Error deploying Web Service after upgrading from WL 7.0 No Service Pack to SP5

Question

Hello
I have problem using HttpServletResposneWrapper with a ServletFilter in WLW
7.0 SP5. When I apply the filter to JWS file in Development Mode, following
Exception is thrown when I access a JWS.

===================================================================
I have looked at "weblogic.knex.dispatcher.HttpRequest" class. It seems like
this class tries to cast the response object to "ServletResponseImpl" class,
so ClassCastException is thrown.
Is there any workaround for this issue, since my code is compliance with
J2EE standard. Thank you very much in advanced.
