PrimeFaces vs RichFaces vs IceFaces

Page 1 of 2

In this tutorial we will compare three commonly used libraries which are used on the top of your JSF implementation. Richfaces, IceFaces and Primefaces.



Richfaces (http://www.jboss.org/richfaces) is JBoss JSF component framework.

Icefaces (http://www.icesoft.org) is Icesoft powerful Rich Internet application framework.

PrimeFaces (http://primefaces.org/) is Prime Technology Ultimate JSF Component Suite.



At first a premise: we don't pretend by any means to establish which is the best JSF component library: all these libraries have reached a mature release and they are widely and successfully adopted. Nevertheless we would like to point out which are, in our opinion, the coolest featurest of each of these component suites. This can be useful, especially if you don't have time to evaluate all of them.



1st Round: Components available

Richfaces

Richfaces, according to the showcase, contains about 39 core components and "variants" (11 core components, 6 panels, 9 tables-grid,1 tree, 4 toolbar,8 menu).

The number of components has not grown so much in the last years, however RF ships with a Component Development Kit (CDK) - a sub-project that allows you to easily create rich components with built-in Ajax support.



The significant features of the Component Development Kit (CDK) are: quick development (template based) start and declarative approach for a component development. It's only necessary to specify meta-data and a code specific for your component.



This seems a quite promising area, however it seems lacking some concrete examples of it through the net- the only one I have been available to find is http://blog.yonatan.me/2011/08/richfaces-cdk-tutorial-hello-world.html





Icefaces

Icefaces contains about 70 core components (http://wiki.icefaces.org/display/ICE/ICE+Components+Reference)



Additionally, you can plug-in the The ACE Components (ICEfaces Advanced Components) which are the next-generation of open source ICEfaces components. Currently featuring over 40 components including the ace:dataTable, the ACE Components utilize a blend of server-side and client-based rendering techniques to provide a rich, responsive user-experience with reduced network and server-processing requirements.



Primefaces

Primefaces features a rich set of 117 components (core components + variants) (http://www.primefaces.org/showcase/ui/home.jsf )which include, besides the standard set of components also many goodies like HtmlEditors, Charts, date Schedule and an Excel data exporter beside the others.

This suite uses behind the scenes, jQuery with its amazing widgets, plugins, themes and Ajax interactions. It's avoided on purpose other JS / UI frameworks in order to have a high compatibility between components. Primefaces is easier to skin since it is based on themeroller. It also has more built-in themes (about 25) than that is available in Richfaces and IceFaces.

If this does not seem enough, you can also look at PrimeFaces Extensions (http://code.google.com/p/primefaces-extensions/) which is an open source project licensed under Apache License V2. You can use it completely free in open source or commercial projects following the terms of the license.







2nd round: Easiness to get started:



Richfaces

Richfaces documentation does not contain a kickstart tutorial, the official docs is mostly focused on Maven which is a widely adopted standard, yet not the only one adopted by developers. Starting richfaces is not too complex even by adding file manually, as it requires the core library + UI library + 3 mandatory dependencies.

Optional third-party dependencies are needed for Bean validation (JSR-303), Push transport library - Atmosphere, push JMS integration, push CDI integration (CDI API and Implementation)



Icefaces

Icefaces: A getting started guide does exist. As far as the libraries are concerned, getting started with requires a set of core libraries and some dependencies (mostly Apache commons libraries)



? Primefaces

Primefaces does contains a getting started page. All you need to do is surfing to the download PrimeFaces, add the primefaces-{version}.jar to your classpath and import the namespace to get started. (Some dependencies are needed when dealing with excel/pdf and Fileupload). Cannot be easier than that.





3rd round: Documentation



Richfaces

Richfaces provides an online user guide which has been upgraded release by release while keeping the same schema. Unfortunately there are no additional tutorials about creating applications with Richfaces, some of them have been included in our site



Icefaces

IceFaces: The documentation is quite extensive as it includes a large set of tutorials, examples and also, recentely added, video tutorials. On the other hand, it's a bit annoying that you need registration to access anything (libraries, tutorials) and it's a bit confusing that you keep popping between icefaces.org and icesoft.org when using accessing the site.



Primefaces

Again, Primefaces provides the most pragmatic approach, delivering a complete user guide which is itself a complete e-book about the platform. Some additional resources are included as well on the site.



A last consideration about the forums: since also the forums contribute to the suite documentation, both RF and IF have a longer history on the web and thus deliver a greater set of questons and answers. Primefaces is a bit younger but growing.



Amount of topics discussed in official forums:

icefaces ~20000

richfaces ~20000

primefaces ~13000









4th Round: Open issues



Comparing issues between different products it's not so easy and could end up to comparing apples with oranges. We include a short view of all open issues leaving to the reader the final word ot it.



