Re: Deploying/Undeploying application using the manager webapp
We just chased down a problem with the struts jar file being locked after being removed by the manager. The solution I found in the struts mailing list archives was to add the dtd files from the struts jar file to WEB-INF/classes as a work-around. Maybe that will get you pointed in the right direction on your locking problem. Good luck. Best Regards, Jason Koeninger JJ Computer Consulting http://www.jjcc.com Rais Bonny wrote: Thanks again.

Anyway, that is where I'd look first. Tomcat also uses commons-logging heavily and commons-logging uses classloader tricks in various places. I can see where Tomcat might think that it it needs to hold onto commons-logging resources and get the ones loaded from your WEB-INF/lib mixed up with other ones in the classpath. You just never know. What I'd do is attempt to remove the app via the manager app. After this, go and try to manually delete parts of the webapp directory structure to see exactly which files are locked. Once you do this, you will have narrowed down which libraries are holding onto resources long after they should be. You may have to call some shutdown method(s) using a servlet context listener or something. Jake At 01:39 PM 6/3/2003 +1000, you wrote: Jacob, Thanks for the reply.

RE: mod_jk leaves connections open?
Someone correct me if I'm wrong, but mod_jk using the ajp13 and later protocols is supposed to leave connections open. One of the reasons behind the change from ajp12 to ajp13 was to get away from opening a connection to Tomcat for every servlet/jsp served by Tomcat. If you're having trouble with lockups at a certain number of connections, you probably need to tune the Tomcat thread pool (server.xml), Apache/IIS, and/or the underlying operating system. Keep in mind that resources can be quickly exhausted when running IIS/Apache + mod_jk + Tomcat + your application + database + etc. all on one machine.

Re: Tomcat 3.3.1 - Sessions Migrating Between Users
I've been doing multi-threaded code for a long time, and while I'm not going to say there's no way I made a mistake, I am going to say that it's unlikely it's a threading issue. In this particular application, I do session management in a single servlet, and all I do is log the user on and place the user object in the session. I'll double-check it, but that's how it was originally written. Any other thoughts?

Is that the latest version of the 3.3 branch? If not, you could try to upgrade. Doubtful. Previous upgrades caused some painful problems. You'll find my ajp13 issues on Tomcat 3.3.1 in the archives. In fact, if feasible, you might just upgrade to an entirely new version, and see if the problem persists. There's a 4.0 branch (up to 4.0.4) and a 4.1 (up to 4.1.11 already or soon). Both those versions implement the latest servlet/jsp specs (2.3/1.2) (3.2 and 3.3 implement 2.2/1.1). And the ajp12 protocol (I think that means version 1.2 of the AJP protocol) has been replaced by ajp13 (likewise, version 1.3 of the AJP protocol). Actually, I went running back to ajp12 after my last experience with ajp13. This is, in fact, a similar problem to my last ajp13 experience in which you could get results from old requests. Odd problem and difficult to describe, and it made you think you were insane when you hit reload and all was better. I think I'll try bypassing Apache and going straight to Tomcat for now. If that doesn't work, it looks like we'll try the 4.x branch finally. Thanks for the help.

Re: one last plea for help
I believe it's a bug in the connection pool in ajp13, and yes, I've seen it. I'm not sure if newer versions fix the problem or not, but an easy fix for it is to switch to ajp12 which uses a new connection for each request. It's reportedly slower, but I haven't had any problems with it on Tomcat 3.3m3 or Tomcat 3.3.1. I've never run Tomcat 3.1 so YMMV.

The request is decrypted by apache, then sent over the connector to tomcat. Tomcat processes the request, and sends the result back over the connector to apache. Apache encrypts the response, and sends it back to the browser. So, to setup SSL on apache, use mod_ssl.

Re: Tomcato4.0.4 and included jsp compilation problem
No, it doesn't compile the included JSP every time. The difference is that with static includes, the code is included directly into the servlet created by the JSP. With dynamic includes, the output of the included JSP is generated at the point you include it and sent to the client. It's a very slight difference in performance unless, of course, you have a lot of nested static includes that you convert to dynamic. Looking at the .java files generated in the work directory of Tomcat for your web application makes it more clear how static vs. dynamic works. Touch utilities are generally included in most Unix/Linux systems. Do man touch to get more information. If you're on Windows, I'm not sure what the equivalent would be.

