I have a problem with Apache, Tomcat
You can see from my logs that apache returns a 200 for my login page then
returns a 404 from
It seems to be an issue now and then. It works for a while then it tosses a
404. Maybe after a timeout I really dont know...Hard to recreate. but my
logs are full of 404 jsessionid issues...
Any help out there?

Re: I have a problem with Apache, Tomcat
Posted by nohacks <ph...@gmail.com>.
Thanks for all of your time on this problem.
I found the issue..!!!
It was a page caching issue with the browser. It seems the page was cached
and so not creating a new session for the Post button on Login.
I put the following in my login page and now it works great. The new session
is created.
<META Http-Equiv="Cache-Control" Content="no-cache">
<META Http-Equiv="Pragma" Content="no-cache">
<META Http-Equiv="Expires" Content="-1">
This forces the page to go back to server and get new session id. Because
old session id was expired.
I followed the logs from
Browser, Apache, ModJk, LB, Tomcat, App.
It all works for now. I might also use the Apache. CacheDisable Directive
http://httpd.apache.org/docs/2.2/mod/mod_cache.html#cachedisable
Thanks Again.

OK, and I assume you actually checked, that it *is* Tomcat that produces
the answer in the 404 case.
I forgot: Do you have the same problem, when using Tomcat directly via
the HTTP connector without Apache? If so, we should debug it without
Apache, because then it doesn't have to do with Apache.

The missing space after the "200" is due to a copy and paste error? It
is somewhat misleading, when the most important information in the line
(the status code) is corrupt.
Can you call the URL directly, without going through the login.jsf by
simply entering the long URL into the browser address line?
The next thing would be to redo the same request, but making sure, that
there is no session cookie send. So before sending the request and
before each of the following tests, clean up all cookies in your
browser. Especially that means do not go via the login page (which will
likely set the cookie), always use the troubling URL direct.
Do you also get a 200, when doing the same request without session cookie?
Then simply add a ";jsessionid=123" at the end of the URL, redo the test
(without cookie) to check what happens, if you use a session id for a
non-existing session.
If you can then reproduce the problem I would assume, that the 404 is
produced by the JSF component itself.

Rainer

I knew you'd say that, I was about to do the same.

Security, no. Load balancing, yes - if you can't afford a real one.

Re: I have a problem with Apache, Tomcat
Posted by nohacks <ph...@gmail.com>.
Hi Rainer,
Thanks very much for your responses. I have your answers below.
1) Which component should respond to this request, Apache or Tomcat?
Tomcat should answer all. I am not using Apache to server any Static
content.
2)Which part of your webapps is expected to serve the content for
Tomcat
/a4j_3_2_2-SNAPSHOTorg/richfaces/renderkit/html/css/basic_classes.xcss/DATB/eAF7sqpgb-jyGdIAFrMEaw__.jsf
We are using JSF and JBoss Richfaces.
or there is some servlet, which should answer that request dynamically
and is not configured right, resp. the servlet producing the page which
contains this link produces garbage in the page.
I dont think it is garbage, but you never know right. hahah.
I see it returns a 200 here..

1) Which component should respond to this request, Apache or Tomcat? I
assume Tomcat. Does the right component answer the request? If you don't
know, add an access log to Tomcat and check, whether the request hits
Tomcat or not.
2) Assuming yo want Tomcat to serve those and your configuration already
does that right. The URL doesn't really look like a usual static
content. Which part of your webapps is expected to serve the content for
/a4j_3_2_2-SNAPSHOTorg/richfaces/renderkit/html/css/basic_classes.xcss/DATB/eAF7sqpgb-jyGdIAFrMEaw__.jsf
If you can't answer that question, discuss with your developers. I
expect, that this does not refer to static content (a file with the name
eAF7sqpgb-jyGdIAFrMEaw__.jsf in a folder
.../richfaces/renderkit/html/css/basic_classes.xcss/DATB/). More likely
either this URL is totaly wrong and meant to address some static file like
/a4j_3_2_2-SNAPSHOTorg/richfaces/renderkit/html/css/basic_classes.xcss
or there is some servlet, which should answer that request dynamically
and is not configured right, resp. the servlet producing the page which
contains this link produces garbage in the page.

This really should work. Are you sure this configuration is being used?
Since you have /a4j_3_2_2-SNAPSHOTorg/* mounted, you shouldn't be
getting these errors:

Can you confirm that Tomcat never receives this request? Use the
AccessLogValve to get a logfile similar to the httpd one and observe
them in tandem.

Hi Guys,
Thanks for your feedback with this issue. This has been making me crazy for
such a long time.
I have put this in last night and tested.

JkMount /*.jsf loadbalancer
JkMount /* loadbalancer
JkMount /servlet/* loadbalancer
JkMount /a4j_3_2_2-SNAPSHOTorg/* loadbalancer

It does not work again. Strange it works for a while then when the session
times out there seems to be an issue.

Sometimes it's goog to convince yourself of something, rather than
accepting it as fact. That's always a good advice with statements made
on this list (and on the Internet in general). No offense taken.

It does not have to. The links are only a problem when the web server
attempts to service them. If the ";jsessionid=..." is stripped-away
before the files are located, then everything is okay.
> So the questions would be :

All URLs should be run through HttpServletResponse.encodeURL, which adds
the ";jsessionid=..." if the container isn't sure that the client
supports cookies. This allows sessions to be used even if cookies are
unavailable. It's also required by the Servlet Spec.

The OP never set *.css to be served by Tomcat. Had this been the case,
everything would have been okay, since Tomcat knows how to use the
";jsessionid=..." parameter (and also knows how to ignore it properly,
thank you very much httpd!).

