Re: Apache 2.2 to Tomcat 6 via proxy_ajp
J. Zimmerman wrote: I am just getting started with Tomcat and have been asked to take on the administration of our Tomcat servers at our college. I am not one of the developers, just the administrator. So far everything has gone pretty smoothly except for getting everything to run proxied via Apache (at least the way we would like it). Our requirement is for Tomcat to deliver the application through http://hostname:8080/appname and/or ajp://hostname:8009/appname. This happens by default and works well. However, we want end users to access the applications via port 443 or 80 and we are doing this via Apache. I can make this work via proxy_ajp and proxy_http so that something like http://hostname/appname works just fine. The wrench in the works is that we want to do virtual hosting through Apache and not have the appname appended to it. The Apache virtual hosted URL's will be the ones exposed to the public. For example if we developed an application called mycoolapp and we were deploying it at a website of the same name we would want the application to run at http://mycoolapp.com and not http://mycoolapp.com/mycoolapp. Inside your virtual host, something like: ProxyPass / http://tomcat.host:8080/mycoolapp/ ProxyPassReverse / http://tomcat.host:8080/mycoolapp/ should do the trick.

A Tomcat installation is just a bunch of files plus some way of starting Tomcat. Your installer could install the files (don't forget you may need to install a JRE as well, as the machine may not already have an appropriate version installed). Your installer could also call the script to create an appropriate service - it depends whether you want to start Tomcat as a service, or whether you just want it started when the user starts your program. Be aware of your user base if you choose to do this.

Is there any way to know whether Apache was contacted using HTTPS or HTTP, on the Tomcat side? I didn't test it, but what should work: mod_ssl automatically sets an internal httpd nvironment variable named HTTPS to on when the connection is doing https. mod_rewrite knows this variable as a builtin (look for HTTPS on http://httpd.apache.org/docs/2.2/mod/mod_rewrite.html), but any other module, that can use data rom environment variables can also use it. E.g. mod_headers has a syntax, where you set request headers depending on an env var being set or not. So you can try to use mod_headers to add a private request header (like: X-MYAPP-HTTPS: yes) to the request, depending on the env var HTTPS being set. You backend can then check for the existence of the header. CAUTION: You can compromise your security with such a header. If your users find out, what the header is, they can send it with the original request and claim it to be HTTPS. To make it bullet proof, you would first have to remove it (and all equivalent headers). I didn't check, whether mod_ssl sets the variable earl enough for mod_request to detect it and mod_proxy to alrady find the new header before forwarding, but I think that's reasonable.

Re: SSI configuration
Ah silly of me; I did read it, but completely spaced over: Only Contexts which are marked as privileged may use SSI features (see the privileged property of the Context element). But it doesn't seem to mention what you say about the global vs local contexts: You must mark your webapp that wishes to use SSI as privileged in its Context element. Unless you want to mark all of your webapps as privileged, do not uncomment the SSI servlet in the global conf/ web.xml; instead, place the SSI servlet definition and mappings to the WEB-INF/web.xml of the webapps that need to use SSI.

mod_jk status code and loadbalancer monitoring
I found a really old entry from way back in 2005. Reading through a trail of messages under the heading Adding working dynamically with mod_jk status What I would very much appreciate is two things. I would like to know where I can get some clear documents on the status codes for mod_jk. The status codes appear in the mod_jk.log file in the following format. [Wed May 20 06:27:47 2009] [21343:33088] [debug] jk_handler::mod_jk.c (1969): Service finished with status=200 for worker=loadbalancer1 I have also seen other entries for status=302 etc. I would like to understand what these status code mean or represent. The second thing that I would like to see is, do you have any information on monitoring the workers in the mod_jk config. I know about the jkstatus function, but that is not very dynamic. It only really reports errors if the wroker is called. I had an issue where I took down on of the two workers in the loadbalancer config, I saw the error that the first worker was no longer available, but as soon as the second worker took over the work, then the error was cleared and nothing more was reported. I have had an idea, but seeing as I am not a programmer, I have no idea how to achieve this, but I hope that someone else has also had the same bright spark. I was hoping that there was some application that did something similar to what webalizer does with the access.log file for the apache web server that could analyze the mod_jk.log file and dynamically report the status of the workers as things happen. Something like a dashboard to show what state the workers are in at any given time. When the log file is rolling in debug mode, there is very much information that could be used to report back on the worker status. I hope that someone might have some good ideas. Somehting that I have also thought about is possibly upgrading the mod_jk version that I am running at the mo. I have the following setup. Server version: Apache/2.0.52 Server built: Jun 29 2007 05:08:11 JK Version: 1.2.15 I get really confused with the different versions and compatibility, so could I keep the current Apache version and only upgrade mod_jk, Where would I find instauction on how to go about doing this.

