jsp include/RequestDispatcher incompatible?
have the following code in my jsp, which is called by a forward from my
Controller servlet. The various Dispatchers are either servlets or jsps declared
in my web.xml.
All the servlets and jsps get run correctly. The problem is the output. The
output of the root jsp and the 3-4 included jsps are arbitrarily rearranged, see
below. Bizarre shuffling, not reverse order, but a different order and not
interleaved with the text from the jsp.
If I translate the jsp into servlet code, and use RequestDispatchers
for all the components,
the page works. The documentation says something about flushing buffers, but I
can't see how to do this with RequestDispatchers.
Code:
<BODY>
<jsp:include page="WEB-INF/jsps/portal/header.jsp" flush="true"/>
<% if(option1) {
application.getNamedDispatcher("Option1Servlet").include(request,response);
} else { %>
<table><tr>
<% if(option2) { %>
<td><%
application.getNamedDispatcher("Option2Servlet").include(request,response);
%></td>
<% } %>
<td><%
application.getNamedDispatcher(page).include(request,response); %></td>
<td><%
application.getNamedDispatcher("InfoServlet").include(request,response);
%></td>
</tr></table>
<% } %>
</BODY>
generated html:
<BODY>
Page text // from the page dispatcher
Info servlet text // from the infoservlet dispatcher
Header form text // from the header.jsp dispatcher
<table><tr>
<td></td>
<td></td>
</tr></table>
</BODY>

Feh. Easier to just translate the whole jsp into a servlet by hand
which is what I already did.

Try flush first, otherwise you might need to pass a
HttpServletResponseWrapper() to include() where the wrapper oversrides
getOutputStream() (or getWriter()

Re: jsp include/RequestDispatcher incompatible?

So before each request dispatcher call I need to call a flush on the
out in the JspPage? How do I get access to it?
Do I also need to call flush at the end of each request dispatcher call?

The out from the jspwriter is NOT the same out as receieved by
response.getWriter();
The out in the JspPage is buffered.
