Primefacs icefaces usage

#Primefacs icefaces usage update#

Once you start to use the components in PrimeFaces for things other than trivial showcase examples you quickly run into a lot of problems and limitations (I'm grateful for PrimeFaces, but thought I would provide a little constructive feedback).One of the questions from the above dialog that we (ICEsoft) have perhaps not fully addressed already is why we felt it necessary to fork the PrimeFaces project in the first place. I also hope that 2.2/2.3 focuses more on fixing up bugs and making the component library more useable in general. Post on Primefaces forum that is quite revelent : Thanks Mathieu for correcting the spelling of the article! ) ĭear Icefaces, Primefaces and Richfaces users, if you see some improvements please post a comment. If a winner should be decided it would be Richfaces since I have been quite disappointed by Primefaces. Richfaces is between Primefaces and Icefaces closest to Primefaces. Icefaces has clearly the worst performance on datatable on all test. Primefaces has the best datatable implementation although buggy (I hope Primefaces 2.2 will correct all the issues). To be complete the generic components (tab, tree.) have to be tested too in order to make a robust conclusion. Richfaces : 9400 requests ~900MB : ~100KBĬonclusionThe page used for the test is quite simple and does not reflect a real page nor the global performance of these frameworks.I took the JVM memory consumption and the number of requests done : You can basically have three time more users with Primeface than Icefaces (considering it is growing lineary)īecause Icefaces OOM my JVM very quickly without a cookie manager I did a very simple calculation on session size. Test setup : Core 2 Duo 3Ghz 64bits, 2GB dedicated to the JVM. Server loadI have created a simple unit test which executes 10 concurrent threads with a cookies manager. So the question is, why does it do that when we don't need them?

#Primefacs icefaces usage update#

Knowing that I put an id only on the components i needed to update that means JSF autogenerate the other Ids by itself. The table contains ids and classes only on rows.īut what if the data changes on the server side (delete or add) ? An user action on the paginator doesn't update it. The paginator is updated on the client side. The Icefaces paginator block is quite big, more than the datatable block. The table contains ids and classes on all cells. Icefaces and Richfaces send the paginator and the table. Richfaces can gain 80KB by using JQuery min and be below 200KB. Icefaces and Richfaces don't used minified JS. Creating an unit test with HtmlUnit is quite simple and I did not met issue requesting Icefaces, Primefaces and Richfaces for the purpose of this article. Page size benchmarkI'm measuring the page size and the ajax response size with HtmlUnit. The datable is binded to an ajax paginator which display books 15 by 15. Test setupThe datatable will display a list of books with 3 columns : ISBN, author and title. I will focus on efficiency : page size, ajax request/response size, server load, and not on features. In this article I will bench the datatables of 3 JSF2 components frameworks :

Web development architecture - what to use?

I am fluent in back-end Java. I know JavaScript as well, and I can create a web site, but will not be pretty, as I am not a designer.

I am not fluent in CSS, bootstrap, although I can do html and JavaScript.

I would like to create a pretty, modern web site.

Currently, I have a web site that I can’t update. It was created in Apple iWeb, which has been discontinued by Apple.

I also have a couple of web apps in JSF / PrimeFaces which work fine and I’d like to keep as unchanged as possible.

Of course I could use SquareSpace, Webflow, Weebly, etc. but wouldn’t this put me in a position again where I deeply depend on a website builder.

Requirements:

Site Content is not tied to template (written in AsciiDoc or Markdown)

Site Content is not written in html/xhtml and is easy to update

Integrate with JSF / PrimeFaces web apps with the same template somehow (iframe?)

Automatic NavBar, Headers/Footers, content tree/breadcrumbs, accessibility, modern web features, etc. that comes with a modern template

What I tried:

Jekyll w/Made Mistakes template and Netlify - I like that approach, but how to integrate with JSF web apps (iframe maybe?)?

Drupal (seemed slow) didn’t get far into that

JSF / Primefaces has great templates, but I would have to write content in XHTML, which I do not want, and it doesn’t have an automatic NavBar that I know of

What I envision a good solution to be:

Something that is Java /JSF based, or can integrate with it

I can create content in Markdown or Asciidoc (NOT xhtml)

Has “made mistakes” template or similar pretty web site

XXX is a PrimeFaces template that has NavBar capability, and YYY is Java CMS that supports Markdown and Asciidoc

Answers I do not want:

Use (Angular/React/Vue).js or other generic web framework - I already have my preferences for those, and that doesn’t answer the requirements above

Use a (generic CMS) - I would need specifics, i.e. use Drupal with XXX Co NavBar plugin, Asciidoc plugin and Java under GraalVM w/ZZZ plugin

Thank you very much for your advise!