Re: many java processes
I missed a lot of this thread, but given some of the comments made, I thought I should post some information. FWIW, these discussions take place frequently and can be found in the list archives. The Linux thread implementation represents a thread as a process. That's why you see tons of processes when any Java application is running. Unlike a normal process, though, all of these processes share the same address space so the memory use you see in ps or top is really shared across all of the processes. As far as Sun fixing something, I'm not sure there's something to fix, but I do believe some JVM's have a green threads implementation that runs multiple threads on a single Linux thread. There may also be other threading models under development for Linux. I know IBM was working on a more Solaris-like MxN threading scheme, but I don't keep up with Linux enough to know the specifics of any of those projects.

Re: coyote httpconnector design
I have a few curiosity questions if you don't mind. First, what's your test configuration? What platform is the machine below running, and what else is running on it? Also, are you running the load generator on the same machine or on a different machine? Second, have you checked to see if the system is swapping memory during your tests? And, what JVM are you using? Below, I noticed you said you were going to see how fast static content would work. It might be as or more interesting to measure a servlet doing the same work as your JSP pages. I know that it's supposed to run just like a servlet after the compile is done on the first request, but it would be interesting nonetheless to remove that overhead and look at the differences. Anyway, just curious for my own information. I'll be having to do some load testing of my own in the next couple of months so this would be timely information.

McClanahan wrote: Here is a little background on why I am looking for the information. I've been doing some performance benchmarks comparing coyote and httpconnector on 4.0.2 and 4.0.3 with JSTL. My test pages use a lot of includes to dynamically build the header, footer and look of a page. when I used include directive %@ include file= % the performance for 4-16 concurrent connections causes dramatic increases in CPU utilization. When I use action include as in jsp:include page=/ the performance is better. Tomcat is running on a resource limited box, 600mhz w/256Mb ram. Hmm, this result is a little counter-intuitive. The %@ include % directive causes a single (larger) JSP page to be created -- like the #include directive in C code -- versus multiple independent pages that are linked via RequestDispatcher.include() calls. I'm wondering if the resource limited part of your description is kicking in. It would be useful to compare all four combinations: - Old connector, include directive - Old connector, include action - New connector, include dirctive - New connector, include action Before I saw the results, I expected include directive to perform better. Actually I did several series of tests, including the ones you suggested. My guess is it's a combination of the code generated and the thread management causing the CPU spike. One noteable detail is for 32+ concurrent connections, coyote's CPU usage occasionally went down to zero. The CPU drop had a direct effect on the response time. Here are some numbers. All times are miliseconds. include directive - 1 thread 1000 iterations - httpconnector ave - 33 cpu usage - 40-70% action include - 1 thread 1000 - httpconnector ave - 81 cpu usage - 60-85% include directive - 2 threads 500 - httpconnector ave - 453 cpu usage - 85-100% action include - 2 threads 500 - httpconnector ave - 299 cpu usage - 80-100% include directive - 4 threads 250 - httpconnector ave - 27273 cpu usage - 100% coyote connector ave - 590 action include - 4 threads 250 - httpconnector ave - 738 cpu usage - 95-100% coyote connector ave - 211 cpu usage - 15% less than httpconnector include directive - 8 threads 125 - httpconnector - failed to complete cpu usage - 100% coyote ave - 1546 cpu usage - 80-100% action include - 8 threads 125 - httpconnector ave - 1867 cpu usage - 95-100% coyote ave - 370 cpu usage - 90-100% action include - 16 threads 63 - httpconnector ave - 1323 cpu usage - 95-100% coyote ave - 792 cpu usage - 95-100% people2.jsp - 32 threads 63 - coyote ave - 1215 cpu usage - 95-100% Simple jsp page that prints out http headers java and jstl to print req param 1 thread 1000 iterations - httpconnector ave - 10 cpu usage - 20-30% 2 thread 500 iterations - httpconnector ave - 11 cpu usage - 30-40% 4 thread 250 iterations - httpconnector ave - 16 cpu usage - 40-60% 32 threads 65 iterations - httpconnector ave - 252 coyote ave - 84 64 threads 35 iterations - coyote ave - 136 Using include directive, the compiled class file gets close to the 64K limit (around 61K).

