Hi, using the ReqestDispatcher.forward(URL) with a mapped URL I get the following repsonse: "...Mime mapping not found for file, while displaying static content..." I'm using IP WS/AS 6.0 AS SP2. Does anybody know what I have to do to let that work ? I'm trying to forward to a mapped URL like "logon.do" and want a specific servlet to be invoked described in my web.xml below. Invoking a mapped URL within the browser works, with the RequestDispatcher.forward() not ! Any help appreciated !! Oliver web.xml: ------------ <servlet-mapping> <servlet-name>ActionServlet</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping> <mime-mapping> <extension>do</extension> <mime-type>application/java-vm</mime-type> </mime-mapping>
