Subject: Replace logic:messagesPresent with JSTL tags



Hi,

I'm using the the  tag to print out validation error 
messages. Now I want to replace the Struts logic tags with JSTL tags. 
Hence I wrote:



 
   
 
   
 
   
 
   
 


But error messages are not shown even if there is definitely an request 
attribute with the name org.apache.struts.action.ERROR.
And even more strange for me is the fact that it works if i use scriptlets 
and do it this way:


<% if (request.getAttribute("org.apache.struts.action.ERROR") != null) {%>
 
   
 
   
 
   
 
   
 
<%}%>

Thanks in advance for any hints to solve this little problem.

Regards
Franz

Hi John,

> I think you should be able to use:


${!empty requestScope['org.apache.struts.action.ERROR']} 


as your test, since requestScope is a Map object.


Thank you. That's what I forgot: The escaping because of the periods in 
the request attribute name.

Well, normally for a request attribute I'd just use
${requestScope.attributeName}, but you can't do this here since there
are periods in the attribute name.  I think you should be able to use:

${!empty requestScope['org.apache.struts.action.ERROR']} 

as your test, since requestScope is a Map object.
