If validation fails for any form fields, we can add action errors and then Struts 2 API forwards the http://www.journaldev.com/2274/struts-2-action-error-action-message request to "input" result 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:We will look it's usage with a simple project to explain how easy s:actionerror is to use.actionmessage tag: This tag is used to show some custom message added by Action classes in the result page. For example, we can use this tag to welcome a user and show them last login time at the top of the page. Syntax of this tag is:Both these tags generated an unordered list of action errors or messages added in the action class. Let's create a simple project to show their usage.

Let's say user clicks 2nd anchor button link, approriate div having html form loads in.. There I have a file upload browse button, using interceptor below, restricting upload limit maxsize and content type: 15728640 application/pdf Then in java class extending ActionSupport, getting return type as display error message input if in case of violation of maxsize and content type. SO In struts.xml I defined page.jsp But this causes page.jsp to reload, not maintaining the same html div state, i.e 2nd form of div tag,which again one has to go and click on 2nd anchor tag button, thus loading file browse form. Rather than Keeping inside of file browse form of second div tag, I can keep it at start of a body tag to display returned error message. But I want user inputs like 'file browse path' to stay in the input fields, and error messages shows above the fields. If I can convince myself to display error messages on another jsp page, there wouldn't be so much trouble. But just to speculate, is it possible to achieve what I desired? struts2 validation interceptor share|improve this question asked Jul 26 '12 at 11:41 Ashish Kataria 144822 add a comment| 1 Answer 1 active oldest votes up vote 0 down vote You can put this code wherever you want to show the errors Also, if you want to show corresponding div which containes the form to show up on page load you can use the same strategy in your javascript code script document.getElementById("div2").display="block";//or trigger click on the corresponding link

In my Struts 2 app, I have an interceptor class that is meant to validate my error fields. It has this method to add action errors ... private void addActionError(ActionInvocation invocation, String message) { Object action = invocation.getAction(); if(action instanceof ValidationAware) { ((ValidationAware) action).addActionError(message); } } How do I display these on my JSP? On my target JSP, I have this Struts 1 code (which is obviously invalid in Struts 2):