As you can see from the following picture, Richfaces and IceFaces both use JIRA to track their issues so they are substantially comparable. While the amount of open issues is a bit larger in Richfaces, if we weight them by priority, about 93% of Icefaces issues are labeled as "Major", while Richfaces exibits "just" a 64% of Major issues. On the other hand RF has recorded some more Critical issues.







Primefaces issues are tracked with google code and they are substantially less then the two other competitors (about 128 open issues), although, having a different lifecyle and number of releases, it's hard to compare them in an effective way.



(Note: we actually "denied" 5 stars to PF after finding an issue when delivering a large dataTable component. See performance tuning)

5th Round: core features



Here comes the real meat. As a matter of fact all 3 suites are JSF 2 compatible stacks. Besides this, every suite enhanced the basic JSF 2 features with some additions: Let's see them all:



Richfaces



On the the most interesting additions provided by RF is Ajax Push, named RichFaces Push. This allows you to perform realtime client side updates triggered via events from the server side. This is built around the Atmosphere framework which provides various transport mechanisms according to concrete browser support(Comet, HTML5 WebSockets). On the server events are managed by integrating Java Messaging Service (JMS). This provide enterprise level messaging integration all the way to the browser!



Usage of JMS at the back-end provides excellent integration with EE containers, and advanced messaging services. It also frees you from managing various entities at your business layer. If you are already using JMS for messaging in your application - you will just continue to send the same messages and you just need to to declare a4j:push at views which should listen that topics.



Another excellent addition provided by RF is an advanced queuing mechanism. JSF 2 provides a queuing mechanism out-of the box in order to sequence client side events with the built-in Ajax implementation. This queue is lacking in some very essential tuning options. The RichFaces a4j:queue provides these basic options in addition to other enhancements. There are two primary options available; 'requestDelay' and 'ignoreDupResponse'.



<h:panelGrid columns="2"> <h:outputText value="Request delay:" /> <h:inputText value="#{queueBean.requestDelay}" id="delay" converterMessage="Delay field should be a number (Demo input disabled till this resolved)"> <f:convertNumber integerOnly="true" /> </h:inputText> <h:outputText value="Ignore Duplicated Responces" /> <h:selectBooleanCheckbox value="#{queueBean.ignoreDupResponces}" /> </h:panelGrid>

<h:inputText value="#{userBean.name}"> <rich:validator/> </h:inputText>

Icefaces

Primefaces

<h:form> <h:outputText value="#{globalCounter.count}" styleClass=”display”/> <p:commandButton value="Click" actionListener="#{globalCounter.increment}" /> </h:form> <p:push onmessage="handleMessage" channel="counter" /> <script type="text/javascript"> function handleMessage(evt, data) { $('.display').html(data); } </script>







Finally, another RF cool thing is Client Validation feature allows you to have true client side validation without writing a single line of JavaScript! The standard JSF validators and JSR-303 (bean validation) constraints will be available on the client side just by addingto the desired inputs.A big plus of ICEfaces is not having to declare 'AJAX update regions' on the page. With ICEfaces, incremental ajax updates to the page are automatic, as is component interaction. Behind the scenes, ICEfaces employs a technique called '' rendering, or D2D for short, to achieve smooth incremental page updates to the browser. ICEfaces stores a copy of the DOM, which represents the browser presentation state in a tree structure, on the server. When the user interacts with the page, an Ajax call may be made to the server, resulting in a change to the application state, which in turn will cause the page to be re-rendered on the server.. These DOM updates, when received by the browser, are then evaluated and the browser DOM is reconstructed and updated with the necessary changes.The benefit of D2D in that when ever any field value changed the dependent field update automatically, you don’t need to explicitly refresh the dependent block this saves lot of code and complexity an other important benefit we get is optimized server to client data transfer, only changed data is transfered from server to client.Finally, also IF has a built-in Ajax Push, (named) which adds the ability to push out ajax updates to groups of clients based on a server event, without the clients needing to request the update.ICEpush relies on Servlet 3.0 standard ARP APIs. If they are not present in the deployment environment, normal thread blocking connections are used.For clustered and high-availability deployments of Ajax Push-enabled applications theis required. It manages asynchronous blocking connections across the cluster and performs seamless fail over for mission-critical, high-availability deployments. EPS is available in ICEfaces Enterprise Edition.Although the strongest point of PrimeFaces is the component set, it also features various Add-ons simplifying Web and especially JSF development. Since Primefaces has in its DNA jQuery, most of this additions are based as Javascript call back methods.One cool PF addition is thefeature which uses facets to represent the request status. Most common used facets are start and complete. Start facet will be visible once ajax request begins and stay visible until it’s completed.Once the ajax response is received start facet becomes hidden and complete facet shows up.Also PF has got its Ajax push, called, which enables implementing push based use-cases powered by WebSockets using atmosphere.Here's an example:is a PrimeFaces component that handles the connection between the server and the browser, it has two attributes you need to define. The first one (onmessage) defines the callback method, which is implemented as a javascript function.
