HttpServletRequest.getRequestDispatcher fails on filter

Question

Hi,
I am a newbie to oc4j. I am trying to integrate urlrewritefilter (j2ee implementation of mod_rewrite from tuckey) and struts2 in my application to run on oc4j (*10.1.3.4.0*). This way I can rewrite legacy urls to struts2 action classes.
urlrewritefilter is not able to get a request dispatcher to struts2 actions. I was able to get dispatcher for a test servlet but not to the struts2 filter. It works perfectly on tomcat 6.0
According to [http://download.oracle.com/docs/cd/B32110_01/web.1013/b28959/filters.htm#BCFGCJID] it should be working.
This call to request dispatcher works only if the path is to a servlet but not a filter.
HttpServletRequest.getRequestDispatcher("/doc/MyAction.action") -- does not work on oc4j but works on Tomcat 6.0
HttpServletRequest.getRequestDispatcher("/TestServlet") -- works on oc4j and Tomcat 6.0
Following is the concise version of the configuration that I am using
<web-app id="starter" version="2.4"
xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee [http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd]">

<url-pattern>/doc/*</url-pattern>
<dispatcher>FORWARD</dispatcher>
<dispatcher>REQUEST</dispatcher>
</filter-mapping>
<servlet>
<servlet-name>TestServlet</servlet-name>
<servlet-class>mypackage.TestServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>TestServlet</servlet-name>
<url-pattern>/TestServlet</url-pattern>
</servlet-mapping>
</web-app>
Is there any more configuration that needs to be set? I also tired setting "-Doracle.j2ee.filter.on.dispatch=true" on opmn.xml
Thanks for the help.
