Re: Tomcat Logging Jarhell
That section just gives some basic info, but nothing that tries to help with what I'm doing. I'm well aware what the directories are for. There are a lot of libraries that my apps have in common, and because of the nature of the project, I need to try to conserve space. By moving jars to a shared spot, I can trim off a decent amount of space. The individual app's code gets updated, but we rarely update the supporting jars, unless it is absolutely needed. It doesn't matter anyways, we can always drop a newer version of a supporting jar in the web app's WEB-INF/lib and it will be used before the others in common/lib or shared/lib get loaded. That's what the documentation says, anyway. 5.5.25 is our standard deployment. We haven't moved up, and perhaps later I'll do that. However, this same problem would arise, regardless of the version, and I was just trying to provide enough about my situation so that I could find appropriate assistance. While I can appreciate some constructive criticism, I'd rather have answers to my questions, as opposed to questions about my design. -- Chris On Tue, Mar 13, 2012 at 4:17 PM, Konstantin Kolinko knst.koli...@gmail.com wrote: 2012/3/13 Christopher Gross cogr...@gmail.com: Hi all.

Re: Precompile JSPs, avoid thousands of servlets?
2012/3/13 Nick Williams nicholas.willi...@puresafety.com: Our second challenge is the 11,500-line web.xml file that results from this process. I understand that Ant does a lot of the hard work for me, but a web.xml file this large bothers me, even if I don’t have to look at it during every day development. What’s more, we’re actually trying to *move away* from having a web.xml file (of any real substance) and using new Servlet 3.0 features. There was a discussion to pack precompiled JSPs as a web fragment, https://issues.apache.org/bugzilla/show_bug.cgi?id=50234 but no code has been proposed to implement that. If you seriously consider this feature to be useful to be used in a real application, you may be the one contributing the code. If you pass an empty web.xml to be updated by precompile tasks, it should not be hard to convert it into web-fragment.xml, using an XSLT transform or just regexp replacements. Though note that a web application that does not use fragments and annotations (and has metadata-complete=true in its web.xml) starts up faster, because Tomcat does not need to spend time scanning the classes and libraries for annotations and web fragments.

If they have to depend on each other, they might just start anyway, keep trying to make contact, and fire a message upon unreasonable delay. Or just return an error status (and hopefully an informative text) when dependent service A is asked for something that can't be done without the help of supporting service B which is not responding. You probably want that sort of fail-soft design anyway. That would be self-contained and independent in my book, since the app. can continue to operate and gives useful (if undesired) responses regardless of what any other app. is doing. Think of it as lazy initialization, driven by user requests instead of startup code. Startup of service or interactive programs should do only what is absolutely necessary to get the app. into a state in which it can respond, since there can be no guarantee that an arbitrary request will *ever* succeed. We have OS services with explicit start-up dependencies, e.g. an issue tracking system which uses an RDBMS, and I'd expect to be able to do this with webapps. Ah, but that's not the same mechanism. There the OS works out the dependency tree and doesn't start service A until supporting service B indicates successful startup. There's no such centralized dependency analysis in a servlet container; the app.s start in any order the container may choose and then stumble over missing dependencies. I think it could be argued that the servlet spec. makes startup ordering by the container an explicit non-requirement, so you couldn't count on it at another site or in another container version anyway.

Not sure what you mean by static class, unless you're referring to an inner class. Regardless, each parallel deployment uses a separate classloader, so the webapp instances cannot interfere with each other. I'm sure he means a class with a static method that returns a shared object (aka singleton, etc.). Yes of course. I mispoke earlier. However, if you've placed classes in a shared library (e.g., Tomcat's lib directory), anything in there will be shared by all webapps. You must be very, very careful when utilizing shared classes, since that can easily lead to unexpected data leakage between webapps (not to mention often making it impossible to undeploy them). Yes, but I would be very surprised if one could cause a different webapp to service a request by doing such a thing. What you might be able to do is get the request *logged* to the wrong webapp, if you were fetching references (say, to the ServletContext) and caching them in the (shared) class, then calling ServletContext.log on them. Aristedes, can you describe in a bit more detail the kinds of things you are doing, here? Also, what kind of logging are you using that suggests your requests are being handled by the wrong webapp? What does JMX have to say about the number of active sessions? (You said that the 'manager' webapp shows a status for the webapp, so you are probably using that session count in your reports, here, but I just wanted to check). I'll focus on trying to get some better logging of the session into the log output and see if we can narrow down the symptoms. Yes, I am using JMX and the Manager app to identify when there are no remaining sessions, and when I therefore should expect to see no further activity at all from the older application. I'll try and get some better information around that by adding logging as you suggest. The logging that we did originally to discover this problem was simple: * sessionless application * we changed the log.properties for log4j in the new app * some hours after we deployed, the old-style log entries were still being written, mixed in with the new ones Aristedes, Did you manage to resolve the problem or narrow down on what is actually happening? p signature.asc Description: OpenPGP digital signature

JVM won't shut down: DestroyJavaVM thread stuck on ??
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 All, I'm sure this has nothing to do with Tomcat, but I figured I'd ask if anyone has seen anything like this before. We use a couple of ant scripts to start and stop Tomcat on our Linux machines. Ultimately, they always call bin/catalina.sh to do the real work or startup or shutdown. Shutdowns are performed by connecting to the shutdown port and saying SHUTDOWN -- there's no process ids or running 'kill' or anything like that. For some reason, our Cocoon instances specifically seem to be having a hard time shutting down: they just sit forever. Tomcat appears to have stopped: all request processor threads have stopped and even the main thread has stopped. All threads are deamons except for this one: DestroyJavaVM prio=10 tid=0x7fa528a77800 nid=0x4b2a waiting on condition [ 0x] java.lang.Thread.State: RUNNABLE No stack trace other than what's shown there: waiting on 0x0, which I'm guessing is a condition that is always false. The only other threads still alive are Cocoon-related and are basically cache-watchers, all sitting idle (again, daemon threads). I'd post the whole thread dump but I already killed the process and forgot to save the dump. This is in a development environment so I wasn't too concerned with capturing everything about it at the time.