1) None of my servlets use multithreading.. I'm new to Java and haven't learned that
yet.
2) A database connection is opened as soon as necessary in the servlet and I expect
it to remain available until the servlet closes. I do not expect it to be available
across multiple

Here's the code for the 3 routines plus the database connect and disconnect (please

RE: Where to place JDBC drivers? How?
There are variations between versions of Tomcat on how things work. For instance, Tomcat 3.2 recognized things in the classpath whereas Tomcat 3.3 doesn't. 3.3 has directories in its installation where jars can be added globally. I don't know how 4.x handles it.

Re: specifying remote Tomcat

Two things I would do to figure out the problem. First, pull out the Alias and Directory entries below. Sounds to me like they're taking responsibility for the /examples url. Second, I've never seen a Tomcat JkMount command with the URL-style protocol and IP specification. The workers.properties file handles the IP address, port number, and protocol. You just provide the name of the worker. What you provided looks like stuff from JServ, and I'm not sure it's still part of mod_jk. Hope that helps.

You say you're not getting errors and it's going straight to examples without going through Tomcat. There's an Alias entry dealing with the /examples URL so my recommendation is remove it and see if Apache starts going to Tomcat. If it does, you've found the problem and can start working toward a solution.

Re: mod_jk Virtual Host Problems
I may be mistaken, but this is an Apache problem, isn't it? To do name based virtual hosts in Apache, you have to have a NamedVirtualHost (not sure if that's exactly the right directive) entry that gives the IP where you'll put the hosts. Then, the VirtualHost entries have to use that same IP address in their declaration. I'm not sure you can get away with the asterick like that, but I could be wrong. Given that you're only getting the response from the first one, I'm going to guess that Apache's not getting to the others. Try some html files in your document roots to see if it's Apache or if it's mod_jk.

Re: Multiple JVMs, mod_jk, and identical context names
All you need to do is put your JkMounts in their appropriate VirtualHosts and either include the LoadModule, AddModule, JkWorkersFile, JkLogFile, JkLogLevel (not sure if those are exactly right) outside the virtual hosts and before the JkMounts or just do everything inline in httpd.conf. Something like this but don't quote me on the exact syntax and directive names: LoadModule jk_module libexec/mod_jk.so AddModule mod_jk.c JkWorkersFile /path/to/workers.properties JkLogFile /path/to/mod_jk.log JkLogLevel error VirtualHost 127.0.0.1 ... JkMount /custom_name1 ajp12_custom JkMount /caffeine ajp12_custom /VirtualHost VirtualHost 127.0.0.2 ... JkMount /custom_name2 ajp13_custom JkMount /caffeine ajp13_custom ... /VirtualHost That sounds about like what you're trying to accomplish. Obviously, I've left some stuff out, but you should be able to fill in the blanks.

Suse Linux 7.0 JDK 1.3.0 Apache 1.3.19 Tomcat 3.2.1 I am using mod_jk and I have a workers.properties-custom file that creates two more workers (ajp12_custom, ajp13_custom) on new ports (8011 8013 respectively). They are added to the worker.list and load balance list. This file is referenced in my custom mod_jk configuration file (mod_jk.conf-custom) as the correct worker file. I also have two custom server.xml files which are used to startup and shutdown using the -f flag to the startup.sh and shutdown.sh scripts. Each server.xml file has two (2) application specific contexts, one of which is identical in name only, between both files: server.xml: --- /custom_name1 /caffeine server_custom.xml: /custom_name2 /caffeine The /caffeine context, whilst the same in name, needs to point to different locations for each webapp. They cannot be shared. Everything works correctly, apart from when the /caffeine context is accessed in each webapp. I realised that I have a common mod_jk.conf-custom file that of course only has the one /caffeine configuration block. In my haste I set the connector for /caffeine context to be the new ajp13_custom, which only works for one webapp and not the other. So, the question is really... I'm not sure how to best do this? I've tried declaring two (2) mod_jk.conf files: mod_jk.conf-caffeine mod_jk.conf-custom and set an Include statement for each virtual host declaration in my Apache httpd.conf, instead of a global Include as I had previously, however I get the following error when trying to start Apache: Syntx error on line 8 of /usr/local/tomcat/conf/mod_jk.con-caffeine LoadModule connot occur within VirtualHost section ./apachectl start: httpd could not be started This is the line that loads the mod_jk module /libexec/mod_jk.so Does anyone have any suggestions? thanks in advance Stu

