How can we bind a error message with a UI component (e.g. a Text box) ? I don't want the error message to be a global one. For achieving error message in the same in Struts 1: In the form validate method, I used this: ActionErrors errors = new ActionErrors(); if(userName != null && userName.length() <= 0) errors.add("userName",new ActionError("error.userName.required")); and in the UI, for displaying the message: In Struts 2, If I extend the Action class with ActionSupport and use this: addActionError(getText("Please enter UserId")); Then it seems to be a global message which can be displayed in the UI using: Hence not sure how to achieve the same functionality in Struts 2.

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 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 144823 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"