Re: AJP connections just stop working

Do you have a firewall between IIS and JBOSS? Regards, Rainer Rainer, Thanks for your prompt response! There is no firewall between IIS and JBoss. I will experiment with the connection timeouts, I am thinking I will start with a fairly large number like 10 minutes. One other thing I forgot to mention: When I observed the problem earlier this week, I telnet'd to the AJP port and was able to connect successfully. This was making me think it was not a problem that all the connections were used up. However, I didn't really do anything in the telnet session, because (unlike HTTP) I don't know how to make a simple GET request through telnet, so it's possible it wouldn't have responded. One more question: With my HTTP port, I know I can always easily test it, via my browser or scripted using wget. Anybody know of a simple command-line utility like wget, that works with AJP? I think this would be a good tool to have, to help diagnose AJP problems (and would allow me to easily set up some automated stress tests). Thanks.

I understand that, with keepalive disabled, performance will kind of suck. But, I shouldn't be running out of file descriptors. E.g. if you are doing 2000 requests per second without HTTP Keep Alive and the combination of web server and stress test tool leads to TIME_WAITs, after 15 seconds your table size might reach a critical size. Meaning that the kernel can't keep up, or the NIO connector can't keep up? I suspect the latter, because the other tests under the same conditions at least complete... the NIO one appears not to have a chance. Now, I'm running 6 tests and the NIO test is the 5th one, so it's possible that it's just poorly positioned in my test batter. But, since I've observed this failure at essentially the same place each time, I suspect the NIO connector itself is at fault. Not using HTTP Keep Alive will very likely limit quickly the achievable throughput when going up in concurrency. I'm willing to accept that, but 40 max connections should not be resulting in hundreds of left-open file descriptors. - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.9 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkoWlzUACgkQ9CaO5/Lv0PDtKgCfc9ZOaqcHfvdJHD28wZIiwMAq 52EAn3N1Nk3JoqSOcDkjdlsmJ49t+Yfr =FQdw -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Can you point me to a byte code interpreter so I could look at this?
What you really want is a bytecode disassembler (if that's even the
right term for this thing). I've used 'jad' in the past, but if you just
need to disassemble (instead of decompiling back to Java source),
Chuck's suggestion of using 'javap' is a good one: it's already included
with the JDK and works just fine.

To do this, you can use a placeholder to close the target container, or you can move the script block into the container that you want to modify. You could move your script code to a different place (and probably discontinue using the taglib). I suspect you could easily write this javascript as an external file that you call from wherever you need it. I have a document myself with this rough layout: html body div id=target /div script // call addChild on div#target /script /body /html This works. I think you have a few options, here, besides re-doing everything: 1. Create an empty div that takes up no space, and use that as the target for your addChild. 2. Move the script that you are using to another place in the file (though you might not be able to, given that you're using an onclick event or something... right?) 3. Try something like calling a previously-defined function (at the top- level, under body/script) that does your dirty work. It's unclear to me if the problem is the location of the javascript source that calls addChild or the fact that you are (directly or indirectly) calling addChild from an existing child element. Thanks again, I will have to find another way of doing things, I guess, since it is odd to let users encounter this problem and let them be annoyed about the website not working.

Re: mod_jk status code and loadbalancer monitoring
Hi Lawrence, I will answer in a slightly different order below. On 22.05.2009 13:58, Lawrence Lamprecht wrote: I found a really old entry from way back in 2005. Reading through a trail of messages under the heading Adding working dynamically with mod_jk status What I would very much appreciate is two things. I would like to know where I can get some clear documents on the status codes for mod_jk. The status codes appear in the mod_jk.log file in the following format. [Wed May 20 06:27:47 2009] [21343:33088] [debug] jk_handler::mod_jk.c (1969): Service finished with status=200 for worker=loadbalancer1 I have also seen other entries for status=302 etc. I would like to understand what these status code mean or represent. The second thing that I would like to see is, do you have any information on monitoring the workers in the mod_jk config. I know about the jkstatus function, but that is not very dynamic. It only really reports errors if the wroker is called. I had an issue where I took down on of the two workers in the loadbalancer config, I saw the error that the first worker was no longer available, but as soon as the second worker took over the work, then the error was cleared and nothing more was reported. I have had an idea, but seeing as I am not a programmer, I have no idea how to achieve this, but I hope that someone else has also had the same bright spark. I was hoping that there was some application that did something similar to what webalizer does with the access.log file for the apache web server that could analyze the mod_jk.log file and dynamically report the status of the workers as things happen. Something like a dashboard to show what state the workers are in at any given time. When the log file is rolling in debug mode, there is very much information that could be used to report back on the worker status. I hope that someone might have some good ideas. Somehting that I have also thought about is possibly upgrading the mod_jk version that I am running at the mo. I have the following setup. Server version: Apache/2.0.52 Server built: Jun 29 2007 05:08:11 JK Version: 1.2.15 I get really confused with the different versions and compatibility, so could I keep the current Apache version and only upgrade mod_jk, Where would I find instauction on how to go about doing this. Thanks in advnce Lawrence Lamprecht The status worker was added to mod_jk around the time of your version 1.2.15. It improved *a lot* since then. Actually during the last releases it was the focus of most of the development. So do yourself a favour and update mod_jk. Recent is 1.2.28. Compatibility: mod_jk works for Apache httpd 1.3, 2.0 and 2.2. You need to either compile it against your web server (preferred way) or fetch a binary for your httpd version somewhere, e.g. in our download area. You cannot use a mod_jk for 2.2 to run in 2.0 or vice versa, but the minor digits behind usually do not matter. Compiling is easy (depending a bit on your OS), so you best go that way. We deprecated some configuration attributes long ago, so after updateing have a look at the mod_jk log during startup, if it contains info about not supported or deprecated attributes. The docs contain info about how to replace those. There are only few such attributes. We didn't deprecate anything during the last 10 releases, but chances are, that you should change a few configuration attributes you used with 1.2.15. There is one caveat: JkMount not isn't inherited from the global server to any virtual host or between virtual hosts. If you have virtual hosts, put your JkMount into those or use JkMountCopy. See docs. Now about status codes: The code in the log line you cited is the HTTP status code we return to the client. Those are defined by the HTTP rfc, so 200=OK, 302 is a redirect, 500 is an internal server error etc. In most cases those are simply the ones we get from Tomcat, only if mod_jk detects an error itself it might generate an own status code like 500, 502, 503. Note that the log line is of debug level, so you are not expected to look at those during normal production. JkLogLevel info is enough for production. Any error will be logged at log level error, as long as no message of level error shows up, everything is fine. The info level messages are there to give additional info in case an error level message shows up. Dynamics of status worker: It is as dynamic as it can be. mod_jk doesn't do any probing. If there is an error with a worker we will only detect when there is a request for the worker. In that case, the status worker will immediately reflect the new status. In the latest two versions we started to implement a so-called watchdog thread, that does some very basic probing, namely a cping/cpong connection check for the pooled connections. The watchdog thread might get more powerful in the future. Concerning your observation with taking down one worker in