You say, you want to connect Tomcat to Apache. Then you should do virtual hosts in Apache, not in Tomcat. I would have to disagree on this point. How successfully Tomcat does this in all situations is a different matter, but I think a lot of people want to do something like this: VirtualHost 10.0.0.1 ... JkMount /*.jsp ajp13 ... /VirtualHost VirtualHost 10.0.0.2 ... JkMount /*.jsp ajp13 ... /VirtualHost In this case, Tomcat has to know about the virtual hosts to have two unique root contexts. In fact, I've set up a system this way with the 3.2.3 version, but I couldn't get the same thing to work when separating the Apache and Tomcat machines from each other. IMHO, Tomcat should be looking at the contents of the ServerName field on requests from Apache to determine what host to use in its own configuration. Otherwise, you're stuck with running multiple instances of Tomcat like I am right now, or you're forced to run it on the same machine as Apache (and I have no idea why that works). Note: I did get this to work to an extent with machines separated, but it didn't reliably work under different forms of requests (HTTP 1.0 instead of 1.1 for IP-based hosts, IP instead of named-based hosts with the IP in the URL request instead of the name, and a few others that I forget).

The precise content is selected by a parameter, e.g: http://host/servlet/get?p=1 Accessing the servlet from Tomcat standalone, everything works fine. However, when using mod_jk (AJPv13) to access Tomcat from Apache, things work well until after the server has been under heavy load. Once the server has been loaded up, I start getting bizarre behaviour: Apache will return the output of the *previous* servlet invocation. Given the sequence: http://host/servlet/get?p=1 http://host/servlet/get?p=2 the first request will return some old result and p=2 will return the result expected from p=1. From my servlet logs, I know that the p=1 request reaches the servlet and the right content is generated (and I can confirm this by accessing the servlet directly on port 8080, by-passing Apache). But Apache resolutely returns the old content. This feels like some kind of buffering problem - perhaps in mod_jk, or maybe in Apache itself. Has anyone else seen anything like this?

Re: Running more than one instance of Tomcat on the same machine
On the 3.x series, there's a command line switch to tell Tomcat where it should look for its configuration file. That way, you just keep everything in the same directory and have multiple server.xml files.

Re: FRUSTRATED: Is my_mod_jk.conf Only Way
- server.xml configures Tomcat. - mod_jk.conf-auto is created by Tomcat based on your server.xml configuration and can be included in Apache's httpd.conf. or - My preferred way is to put all of the mod_jk directives in httpd.conf myself and maintain them manually...no surprises, but others have luck with the automated method. - workers.properties is used by mod_jk to figure out how to connect to Tomcat (IP address, port number, load balancing, etc.). If everything's on the same machine, the default file is fine. You can use ajp12 or ajp13 workers by those names from the default settings. - uriworkermap.properties is IIS/ISAPI only...I think. No need to worry about it. The only other file I've had to mess with is tomcat-users.xml to set up authentication through Tomcat on one site where a webapp relied on it. Otherwise, I just stick to Apache's security. Hope that helps. Best Regards, Jason Koeninger JJ Computer Consulting http://www.jjcc.com On Mon, 02 Jul 2001 19:26:59 -0600, Joseph A.

Re: mod_jk load-balancing and errors
What version are you using? The mod_jk I'm using that was compiled from the 3.3m3 distribution seems to be handling dropped connections better, but my system isn't load balanced. As far as option (a) below, I think ajp12 does that (makes a new connection each time) which is what makes it slower than ajp13.

So far it works, I get nice, even, balancing of requests between Tomcat servers. All is fine until I shutdown one of the Tomcat servers... When I shutdown one of the Tomcat servers I'm load-balancing to, I get a few errors, and then everything is fine. I assume that this is because mod_jk keeps a pool of open connections to the Tomcat servers, and then when it tries to send a request down one of the connections to the absent Tomcat server, it returns an error, and then closes that connection. What I am trying to do is eliminate these errors I get when a Tomcat server goes away. I tried placing a hardware load-balancer between Apache and Tomcat, but then discovered that I ran into the same problem thanks to the pool of persistent connections. It would be great if mod_jk would either a) Make a new connection to Tomcat for each request so that a hardware load-balancer can be placed between the two and will only direct requests to the Tomcat server(s) that are functioning... or b) mod_jk smart enough to not send a request down a dead connection.

