An Introduction To JBoss RichFaces
Application
Creating a new project
- Select File/New/JSF Project
- For the project name, enter “richfaces-start”
- For JSF environment, select JSF 1.2, Facelets, RichFaces
- For a template, select one based on the Tomcat version you are using
- Click Finish to create the project
Creating the model class
As we are dealing with users, we are going to create a user model class.
In the JavaSource directory, create an example.model.User Java class and notice the package name:
package example.model;
public class User {
@Override
public String toString() {
return name + " " + email;
}
private String name;
private String email;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public User(String name, String email) {
super();
this.name = name;
this.email = email;
}
}
The class is very simple. Our application will list one or more of these users. Next, we are going to create a managed bean. The managed bean will basically be a model for the user interface we will be building shortly.
Creating the managed bean
In JavaSource, create an example.beans.UserBean Java class. Again, pay attention to the package name:
package example.beans;
import java.util.ArrayList;
import java.util.List;
import javax.annotation.PostConstruct;
import example.model.User;
public class UserBean {
private List <User>users;
public List <User>getUsers() {
return users;
}
@PostConstruct
public void init () {
users = new ArrayList <User>();
users.add (new User("Joe", "joe@gmail.com"));
users.add (new User("Charley", "charley@ymail.com"));
users.add (new User("John", "john@hotmail.com"));
users.add (new User("Greg", "greg@gmail.com"));
users.add (new User("Prescila", "prescila@aol.com"));
}
}
This class is also simple. A list of five users is created and place inside an ArrayList. The @PostConstruct annotation is useful for initializing properties. It guarantees that the annotated method will only be called once when the bean is created.
To make this bean a managed bean, we need to register it in a JSF configuration file.
- Open WebContent/WEB-INF/face-config.xml
- Switch to the Tree view
- Select Managed Beans and click Add...
- Keep the scope request
- For Class, enter the bean’s full Java class name, example.beans.UserBean
- For Name, enter or keep userBean - Click Finish
We are ready to create the user interface.
Managed bean registration looks
like this:
<managed-bean>
<managed-bean-name>userBean</managed-bean-name>
<managed-bean-class>example.beans.UserBean</managed-bean-class>
<managed-bean-scope>request</managed-bean-scope>
</managed-bean>

Hi,
I'm using this code on a seam project and it work properly, but, it doesn't work when the table datatable is sorted. I don't know how to get the row id after user has sorted the table. Now I use the position inside the List of elements I pass to the datatable.
thanks in advance

Can I use "keepAlive bean" for the <rich:tree/> component? For example:
<a4j:keepAlive name="someForm"/>
<rich:tree value="#{someForm.data}">

Thanks a lot. The "keepAlive bean" or bean with page scope should implement the java.io.Serializable interface and because of that I asked about "keepAlive bean" and rich:tree component. I see that org.richfaces.model.TreeNode implements java.io.Serializable interface.
Now, my example with rich:tree is good except I can't know when a node is collapsed. I use this example http://stackoverflow.com/questions/1509962/is-there-an-event-for-collapsing-a-richtree-node
but state.isExpanded(key) is always true!

Is there an out of the box solution to filter tree objects, just like <rich:dtatTable>? if there is none, how would you go about implementing this fuctionality. I'm trying to implement help page.
thanks