Instead, you can do something like this: VirtualHost *:80 ServerName mycoolapp.com ProxyPass / ajp://host:8009/mycoolapp /VirtualHost You could also get away with: VirtualHost *:80 ServerName mycoolapp.com ProxyPass / ajp://host:8009/ /VirtualHost ...if you deploy mycoolapp as the ROOT context. - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.9 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkoWp10ACgkQ9CaO5/Lv0PARvQCfVLmzTfeXl7W3xqEc8LOsMXu7 6voAoJizHcvoTPBCgJB9JSqmTeJFSPv2 =2zTC -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

... what is it moaning about?
As you can see this test is based on a tutorial (which is here:
http://www.jsptut.com/Forms.jsp).
My project's directory layout roughly looks like this.
%catalina_home%\webapps\test\test5.jsp
%catalina_home%\webapps\test\WEB-INF\classes\user\UserData.class
the source code for UserData states it's package:
package user;
class UserData implements java.io.Serializable {
private String username;
private String email;
private int age;
public void setUsername(String value) {
username = value;
}
...
}
The jsp for test5.jsp looks like this:
jsp:useBean id=user class=user.UserData scope=session/
jsp:setProperty name=user property=*/
html
body
%=user.getUsername()%br
%=user.getEmail()%br
%=user.getAge()%br
form method=post action=test5.jsp
Name: input type=text value=/br
Email: input type=text value=/br
Age: input type=text value=/br
/form
/body
/html
I think i've isolated the problem to line 1 of the JSP script and know
its a classpath issue. Why is Tomcat not picking up the user.UserData
from WEB-INF\classes, is it because of the lack of web.xml content?
How can get this simple code example to work?
Again I know these questions are nooby but I've been stuck on this
bean stuff since yesterday and am rapidly loosing my patience short
of calling Tomcat 6 a failure. So, any help is very greately
appreciated.
Thanks in advance,
Roderick

Interesting that you expect to get help from people when your first sentence
is designed to annoy them.
java.lang.NoClassDefFoundError: user/UserData (wrong name: UserData)
You compiled your class without a package statement.
... what is it moaning about?
The error message isn't moaning, you are. It's simply letting you know you
made a mistake.
the source code for UserData states it's package:
It does now, but not when you compiled it.
I think i've isolated the problem to line 1 of the JSP script
and know its [sic] a classpath issue.
No, it's not a classpath issue. The UserData.class file in
WEB-INF/classes/user was not created with a package statement.
Why is Tomcat not picking up the user.UserData from
WEB-INF\classes
See above.
How can get this simple code example to work?
Follow the instructions.
am rapidly loosing my patience short of calling Tomcat 6 a failure.
Clearly, Tomcat 6 is a world-wide success. What's your track record?

Look closely. There has to be some discrepancy between what you perceive and what tomcat does. Is UserData.class present anywhere else visible to tomcat? Are you sure you are updating the webapp tomcat is running? Is there any way possible tomcat could be picking up an old copy of your class?

I concur. Just need to find out how the class file is managing to
exist after I've deleted it and shutdown tomcat, its lingering
somewhere thus running javap user.UserData from anywhere still
returns code.
Thanks very much for the help.

