Re: Exception report - HTTP Status 500 -
If you installed your Tomcat using the Debian package manager, take a look at the tomcat startup script. While it's been a number of years since I used Debian, I seem to remember this from back in the day - look for a statement referencing "security" or "use security" or something to that effect and comment it out. Restart Tomcat and see if that doesn't fix it.

Jeffrey is having a bear of a time getting APR working in his environment due to a number of issues that are all piling up. My advice: set up a testing environment where you can play and perform load testing. Compare the performance of the NIO versus APR connectors. - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkvI0V0ACgkQ9CaO5/Lv0PB1awCbBSPmpnyo1zPSn0pEmXwBBTVm 1kkAoJtNgbJHSRBCEbQpjhiFhg6ucAS1 =U+zf -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

The keyword here is welcome page. If your WAR file does not have

According to the web.xml that you posted, your application will

/FileUploadServlet/servlet
As Homer Simpson would say: "D'oh!". I was clicking on the application

i.e. it was trying to go to http://localhost:8080/FileUploadServlet. As
soon as I added "/form" to the URL it came up fine! It has been at least
four or five years since I last played with a servlet so I simply forgot

Tomcat Shutdown suddenly / random
Hi folks, we are facing a serious problem with our tomcat which shuts itself down after some time of running. this problem first arises after we switched to our new server. we are using tomcat 6.0.26 (also tried different other 5.5.x, 6.0.x versions). the "old" server was a 32 bit red hat enterprise linux system. the new server is a 64 bit debian 5 (also tried debian 6). the log always gives us the following message, so as if the tomcat has been cleanly shutdown, which is really strange. 16.04.2010 11:52:42 org.apache.coyote.http11.Http11Protocol pause INFO: Pausing Coyote HTTP/1.1 on http-8080 16.04.2010 11:52:43 org.apache.catalina.core.StandardService stop INFO: Stopping service Catalina 16.04.2010 11:52:43 org.apache.coyote.http11.Http11Protocol destroy INFO: Stopping Coyote HTTP/1.1 on http-8080 we also tried to switch the shutdown-message and the shutdown-port, without effect. the tomcat process is started with a non-root-user. the server runs for 15 minutes to 8 hours before it happens. any suggestions or help would be nice. cya, peter - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
Re: question about APR based native library
Sorry about my assumption(s). I made them based on information I gathered from talking to Tomcat users I know. My sample size is small so my assumptions may not be valid. By smaller user community I don't mean APR. I mean the APR connector Http11AprProtocol.

I had this instance and another one on the same machine both hit the max last night and the acceptor stopped waiting on workers. All the workers show their normal wait state, and some of the Pollers showed they were waiting on workers also. What I appear to be seeing is that the requests come in and get processed on a minimal number of workers, but at some point, new workers are getting created until we reach the maxThreads limit (150). I'm not seeing a traffic load that indicates that it should ever be using that many workers, there are only about 15-20 end users in the app at any one time. I'm not seeing this on other systems running the same version of the app & tomcat, although they are running a much older native library. I've been monitoring the instance using jconsole. On the instance that died early last night, they were sitting at about 135 worker threads at 8:00am and stayed there all day, even with some cursory logging in and checking a few pages during the day. Then, at about 7:00pm, when the Asia user based started working, the Threads graph in jconsole starts climbing, levels for about 30 minutes, and then climbed the rest of the way until it hit the 150 limit. Almost as though it wasn't using the bulk of the existing worker threads. The resulting threads looked just like those in the previous thread dump -- all workers in normal wait state, but the Acceptor waiting on workers. Question: Could there be something that our programmers are doing (or more likely NOT doing) that would allow workers to return to waiting, but not actually be free for work? Otherwise, I'd have to assume something in the native library is mucking up the thread pool count.

