IllegalStateException: Cannot forward. Response already committed.
Thanks in advance for any help on this...
I understand we get this exception when the JSP attempts to write to the print stream after the response has been committed but I don't see how this is occurring in my situation since my JSP just contains a simple forward.
Index.jsp
<%@ taglib uri="http://struts.apache.org/tags-logic" prefix="logic"%>
<%@ page contentType="text/html" import="org.apache.log4j.Logger"%>
<%
final Logger log = Logger.getLogger("index.jsp");
log.debug("begin");
%>
<logic:forward name="welcome" />
Here is my action class (note that in my logs, this exception occurs even before the execute method is called!):
public class ChoiceAction extends StrutsAction {
public ActionForward execute(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception {
log4j.debug("execute");
ManifestChoiceFormBean choiceForm = (ManifestChoiceFormBean) form;
Connection conn = DAOUtils.getConnection("jdbc/OSURptDb");
try {
RenderRequest req = (RenderRequest)request.getAttribute("javax.portlet.request");
String sites = getResources(request).getMessage("upsws.site.list." + req.getPreferences().getValue("SITE_IND","").toLowerCase());
log4j.debug(sites);
IMailManifestDAO dao = DAOBuilder.buildMailManifestDAO(conn);
boolean uspsActive = dao.uspsJobsExist(sites);
choiceForm.setUspsActive(uspsActive);
log4j.info("USPS link is " + ((uspsActive) ? " active": " not active"));
return mapping.findForward("next");
} finally {
DAOUtils.closeConnection(conn);
}
}
static final Logger log4j = Logger.getLogger(ChoiceAction.class);
}

Try turning the page buffer up really high... Like 256k or something
obnoxious. It's obviously not a real solution, but it might get you by if
you're on a deadline. I would try firing up a debugger and see what is
generating the output. Another solution would be to try a different app
server. If you're running in Tomcat, try Jetty to see if that helps you narrow
down the issue.

RE: IllegalStateException: Cannot forward. Response already

Posted by Hermann X Lau <he...@jpmchase.com>.
Hi,
I tried out your suggestions and I am still getting this exception. I even put everything in the JSP in one line and mad sure there were no whitespaces.
<%@ taglib uri="http://struts.apache.org/tags-logic" prefix="logic"%><%@ page contentType="text/html" import="org.apache.log4j.Logger"%><%final Logger log = Logger.getLogger("index.jsp");log.debug("begin");%><logic:forward name="welcome" />
Any other ideas?

Subject: Re: IllegalStateException: Cannot forward. Response already committed.
The JSP compiler simple turns those <% %> tags inside out and
everything outside of those tags is a string with an out.print... In
your case, the first two things in the file generate returns...
Whitespace is significant... Let me see if I can make it visually more
understandable
Index.jsp
<%@ taglib uri="http://struts.apache.org/tags-logic" prefix="logic"%>
<---- RIGHT HERE, You will get a out.print("\n");
<%@ page contentType="text/html" import="org.apache.log4j.Logger"%>
<----- SAME HERE
<%
Hopefully it doesn't get all wrapped and screwed up.
You might be wondering now, why does it work sometimes and not
others... Well, the IllegalStateException is only thrown if output has
been flushed, so you can get away with breaking the rules from time to
time. You can even set the page buffer variable really high so that
you reserve the right to redirect, even if you have generated some
output.
Anyhow, try to remove whitespace, you could probably just do it this
way and have it work -
Index.jsp ->
<%@ taglib uri="http://struts.apache.org/tags-logic" prefix="logic" %><%@
page contentType="text/html" import="org.apache.log4j.Logger"

Re: IllegalStateException: Cannot forward. Response already committed.
Posted by Dale Newfield <da...@newfield.org>.
Sorry to hijack this thread, but it looks like Wes has already given you
a pretty complete answer.
At first I thought you were going to be asking about this:
http://wiki.glassfish.java.net/Wiki.jsp?page=FaqWebAppUnableToSetRequestCharEncoding
I get a warning in my glassfish logs for pretty much every request, and
while I've not spent time to track this down I was hoping someone else
here might have figured this one out already.
I see that in the prepare method of
org.apache.struts2.dispatcher.Dispatcher it calls setCharacterEncoding
on the request, so that does seem pretty early in the process...
...so either that's not getting called or something else is also trying
to set this later and that's the source of my problems?
