Installing RichFaces

Installing RichFaces is very easy.

Download
Download the latest RichFaces version from http://www.jboss.org/jbossrichfaces/ .

Add three RichFaces JAR files to your application WEB-INF/lib directory:

  • richfaces-api-X.X.X.jar,
  • richfaces-impl-X.X.X.jar,
  • richfaces-ui-X.X.X.jar


RichFaces also depends on the following libraries: commons-beanutils.jar, commons-collections.jar, commons-digester.jar, commons-logging.jar

As of the writing of this article, the latest RichFaces version is 3.3.0 .

Note: to use Hibernate Validation, additional JAR files are needed. The JAR files are included in the project. 


RichFaces Filter
Register the RichFaces filter in a web.xml file:

<filter>
<display-name>Ajax4jsf Filter</display-name>
<filter-name>richfaces</filter-name>
<filter-class>org.ajax4jsf.Filter</filter-class>
</filter>
<filter-mapping>
<filter-name>richfaces</filter-name>
<servlet-name>Faces Servlet</servlet-name>
<dispatcher>REQUEST</dispatcher>
<dispatcher>FORWARD</dispatcher>
<dispatcher>INCLUDE</dispatcher>
</filter-mapping>

 Skinning

Optionally, to use one of the existing skins, add the following:

<context-param>
<param-name>org.richfaces.SKIN</param-name>
<param-value>laguna</param-value>
</context-param>



Note: new skins such as laguna, glassX and darkX are available in their own separate JAR files.

Page Setup

If you are using Facelets, then add this to your page:

xmlns:a4j="http://richfaces.org/a4j"
xmlns:rich="http://richfaces.org/rich"


Just in case you are still stuck with JSPs, you would then add this to your pages:

<%@ taglib uri="http://richfaces.org/a4j" prefix="a4j"%>
<%@ taglib uri="http://richfaces.org/rich" prefix="rich"%>


A little bit further in this article, I have created a ready-to-use Eclipse project with RichFaces and Spring already configured. We are going to import the project into Eclipse and then start development. In the “real” world, you would probably use Maven 2, but, to keep things simple and concentrate on RichFaces and Spring, we are going to use a ready-made project.

Spring

Not to repeat what has been said about Spring in numerous great articles and other resources, I will not list every Spring feature. You can find numerous resources on the Internet.  Simply stated, Spring is a framework that greatly simplifies enterprise Java development.

The part that's of interest to us here is Spring beans and injection of control (there's a great article on it here ). Spring is often a great candidate for a middle tier in a Web application. While JSF offers us managed beans and basic dependency injection, Spring's dependency injection is much more powerful. Why use two containers (JSF and Spring) to manage beans when you can use just one?

As I mentioned at the beginning, I will show you two ways to configure Spring beans. One is XML-based and the other is annotation-based. Even the XML-based configuration significantly reduces the amount of XML you have to write compared to the XML configuration of JSF managed beans.

What exactly are you thinking by posting an 11 MB zip file that contains nothing but library jar files? Are you getting some perverse pleasure by wasting other people's time and bandwidth? Do you know the meaning of the word courtesy? Apparently not.

If you don't want to post your code don't post a zip. It's as simple as that.

Hi Max, Great work!..

i have a problem, i have added the validation conditions in managed bean of the JSF page

ie :

@NotEmpty(message = "Country Name must not be empty.")

@Pattern(regex = ".*[^\\s].*", message = "Spaces are not allowed.")

private String countryName;

 

i have several  <a4j:commandButton> and <a4j:commandLink> in the same page, validation fires each and every time i press a commandLink or Button,   iif that field is empty("countryName" as i specified here)

how can i control the validation to fire for the particular button or a link...?  (i need validation to be fired when only i clicked the save button)

please help me on this...

Thx Max, It helped me to solve my problem,

I have another question,

I want to generate dynamic checkboxes depends on a collection, so i have written

<h:dataTable id="functionsGrid" value="# {functionManagedBean.collecOfFunctions}"                                                            var="function"  >
                                                                                   
<h:column>
      <h:selectBooleanCheckbox id="#{function.functionName}" value="#{functionManagedBean.checked}"/>
 
    <h:outputLabel for="" value="outputLabel"></h:outputLabel>

</h:column>                            
                                                                                   
</h:dataTable>



and finally this form contains an <a4j:commandButton> , in the managedBean side i want to get the selected checkboxes....(problem is checkboxes are generating dyamically, so how can assign their values for the different properties in the managedBean..

Thank you very much in advance.. :)

I have problem where the Next button could't go to next page . I am not using Facelets .But i use jsf . I have configure my faces-config.xml file properly .What is the possible root cause ? Can you share your working example ? email to me . monsiong@yahoo.com . Thanks

I encountered the same problem, but only after switching to Spring Annotations and Component Scan. The reason is rather simple: the WizardBean now no longer receives the value for the startPage (which was set to "/page1.xhtml" in the spring application context before) and now the renderer ends up in a endless loop.

So if you want to use the annotation based version, manually set the parameter in the bean.

Please email me the correct file. I am not able to open or download the source code. The one file from which I downloaded contained only jars and no significant java files or any other code. PLease email me as early as possible at 2008Shariq@gmail.com

Hi, For the NotSerializableException, I tried to implement Serializable but didn’t work and I had a Spring Exception : my backing bean has a bean injected through spring. The solution was to look for the bean through getBean(“beanName”) rather than injecting it.

Fabio Malheiro replied on Tue, 2010/09/28 - 8:26am

This was supposed to be a good tutorial right?

I was trying to implement your example... but I'm a little bit confused. Sometimes you "talk" about a bean orderService, and Service ... but where the fuck is the Service class?

Andres Botero replied on Wed, 2010/11/17 - 12:02pm

When i inyect a dependency into a bean it's null. For Example:

<bean id="wizardBean" class="bar.view.WizardBean" scope="request">
   <property name="orderService" >
    <ref bean="service" />
   </property>
</bean>

In that case the orderService is null, colud you tell me why is that?

After Migrating from XML configuration to Annotation based configurated i am getting the following error.

at com.sun.facelets.el.VariableMapperWrapper.resolveVariable(VariableMapperWrapper.java:60)

the error trace is too long thats why i am pasting it here.

I create the spring3 template project with STS and follow your instruction.

Its working well for xml configuration.But getting error when i am going to annotation based configuration

I came across this example and ran across a few problems and wanted to post the solutions once the project is imported. The project is using Tomcat 6.0 but I was using Tomcat 7.0. There were about 3 places in the project preferences I had to change from Tomcat 6.0 to Tomcat 7.0. Here were 3 of the places. Just look through the preferences. 1. preferences -> Java -> Compiler 2. preferences -> Server -> Runtime Environment 3. preferences -> Java Build Path Because I was using jdk 1.7.0, I had to update the facets on the project at: preferences -> Project Facets and change the Java to 1.7

Thanks for posting.

Hi! Nice article. This is what I'm looking for but in an upgraded version. I wonder if you tried it with RichFaces4 and Spring3.0. Would it be as seamless as here? Andika
