Hi Madan,
you can't use relative url in tc:image. Every string which is not
recognized as absolute url is used as resourceName to lookup in
resources.

Hi David,
As i am using Tobago, the URL i specify in <tc:image/> must be an absolute
URL instead of an relative url.
I tried with the code as below which resembles the same as the one u send
me.
<tc:image value="/downloadServlet?id=${content.contentImageId}"
height="100px" width="100px"/>
But the servlet is never called for this.
now i changed the value to an absolute url as shown below
height="100px" width="100px"/>
Now i am able to display the images.
But that should not be the case, i must not specify absolute url.
How to achieve this with relative url ?
Regards,
Madan

Subject: Re: [ Tobago ] Invoke Servlet from jsp page
Sorry, bad cut and paste of your code, it should be, of course,
<h:graphicImage id="image"
alt="image"
url="/DownloadBinaryServlet?id=#{groupBox.imageId}">
</h:graphicImage>