Erstellen einer Pagination in Java Server Faces 2.2

In diesem Tutorial möchte ich beschreiben wie man eine Pagination in eine JavaServerFaces Tabelle implementiert.

Pagination in einer JSF DataTable Sicherlich kann man hierzu ein JSF Framework wie Primefaces zu Hilfe nehmen, jedoch bringt dieses für "nur" die Funktion der Pagination einen sehr großen Overhead mit. Als Basis dieses Tutorial nutze ich ein einfaches JSF Projekt mit einer Statischen Liste von Objekten (quasi ohne Datenbankanbindung). Das leere Projekt kannst du dir unter folgendem Link herunterladen oder folgst dem Tutorial Erstellen eines JavaServerFaces 2.2 Projektes mit Eclipse & Apache Maven, dort habe ich beschrieben wie du dir ein Projekt mit Apache Maven und Eclipse einrichten kannst.

JSF DataTable

Für die Darstellung einer Tabelle in JSF gibt es zwei Mögliche Komponenten, einmal das PanelGrid und einmal die DataTable. In diesem Tutorial verwende ich die Komponente DataTable. Zunächst einmal benötigen wir eine kleine Seite welche unsere DataTable anzeigen soll (und zusätzlich eine passende Überschrift). JSFPagination

JSFPagination

... Die DataTable soll später Daten mit dem Server austauschen / Aktionen ausführen, daher muss diese in eine Form gekapselt werden. Definieren der DataTable Die DataTable wird mit dem JSF Tag h:datatable eingeleitet und geschlossen. In dem Attribut "value" wird die Liste mit den Objekten für die Tabelle hinterlegt und über das Attribut "var" können wir dann beim rendern der Tabelle auf die Objekte zugreifen und durch ggf. weiteren Code die Tabelle manipulieren. Als nächsten Schritt definieren wir wieviele Zeilen in der Tabelle aufeinmal angezeigt werden sollen. Dieses erledigen wir indem das Attribut "rows" verwendet wird. Nun könnte man als Wert einfach eine Zahl einfügen jedoch benötigen wir diesen Wert später für unsere Pagination daher ist es besser diese Zahl in einer Bean zu speichern. Eigentlich ist diese Zahl fix und wir könnten daraus eine Konstante via "private static final" machen, jedoch könnten wir dann nicht mehr auf diese in unsere XHTML zugreifen denn nach der Java Beans Konversation benötigen wir Getter und Setter. Und Getter und Setter an einer Konstante klingt nicht nur komisch sondern ist es auch. Daher wird dieses ein einfaches Feld in der Bean. Nun fehlt noch das wichtige Attribut ab welchem Index diese Zeilenzahl gelten soll. Dieses wird über das Attribut "first" gelöst. D.h. der Wert von "first" repräsentiert den Index aus der Liste der Objekte. Der Wert beginnt wie üblich bei der java.util.List bei 0. Nun können wir die Tabelle aufbauen. Mein Testobjekt hat zwei Felder "ID" und "Text". ID #{tblEntry.id} Text #{tblEntry.text} Mit dem JSF Tag "h:column" wird eine Spalte definiert. Zusätzlich können wir mit 'f:facet name="header"' definieren wie der Spaltenkopf beschrieben ist. In diesem Beispiel steht nur der Text "ID" im Spaltenkopf. In einer echten JSF Anwendung würde man nun diesen Text internationalisieren (mehrsprachig anbieten). Der Wert der Zelle wird durch "#{tblEntry.}" eingeleitet. (Es ist nicht nötig den Wert in ein "h:outputText" zu stecken.) Tabellenfußzeile für die Pagination Neben den Bereits genannten Tabellenkopf gibt es auch eine Fußzeile welche man definieren kann. Und genau in diese Zeile möchten wir unsere Pagination darstellen. Dazu müssen wir zunächst einmal diese Zeile wie folgt definieren. ... Damit wir später die Schaltflächen und die Auswahlliste sauber ausrichten können müssen wir diese in ein "h:panelGrid" stecken. Dieses bewirkt das wir in unsere Fußzeile eine zusätzliche Tabelle erhalten welche über die gesamte Breite der äußeren Tabelle geht. Schaltflächen Weiter & Zurück Für die einfache Seitennavigation reichen schon die zwei Schaltflächen "Weiter" & "Zurück" aus. Für die Darstellung der Schaltflächen benötigen wir 2 Attribute einmal "value" für den Text und einmal für die Sichtbarkeit "rendered". Das Attribut "action" definiert eine Methode in unserer Java Bean welche ausgeführt werden soll wenn die Schaltfläche betätigt wird. Auswahlliste für die Seiten Um jedoch auch auf bestimmte