Hey,
That was one of my thoughts as well, as I do keep those references,
but only to make it easy when passing on, and I do this inside a
synchronization block on the "keeper" object, at the end of which
(inside a finally) I release them.
Eitherway, here is some more proof that it is tomcat:
I am receiving the following error in my logs: Response already
committed in Search.replyBody()
Let me show you how this can happen (I verified by 'n grep that this
is the only place in the code this error occurs).
Firstly, this is my doGet():
public void doGet(HttpServletRequest req, HttpServletResponse resp)
throws ServletException
{
tmpl = new JSPTemplate("/templates/search.jsp", req, resp);
// long curMillis = System.currentTimeMillis();
String service = WebClient.getString(req, "service", null);
if (service != null)
{
service = service.toLowerCase();
if (service.equals("srchfrm"))
{
replySearchForm(req, resp);
}
else if (service.equals("log"))
{
}
else if (service.equals("listeditions"))
{
replyJS(req, resp, Edition.getWebEditionList());
}
else if (service.equals("showindexes"))
{
replyHtml(req, resp, Edition.showIndexes());
}
}
else
{
String itemPath = req.getRequestURI();
if (itemPath != null)
{
int i = itemPath.lastIndexOf('/');
if (i != -1) itemPath = itemPath.substring(i + 1);
i = itemPath.indexOf('?');
if (i != -1) itemPath = itemPath.substring(1, i);
// System.out.println(itemPath);
replyBody(req, resp); // do the search
}
}
}
Then replyBody's first few looks like this:
private void replyBody(HttpServletRequest req, HttpServletResponse resp)
{
WebClient theClient = null;
try
{
if (resp.isCommitted())
{
System.err.println("Response already committed in Search.replyBody()");
resp.sendError(HttpServletResponse.SC_INTERNAL_SERVER_ERROR,
"Please contact the webmaster with this error code:
Search.replyBody()");
}
As you can see I am receiving a fresh response object, and checking it
for "committedness", which it evaluates to true.
Inside the tomcat code, is a fresh response object created for every
request? Or are they shared?