Tomcat+SOLR, acceptCount not working
Hi... I am running Apache Tomcat Version 7.0.26 with SOLR 3.5 on jdk1.7.0_03
The problem is that i cannot limit count of connections. I never get connection
refused (only timeouts). For example: maxThreads=150 and acceptCount=100,
as i think i will have 150+100=250 connections in ESTABLISHED state, and all
others will be refused.
But in realy:
#netstat -na | grep 8080 | awk '{print $6}' | sort | uniq -c | sort -rn
3899 FIN_WAIT2
3385 ESTABLISHED
243 TIME_WAIT
9 CLOSE_WAIT
3 FIN_WAIT1
1 SYN_SENT
1 LISTEN

As I think: connections comes to some buffer (may be JVM) and slowly
transferres to TOMCAT... It is not good for my task, the best way is to recieve
250 connections and all other to refuse. How I can do this?

crash with mod_jk 1.2.33
Since October of last year, I have run the mod_jk connector v. 1.2.32. I built the connector myself using Apache 2.2.15's apxs (I also built Apache myself). Today I downloaded, built, and installed the latest mod_jk connector, v. 1.2.33 ( http://mail-archives.apache.org/mod_mbox/tomcat-users/201203.mbox/%3C4F608246.4060601%40apache.org%3E ). This version causes my Apache server to crash when serving most any page I've tried--HTML, cgi-bin/test-cgi, GIF, etc. The only exceptions I've found are Apache's htdocs/index.html page, server-info, and Tomcat served pages. In the Apache error_log I see entries such as [Wed Mar 14 14:54:45 2012] [notice] child pid 7729 exit signal Segmentation fault (11) I am running openSUSE Linux 11.4.

When that failed, I downloaded, built, and installed Apache 2.2.22, then built mod_jk 1.2.33 with the apxs from that version. Again, Apache (this time 2.2.22) crashes with mod_jk 1.2.33, but runs fine with the 1.2.32 connector.

Note that you aren't limiting the number of connections. Note that you

executor.
Read the docs for Connector:
http://tomcat.apache.org/tomcat-7.0-doc/config/http.html
Specifically, read the part about maxConnections.
Also, since you are using AJP on one of those Connectors, your web
server should probably be taking care of connection-limiting at that end.

I didn't time it from the point when I tried to shut it down until I eventually killed the process. The only reason I knew something was wrong was because trying to start-up again I got an error about the connector port being unavailable. That was weird, because Tomcat appeared to have completely shut down, including closing its sockets. Is it possible that one of the daemon threads isn't actually idle, but instead off doing something like waiting on a socket with infinite timeout? (Although I think even that should respond to a shutdown.) That certainly is possible. If I can get it to happen again, I'll get much better data.

Fair enough - I removed the path= entry from the ROOT.xml. I'm assuming when I hit vhost.REDACTED.com, I should see a deployed version of the application.war, right? Or am I doing something blatantly stupidly wrong here? What _do_ you see?

Tomcat HTTPD error pages look different. Are there any relevant messages in the Tomcat logs? Just that the app was in fact unpacked into the work directory (and I can see it there), and it looked like it tried to start (there's a stack trace, but that's application specific - it definitely tried to start, I just don't know where it is) If it didn't start, that would explain why you can't get it to respond. What is the stacktrace? p How have you defined the Hosts in server.xml? Umm, to be honest initially I hadn't. :( I was trying to come up with a way to get 'dynamic' vhost allocation - kick a ROOT.xml and directory structure into place, restart / hup, and the vhost goes live. That doesn't look possible (as it appears I need Host entries in server.xml to do this, which is hard to dynamically edit). Anyway, I created a new Host entry, and added a Valve for logging: Host name=REDACTED.com appBase=REDACTED.com unpackWARs=false autoDeploy=true Valve className=org.apache.catalina.valves.AccessLogValve directory=logs prefix=REDACTED_access_log. suffix=.txt pattern=common resolveHosts=false/ /Host When I hit the host, the vhost is obviously getting handled, as I'm now getting traffic into the REDACTED_access.log, but it's not actually triggering the app: [ec2-user@app01 tomcat6]$ cat REDACTED_access_log.2012-03-14.txt 96.39.62.78 - - [14/Mar/2012:21:58:01 +] GET / HTTP/1.1 404 952 96.39.62.78 - - [14/Mar/2012:21:58:01 +] GET /favicon.ico HTTP/1.1 404 952 Hope that's enough information! -- [key:62590808] signature.asc Description: OpenPGP digital signature

Mine is about 100K small, so I am guessing I am missing something ... I build that using WinDDK so it links to msvcrt.dll instead msvcrtXXX.dll. Anyhow suppose you missed something with win32/win64 environment settings. Try to build directly from 1.2.33-src.zip I fixed the need to run win32 build before win64 so you can build 64-bit directly. Tested that with vs2010 and it builds flawlessly. Just went in and did a nmake (what is WinDDK and should I install it ?)