RE: Configuring SSI in tomcat 6
i make a backup of everything (with date extension appended) e.g.
web.xml becomes web.xml.22052009
once you have a clean copy configure Datasource as applicationContext-jdbc.xml
web.xml contents:
context-param
param-namecontextConfigLocation/param-name
param-value/WEB-INF/applicationContext-jdbc.xml/param-value
applicationContext-jdbc.xml contents:
beans
!-- Configurer that replaces ${...} placeholders with values from a
properties file --
!-- (in this case, JDBC-related settings for the dataSource definition
below) --
bean id=propertyConfigurer
class=org.springframework.beans.factory.config.PropertyPlaceholderConfigurer
property name=location value=/WEB-INF/jdbc.properties/
/bean
!-- Simple local DataSource that works in any environment.
This uses the JDBC DriverManager to obtain connections, and does NOT perform
connection pooling. Connection pooling is essential to all real-world
applications.
This definition is good for getting started, as it introduces no dependencies
beyond
the JDK, but DriverManagerDataSource is not intended for production usage.
reconfigure this to the DataSource you are using..for the meanwhile we'll use
Spring--
bean id=dataSource
class=org.springframework.jdbc.datasource.DriverManagerDataSource
property name=driverClassName value=${jdbc.driverClassName}/
property name=url value=${jdbc.url}/
property name=username value=${jdbc.username}/
property name=password value=${jdbc.password}/

In all the editing that's been going on, you may have damaged

Worst case, install a clean Tomcat, verify that it's functional, then add
your webapp to it.

Stop Tomcat, empty the logs directory, and restart Tomcat. Does the log

Re: Upload stop after 30 minutes: Processing of multipart/form-data requestfailed. Stream ended unexpectedly
Hmm. This sounds kinda like something we ran into lately -- maybe this will help you: - our server had TWO nic cards, one for internal 10.10.*.* one for external 208.*.*.* - we'd accidentally set up 'default gateway' on both This meant the system was confused as to where to send replies. Looked like a firewall issue, a router issue... but it was just a mis-configuration in the network settings. Ports didn't matter, firewall was okay, router couldn't get a dependable response... E.G. if your IPs are 10.10.10.10/255.255.0.0 and 1.2.3.4/255.255.255.240 then your network knows which interface a packed aimed at 10.10.1.1 should go out on, or where a packet aimed at 1.2.3.7 should go out on. But where would a packet aimed at 222.222.222.222 go? That's when you have a default gateway, which in this case would probably be something like 1.2.3.1. In case this helps.

different behavior in processing jar files in Tomcat 5.0.28 and Tomcat 6.0.18
Hi, In the process of migrating an application from Tomcat 5.0.28 to Tomcat 6.0.18, I've identified a different behavior in processing jar files between the two versions. I've attached a small test application (testapp.war) that can be run under both versions to display the differences. I've also included the appropriate lines from the log files of the two versions below. Essentially, when running my Java code which calls method getResource(String name) of class Class to find a resource that is part of a jar file, Tomcat 5.0.28 finds the jar file in the classpath and expands it in directory jakarta-tomcat-5.0.28/work/Catalina/localhost/testapp/loader. And then I can access the resource in the expanded jar file by calling the getPath() method on the instance of the URL class returned by the getResource(String name) method. However, when running the same code with Tomcat 6.0.18, Tomcat finds the resource in the jar file, but it does not expand the jar file under the apache-tomcat-6.0.18/work/Catalina/localhost directory tree and therefore, I cannot access the resource from the jar file. I've checked the Servlet Specification Version 2.4 (Tomcat 5) and Version 2.5 (Tomcat 6) to see if this should be the expected behavior under Tomcat 6, but as far as I can tell, it should process jar files in the same was as Tomcat 5. If anyone can let me know what the correct behavior should be for Tomcat 6, and if there is a way that I can force Tomcat 6 to process jar files in the same way as Tomcat 5, I would greatly appreciate it.

If anyone can let me know what the correct behavior should be for Tomcat 6, and if there is a way that I can force Tomcat 6 to process jar files in the same way as Tomcat 5, I would greatly appreciate it.

Peering into the pit of jar hell - the mess of tomcat's and other jars in RPM distributions
Sorry to open up with venting, but I truly cannot believe how big of a mess that I found of Tomcat's and others' jars under /usr/share/java in a CentOS 5.2 distribution I examined this morning. For years I've been using tar.gz'd Tomcat that I downloaded and applications I used that had standalone installs would provide similar looking directory layouts of Tomcat. All of those were just great. In the RPM'd Tomcat though, the directories are spread out all over the place (which is acceptable), but from what I've been told, the backporting of patches and possibly attempts to lower the number of the same files (jar files in this case) leave you with a ton of sometimes insane looking symlinks and files. Here is what I'm talking about in /usr/share/java if you're unfamiliar: libgcj-4.1.1.jar libgcj-4.1.2.jar - libgcj-4.1.1.jar libgcj-tools-4.1.1.jar libgcj-tools-4.1.2.jar - libgcj-tools-4.1.1.jar Regardless of how trivial a small change in a version of a jar might be in one case for one version of an application, since this is a shared area for jars, you don't know what some other application would expect out of that jar. And if the person trying to track down an issue thinks they are using one version of a jar, but it is really pointed at a different version. xerces-j2.jar - xerces-j2-2.7.1.jar This seems wrong because you can't assume that, just because you are dependent on a certain jar in one application, the same one would apply to multiple applications. One app might be built with 2.7.1 and another with 2.7.3 that didn't deprecate some method that it removed or changed the signature of, and you might not notice that unless every facet of the jar were tested, and if RedHat or the Fedora community has enough time to do that, they certainly aren't spending their time very wisely. wsdl4j.jar - qname-1.5.2.jar This just looks completely wrong, even if they completely merged the same version of the previous jar into the new one: and servletapi5.jar - tomcat5-servlet-2.4-api-5.5.23.jar This seems wrong on a new counts here as it is a specific implementation and specific version paired with a generic jar name symlink. this one is more excusable than the others though. I don't fundamentally disagree with things often, but I really don't agree that this is a good idea, and it is unfortunately one of the worst messes of jars/dependencies I've seen in my last 10 years as a Java developer (and I've seen some pretty messed up things). How and why could someone RPM Tomcat at all if this is the mess that it falls into?

