I would like to know if someone knows an errors management tutorial in Struts. I'm looking specially for a tutorial (or example) of the tag, which I think would solve my problem. java jsp struts struts-validation share|improve this http://stackoverflow.com/questions/937584/htmlerrors-struts-tutorial-or-example question edited Apr 8 '11 at 2:09 Bill the Lizard 222k139447737 asked Jun 2 '09 at 1:34 Tere 1251213 add a comment| 2 Answers 2 active oldest votes up vote 8 down vote accepted Here's a quick summary. You have an ActionForm class, say MyForm: You have an Action class, say MyAction: "name" in the action refers to "name" in the form-bean. Because you have validate="true" your ActionForm class MyForm must define validate() method which will automatically be called: public ActionErrors validate(ActionMapping mapping, HttpServletRequest request) { ActionErrors errors = new ActionErrors(); if ((username==null) || (username.length() < 1)) errors.add("username", new ActionError("error.username.required")); return errors; } If it returns an empty ActionErrors object, Struts goes on to call your MyAction.execute(). Otherwise, Struts displays /insert.jsp (because that's the input= parm you gave) and expands the html.errors tag to display your errors from ActionErrors. share|improve this answer edited May 31 at 12:13 Tom11 1,27041029 answered Jun 4 '09 at 16:40 Mark Lutton 3,63632842 Thank you!

The tags in the Struts HTML library form error in a bridge between a JSP view and the other components of a Web application. Since a dynamic Web application often depends on gathering data from a user, input forms play an important role in the Struts framework. Consequently, the majority of the HTML tags involve HTML forms. Syntax to use Struts HTML tag library error in struts <%@ taglib prefix="html" uri="http://struts.apache.org/tags-html" %> < html:errors > < html:errors > -Displays a set of error messages prepared by a business logic component and stored as an ActionMessages object, an ActionErrors object, a String, or a String array in any scope. If such a bean is not found, nothing will be rendered. This tag displays the messages which are set in the Validate method of the ActioForm. ActionErrors object should be created to hold the error messages.String is passed to the constructor of ActionErrors object. The String is a key from the ApplicationResources.properties file.< html:errors/> Tag will extract the information from ActionErrors object and displays the errors. Example Code for < html:errors > Login Application is created with Struts HTML tags and Struts ActionForm which illustrates both the < html:errors/> tag and < html:password/> tag 1.Create an Jsp page and name it as login.jsp.It is the Welcome page for a user. login.jsp <[emailprotected] contentType="text/html" pageEncoding="UTF-8"%> <[emailprotected] prefix="html" uri="http://jakarta.apache.org/struts/tags-html" %> <[emailprote
