JSF Checkbox Options from Managed Bean





Hey guys in this post, we will discuss reading the checkbox options from Managed Bean with Example.

Overview


  • To create a checkbox we use <h:selectManyCheckbox> tag
  • <h:selectManyCheckbox> takes value property which will hold the value of the selected checkbox option
  • We will use  <c:selectItems> tag to add the checkbox option from managed bean
  • <c:selectItems> takes the property value, which will contains the checkbox options in List, Set etc.,
  • <ui:repeat> is used to loop through the array. It takes value property, which contains the array and takes var property, which contains the single item, when each time loop runs.

Create a bean


Create Register.java inside the in.bushansirgur.jsf.beans package and add the following content

package in.bushansirgur.jsf.beans;

import java.util.Arrays;
import java.util.List;

import javax.faces.bean.ManagedBean;

@ManagedBean
public class Register {
	
	private String email;
	
	private String password;
	
	private String role;
	
	private List roleOptions;
	
	private String active;
	
	private List statusOptions;
	
	private String[] permissions; 
	
	private List permissionOptions;
	
	public Register() {
		this.roleOptions = Arrays.asList("User", "Admin", "Power Admin");
		this.statusOptions = Arrays.asList("Active", "Inactive");
		this.permissionOptions = Arrays.asList("Create", "Read", "Update", "Delete", "All");
	}

	public String getEmail() {
		return email;
	}

	public void setEmail(String email) {
		this.email = email;
	}

	public String getPassword() {
		return password;
	}

	public void setPassword(String password) {
		this.password = password;
	}

	public String getRole() {
		return role;
	}

	public void setRole(String role) {
		this.role = role;
	}

	public List getRoleOptions() {
		return roleOptions;
	}

	public void setRoleOptions(List roleOptions) {
		this.roleOptions = roleOptions;
	}

	public String getActive() {
		return active;
	}

	public void setActive(String active) {
		this.active = active;
	}

	public List getStatusOptions() {
		return statusOptions;
	}

	public void setStatusOptions(List statusOptions) {
		this.statusOptions = statusOptions;
	}

	public String[] getPermissions() {
		return permissions;
	}

	public void setPermissions(String[] permissions) {
		this.permissions = permissions;
	}

	public List getPermissionOptions() {
		return permissionOptions;
	}

	public void setPermissionOptions(List permissionOptions) {
		this.permissionOptions = permissionOptions;
	}
}

Create Input form


Create register-form.xhtml file inside the WebContent and add the following content

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"
		xmlns:h="http://xmlns.jcp.org/jsf/html"
		xmlns:c="http://xmlns.jcp.org/jsf/core">

	<h:head>
		<title>Input Form</title>
	</h:head>
	
	<h:body>
		
		<h:form>
			
			Email: <h:inputText id="email" value="#{register.email}" />
			<br/><br/>
			Password: <h:inputSecret id="password" value="#{register.password}" />
			<br/><br/>
			Role: 
			<h:selectOneMenu value="#{register.role}">
				<c:selectItems value="#{register.roleOptions}"/>
			</h:selectOneMenu>
			<br/><br/>
			Status:
			<h:selectOneRadio value="#{register.active}">
				<c:selectItems value="#{register.statusOptions}" />
			</h:selectOneRadio>
			<br/><br/>
			Permissions:
			<h:selectManyCheckbox value="#{register.permissions}">
				<c:selectItems value="#{register.permissionOptions}" />
			</h:selectManyCheckbox>
			<br/><br/>
			<h:commandButton value="Register" action="dashboard" />
		</h:form>
		
	</h:body>

</html>

Create a response page


Create dashboard.xhtml page inside the WebContent folder and add the following content

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"
		xmlns:h="http://xmlns.jcp.org/jsf/html"
		xmlns:ui="http://xmlns.jcp.org/jsf/facelets">

	<h:head>
		<title>Dashboard</title>
	</h:head>
	
	<h:body>
		
		<div>
			<span>The Logged in user is: #{register.email}</span>
			<span style="float: right;">Role: #{register.role}</span>
		</div>
		<div>
			<p>Your profile is: #{register.active}</p>
		</div>
		<div>
			<p>You have the following permissions:</p>
			<ul>
				<ui:repeat var="permission" value="#{register.permissions}">
					<li>#{permission}</li>
				</ui:repeat>
			</ul>
		</div>
	</h:body>

</html>

At the top we will add the schema xmlns:ui="http://xmlns.jcp.org/jsf/facelets for iterating the items.