Seiten zuzugreifen benötigen wir zusätzlich zbsp. eine Auswahlliste welche zwischen den beiden Schaltflächen angezeigt werden soll. Für die Darstellung einer Auswahlliste benötigen wir das JSF Tag "h:selectOneMenu". Dieser enthält ähnlich wie die DataTable das Attribut "value" jedoch ist dieses nicht eine Liste sondern der ausgewählt Wert aus der Liste! Die Einträge in dieser Liste werden entweder selber mit "f:selectItem" oder "f:selectItems" definiert Da wir ggf. eine undefinierte Liste von Werten haben benötigen wir den zuletzt genannten Tag "f:selectItems". In dem Attribut "value" wird unsere java.util.List mit den Seitennummern stecken und das bereits bekannte Attribut "var" enthält einen Index auf den aktuellen Wert. Die Attribute "itemLabel" für das sichtbare Textfeld in der Auswahlliste und "itemValue" für den Wert welcher später in der Java Bean verarbeitet werden soll, werden aus dem Wert der aktuellen Iteration befüllt. Damit die Änderung beim auswählen eines Eintrages sofort sichtbar werden benötigen wir eine Aktion dieses wird durch "f:ajax" realisiert. Das Attribut "listener" enthält eine Methode in der Java Bean welche ausgeführt wird. Nach Abschluss dieser Aktion soll dann die Komponente im Attribut "render" aktualisiert werden, der Wert "@form" definiert das die äußere Form sich aktualisieren soll und somit alle darin befindlichen Komponenten (Tabelle, Schaltfläche, Auswahlliste etc.). CSS Style Für das Styling von HTML Komponenten benötigen wir eine CSS Datei diese Datei wird in JSF im Pfad "webapp\resources\css\" abgelegt und im Kopfbereich der XHTML Datei wiefolgt eingebunden: DataTable Damit wir nicht nur eine platte Tabelle erhalten, können wir der DataTable einige Attribute setzen damit die Datenzeilen der Tabelle abwechselnd eingefärbt werden. .table { border-collapse:collapse; border:1px solid #000; margin:10px; } .tableHeader { text-align:center; background-color:#B5B5B5; border-bottom:1px solid #000; padding:2px; } .tableRowOdd { text-align:center; background:#FFF; } .tableRowEven { text-align:center; background-color:#D3D3D3; } Des Weiteren setzen wir der Tabelle ein generelles inneres Padding damit die Zahlen und vorallem die Schaltflächen nicht so dicht an den Linien anliegen. tblContent.size()) { currentRows = 0; } return SUCCESS; } public String zurueck() { currentRows -= maxTblRows; if (currentRows = maxTblRows; } public boolean isDisplayWeiterBtn() { return displayWeiterBtn; } public void setDisplayWeiterBtn(boolean displayWeiterBtn) { this.displayWeiterBtn = displayWeiterBtn; } public boolean isDisplayZurueckBtn() { return displayZurueckBtn; } public void setDisplayZurueckBtn(boolean displayZurueckBtn) { this.displayZurueckBtn = displayZurueckBtn; } Diese Methode müssen wir bei jedem aufrufen der Schaltflächen ausführen. Somit haben wir die beiden Schaltflächen implementiert und können nun den ersten Test starten. Auswahlliste implementieren Als nächsten Schritt wollen wir nun eine Auswahlliste implementieren welche die Möglichkeit bietet eine bestimmte Seite anzusteuern. Zunächst einmal benötigen wir eine Liste für die Seiten. Und eine Logik welche diese Liste befüllt. Zuerst haben wir eine Liste mit den Werten für die Tabelle erzeugt diese benötigen wir um die Liste mit den Seitenzahlen zu erzeugen. Hier müssen wir die Anzahl der Einträge durch die maximale Anzahl der Tabelle dividieren und dieses auf die nächst höhere ganze Zahl aufrunden. private List pages = new ArrayList(); public String doRefresh() { ... pages.clear(); int maxPages = (int) Math.ceil((double) (tblContent.size() / maxTblRows)); for (int i = 1; i Read the full article

Learn Java from Basic to Advanced

Java becomes one of the most popular programming languages with several reasons. This programming language has many advantages, such as can run in different operating system, Object Oriented Programming (OOP), and has complete library that will greatly facilitate programmers, so it's very powerful. And today is the era where Android smartphones are very widely used. Applications in the Android smartphone are built using the Java language.

