retrieve image from dynamic source and

[John C Cartwright <Jo...@noaa.gov>]

Hello All,

I'm trying to create a page using an HTML <img> tag that has as it's src 
attribute a URL.

my initial attempts were along the line of:

<img src="<c:url value="http://mapserver/servlet/com.esri.wms.Esrimap" 
var="url" >
       <c:param name="servicename" value="${param.servicename}"/>
    </c:url>">

however, the src attribute has the value of empty string in the 
resulting page.  Can someone point out what I'm doing wrong or suggest a 
better approach?

Thanks!

Take out the var="url", and the URL will be printed.  Right now the URL 
is being stored in that variable.  Alternateively, do the <c:url /> 
stuff first separate from the image tag, and then do <img src="<c:out 
value="${url}" />">
