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? -----Original Message----- From: Wes Wannemacher [mailto:w...@wantii.com] Sent: Wednesday, May 20, 2009 4:48 PM To: Struts Users Mailing List 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" %><% final Logger log = Logger.getLogger("index.jsp"); log.debug("begin"); %><logic:forward name="welcome" /> On Wed, May 20, 2009 at 4:39 PM, Hermann X Lau <hermann.x....@jpmchase.com> wrote: > 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) ?
