Response is already committed!!! HELP!!!! NEWBIE
Hi, i've a problem that don't know how to fix.
A "java.lang.IllegalStateException: Response is already committed!" exception
is beeing thrown when i set the content type to ms-excel in the
pagebeginrender method of a page:
// This is the code i'm using to set the content type on the pageBeginRender
HttpServletResponse responses =
this.getPage().getRequestCycle().getRequestContext().getResponse();
try {
responses.setContentType("application/vnd.ms-excel");
responses.setHeader("Content-disposition",
"inline; filename=report.xls");
responses.setContentType("application/vnd.ms-excel");
responses.flushBuffer();
} catch (IOException e) {
e.printStackTrace();
}
and this is the full stacktrace:
java.lang.IllegalStateException: Response is already committed! at
com.evermind[Oracle Application Server Containers for J2EE 10g

This is getting sewwious. (sorry, if you have kids you'll know ;))
pageBeginRender() is a method that means rendering content back to the
browser has already started, at which point it is too late to set the
content type of your response.
You might try a listener method approach instead, or use a hivemind service
to do it directly.
