how to use html:errors

[Sevika]

Hi,
I am new in Struts. I want to display error message in view. For that, in my bean (ActionForm) I have written validate() method :-

ActionErrors validate(ActionMapping mapping, HttpServletRequest request)
{
ActionErrors errors = null;
if( name.equals("") )
{
errors = new ActionErrors();
errors.add("error_username", new ActionError("error.name.required"));
}
return errors;
}

In view I have wriitten "html:errors".
But it is not displaying me anything what else I have to do to show error messages.Can u tell me.

thanks.

you will need to have something along the lines of -

<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>

at the top of you page otherwise the "html" tag will be meaningless!

hi A Harry,
That I have alredy included. Something else that I have to do. Do I have to mention something in struts-config.xml file.

thanks

Hi,

Ya u need to specify in struts-config.xml as validate=true while declaring action tag. And be sure that error.name.Required is in ApplicationResources.properties. And place that properties file under WEB-INF\classes. Check it works.
