Add two properties, name of type String and age of type String. Add a getter and setter method for each property. Initialize the properties in the reset() method. The following source code shows the content of the class ExampleForm. public class ExampleForm extends ActionForm { private String name; private Integer age; public String getName() { return name; } public void setName(String name) { this.name = name; } public Integer getAge() { return age; } public void setAge(Integer age) { this.age = age; } } The Validate Method The action form class provides a method validate() which is called before the action class is executed. So you can validate your properties within this method. The return-value of the method is a collection (ActionErrors) of error messages (ActionMessage).
You can validate your properties and add error messages to this collection for each wrong validation. In the JSP file you can display these messages to the user. The error messages are message keys of the message resource bundle.
