Today we will look into two tags that are related to action class response that error message we can use in the result pages.Struts 2 Action Error and Action Messageactionerror tag: This tag is used in conjunction with Action class validation for form fields. If validation fails for any form fields, we can add action errors and then Struts 2 API forwards the request to "input" result struts2 error message page where we can use this tag to show the error messages. This tag is helpful in server side validation of form fields and then returning the input page with error message. Syntax of this tag is: error handling Struts Validation and error handling Struts provides capabilities to validate form properties in two major modes, one is Java and the other is XML related. Another feature of Struts is error handling. In this tutorial we want to explain both of them and show you a small example application using these features. General Author: Sascha Wolski Sebastian Hennebrueder Date Updated: December 2007 First edition: February 2005 Software: Struts Framework 1.3 PDF download: http://www.laliluna.de/download/struts-validation-error-handling-en.pdf Source download: http://www.laliluna.de/download/struts-validation-error-handling.zip Requirements We require the basics of Struts to understand this tutorial. If you are new to Struts, read the ‘first steps in struts' tutorial, you can find at http://www.laliluna.de/articles/posts/first-steps-using-struts-tutorial.html. Create a struts project Let's start, create a new struts project and a package named de.laliluna.tutorial.validation. Action form class (java related validation) Create a new class ExampleForm in the package de.laliluna.tutorial.validation.form, which extends the class ActionForm. 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).
