Graphics does not render converting to PDF

[Ferad Zyulkyarov <feradz@gmail.com>]

Below is DocBook fragment that I want to render as a figure.
<figure>
     <title>The UML model to be compared</title>
     <mediaobject>
           <imageobject>
                 <imagedata fileref="figure1.eps" format="EPS"/>
           </imageobject>
     </mediaobject>
</figure>

The image I enclose (figure1.eps) deos not render neither with Apache
Cocoon nor with Jade. I just can not see the image from the most
popular PDF viewer such as Acrobat Reader, and the linux PDF viewers.

Thanks a lot for your help.