FWIW that rule is this:
RewriteRule /contextPath/(.*);jsessionid=[0-9A-Z]*(.*)
/path/to/webapps/contextPath/$1$2 [L]
(I've been around this particular block several times. Bless Rainer and

No, it does not scan the content, but it does check requests and
manipulates them.
With JkStripSession On it will try to remove every ";jsessionid=..."
from the request URIs it does not forward to Tomcat, so that Apache
itself has a chance to find them. This is used e.g. when you put part of
your webap content to the fronting Apache and then use JkUnmount to let
Apache handle them. When you use URL encoded sessions instead of
Cookies, it could happen, that the encoding is also done for static
contenht, and JkStripSession will remove it.
In debug log it will log:
"no match for ... found",
"removing session identifier [...] for non servlet url [...]"

I didn't go through all of this discussion thread, but yes, f a 404 is
returned, one would first determine, whether it comes form Tomcat or
Apache (e.g. by activating Tomcat access log and checking whether the
request hits Tomcat or stays on Apache), then one would decide, whether
the system serving the request is actually the system one wants to serve
the request, and finally one would find out, why it returns 404.
Example 1: request served by Apache, but Tomcat should serve it: Check
mounting and unmounting rules
Example 2: request served by Apache as wanted, but unfortunately a 404
is returned: first send the request without the triling ;jsessionid=....
If this also returns a 404, the question is, how Apache is configured
and why it doesn't find the content. If this works and the request
including the ;jsessionid does not work, set JkStripSession On and
repeat the test. If it doesn't work, look at the mod_jk debug log for
the above logging lines and also at the Apache error log.

Re: I have a problem with Apache, Tomcat
Posted by André Warnier <aw...@ice-sa.com>.
Hi Chris too, and hi nohacks.
I was not quite convinced by Chris's explanation, so I tested this by
myself.
Apache httpd 2.2.3
mod_jk 1.2.18 (quite old)
Tomcat 5.5.27
In my case, URI's starting with /starweb are being redirected to Tomcat
by mod_jk (corresponding to the OP's case "/myapp").
I also set the JkLogLevel to "debug" for this test.
Then I accessed a URI that is re-directed to Tomcat, but fetches a
static html page there (that same page does not exist under Apache
httpd's DocumentRoot):
http://myhost/starweb/starlog4_example_static.html
That worked fine of course, delivered by Tomcat.
Then I added a dummy jsessionid to the URI, as follows :
http://myhost/starweb/starlog4_example_static.html;jsessionid=blabla
and tried again.
That also returned the page from Tomcat, no problem.
In the mod_jk logfile, I find this (edited, because there is at lot more
at the debug level) :
[Mon May 04 19:03:28 2009] [7189:47328] [debug]

[Mon May 04 19:03:28 2009] [7189:47328] [debug]
etc... (the rest shows the page being returned by Tomcat)
So, the above works, and at least for URI's supposed to be forwarded to
Tomcat, nor Apache httpd nor mod_jk are confused by the ";jessionid="
appendix to the URI.
It's also interesting to note that mod_jk, when it is called by Apache
to examine this URI and see if it wants to handle it, is smart enough to
first remove the "jsessionid=xxx" portion, before comparing the URI to
its list of things to forward.
Then I tried to access a document which is not redirected to Tomcat, but
located under Apache httpd's DocumentRoot :
http://myhost/starlog4.html
That worked also fine, and was delivered by Apache httpd.
Then I added a "jsessionid" attribute to this request :
http://myhost/starlog4.html;jsessionid=blabla
and then Apache httpd indeed returned a "404 Not found" error.
So, despite my initial scepticism (for which I apologise), Chris turns
out to be right.
The Apache error log shows :
[Mon May 04 19:21:16 2009] [error] [client 192.168.245.129] File does
not exist: /var/www/develop/starlog4.html;jsessionid=blabla
So indeed, the error is caused by (carefully, one item at a time) :
- the browser accesses the Tomcat application
- the Tomcat application returns a page (login.jsf), *in which* there is
a link to
/a4j_3_2_2-SNAPSHOTorg/richfaces/renderkit/html/css/basic_classes.xcss/DATB/eAF7sqpgb-jyGdIAFrMEaw__.jsf;jsessionid=7B8278D155437DE625509198918C08D4.tomcat2
- the browser thus issues a request to Apache to obtain this file
- somehow Apache + mod_jk do not thing that this URI should be forwarded
to Apache, so Apache tries to serve it itself
- and it does not find this object under its DocumentRoot and thus
returns a 404.
I don't think that mod_jk, even with the "JkStripSession" parameter on,
will scan each page returned by Tomcat, and /in the content/ change
these links to remove the ";jsessionid=..." part.
So the questions would be :
1) /why/ does the page returned by Tomcat contain the embedded <img>
tags with a "....;jsessionid=...." URI ?
What puts that jession-id there ?
OR
2) what makes it so that when Tomcat returns that page, Apache+mod_jk
think that this css URI does /not/ have to be forwarded to Tomcat ?
There must be, at the Apache level, a rogue JkUnMount or SetEnvIf no_jk
rule that interferes there, in the sense of not being quite smart enough
to know that this link /should/ be forwarded to Tomcat.
And if it should /not/ be forwarded to Tomcat after all, then you should
use a smart RewriteRule that will strip the ";jsessionid.." from these
URI's, before Apache attempts to find them locally.

I can tell you how to recreate it:
1. Log out of your application
2. Go to the login page
Result: your httpd logs are full of 404 errors for things like
mystylesheet.css;jsessionid=32456789 and
myloginimage.png;jsessionid=32456789.
The problem is that httpd thinks the ";jsesionid" is part of the path of
the resource, instead of a parameter. You can fix this either with
mod_rewrite (which is a bit heavy-handed) or you can use
JkStripSession On
if you are using a reasonably recent version of mod_jk.
Hope that helps,
