Http proxy servlet using struts

Question

Hi,
I have 2 web application "webApp1" which based on struts, and "webApp2".
I'm trying to http proxy a servlet from "webApp2" to "webApp1" and to redirect the call to an action in "webApp1"
that's what I wrote in "webApp2"/web.xml, I expect it to arrive GetAction.do in "webApp1":
<servlet>
<servlet-name>GetHttp</servlet-name>
<servlet-class> weblogic.servlet.proxy.HttpProxyServlet </servlet-class>
<load-on-startup>1</load-on-startup>
<init-param>
<param-name>redirectURL</param-name>
<param-value> http://localhost:7001/GetAction.do </param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>GetHttp</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
but I fail on NullPointerException, any idea what's missing???
Thanks all...