RE: different behavior in processing jar files in Tomcat 5.0.28 andTomcat 6.0.18
From: Guimaraes, Patricia (NIH/NLM) [C] [mailto:pguimar...@mail.nlm.nih.gov] Subject: different behavior in processing jar files in Tomcat 5.0.28 andTomcat 6.0.18 Essentially, when running my Java code which calls method getResource(String name) of class Class to find a resource that is part of a jar file, Tomcat 5.0.28 finds the jar file in the classpath and expands it in directory jakarta-tomcat- 5.0.28/work/Catalina/localhost/testapp/loader. That's convenience behavior of the container, not defined by the spec. And then I can access the resource in the expanded jar file by calling the getPath() method on the instance of the URL class returned by the getResource(String name) method. The container (Tomcat) is under no obligation to provide any access to the underlying file system (if there is one), other than temporary scratch space. Your use of URL.getPath() - presumably followed by some variation of new File(path) - is risky, and was never guaranteed to work. You should probably be using Class.getResourceAsStream(), which should function properly on any container. - Chuck P.S. Ignore Martin's response - it has no relevance to jars, just to .war files.

RE: Running out of tomcat threads - why many threads in RUNNABLEstage even with no activity
-Original Message- From: Rainer Jung [mailto:rainer.j...@kippdata.de] Sent: Friday, May 22, 2009 2:53 AM To: Tomcat Users List Subject: Re: Running out of tomcat threads - why many threads in RUNNABLEstage even with no activity My point is: persistent connections are good, but connections which are idle for a long time are not as good, so close them after some idle time, like e.g. 10 minutes. Of course this means you need to create new ones once your load goes up again, but that's not a big problem. [Pantvaidya, Vishwajit] Why are connections idle for a long time not good? I thought threads when idle take only a little memory and cpu. Are there any other reasons? Thanks a lot Rainer, Chuck, Chris, Andre, Pid, Martin and everyone else I missed. I spent quite some time yesterday chewing on everything I gathered in the last few days' interactions and the conflicting behavior we are seeing in our systems - that led to following conclusions and action plan: Behavior observed in diff production systems: a. medium-to-large thread count whether firewall exists or not b. % of runnable threads is much higher where firewall between httpd/tomcat c. atleast 1 server where firewall exists has run out of threads d. atleast 1 server where no firewall exists has run out of threads Conclusions: 1. In general, runnable threads should not be a prob, unless they correspond to dropped connections. Since on our servers that have firewall between httpd and tomcat, runnable connections are not being used for new requests and tomcat keeps on creating new threads (leading to #b/c above), those threads could correspond to: i. connections dropped by firewall or ii. hanging tomcat threads as httpd recycle timeout disconnected the connection from that side (and there was no connectiontimeout in server.xml so that tomcat could do the same) or iii. combination of these i and ii 2. Runnable threads on servers where no firewall exist (and we do not see server running out of threads) should not be a point of concerns as they do not correspond to dropped connections, as seen from netstat o/p at the end of this email. So #a above could be ignored. 3. Observation #d above is puzzling and currently I have no answers for that Action: - check both sides by using netstat -anop (Apache side and the Tomcat side without connectionTimeout, so you can see the problem in the original form). See whether the number of AJP connections in the various TCP states differs much between the netstat output on the Apache and on the Tomcat system. - Bring workers.properties settings in line with Apache recommendations: - Worker...cachesize=10 - set to 1 - Worker...cache_timeout=600 - remove - Worker...recycle_timeout=300 - remove Netstat o/p's: connector running on 21005, no firewall between httpd/tomcat Httpd Side: Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program nameTimer tcp0 0 129.41.29.241:53777 129.41.29.48:21005 ESTABLISHED - keepalive (2869.65/0/0) tcp0 0 129.41.29.241:53943 129.41.29.48:21005 ESTABLISHED - keepalive (3341.39/0/0) tcp0 0 129.41.29.241:49950 129.41.29.48:21005 ESTABLISHED - keepalive (6701.51/0/0) tcp0 0 129.41.29.241:49927 129.41.29.48:21005 ESTABLISHED - keepalive (6240.25/0/0) tcp0 0 129.41.29.241:49926 129.41.29.48:21005 ESTABLISHED - keepalive (6239.47/0/0) tcp0 0 129.41.29.241:49971 129.41.29.48:21005 ESTABLISHED - keepalive (6931.40/0/0) tcp0 0 129.41.29.241:49868 129.41.29.48:21005 ESTABLISHED - keepalive (5743.83/0/0) tcp0 0 129.41.29.241:49865 129.41.29.48:21005 ESTABLISHED - keepalive (5741.65/0/0) tcp0 0 129.41.29.241:49867 129.41.29.48:21005 ESTABLISHED - keepalive (5743.16/0/0) tcp0 0 129.41.29.241:49901 129.41.29.48:21005 ESTABLISHED - keepalive (5906.92/0/0) tcp0 0 129.41.29.241:49795 129.41.29.48:21005 ESTABLISHED - keepalive (4659.11/0/0) tcp0 0 129.41.29.241:49558 129.41.29.48:21005 ESTABLISHED - keepalive (1705.06/0/0) tcp0 0 129.41.29.241:50796 129.41.29.48:21005 ESTABLISHED - keepalive (4551.79/0/0) tcp0 0 129.41.29.241:50784 129.41.29.48:21005 ESTABLISHED - keepalive (4539.53/0/0) tcp0 0 129.41.29.241:50711 129.41.29.48:21005 ESTABLISHED - keepalive