I found out jboss uses a hybrid of Tomcats server.xml file and its own central way of setting ports for all its services. The file for central port settings in jboss 5.1.0.ga is /server/default/conf/bindingservice.beans/META-INF/bindings-jboss-beans.xml, but its faily obscure. Inside the bindings-jboss-beans.xml theres a piece of XSLT that transforms and overwrites the Connector tag from the server.xml file. The XSLT works from a base port and theres no direct mention of 8443 which is why I could find the config with "find . -exec grep 8443 ...". Some of the XSLT transformation wont match the connector tags in server.xml if the ports have been changed in server.xml and I found lots of posts from people trying that approach - all in all it looks like an extremely flaky way of controlling ports centrally but maybe its just because im doing it wrong. This is what worked for me: Change this line in bindings-jboss-beans.xml : To: (I believe this breaks the general jboss port settings based on having a single base port from which other ports are calculated) - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

The keyword here is welcome page. If your WAR file does not have
index.jsp or index.html, or some explicit mapping for its root
address, you will get a 404 response trying to access the root of your
webapp.
According to the web.xml that you posted, your application will
respond to the following URLs:
/FileUploadServlet/form
/FileUploadServlet/servlet
Some pointers:
http://tomcat.apache.org/tomcat-6.0-doc/index.html
http://tomcat.apache.org/tomcat-6.0-doc/appdev/index.html
http://wiki.eclipse.org/WTP_Tomcat_FAQ
You may also want to know, that ${catalina.base}/conf/web.xml provides
the defaults for your WEB-INF/web.xml.
Do not change that common file (in /conf), though, unless it is really needed.

Konstantin Kolinko

Re: mod_jk question about socket_timeout
On 16.04.2010 11:20, Philip Wigg wrote: Recent versions of mod_jk allow a very fine-grained response timeout configuration, so that you can e.g. set a general response timeout to 20 seconds and a longer timeout like 60 seconds for special URLs you expect to take longer like report generation. The cases where you would need short timeouts are the cping/cpong and during connection setup. For the latter there is now also a special timeout, so that you can actually drop the socket timeout. Have a look at: http://tomcat.apache.org/connectors-doc/generic_howto/timeouts.html which tries to describe the possible timepouts and their implications in great length. Thanks for your reply Rainer. I have had a read of that (very helpful) document but I guess what I was wondering was if socket_timeout would close a socket purely due to inactivity. The doc mentions timing out on 'operations', which I would take to mean establishing a connection or waiting for an ACK but actually it does seem to drop the connection purely because it's inactive. The exact behaviour of the socket_timeout is dependent on the platform and mod_jk version. It is not supposed to time out during wait for response, but I won't say it's 100% safe to rely on that.

The 6.0 would print a message if it can detect that there is no property with the given name in the class that this XML element configures. b) the file that you are changing is not the one that is actually used. I do not use JBoss, so there might be differences with what I know. E.g., you are saying about context.xml, but in Tomcat that is configured in server.xml. By the way, AFAIK, SSLEnabled="true" is not needed/not available in Tomcat 5.5, (no harm here, because unknown attribute will just be ignored, as I wrote above).

Re: Trouble accessing content in webapps/ROOT
HTTPD is serving them rather than Tomcat. Configure a separate document root for HTTPD and the we can fix your connector config. p On 15 Apr 2010, at 18:31, laredotornado wrote: > > What specifically is "wrong"?

Thanks for your reply Rainer. I have had a read of that (very helpful) document but I guess what I was wondering was if socket_timeout would close a socket purely due to inactivity. The doc mentions timing out on 'operations', which I would take to mean establishing a connection or waiting for an ACK but actually it does seem to drop the connection purely because it's inactive.

Re: Proposal : port mod_expires in java as ExpiresFilter Servlet Filter
Hello Christopher,
I imagine the project crew has been very busy these days. Do you
have feedbacks on the adaptations and explanations I did ? Is there
anything I could iterate on ?
To rephrase my previous email :
* I reduced the number of comparison against 'nulls' as you suggested.
I did this introducing a method
'isEligibleToExpirationHeaderGeneration(request)' with several
intermediate 'return' statements ; I found it easier to code than to
use nested if/else statements.
* The reason why I introduced the complexity of trapping the
'onStartWriteResponseBody' event is that I tried my best to implement
in ExpiresFilter the same behavior as in Apache Httpd mod_expires.

Re: Basic Question
For starting Tomcat in Eclipse, check this out: http://www.eclipsetotale.com/tomcatPlugin.html As for the other part, I'm not really sure at all. Good luck, though.
