Re: Tomcat7-maven-plugin 2.0-beta1 and useSeparateTomcatClassloader fails with run goal
Hi Olivier,
It's actually the act of declaring a context.xml with a Loader element
that causes the application to fail. A new instance of WebAppLoader is
created, overriding the one carefully created by the plugin, without the
benefit of a properly configured class path. I've included a small patch
below which demonstrates my intent.
I'd added
classLoaderClassorg.springframework.instrument.classloading.tomcat.Tomcat
InstrumentableClassLoader/classLoaderClass to the plugin configuration,
which was then picked up correctly and used by the WebAppLoader.
Thanks,
Leigh

Dear all, A server that I manage has a Struts webapp with a Tomcat 5.5.x standalone server. No JMX or whatsoever has been configured. The app sends massive emails to users with some info that requires users to log on the webapp and fill in some forms. It seems (without any logs or metrics) that people tend to fill the forms right away after they got the emails and together with the mailing process (that requires DB use to get email addresses) is exhausting the maxthreads connections (300 as of yesterday which I have increased to 400). I assume it's not going to be easy to determine what is the cause of the issue but which tools can I use? I guess I need to log in some way how the server is behaving. Maybe enabling JMX or Javamelody? Any way of getting where the webapp is hanged or where in the code of the webapp is hanging?

Multipart over ajp btwn apache-tomcat fails sometimes...
Hi all, My stuff: Windows Server 2008 R2 64 bit Apache 2.2.22 with mod_proxy_ajp Tomcat 7.0.25 (On same server as Apache) I have an Apache acting as reverse proxy for a Tomcat over ajp. Apache conf for the proxyPass: Location /tomcatSite ProxyPass ajp://127.0.0.1:8009/tomcatSite ProxyPassReverse ajp://127.0.0.1:8009/tomcatSite /Location and the tomcat-config is really basic with nothing added to the default config. The webapp listening on /tomcatSite is a servlet-2.5 app and it works nicely for all types of request except when it comes to multi-part. We have a java-client uploading .zip-files every night to this webapp and sometimes it works and sometimes it fails. When testing we trigger the file upload manually using the same zip file every time with the same result: sometimes it works, and sometimes it fails. What happens when it works: Client sends multipart http-request to Apache. Apache proxy to Tomcat over AJP Servlet is called on doPost Servlet uses apache-commons-fileupload 1.2 to parse the request Servlet does something with the file Servlet returns (200 OK) What happens when it doesn't work: Client sends http-requst Apache proxy request Servlet is called on doPost Servlet uses apache-commons-fileupload Commons-fileupload throws an Exception with message Stream closed (Gaahhh, the stack trace is swallowed, I only have the message string! The exception is thrown from FileUploadBase.parseRequest :-( ) Servlet sends an email to admin Servlet returns 200 OK The behaviour seem random but I would say that it fails 80% using the same file, same server, no restart. I attach two pcap-files with a ok-case and a fail-case. The difference I can see is that in the fail-case tomcat starts to send the response before the first Body chunk is sent by Apache. In the ok-case the first Body-chunk is sent by Apache the same millisecond as the first Request packet but in the failing case the first Body chunk is sent a couple of millis after the first packet somehow allowing Tomcat/my servlet to fail before the complete request is received. If we switch the proxyPass to use http everything works 100% of the time (which makes me think I have a misconfig AJP connector somewhere...). Any ideas/pointers are more than welcome! br Svante - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

It seems like this valve does not care if it handles an uncaught
exception or a deliberate exception.
Can this be fixed without patching the valve?
I guess not. I would file a ticket about that: A mere
response#isError call would suffice to wrap that behavior and pass
the response as is.
My understanding is that it is responsibility of the Container to
provide the value for the request attribute
javax.servlet.error.exception
There is simple fix. A examined other server-side component how they set that
attribute and adapted my code.
All you need to do is described in my new ticket:

If your hypothesis is correct , I suspect quite a few people will be in for a shock when they deploy 7.0.27 or later into a production env where memory footprints are much more managed then say in eclipse on your desktop ;) The issue might not be with the spec, but the tomcat implementation where by everything is getting loaded into ram during scanning.

(spring 3.0.7) bunch of very simple examples that end up pulling in many jars. Can you post it to github or somewhere public? p I will grab a dump tomorrow, thanks for response, peter I know exactly where this memory is going. During the scanning process Tomcat has to scan every single class in the application and its libraries and every class and interface in that class's hierarchy for annotations (we don't have a choice in this - the spec requires it). This can lead to the same class being scanned many times during startup and that is slow. Tomcat now caches the result of scanning a class which means each class only has to be scanned once. However, this does mean that all the results are in memory until the scan is complete. If you have a lot of libraries, that could require a lot of memory. If you know a JAR doesn't need scanning, add it to the jarsToSkip property. If it is a popular jar then create an enhancement request and we'll add it to the default list. The other option is to set metadata complete in the web.xml I haven't reviewed the scanning caching code but there may be some opportunities to reduce the memory footprint of the cache.

If they are common jars tell us what they are and we'll add them. - If you do need to scan them the memory usage is the price you pay for fast startup.

Standard stupid question: are you sure you need Apache httpd in the mix? (Gaahhh, the stack trace is swallowed, I only have the message string! The exception is thrown from FileUploadBase.parseRequest :-( ) Is there any way to get the full stack trace? Can you re-deploy with some modified code to get it? I attach two pcap-files with a ok-case and a fail-case. The mailing list has stripped your attachments. Try to copy/paste text into a re-post or post a link to your file(s) instead. The difference I can see is that in the fail-case tomcat starts to send the response before the first Body chunk is sent by Apache. Can you sniff the traffic between httpd and Tomcat? Do you have large headers or anything like that? The AJP message could be rejected because the headers don't fit into a single AJP packet -- but that shouldn't trigger a failure in FileUploadBase. Is there HTTPS in the mix anywhere? Client certs can make the headers large. If we switch the proxyPass to use http everything works 100% of the time (which makes me think I have a misconfig AJP connector somewhere...). Can you post the rest of your AJP configuration?