Of course this means you need to create new ones once your load goes up again, but that's not a big problem. [Pantvaidya, Vishwajit] Why are connections idle for a long time not good? I thought threads when idle take only a little memory and cpu. Are there any other reasons? Because you might want to monitor connections in order to learn how many threads you need for your load and how things grow or shrink over time. If you keep connections open an infinite number of time, you'll only monitor the biggest need since restart, which is often not very interesting, because it often is artificial (triggered by some performance slowness you might have a very big connection number created during a short time). Second: because they are making trouble so often in combination with firewalls. So in general I like persistent connections as long as they are closed when idle for a longer time. So usually I set the pool min size to 0 and the idle connection timeout to 10 minutes. Thanks a lot Rainer, Chuck, Chris, Andre, Pid, Martin and everyone else I missed. I spent quite some time yesterday chewing on everything I gathered in the last few days' interactions and the conflicting behavior we are seeing in our systems - that led to following conclusions and action plan: Behavior observed in diff production systems: a. medium-to-large thread count whether firewall exists or not b. % of runnable threads is much higher where firewall between httpd/tomcat c. atleast 1 server where firewall exists has run out of threads d. atleast 1 server where no firewall exists has run out of threads Concurrency = Load * ResponseTime Concurrency: number of requests being processed in parallel Load: Number of Requests per Second being handled ResponseTime: Average Response time in seconds. So in case you have a performance problem and for a given load your response time goes up by a factor of ten, the number of connections will also go up by a factpr of 10. That's most often the reason for d) and was the reason, why we asked for thread dumps. Conclusions: 1. In general, runnable threads should not be a prob, unless they correspond to dropped connections. Since on our servers that have firewall between httpd and tomcat, runnable connections are not being used for new requests and tomcat keeps on creating new threads (leading to #b/c above), those threads could correspond to: i. connections dropped by firewall or ii. hanging tomcat threads as httpd recycle timeout disconnected the connection from that side (and there was no connectiontimeout in server.xml so that tomcat could do the same) or iii. combination of these i and ii 2. Runnable threads on servers where no firewall exist (and we do not see server running out of threads) should not be a point of concerns as they do not correspond to dropped connections, as seen from netstat o/p at the end of this email. So #a above could be ignored. 3. Observation #d above is puzzling and currently I have no answers for that If d) happens again, do some thread dumps. Action: - check both sides by using netstat -anop (Apache side and the Tomcat side without connectionTimeout, so you can see the problem in the original form). See whether the number of AJP connections in the various TCP states differs much between the netstat output on the Apache and on the Tomcat system. - Bring workers.properties settings in line with Apache recommendations: - Worker...cachesize=10 - set to 1 respectively when using Apache, remove this. Rely on the defaults for that one. - Worker...cache_timeout=600 - remove - Worker...recycle_timeout=300 - remove Hmmm.

Subject: Peering into the pit of jar hell - the mess of tomcat's and other
jars in RPM distributions
Sorry to open up with venting, but I truly cannot believe how big of a
mess that I found of Tomcat's and others' jars under /usr/share/java in
a CentOS 5.2 distribution I examined this morning.
For years I've been using tar.gz'd Tomcat that I downloaded and
applications I used that had standalone installs would provide similar
looking directory layouts of Tomcat. All of those were just great.
In the RPM'd Tomcat though, the directories are spread out all over the
place (which is acceptable), but from what I've been told, the
backporting of patches and possibly attempts to lower the number of the
same files (jar files in this case) leave you with a ton of sometimes
insane looking symlinks and files.
Here is what I'm talking about in /usr/share/java if you're unfamiliar:
libgcj-4.1.1.jar
libgcj-4.1.2.jar - libgcj-4.1.1.jar
libgcj-tools-4.1.1.jar
libgcj-tools-4.1.2.jar - libgcj-tools-4.1.1.jar
Regardless of how trivial a small change in a version of a jar might be
in one case for one version of an application, since this is a shared
area for jars, you don't know what some other application would expect
out of that jar. And if the person trying to track down an issue thinks
they are using one version of a jar, but it is really pointed at a
different version.
xerces-j2.jar - xerces-j2-2.7.1.jar
This seems wrong because you can't assume that, just because you are
dependent on a certain jar in one application, the same one would apply
to multiple applications. One app might be built with 2.7.1 and another
with 2.7.3 that didn't deprecate some method that it removed or changed
the signature of, and you might not notice that unless every facet of
the jar were tested, and if RedHat or the Fedora community has enough
time to do that, they certainly aren't spending their time very wisely.
wsdl4j.jar - qname-1.5.2.jar
MGwhat is qname? who builds qname? a quick glance at wsdl4j build.xml
contains:
MGjar jarfile=${build.lib}/qname.jar basedir=${build.dest}
MG include name=javax/xml/**/*.class/
MGwho in wsdl4j references wsdl4j?
MG%WSDL4J_HOME%\src\javaxgrep -S -l wsdl4j *.*
MG .\wsdl\OperationType.java
MGonly 1 reference here and thats a comment
MGthat means qname is now the DRIVER (and wsdl4j is supporting library)
MG/* The following equals method is not used within wsdl4j but
MG * it is historically part of the jsr110 wsdl4j API, so it
MG * will not likely be removed. Although it overloads the
MG * Object.equals method (i.e. it has a different arg) it does
MG * not override it, so Object.equals will still be used by
MG * the readResolve method at deserialization.

