JSF - Add Data to DataTable
Advertisements
In this article, we'll showcase adding a row to 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 sub-chapter of JSF - Data Tables chapter. |
| 2 | Modify home.xhtml as explained below. Keep rest of the files unchanged. |
| 3 | Compile and run the application to make sure business logic is working as per the requirements. |
| 4 | Finally, build the application in the form of war file and deploy it in Apache Tomcat Webserver. |
| 5 | Launch your web application using appropriate URL as explained below in the last step. |
home.xhtml
<?xml version="1.0" encoding="UTF-8"?>

<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">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>
<h3>Add Employee</h3>
<hr/>
<table>
<tr>
<td>Name :</td>
<td><h:inputText size="10" value="#{userData.name}" /></td>
</tr>
<tr>
<td>Department :</td>
<td><h:inputText size="20" value="#{userData.dept}" /></td>
</tr>
<tr>
<td>Age :</td>
<td><h:inputText size="5" value="#{userData.age}" /></td>
</tr>
<tr>
<td>Salary :</td>
<td><h:inputText size="5" value="#{userData.salary}" /></td>
</tr>
<tr>
<td> </td>
<td><h:commandButton value="Add Employee"
action="#{userData.addEmployee}" /></td>
</tr>
</table>
</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 following result:
Add values to Add Employee Form and click Add Employee button.See the result.
