Image problem on tomcat

Hello all,
I have an image problem on the Tomcat server.
I have a picture with a special Korean format: cwsis. It is just like
any other jpg or gif image, but with a format that is not popular.
The image itself is on the tomcat server.
I am trying to display the image on a special mobile browser, by
requesting it from a jsp on the tomcat server,
But the browser can not display it.
When I am trying to display it from another apache server it works ok.
The code is as follows:

<jsp:useBean id="entryB" class="com.pele.mmbox.beans.AlbumEntryBean"
scope="session"/>
<pre>
</pre>
<img src="http://10.171.193.85:8090/mmbox/o549d000212946200.cwsis">
<a href="testDownload.jsp">down</a>

Any ideas?
TIA Yuval
