JSF - Using DataModel in a DataTable
In this section, we'll showcase the use of datamodel in a dataTable.
Example Application
Let us create a test JSF application to test the above functionality.
Step | Description |
---|---|
1 | Create a project with a name helloworld under a package com.tutorialspoint.test as explained in the JSF - Display DataTable subchapter of JSF - DataTables chapter. |
2 | Modify UserData.java as explained below. |
3 | Modify home.xhtml as explained below. Keep the rest of the files unchanged. |
4 | Compile and run the application to make sure the business logic is working as per the requirements. |
5 | Finally, build the application in the form of war file and deploy it in Apache Tomcat Webserver. |
6 | Launch your web application using appropriate URL as explained below in the last step. |
UserData.java
package com.tutorialspoint.test; import java.io.Serializable; import javax.faces.bean.ManagedBean; import javax.faces.bean.SessionScoped; import javax.faces.model.ArrayDataModel; import javax.faces.model.DataModel; @ManagedBean(name = "userData", eager = true) @SessionScoped public class UserData implements Serializable { private static final long serialVersionUID = 1L; private static final Employee[] employees = new Employee[] { new Employee("John", "Marketing", 30,2000.00), new Employee("Robert", "Marketing", 35,3000.00), new Employee("Mark", "Sales", 25,2500.00), new Employee("Chris", "Marketing", 33,2500.00), new Employee("Peter", "Customer Care", 20,1500.00) }; private DataModel<Employee> employeeDataModel = new ArrayDataModel<Employee>(employees); public DataModel<Employee> getEmployees() { return employeeDataModel; } }
home.xhtml
<?xml version = "1.0" encoding = "UTF-8"?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns = "http://www.w3.org/1999/xhtml" xmlns:h = "http://java.sun.com/jsf/html" xmlns:f = "http://java.sun.com/jsf/core"> <h:head> <title>JSF tutorial</title> <h:outputStylesheet library = "css" name = "styles.css" /> </h:head> <h:body> <h2>DataTable Example</h2> <h:form> <h:dataTable value = "#{userData.employees}" var = "employee" styleClass = "employeeTable" headerClass = "employeeTableHeader" rowClasses = "employeeTableOddRow,employeeTableEvenRow"> <h:column> <f:facet name = "header">Sr. No</f:facet> #{userData.employees.rowIndex + 1} </h:column> <h:column> <f:facet name = "header">Name</f:facet> #{employee.name} </h:column> <h:column> <f:facet name = "header">Department</f:facet> #{employee.department} </h:column> <h:column> <f:facet name = "header">Age</f:facet> #{employee.age} </h:column> <h:column> <f:facet name = "header">Salary</f:facet> #{employee.salary} </h:column> </h:dataTable> </h:form> </h:body> </html>
Once you are ready with all the changes done, let us compile and run the application as we did in JSF - First Application chapter. If everything is fine with your application, this will produce the following result.
