<jsp:forward> plus the <jsp:include> are not working properly.

I have a jsp file named: "page1.jsp" and the user request to see this page.
in this jsp file after importing all the necessary classes, i include another page named "Header.jsp" like:
<jsp:include page="../Include/Header.jsp" flush="false" />

In this header file i connect to the database, and do some verification on whether the user can see page1.jsp file or not.
if he can see then no problem, if hedoesnt have the correct rightsto view the page then i forward the user to another page named "noAuthorization.jsp" like:
<jsp:forward page="../Administrator/noAuthorization.jsp" />

if i run this scenario using Tomcat then there is no problem, however if Oracle 9ias is used then what happens is that the noAuthorization.jsp file is displayed and then the page1.jsp file is also displayed.

In Tomcat what happens is that only noAuthorization.jsp file is displayed. This is what I want also, but somehow Oracle cant seem do do the trick.
Because of this I have some other errors too, which will be resolved after this is.

This is an urgent problem,
Thanks

You are using the wrong sort of include for what you are trying to achieve.
It's most likely that you really want to use:
<%@ include file="../Include/Header.jsp" %>

This is quite interesting for the <jsp:include> tag:
flush="true"
You must include flush="true", as it is not a default value. You cannot use a value of false. Use the flush attribute exactly as it is given here.

I don't know anything about Oracle 9ias. Could you please tell us which Servlet API it uses ?  
The reason I ask is because the limitation of JSP 1.1(Servlet 2.2 API). The page that searlas has pointed to in his post is descibing JSP 1.1.  
You didn't tell us which version of Tomcat you are using. But I would assume that it uses JSP 1.2 +.  The limitation was removed in JSP 1.2 and the value of the flush attribute  can now be true or false.   rrz
