Dariusz,

Someway, somehow, I get an error message
from struts or tomcat saying:
MAPPING configuration error for request URI

In my jsp i have:

<img src='/myImgServlet?imgId=<%= imgId %>'>

And my web.xml has the following mappings /
declarations:

<!-- Display Photo Servlet -->
 <servlet>
  <servlet-name>myImgServlet</servlet-name>
  <servlet-class>com.foobar.MyImgServlet</servlet-class>
 </servlet>

<!-- Display Photo Servlet Mapping -->
 <servlet-mapping>
      <servlet-name>myImgServlet</servlet-name>
      <url-pattern>/myImgServlet</url-pattern>
 </servlet-mapping>



Can someone help me out ?
