Tomcat 7 Exception initializing page context; Cannot create a session
after the response has been committed
We are running Tomcat 7.0.26 (no httpd front end) with BIO/NIO and SSL
(entire webapp is in security context) and see this exception
periodically on our Linux server:
May 2, 2012 3:03:45 AM org.apache.jasper.runtime.JspFactoryImpl
internalGetPageContext

That line of code in our JSP's .java file show it to be method
_jspService's second statement:
pageContext = _jspxFactory.getPageContext(this, request, response,
null, true, 8192, true);
What might cause this? Curious as to why the 'service' method of
HttpServlet line 722 is called twice in the call stack. How could any
response have been sent out and committed when this seems to be before
my JSP's main body of code is even executed? After that line of code,
about 7 statements down is the code that emits the first HTML line from
our JSP:
out.write("<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.01//EN\"
\"http://www.w3.org/TR/html4/strict.dtd\">\r\n");
And right after that is where my page bean class is instantiated or
retrieved:
bean = (org.example.PlayerRegistration2Page)
_jspx_page_context.getAttribute("bean",
javax.servlet.jsp.PageContext.REQUEST_SCOPE);
if (bean == null){
bean = new org.example.PlayerRegistration2Page();
_jspx_page_context.setAttribute("bean", bean,
javax.servlet.jsp.PageContext.REQUEST_SCOPE);
}
My actual JSP source file top lines looks normal:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
<%@page contentType="text/html; charset=ISO-8859-1"
import="org.example.PlayerRegistration2Page"%>
<jsp:useBean id="bean" scope="request"
class="org.example.PlayerRegistration2Page" />
So this is Tomcat throwing an exception before it even reaches my code.
What might be the cause since of course the webapp works fine most of
the time.
Thanks,
David

This seems very Mojarra-specific. Since the OP didn't mention Mojarra,
why did you assume this was the same problem (and then not mention
that Mojarra was the problem)?
Your answer was confusing at best. Please post relevant followups.

As Chuck says earlier - this is, in almost all cases, a side-effect of
the application or framework incorrectly persisting a
request/response/session object in a Servlet instance field or some
other location that is not thread safe.

Producing enough data to cause a buffer-flush to the client, then
trying to create a session (and therefore a JSESSIONID cookie and
associated response header).

JspServlet is a servlet. Your JSP is compiled into a servlet. One
calls the other. Boom.

I too would have expected a forward() or include() in the call stack
somewhere, but something must be generating the content. Or, you have
a tiny tiny response buffer. Or your JSP is flushing the buffer
explicitly or something like that.

Unfortunately, this is going to require a bunch of research on your
part to find out what is happening. If you are buffering in a web
server (httpd) or something like that then you may be able to log
state on both sides when these errors occur: httpd can tell you how
many bytes were sent back (or maybe even capture the entire response
if it's small enough) and log it to a file, while your webapp will
obviously be able to catch the exception and log it however you wish.
I would start by catching that exception in a Filter and logging
everything you can about the request and response at that time. Then
wait for it to happen again and see what you can learn. Don't be shy
about dumping absolutely everything to the log when you see that
exception. Just be sure it's the right exception or you might end up
with way too much log output for other mundane exceptions.

Assuming he doesn't have a few KiB of whitespace surrounding the
<@page> directive, it shouldn't be a problem: the default response
buffer size is 8KiB.

As explained to the OP of this thread, in 99.9% of cases this is because
the application is improperly retaining a reference to a request or
session object.
Check your code for a Servlet or something that sets one of those two
objects to an instance field, or retains it in some other way that is
not thread-safe.

There are 2 exceptions at the same time. Why?
The exception is thrown out at
com.moza.qldtktts.util.CharsetFilter.doFilter(CharsetFilter.java:49). I
think about when CharsetFilter.doFilter get exception, i catch and check the
content of http request and response. What do you think about it?
Thanks

Re: Tomcat 7 Exception initializing page context; Cannot create a
session after the response has been committed
Posted by David Wall <d....@computer.org>.
Just a quick update on these several threads of Tomcat 7 oddball
exceptions. It looks to be as Chuck believed that it was a coding error
on our end that was causing this. In particular, it was the no-no
misuse of instance variables in a controlling servlet.
Thanks for everyone's help!