Java is open source technology. It means you can see the source code, and develop and custom it according to your own purpose. Java is used to develop various types of applications, from console application, desktop application, enterprise-scale application, to mobile application. To fulfill the different applications needs, Java categorized into three editions:

Java SE (Standard Edition) - to develop desktop application and client-server application.

Java EE (Enterprise Edition) - to develop multi-tier enterprise-scale application.

Java ME (Micro Edition) - to develop application that can be run on micro devices or mobile devices.

Anyone who wants to start to learn Java, must learn from Java SE. Java SE is basic and core of Java Programming. After mastering Java basic (Java SE), you can choose whether you want to continue to Java EE or Java ME. Usually, people who learn Java basic don't get any issue to learn it. But when entering Java EE, one big question will appear: What should I learn? Because unlike Microsoft platform, there are so many technologies called "framework" used to build Java EE based application.

All roads lead to Rome. Every framework has its own way and own style. Every framework has own its advantages and disadvantages, but they are in same goal: to build robust and powerful Java application. For advanced user, this is good. Because they can choose and use proper framework that suitable with their needs. But for new comer in Java, this can be confusing.

I've done a little research on the needs of Java programmers in the world. Actually, there are also some companies who are looking for beginner (basic) Java programmers. Usually they will provide specific training to the programmers to enhance their Java skills fit to the company's needs. But, most of company are looking for advanced Java programmer, specially Java EE programmer with qualification in several famous Java framework. The fact is, company pays higher for advanced Java Programmers.

The following are some of Java EE framework and other related technologies that are sought by many companies: JPA, Hibernate, iBATIS, JSF, PrimeFaces, RichFaces, XHTML, JSP, Servlet, AJAX, jQuery, EJB, Struts, Spring, JBoss, Tomcat, GlassFish, Weblogic, WebSphere, Web Services, Eclipse, NetBeans. That's not all. There are still many other Java EE frameworks. But don't worry, you don't have to mastering all. But like I said, a new comer in Java will be confused, which framework should I learn?

From the list of framework above, I already tried almost all of them. I've been worked in system development in several IT consultants and software houses. In reality, many application development works are system enhancement or customization. So you don't have any option to choose framework. But for creation new application, you have to create from scratch. It is good if company already have framework standardization. But if not, you have to choose which framework should be used.

Yes, You don't have to mastering all framework. And I think in the fact, none of people mastering all of Java framework. But, of course you want the company to pay you high, right? As the fundamental for you in obtaining a good job as a Java programmer, you must mastering several framework. Which one? I've been using various of Java EE framework. And I found the most powerful stack of frameworks (at least for me). This uses MVC (Model-View-Controller) design pattern. The stack of frameworks is:

Model: Hibernate

View: JSF + RichFaces

Controller: Spring

With this stack of frameworks, you can do rapid application development. It's also not too difficult to learn it compared to other frameworks.

For summary, this blog will teach all techniques of programming in Java SE, which is the core of Java programming. You will be invited to get to know, understand, practice, and able to implement the concepts required in basic Java programming. The Java SE material in this blog will start from the simplest, the mastery of basic elements of program such as: architecture in Java program, Java program creation, compilation technique, data type, operator, control structure, and so on. You also will be invited to know what Object Oriented Programming is and how is its implementation in Java.

After mastering Java SE, This blog will take you to enter Java EE, start from its concept, and also its implementation using stack of frameworks I mentioned above. To make you fully understanding of Java EE implementation, this blog will give sample of application development: how to create Employee Management application from scratch using the stack of frameworks.

This blog is dedicated to anyone who is interested in learning Java programming. All material in this blog are presented in tutorial dialect and immediately accompanied by examples of programs that will be easy to understand. To make you easier to learn all the material presented, within this blog you can download all resources (such as installer, library, etc.) that are needed. The final goal of this blog is to guide, lead, and deliver you to become a high valuable Java programmer.[Source]-https://javabasictoadvanced.blogspot.com/p/preface.html

We provide the best Advanced Java training, navi mumbai. We have industry experienced trainers and provide hands on practice. Basic to advanced modules are covered in training sessions.