MGwhat is wsdl4j? who builds wsdl4j? a quick glance at wsdl4j build.xml

MGjar jarfile=${build.lib}/${name}.jar basedir=${build.dest}

MG.\ibm\wsdl\DefinitionImpl.java

MGas you can see wsdl4j functions are empty stubs that call to qname for real
work
MG(the justification for symlink alias of wsdl4j.jar - qname-1.5.2.jar is
validated)
This just looks completely wrong, even if they completely merged the
same version of the previous jar into the new one:

Re: Peering into the pit of jar hell - the mess of tomcat's and other jars in RPM distributions
Martin, Thanks much for the time you spent on the explanation. However (and hopefully I'm being brief also)- one of issues in doing this is that wsdl4j.jar could (in-general) be any version of wsdl4j not necessarily something that just happens to be populated with one or more classes that do nothing more than have methods that just then call classes in (version specific, because method signatures/classes/packages could change in diff versions) qname-1.5.2.jar. (This is - if that is what you are saying- I do not know what version of wsdl4j it is here, nor have I looked at the source, since I don't know what version it is from the name). The impression I get from looking at the mess of symlinks is that people are assuming (like vendors of Windows products that contributed to Microsoft's DLL hell starting mostly in Win95) that playing around with filenames and versions is perfectly acceptable if it gets the job done (for reducing space they take up in an attempt to share files, or in this case possible reducing the stack level by bypassing methods in an interface jar completely). But in fact, when this is done the only substantial good it does that is not outweighed by negatives is that RedHat will end up selling more support licenses for people that get fed up with RPMs on CentOS/Fedora not working properly (after all, they make money off of support, right?). That maybe a fatalistic viewpoint on my part, and I don't mean to start a firestorm, but basically (in this case) unless you were to have a directory that contained a bunch of jars where each filename were to have a version that actually corresponds to the well-known version of that specific jar, then I think you are really asking for trouble.

On 22.05.2009 13:58, Lawrence Lamprecht wrote: I found a really old entry from way back in 2005. Reading through a trail of messages under the heading Adding working dynamically with mod_jk status What I would very much appreciate is two things. I would like to know where I can get some clear documents on the status codes for mod_jk. The status codes appear in the mod_jk.log file in the following format. [Wed May 20 06:27:47 2009] [21343:33088] [debug] jk_handler::mod_jk.c (1969): Service finished with status=200 for worker=loadbalancer1 I have also seen other entries for status=302 etc. I would like to understand what these status code mean or represent. The second thing that I would like to see is, do you have any information on monitoring the workers in the mod_jk config. I know about the jkstatus function, but that is not very dynamic. It only really reports errors if the wroker is called. I had an issue where I took down on of the two workers in the loadbalancer config, I saw the error that the first worker was no longer available, but as soon as the second worker took over the work, then the error was cleared and nothing more was reported. I have had an idea, but seeing as I am not a programmer, I have no idea how to achieve this, but I hope that someone else has also had the same bright spark. I was hoping that there was some application that did something similar to what webalizer does with the access.log file for the apache web server that could analyze the mod_jk.log file and dynamically report the status of the workers as things happen. Something like a dashboard to show what state the workers are in at any given time. When the log file is rolling in debug mode, there is very much information that could be used to report back on the worker status. I hope that someone might have some good ideas. Somehting that I have also thought about is possibly upgrading the mod_jk version that I am running at the mo. I have the following setup. Server version: Apache/2.0.52 Server built: Jun 29 2007 05:08:11 JK Version: 1.2.15 I get really confused with the different versions and compatibility, so could I keep the current Apache version and only upgrade mod_jk, Where would I find instauction on how to go about doing this. Thanks in advnce Lawrence Lamprecht The status worker was added to mod_jk around the time of your version 1.2.15. It improved *a lot* since then. Actually during the last releases it was the focus of most of the development. So do yourself a favour and update mod_jk. Recent is 1.2.28. Compatibility: mod_jk works for Apache httpd 1.3, 2.0 and 2.2. You need to either compile it against your web server (preferred way) or fetch a binary for your httpd version somewhere, e.g. in our download area. You cannot use a mod_jk for 2.2 to run in 2.0 or vice versa, but the minor digits behind usually do not matter. Compiling is easy (depending a bit on your OS), so you best go that way. We deprecated some configuration attributes long ago, so after updateing have a look at the mod_jk log during startup, if it contains info about not supported or deprecated attributes. The docs contain info about how to replace those. There are only few such attributes. We didn't deprecate anything during the last 10 releases, but chances are, that you should change a few configuration attributes you used with 1.2.15. There is one caveat: JkMount not isn't inherited from the global server to any virtual host or between virtual hosts. If you have virtual hosts, put your JkMount into those or use JkMountCopy. See docs. Now about status codes: The code in the log line you cited is the HTTP status code we

