ok! Then Cactus is the right tool .. :-)

I don't understand the question ? From the JSP spec :
"
JSP.9.2.1.8 Constructors
public PageContext ()
JSP.9.2.1.9 Methods
[...]
public abstract void forward (java.lang.String relativeUrlPath)
This method is used to re-direct, or "forward" the current ServletRequest
and
ServletResponse to another active component in the application.
If the relativeUrlPath begins with a "/" then the URL specified is
calculated
relative to the DOCROOT of the ServletContext for this JSP. If the path
does not begin with a "/" then the URL specified is calculated relative to
the
URL of the request that was mapped to the calling JSP.
It is only valid to call this method from a Thread executing within a _jsp-
Service(...)method of a JSP.
Once this method has been called successfully, it is illegal for the calling
Thread to attempt to modify the ServletResponse object. Any such
attempt to do so, shall result in undefined behavior. Typically, callers
immedi-ately
return from _jspService(...)after calling this method.
Parameters:
relativeUrlPath - specifies the relative URL path to the target resource as
described above
"
Note that you can also use pageContext.include() if you wish.
