Welcome Back. When i started learning ZK, one of the challenge thing for me to dynamically generate the Menu from the Database using different components of ZK. We managed using via MVC and created all the stuff using pure java. But now thanks to MVVM and Children binding mechanism of ZK. Using that, with minimal lines of code, we can achieve the result.
This post will talk about creating Dynamic Menu using different ZK Components
Part 1: This article will explain how we can use ZK Menu Component to build N level of menu dynamically
Part 2: This article will explain how to create Tree type Menu dynamically.
Part 3: This article will explain how to create Left Navigation Menu Using group Box and Tool Bar Button
Part 4: This article will explain how to create top level navigation menu with two levels dynamically.
Part 5: This article will explain how to create 4 Level of Menu for an Web app application
You can see the online demo here and download the source code.

In Part 3, we have seen how to create left navigation menu using ZK Group Box and ZK Tool bar button dynamically and also in part 4, Using the same data set, We created two level menu in the top using Tab box and Tool bar as like this ZK Demo.
Now we will combine Part 3 and Part 4, i.e we will create 4 level menu, 1st level in Tabbox , 2nd Second Tab Panel Tool Bar Button, 3nd Level Left Group Box and 4th Level Tool Bar Button under each group Box.

In most of the application, Menu are build up from the database and maintain user level screen access to control access. Now let us see how we can create dynamic menu using different ZK Components. In this part, we will see how we can use ZK Menu component to build up.
Assume that, our application menu has the following structure(Just for an example)
1.Administration
Secuirty
Accounts
User
Role
User Rights
Role Rights
Regional
Clock
Language
Keyboard
Devices
Printer
Projector
Mouse
Network
Wireless
Connection 1
Connection 2
Adapter
Local Area Connection
Virtual Box Network
Internet Optons
General
Programs
Content
Privacy
My Computer
Drives
C Drive
D Drive
E Drive
Favorites
Desktop
Downloads
Recent Places
Google Drive
2. ZK
Products
ZK SpreadSheet
3D Cell
Freeze rows
Ranged Cells
ZK Pivottable
Drill Down
Render
Paging
ZK Calender
Views
Drag and Drop
Time Zones
ZK Spring
HTTP Request
HTTP Basic
MD4 Password
Web Flow
ZK Demo
Grid
Master Detail
Data Binding
Dynamic Data
Data Filter
ListBox
Dual ListBox
Paging
Auto Sort
List Group

You can see, we have 4 Level Menu Structure
Let us start our coding part.

First let us setup the development environment. Download this document and follow the step by step instruction to install the necessary software’s.
Step 1:
Let us create new ZK Maven Project as shown in the following steps
In the Eclipse IDE, select File –> New-> Other->Maven Project
That’s all. Now you run and click on the ShowReport button to show the report as shown
Step 1:
Let us create new ZK Maven Project as shown in the following steps
In the Eclipse IDE, select File –> New-> Other->Maven Project
Click Next and Select zk-archetype-webapp 6.5.2 as shown below
Click Next and enter ireportExamples for Group ID, Artifact ID and package as shown. Select 6.5.2 version and click Finish
New Maven Project will be created with the following folder structure
Step 2:
Define a Person.java POJO class as defined below. This is the Java bean data source that is going to provide the data to the report.
package ireportExamples;
public class Person {
private String firstName;
private String lastName;
private Integer age;
public Person(String firstName, String lastName, Integer age) {
this.firstName = firstName;
this.lastName = lastName;
this.age = age;
}
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
public Integer getAge() {
return age;
}
public void setAge(Integer age) {
this.age = age;
}
}
We need the .class for the above java file. Just compile and run the project by right click on the project name and Select Run as –> Run on Server
Step 3:
Next we will start with iReport. Goto http://sourceforge.net/projects/ireport/files/?source=navbar and download iReport 5.1.0 windows installer exe as shown
After download, install the ireport and Run. After the welcome screen, Select File –> New as shown
Select Blank A4 and Click on Open this Template
Enter the Report Name and Location as shown above.
Now Let us add Report Title.On the Palette window, look for Label Static Text and select that and drag to title band in the designer.
Now double click on the Static text and change the text as My First Report as shown
Now Let us change the font size. Click on Window -> Properties to change the font size as shown
Very Important Note, Select the myFirstReport in the left navigator and Right Click and Select Properties
Select Language option to “Java”
Add the column header for the report by dragging and dropping the "Static Text" for the column headers.
Next, we need to Tell iReport where to find the classes by defining the class path via Tools --> Option, and then select the "Classpath" tab.
Next let us define the Report query. Click Report query icon as shown
Goto JavaBean Datasource and type ireportExamples.Person in the class name and Click Read attributes button as shown
Select firstname, lastname and age as shown
Now Come to detail section and Drag a Text Field from the Palette
Right Click and Select Edit Expression
Remove the default expression and double click on firstname
Click Apply. Repeat the same steps for Lastname and age
Now save the report and Right click on myFirstReport on the Left navigation and select Complie report
And after successful compile, iReport will create jasper file in the path we specified earlier. The file name will be
Step 4:
Now let us come back to java application. First let us add the jasper report dependency in our POM File. Open the POM File and add the following
<dependency>
<groupId>net.sf.jasperreports</groupId>
<artifactId>jasperreports</artifactId>
<version>5.1.0</version>
</dependency>
Next create a folder called reports under webapp folder as shown
Copy the myfirstreport.jasper file in the above folder as shown
Modify the index.zul file as follows
<zk>
<window apply="org.zkoss.bind.BindComposer"
viewModel="@id('vm')@init('ireportExamples.MyViewModel')">
<button label="Show Report" onClick="@command('showReport')" />
</window>
</zk>
Modify the MyViewModel.java as follows
package ireportExamples;
import java.util.ArrayList;
import java.util.List;
import net.sf.jasperreports.engine.JREmptyDataSource;
import net.sf.jasperreports.engine.JRException;
import net.sf.jasperreports.engine.JasperFillManager;
import net.sf.jasperreports.engine.JasperPrint;
import net.sf.jasperreports.engine.data.JRBeanCollectionDataSource;
import net.sf.jasperreports.view.JasperViewer;
import org.zkoss.bind.annotation.Command;
import org.zkoss.bind.annotation.Init;
import org.zkoss.zk.ui.Executions;
public class MyViewModel {
private List<Person> personDataSet = new ArrayList<Person>();
@Init
public void init() {
fillpersonData();
}
@Command
public void showReport() throws JRException {
String reportFile = Executions.getCurrent().getDesktop().getWebApp()
.getRealPath("/reports");
reportFile = reportFile + "/myfirstreport.jasper";
JasperPrint jasperPrint = JasperFillManager.fillReport(reportFile,
null, new JRBeanCollectionDataSource(personDataSet));
//view the report using JasperViewer
JasperViewer.viewReport(jasperPrint,false);
}
private void fillpersonData() {
personDataSet.add(new Person("John", "Smith", 25));
personDataSet.add(new Person("David", "Thomas", 15));
