JSF - Add Data to DataTable

In this section, 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 - DataTables chapter.
2	Modify home.xhtml as explained below. Keep the rest of the files unchanged.
3	Compile and run the application to make sure the 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.

      <h:form>
         <h:dataTable value = "#{userData.employees}" var = "employee"

               #{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 the following result.

Add values to Add Employee Form and click Add Employee button. See the following result.
