writing to response stream from action

trying to call an action in a jsp page to return some html on http response stream, but it doesn't seem to like it. i am using the itext library's html writer.

i have an action-mapping where /ledger.do maps to Ledger.class which is an action.
in ledger.jsp:
<jsp:include page="/ledger.do" />

in Ledger.java:
ServletOutputStream out = response.getOutputStream();
response.setContentType("text/html");
HtmlWriter.getInstance(document, out);

the problem is that the http headers have already been sent so...
is there any way to write html back to the response stream?
I don't mind changing class type to httpservlet.

Use getWriter, not getOutputStream and you won't have a problem.
(the jsp's implicit out variable is a wrapper (indirectly) for response.getWriter - and you cannot call both getWriter and getOutputStream without throwing an exception (according to the specs))

Think I misinterpreted your question.

Have you tried increasing the buffer in the jsp page (thereby giving your action and itext more chance of altering the headers before they are written)

I think you will need to write a servlet, not a Struts action to do this task...

ideally i would like to output to the http stream without headers, to allow the html to be embedded into the page

fixed

used ByteArrayOutputStream to store the output of itext htmlwriter, then usedbaos.toString() to pump into response.getWriter().
