sendRedirect throws illegalstateexception
Hey,guys,I know there are some question related to
illegalstateexception,however i've searched the forum for whole day and
still cann't solve the problem.
This is the description of my problem:
I added a phaselistener in web.xml to control user's visit of our web
site.The listener just implements this function:when user doesn't sign on
the site,it redirects user to the signon.jsf page.
Then we used code like this:
if (identity == null)
{
if (!request.getRequestURI().endsWith("EmployeeSignOn.jsf")
&& event.getPhaseId().equals(PhaseId.RENDER_RESPONSE))
{
org.apache.catalina.connector.ResponseFacade response =
(ResponseFacade)FacesContext.getCurrentInstance().getExternalContext()
.getResponse();
try
{
response.sendRedirect(DEFAULT_URL);
}catch( Exception e).....
in afterPhase function
However,it throws illegalStateException,I traced on ResponseFacade,it showed
the response is commited.
The code is simple,and i don't know when the response is commited,i havn't
called responseComplete yet.I think this may be caused by my confuzed
understand of the lifecycle.
Any one can give me some hint or other method to implement the requirement?
Thanks a lot.

Put breakpoints in the HttpServletResponse code or the sub class if someone
has wrapped the "real one" or build your own wrapper that uses "
System.out.println" in the addHeader/setHeader methods.
(there is no easy way besides debugging).
The other alternative is to remove all of your phase listeners and servlet
filters and if that fixes the problem, add them back 1 by 1 until the
problem occurs again.

we just use one phaselistener defined in faces-config.xml
<lifecycle>
<phase-listener>
base.presentation.common.ShowPhaseListener
</phase-listener>
</lifecycle>
and one extension filter(i think it won't effect the response,right?)
<filter>
<filter-name>extensionsFilter</filter-name>
<filter-class>org.apache.myfaces.component.html.util.ExtensionsFilter</filter-class>
</filter>
How can i know whether there is something wrote to the header before
redirection?
Thank you.

Do you have any filters or phase listeners that would be committing the
response? If any filters or phase listeners that run before your redirect
call set any HTTP headers or print any kind of output you will not be able
to redirect.

RENDER_RESPONSE,however, no matter whether i sendirect in phase RESTOR_VIEW
or RENDER_RESPONSE,it throws the exception.
when i redirect in RENDER_RESPONSE phase,it issues the exception and doesn't
rediret the page;
when i try to redirect in RESTORE_VIEW,the exception is still issued,however
the page is redirected to the signon.jsf.
Following is the stacktrace,hope them can give some hints:
23:11:28,390 INFO [STDOUT] java.lang.IllegalStateException
23:11:28,390 INFO [STDOUT] at
org.apache.catalina.connector.ResponseFacade.sendRedirect(ResponseFacade.java:423)
23:11:28,390 INFO [STDOUT] at
base.presentation.common.ShowPhaseListener.afterPhase(ShowPhaseListener.java:59)
23:11:28,390 INFO [STDOUT] at
org.apache.myfaces.lifecycle.PhaseListenerManager.informPhaseListenersAfter(PhaseListenerManager.java:89)
23:11:28,390 INFO [STDOUT] at

23:11:28,390 INFO [STDOUT] at

23:11:28,390 INFO [STDOUT] at

Thanks in advance!
