Re[2]: How to use ???

[Dmitry Kashin <kd...@exch.inec.kharkov.com>]

Hello All

You are absolutely right, I can output messages this way and I already
use it, but now I want not output but check if error with specified
key present.
I found example at "Struts in action" chapter 12.
Thanks to authors!!!!!

It looks like this:
<logic:messagesPresent property="password2.notsame" >
     <tr bgcolor='red'>
</logic:messagesPresent>
<logic:messagesNotPresent property="password2.notsame">
     <tr>
</logic:messagesNotPresent>


NB> you can put the <html:errors> tag in your JSP page, this tag display the
NB> errors that are contained in the request parameter ERROR_KEY you can use it
NB> like this:
NB> in your java class ( action or form) do that:

NB> ActionErrors errors  = new ActionErrors();
NB> errors.add( "test", new ActionError(key))
NB> request.setAttribute(ERROR_KEY,errors);

NB> after this your error tag in the jsp page intercept the Error_key attribute
NB> and display it.

NB> Hope that help.
