Error using servlet for external-graphic

[coospaa]

Hi all,

I'm trying to use a servlet to generate a dynamic image and am seeing the following error:

[ERROR] Error while creating area : No ImageReader for this type of image (

http://dappsn01.asianconnect.com/tnltptca/cmm/ImgServlet)

The relevant FO source is:

<fo:external-graphic start-indent="10pt" scaling="non-uniform" src="{/B3Report/url}/tnltptca/cmm/ImgServlet" width="180px" height="50px"/>

Does anybody know what might be causing this error?

thanks,
Coospaa
