Hello
We have been having trouble with the formatDate and formatNumber tags. I
have outlined in some detail an issue in the bug tracker (22892) but in
brief every time a format tag runs if no Locale is set it creates a default
Locale and then calls ServletResponse.setLocale(). Reading the JavaDoc for
ServletResponse.setLocale()
Sets the locale of the response, setting the headers (including the
Content-Type's charset) as appropriate. This method should be called before
a call to getWriter().
What happens on our large pages is that, running under OC4J, we get a
IllegalStateException response already committed error. Removing the
formatDate tag corrects the problem. the same occurs with formatNumber.
My main question is why is the code in
org.apache.taglibs.standard.tag.common.fmt.SetLocaleSupport
static void setResponseLocale(PageContext pc, Locale locale) {
// set response locale
ServletResponse response = pc.getResponse();
response.setLocale(locale);
// get response character encoding and store it in session attribute
if (pc.getSession() != null) {
pc.setAttribute(RequestEncodingSupport.REQUEST_CHAR_SET,
response.getCharacterEncoding(),
PageContext.SESSION_SCOPE);
}
}
written like it is? The Locale value gets set every time the tag runs so it
isn't being cached properly in any case. I am wondering if anybody else is
getting this type of error?
We have worked around the problem by commenting out the offending line. I
think the caching of the Locale needs to be looked at as the Locale is
always calculated as well.
