well this code is not mine.  i got it from the site http://xml.apache.org/
hope his works.
   these are the steps that i used for tomcat

1.put the FopServlet.class in
  tomcat/webapps/examples/web-inf/classes/org/apache/fop/tools/servlet

2.add the following to the web.xml in the conf directory of the tomcat
   <servlet>
	<servlet-name>
            Fop
        </servlet-name>
	<servlet-class>
            org.apache.fop.tools.servlet.FopServlet
        </servlet-class>
   </servlet>

3.put the fo file in the tomcat/fop/example directory

4.add fop.jar and w3c.jar to the lib directory of tomcat

5.call the fo file throught the browser


http://servername/servlet/FopServlet?fo=/fullpath_to_tomcat/fop/example/read
me.fo
and u will get readme.pdf displayed.


u can do according to ur web server.  i dont think that step 2 is requred if
it is not tomcat.
all the best.
do tell me if it works.
cheers!!!
