JSF HTML Tags Reference (Exadel) This is a handy reference guide for the standard HTML tag library that is built into JSF. For these tags you need to use the following uri attribute for the JSP taglib directive at the top of the file: The table that follows shows you examples of HTML output and browser-rendered output for example uses of the tag library. Also, you can skip ahead to some instructions for downloading this reference as a Web application. Categories of JSF HTML Tags UIForm | UICommand | UIGraphic | UIInput | UIOutput | UIMessage and UIMessages | UISelectBoolean | UISelectMany | UISelectOne | UIPanel | UIColumn and UIData | UISelectItems | UISelectItem JSF HTML Tag Reference Running This Reference As an Application If you would like to run this reference as a Web application, download and deploy jsftags-guide.jar . Once you have downloaded the Jar file, only a few steps are required. jar -xvf jsftags-guide.jar Then add this context to Tomcat server:
PrimeFaces Lazy Loading DataTable for JSF2 « Nicholas Hrycan's Blog Summary This post discusses the benefits of paginating and lazy-loading large datasets that are displayed to users as well as the benefits of leveraging 3rd party JSF2 UI component suites. I’ve developed a simple application to demonstrate the concept which you can download and run. It is a maven2 project which uses PrimeFaces, Spring Framework, Hibernate/JPA2, and Ehcache. Background Often times your application must display a large data set to its users so they can operate on it. To make these large data sets manageable, pagination is often used. While a paginated data table component such as the one shown makes the data easier to manage, it is a non-trivial task to implement this type of component from scratch and make it reusable. Thanks to Java Server Faces (JSF), the Java community has access to a number of UI component suites to absolve the need to develop in-house UI components. The middle ground between these approaches is called Lazy Loading. Reviewing the method parameters
First Java Server Faces Tutorial (JSF) - Eclipse This tutorial facilitates the first steps with the quite new framework JavaServer Faces (JSF).

Introdução às Fases do Faces e FacesMessages - fabricio10 Vamos escrever um bean gerenciado com algum método de deva ser chamado a partir de um clique no botão. Primeiramente, vamos aprender a configurar os beans gerenciados nos próprios beans gerenciados, deixando de lado a chatice (ou parte dela) de configurar arquivos xml. Isto não tem absolutamente nada a ver com validação mas é um ponto interessante do JSF 2.0 que vale a pena aprender. Crie o bean gerenciado a seguir (escolha a opção de criar uma classe Java comum, e não um bean gerenciado): import javax.faces.application.FacesMessage; import javax.faces.bean.ManagedBean; import javax.faces.bean.RequestScoped; import javax.faces.context.FacesContext; @ManagedBean @RequestScoped public class ManterEntidadeBean { private String mensagem;public ManterEntidadeBean() {}public void inserir(){ setMensagem("Inserido!") }public String getMensagem() { return mensagem; }public void setMensagem(String mensagem) { this.mensagem = mensagem; OBS: NÃO escreva o trecho acima no faces-config. String msgIdade= “”;
Forum • View topic - DataTable lazy load filter doesn't work.. It works ... it works ... (and it is fast!) my sql schema has 26 tables. I summarize here only the "interesting" for this topic:The following is the italian administrative suddivision: (lower) (higher)Comuni->Provincie->Regioni->Aree (Translatable as municipality->province->region->area ?) all the tables have foreign keys: so an "area" has many "regioni" that has many "province" that has many "comuni". the xhtml code: /* * To change this template, choose Tools | Templates * and open the template in the editor package coqui.controller; import coqui.model.Comuni;import java.io.Serializable;import java.util.Iterator;import java.util.List;import java.util.Map;import javax.enterprise.context.SessionScoped;import javax.faces.bean.ManagedBean;import javax.faces.bean.ViewScoped;import javax.persistence.EntityManager;import javax.persistence.PersistenceContext;import javax.persistence.Query;import org.primefaces.model.LazyDataModel; private LazyDataModel<Comuni> lazyModel; private Comuni selectedComune;
Server-side Java: Understanding JavaServer Pages Model 2 architecture Despite its relatively recent introduction, JavaServer Pages (JSP) technology is well on its way to becoming the preeminent Java technology for building applications that serve dynamic Web content. Java developers love JSP for myriad reasons. Some like the fact that it brings the "write once, run anywhere" paradigm to interactive Web pages; others appreciate the fact that it is fairly simple to learn and lets them wield Java as a server-side scripting language. But most concur on one thing -- the biggest advantage of using JSP is that it helps effectively separate presentation from content. In this article, I provide an in-depth look at how you can gain optimal separation of presentation from content by using the JSP Model 2 architecture. So, what's wrong with servlets? While JSP may be great for serving up dynamic Web content and separating content from presentation, some may still wonder why servlets should be cast aside for JSP. htmlKona to the mix.

Debug JSF lifecycle Listen and debug JSF lifecycle phases The JSF lifecycle will be explained and debugged here using the "poor man's debugging" approach with sysout's. We'll also check what happens if you add immediate="true" to the UIInput and UICommand and what happens when a ConverterException and ValidatorException will be thrown. Well, you probably already know that the JSF lifecycle contains 6 phases: Restore view Apply request values Process validations Update model values Invoke application Render response You can use a PhaseListener to trace the phases of the JSF lifecycle and execute some processes where required. Note: if you don't have a JSF playground environment setup yet, then you may find this tutorial useful as well: JSF tutorial with Eclipse and Tomcat. Add the following lines to the faces-config.xml to activate the LifeCycleListener. <lifecycle><phase-listener>mypackage.LifeCycleListener</phase-listener></lifecycle> This produces like the following in the system output: Back to top 1. 2. 3. 4.
