Witold. Does anyone know how could this be done? (making JSP pages accept angularJS syntax.) :)

[Clint Checketts]

Have you tried adding the ng namespace and using the ng:app syntax?

(I have no idea myself on how this would be done)

Yup! Yeah I checked out on that. Nothing happens though. Man not a mere example on the net about something like this!

I think that using AngularJS with SP isn't that healthy. :D

I hope that somebody will inform me about this issue. :(

[Marco Rinck]

You don't find any examples as the best usecase for angularJS and JEE is using a JaxRS backend (in JEE container) and static html files without any Java Frontend technology like JSP, JSF whatsoever. 

Really, what do you need JSP for when you have a first class web app powered by angularJS?

[Clint Checketts]

The only reason I would use a JSP would be to bootstrap data into my page similar to the technique noted here: http://www.jvandemo.com/2013/01/10/how-to-bootstrap-data-in-angularjs/

I would only do it for the single base page. (not sure about Mahmoud's need though)

Hey!

Thank you all for your responses.

In fact I'm an intern in a company that works on JEE applications with JSP.

My coach wants to use some JS Framework such as Angular in their presentation layer.

He has no idea about it though. He asked me to do some research and to see if it would be suitable.

Well, it appears that using Angular with JSPs isn't advisable.

So guys, what do you propose as a framework that functions weel with JSPs?  :)

[Marco Rinck]

If I could choose freely for a new project/site I would trash JSP and choose JaxRS and a modern MVC Javascript framework like angularJS, backbone or whatever suits fit. 

If the team lacks the javascript know how I would trash JSP and choose JSF flavoured with PrimeFaces or RichFaces and some manual jQuery. Server-side frameworks don't work well with client-side MVC frameworks ihmo.  

I would NEVER choose JSP anymore. That is stoneage, really. 

Marco

[Mahmoud Belhaoaune]

Thanks Marco!

In fact, they asked another intern to try and integrate primefaces or icefaces in their projects.

Well, I guess this is the point then, finding a new way other than JSP. I'll suggest this alternative.

It is interesting and exciting. Hope I will make a point. :)

Hello, in the project I'm working on I'm going to draw charts and other graphics related to statistics. Would AngularJs be any good for this

kind of mission? (talking about using it with JaxRS of course)

Thanks.

I've started using in a pet project, but drop out all jsp in favor to pure html... I prefer static pages accessing dynamic data opposing dynamic pages... And for the eclipse errors, you can disable JSP syntax validation.

Cheers

I've written an Angular app that does just that here.

Try with this http://www.radcortez.com/java-ee-7-with-angular-js-part-1/, but not with JSP

I played around with JSP and AngularJS (inside Spring framework) .. you can simply declare your ng-app module in the html tag as follow.  If the code validation complaining about "ng-app", try to use "data-ng-app".  It is not eclipse that is complaining, HTML5 prefers the "data-" prefix.

<%@ include file="/WEB-INF/view/layout/header.jsp"%>

<!doctype html>

<html ng-app="accountDashboard">

<head>

<meta charset="ISO-8859-1">

<title>Insert title here</title>

<link href="${pageContext.request.contextPath}/static/css/main.css">

</head>

<body>

...

<script ... to import angularJS library>

</body>

</html>

Hi Guys,
could someone articulate to me the side effects / benefits of using JSP and Angular JS together?
I have a feeling this is not advisable, but dont know enough as to what could be amiss. Please help!

Thanks!

Hello,

There should not be any issue with using JSP with AngularJS as JSP can emit JavaScript and HTML. However, more relevant question is why would you want to use the JSP? What is the you can't do in HTML and plain JS that you want to bring in JSP? Please note JSP is a templating language and you cant write the web services in JSP. I use JSP in my project to generate the app.js dynamically as our project have multiple modules and each module is  OSGi bundle.

If you let us know what exactly you want to do, we can suggest you a better approach.

Regards,

Raj

Thank you Raj. That makes perfect sense. I currently am working on an existing java codebase (jsp templates and so on).
We were thinking of introducing Angular into this current application stack. I was trying to vet out the different approaches, either starting a whole new application from scratch (100%angular) talking to Rest services vs introducing angular in the current java / jsp codebase.
Just wanted to get your thoughts on these two approaches?

Thanks,
Paul

Hello Paul,

The approach I took is to use plain HTML/Angular along with RESTful services approach as I do not see JSP adding any value here. AngularJS is a client side MVC and I do not see need of another MVC at server side. However, you may need bit of JSP and may be a servlet (of course you can use a MVC if you want) to dynamic generate your home page (index.html). You may also need it if you want to inject a active profile of the user or if you want to authenticate without loading the index.html file.

Regards,

Raj

Raj,

Thanks a lot for answering my question.  I really needed a sounding board on this one!
 

Let me ask you another question. We are in the process of building a full blown news website (responsive site). We think Angular would be a great framework to build this in.

What do you think?  I feel like we dont see enough sites that are entirely built on Angular. is it bcos there is some pitfalls with Angular?

Thanks,

Paul

Hi All,

Hi All,

AngularJS is new web UI that may replace JSP. But before that few questions  how it can be used in secured web application. For example if any banking/financial application is built with AngularJS isn't there vulnerability exists which may cause future complexities.

How different secured REST call can be done or what are different security can be taken for web portal ?

Regards,

Jayanta P.

[Jayanta Pramanik]

Hi All,

Please let me clear more about security issues that may arise from Javascripts

OWASP recommended top 10 security measures. Javascript itself is very much vulnerable and prone to get XSS , CSRF attack ! Then Angular JS being  javascript in origin how can we protect data and implement OWASP guideline for our financial application. How can we encrypt param values if we want to do that while calling RESTservice from web portal to middleware backend.

Regards,

Jayanta P.

[mulianto]

Use https to encrypt everything on wire.

Its simple and proven ...

Hi,

actually any financial application has to be secured with respect to OWASP top 10 guidelines. How Angular JS can protect us from those vulnerabilities and how can we implement those OWASP recommended security measures.