No, odules for 2.0 and 2.2 will both be build inside the apache-2.0 directory. It should have been named 2.x some time in the past. This simply comes from the fact, that the module for 2.0 and for 2.2 can be build form exactly the same source. Below that apache-2.0 there should be a .libs directory, that contains the new mod_jk.so file. You then need to find out where your Apache installation keeps its modules.

It only really reports errors if the wroker is called. I had an issue where I took down on of the two workers in the loadbalancer config, I saw the error that the first worker was no longer available, but as soon as the second worker took over the work, then the error was cleared and nothing more was reported. I have had an idea, but seeing as I am not a programmer, I have no idea how to achieve this, but I hope that someone else has also had the same bright spark. I was hoping that there was some application that did something similar to what webalizer does with the access.log file for the apache web server that could analyze the mod_jk.log file and dynamically report the status of the workers as things happen. Something like a dashboard to show what state the workers are in at any given time. When the log file is rolling in debug mode, there is very much information that could be used to report back on the worker status. I hope that someone might have some good ideas. Somehting that I have also thought about is possibly upgrading the mod_jk version that I am running at the mo. I have the following setup. Server version: Apache/2.0.52 Server built: Jun 29 2007 05:08:11 JK Version: 1.2.15 I get really confused with the different versions and compatibility, so could I keep the current Apache version and only upgrade mod_jk, Where would I find instauction on how to go about doing this. Thanks in advnce Lawrence Lamprecht The status worker was added to mod_jk around the time of your version 1.2.15. It improved *a lot* since then. Actually during the last releases it was the focus of most of the development. So do yourself a favour and update mod_jk. Recent is 1.2.28. Compatibility: mod_jk works for Apache httpd 1.3,

It might not produce any problem, but you need more tools installed to be able to run buildconf.sh, than only for the real build. ./configure --with-apxs=/usr/sbin/apxs Make As far as I can see there were no error, I then copied the mod_jk.so to the apache modukes dir. The concern that I have was the location of the new file. /usr/src/tomcat-connectors-1.2.28-src/native/apache-2.0 My apache install is /etc/httpd/ The version of apache I am running is 2.2.3 and the one that was installed for is 2.0? No, odules for 2.0 and 2.2 will both be build inside the apache-2.0 directory. It should have been named 2.x some time in the past. This simply comes from the fact, that the module for 2.0 and for 2.2 can be build form exactly the same source. Below that apache-2.0 there should be a .libs directory, that contains the new mod_jk.so file. You then need to find out where your Apache installation keeps its modules.

We do this on our production systems. Each application gets its own JVM which can, of course, be a different version from the others if necessary (although we try to stick to one JVM for all apps). The same is true for Tomcat: they can each run under a different TC version, or share a single install base (using CATALINA_HOME) with others. It's totally mix-and-match. We do this all using ant scripts to convert a relatively generic set of files along with the code, libraries, etc. into a running instance of Tomcat (whichever version). We can prepare an installation, deploy the web app to it, start and stop tomcat, etc. all using simple ant targets. Once the environment is set up properly, we just run: $ ant install (builds code, prepares Tomcat based upon shared CATALINA_HOME, installs the webapp) $ ant tomcat-start (starts Tomcat) ...and we've got a working application. You can even re-name the application (by changing the project name in the build.xml file) and get yourself a different set of configuration options. So, you can have webapp foo and foo-testing that each deploy to a different Tomcat instance that could potentially be on different JVMs, different Tomcat versions, etc. We are planning to use default appbase and use webapps as directory where users will put in their war files. The data source information should be in the war file itself. And most of the jar's, extra configuration should be built into the war file. The main criteria being that we would like to keep the installation as clean as possible. Exactly why we use the above techniques. Upgrading Tomcat (once we've testing our apps on it sufficiently :) involves nothing more that: $ ant tomcat-stop $ ant install-clean $ (edit environment file to point to the new Tomcat CATALINA_BASE) $ ant install $ ant tomcat-start Upgrade accomplished. If you're interested, I could post samples of the ant scripts we use to perform all this magic. - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.9 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkoXZi4ACgkQ9CaO5/Lv0PAdrwCePRL2g5MVud+IeiPq/t6X0diB s8MAnRB1RplRcwnek0tb8eDb5oAo3GeK =z1TI -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
