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 https://www.mkyong.com/struts/struts-global-custom-exception-example/ 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. http://www.laliluna.com/articles/posts/struts-form-validation-error-handling.html 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. (You will find more infos about message resource bundle at http://www.laliluna.de/articles/posts/struts-message-resources-tutorial.html.)
