What you describe is true only when you use the include directive
(i.e. <%@ include file="somefile" %>), not when you use the include
action (i.e. <jsp:include page="somepage" flush="true">).
When you use the include action, the JSP page of servlet specified
by the "page" attribute is executed and the response body is included.
The target JSP/servlet has access to all original parameters and you
can also add new parameters:
<jsp:include page="Test.jsp" flush="true">
<jsp:param name="username" value="eric"/>
<jsp:param name="editable" value="ok" />
</jsp:include>
The only mistake in the original mail in this thread is that the
syntax for the <jsp:include> action element is not correct. You
must not use the "/>" version of the tag when the element has a
body, as it has in this case.
In the target JSP/servlet, you access the parameters the same way
no matter if they are original or added, using getParameter() et al.