RE: apache mod_rewrite, mod_jk
Yes, but the logs below and the error message you get are showing Tomcat seeing /hello. That shouldn't be happening with what appears to be a good configuration. Something else is going on here.

Virtual Hosts
Let me see if I can take a different approach on these questions. I've done a few different configurations for virtual hosting and haven't been very pleased with any of them. So, what I'd like to know is how people on this list recommend you do virtual hosting. In our particular situation, we have Apache 1.3.19 with mod_jk on one system and Tomcat 3.3m3 on another. There are both name-based virtual hosts and virtual hosts with unique IP addresses on the same system. I have several ideas I plan to try to fix some problems I've run into, but I'd appreciate any recommendations from the list before I waste a lot more time. Just to let you know, I've tried using Tomcat's built in virtual hosting and was reasonably successful if Tomcat was on the same machine as Apache. However, IP address-based hosts with my current configuration are exposing JSP code when the IP address is used in the request. I've used mod_rewrite to rewrite the URL, but I still have problems on clients that don't send the HTTP 1.1 request that includes the host name. Once upgraded to Tomcat 3.3m3, name-based hosting seems to work fine in this setup, and any potential problems will likely be worked out with mod_rewrite. However, some clients want an IP. So, my next thought is to alias private IP addresses to the Tomcat machine for each unique host and use different workers for each host in the JkMount directives in the VirtualHost sections of Apache's configuration. The down-side to that is in Tomcat 3.2, I was having to include Host entries in server.xml for each unique IP and each unique host name. Anyway, if you have any recommendations, I'd love to hear them. If I had the time, I'd just dig into the code and figure this stuff out, but I don't have the time just yet.

RE: server side includes, tomcat and jsp files
It would probably be best to use Java's include calls as identified in another e-mail, but I did find the following statement in the Apache documentation: For backwards compatibility, documents with mime type text/x-server-parsed-html or text/x-server-parsed-html3 will also be parsed (and the resulting output given the mime type text/html). Maybe if you modify the mime type the JSP pages generate, you'll get Apache to process it. Don't really know, though. It depends on how mod_jk works together with Apache and SSI. It's important to keep in mind how Apache works with Tomcat. Apache doesn't serve the jsp files, it serves a data stream coming through ajp12 or ajp13 from Tomcat. As a result, it would have to touch the data after Tomcat returns it, not the file before Tomcat processes it. Hope that helps. I really would recommend you consider using the Java approach. It would probably be less of a headache.

Re: Apache and Tomcat on different boxes
The ip address or hostname of the Tomcat machine is stored in the workers.properties file referenced by your mod_jk setup. I've also seen some sort of url version of the JkMount command, but I've never used it myself and don't know if it works or what versions it works on.

Re: Apache and Tomcat on different boxes
The only thing I see missing are the following directives from httpd.conf: JkWorkersFile /usr/local/apache/conf/workers.properties JkLogFile /usr/local/apache/logs/mod_jk.log JkLogLevel error I would assume those are probably in there, but I just wanted to clarify that you have to point mod_jk to the right workers.properties file for your changes to take effect. These directives are ones I put in. I'm not sure what the docs say to use. They may well point to the Tomcat conf directory instead of the Apache conf directory. If so, the file you put in Apache's conf wouldn't work. Anyway, good luck.

RE: Apache and Tomcat on different boxes
The workers.properties file should be on the Apache machine. The problem you're running into is that the documentation usually assumes Tomcat and Apache are on the same machine, and it's leading you to believe that workers.properties has something to do with Tomcat. workers.properties is only relevant to mod_jk running on Apache, not to Tomcat. If you need the example file provided with Tomcat, just copy it over to the Apache machine from a distribution of Tomcat and point JkWorkersFile to the right place on the local file system. And yes, it does work. I've run several development and production systems this way.
