Tomcat on Gentoo from the horse, no hear say.
Ok, not even sure where to start so I will kinda just jump in with this. I am not looking to start a flame war, or long thread. I would prefer this thread not to grow beyond this post. As there are better places, like Gentoo java mailing list, gentoo forums, irc, etc. In the Gentoo Tomcat Guide[1] I request users do this before say contacting upstream mailing lists or etc. Like what happened in this case. I am the present maintainer of Tomcat on Gentoo. I started doing so a year ago when I noticed 5.0.27 was the lastest stable, and 5.5.x was pretty far from hitting the tree, despite being almost a year old at the time. The Tomcat maintainer was mia. So I slowly took over and eventually became an official dev. To being with, on Gentoo we compile Open Source Software from source. This is quite common in the FOSS world everywhere except for Java.[2] For some reason you can't get Apache http server binaries, but you can get Tomcat binaries. With that said, compiling Tomcat from source is COMPLETELY different than downloading a pre-built binary version of Tomcat. That has bundled dependencies. As in third party jars not part of Tomcat, but shipped with it. Because Tomcat needs them to run. Now keep in mind not only are we compiling Tomcat from source, we are compiling all of Tomcat's dependencies from source as well. Which leads to considerable dependencies. So package A depends only on B, but to build package B might need/depend on the entire alphabet :) Tomcat 5.5.20, has a ton of build time dependencies with even more optional dependencies. It's not clear if the optional dependencies activate functionality or not within Tomcat. Some of these in question are like Sun's jaf and javamail. Which till recent were not open source or easily available, and could only be obtained as binaries from Sun. So instead of having a potentially limited functionality Tomcat, we provide all possible dependencies, as would be present when Tomcat devs build and package Tomcat. Others can't be bi-passed at all. Try compiling Tomcat with say IBM JDK. You will notice classes are missing. Because only Sun JDK's and blackdown implement JSSE. There is talk of removing that SSL code, and pretty sure has been done with Tomcat 6.0.x. We don't even package JSSE on Gentoo, since it's a pre 1.4 tech. Tomcat is one of the only apps that is using or needs that stuff. Now Tomcat 6.0.x has WAY less deps. A MUCH cleaner and clearer build/compile process. Despite a bit of nastiness still going on. Like naming-factory-dbcp.jar called tomcat-dbcp.jar. Is basically a slightly modified re-packaged and compiled from source commons-dbcp, commons-pool, and commons-collections. Most all Tomcat packagers for Linux distros have voiced their opinion on how that jar is built. So far seem to have fallen on deaf ears. Finally let me apologize for that unfortunately user who decided to post here first. Rather than contacting the proper channels first. Seems there is lots they don't get about the distro they have chosen to run. Much less where to go with questions, problems, or for help with distro provided packages. 1. http://www.gentoo.org/proj/en/java/tomcat-guide.xml 2. http://www.gentoo.org/proj/en/java/why-build-from-source.xml P.S. For anyone that has a real problem with the dependencies. Our build system on Gentoo, specifically ebuilds, are just bash scripts. So one is totally free to modify and attempt to reduce the Tomcat's dependencies on Gentoo. Good luck there, don't think I haven't tried and haven't been there. As is seems to be an issue with our java5 USE flag. Either a dropped dep, or compiling Tomcat as 1.5 source/target is causing catalina.jar to be off a bit. Lacking some functionality or code as it seems. Dropping other deps would likely do the same to other jars. Also pretty sure the only way to get a 1.5 bytecode Tomcat is to compile from source :) Which if one enables the java5 USE flag on Gentoo. Not only can they run under 1.5 jre, but they are running 1.5 bytecode. Upstream binaries are 1.4 bytecode ;) -- William L.

Re: Tomcat on Gentoo from the horse, no hear say.
Despite your request to the contrary, this very long winded message is begging for responses. If all you wanted was for people with Gentoo packaged tomcat to contact Gentoo user's list, you should have simply requested that. On to the comments --- 1. Compiling tomcat. Why??? Java by it's design is one binary byte-code for all platforms. Is there really any reason to build it from source? Well... aside from the Commons-daemon code (jsvc) used to launch tomcat as a service and the tc-native library for the connectors. Those bits of native code still requires a build. 2. The tomcat-dbcp.jar is intended to avoid a classloader collision between tomcat's built-in database pooling functions and Commons-DBCP release builds. I don't see a problem here. 3. Personally I would create one package with tomcat-core as close as possible to what's provided by the tomcat download site and then create packages for all these dependencies. People can opt-in or opt-out of the extra features at their discretion. It would make more of the already built documentation applicable to their setup. Lastly, since the main point of this message is to ask us to steer Gentoo users towards you for questions, we would welcome a representative on the tomcat-users list who could respond to those questions. There shouldn't be a need to make people choose one or the other and most will seek out what they perceive to be the most authoritative source. I see if I google for 'Gentoo tomcat' I get your Tomcat guide as the first result. Too bad google isn't used more often for some of these questions. --David William L.

Make sense ?

You seem to miss entirely the fact that the extra stuff is necessary and needed to BUILD/COMPILE a version of Tomcat equivalent to the binary.

However even if we remove it from runtime, it's still needed at build time. I would suggest anyone questioning this, to go right now and download Tomcat sources.

Lastly, since the main point of this message is to ask us to steer Gentoo users towards you for questions, That was hardly my point.

Gentoo is downstream from Tomcat. If one is running Gentoo, and they have a problem with any application. The first question is, it is a Gentoo specific problem. If so they it should be obvious where to go for help. If it's not, then take it upstream. If unsure, check with downstream before going upstream. Sorry if that's to logical :) Seeing as how we do things a bit differently on Gentoo. Like adhering to FHS there will be Gentoo specific stuff and issues.

Re: Tomcat on Gentoo from the horse, no hear say.
Don't flame, remember it's Christmas. Recompiling Java apps isn't strictly necessary but from a maintainer point of view it makes sense: they want to assure that the distribution they provide is as complete and workable as possible. That includes the ability to build, patch, integrate any software cohesively with all the other packages. Eg: at work I've seen CRM software that bundles it's own JBoss tree and there's no way in hell it'll integrate with an external instance; given your pov it's all right and sound but for me, as a sysadmin, it sucks as I have to accept and track yet another exception to my architectural plan. There's space for bytecode consumers and for source builders, the point is that both should be taken care for; especially if the latter help keeping in touch with the userbase working with your wares. 2006/12/24, Leon Rosenberg [EMAIL PROTECTED]: On 12/24/06, William L.

Again this was an uninformed user griping about dependencies at compile time. Not runtime issues. Btw, when we are on it, can you please remove gcj from the distro? gcj is not officially in Gentoo. There is an overlay, but it's not one of the available compilers at this time. There is no gcj in the main tree that's meant to be used as a jvm replacement.

RE: Peak load of Tomcat-powered server(s)?
Generally in a production environment, increasing the number of threads from the default is compulsory. You need to balance that against the amount of memory that you have allocated for your JVM, which needs to be balanced against the amount of memory available in the machine. Handling concurrent users generally comes back to the number of connections that your architecture can handle and how much work your database server(s) (assuming you have some) can handle. Our experience has been that these things become an issue before tomcat does. It depends on your application *a lot*. Nothing beats real load testing to figure out where *your* stress points are. They are probably going to be different to other people...

Re: Peak load of Tomcat-powered server(s)?
Again it depends on many parameters, not at least on your hardware. With good x86_64 hardware and with fair amount of dynamic requests, probably between 1000 and 3000 concurrent users depending on how many requests each user triggers. but of course its purely speculating, your app could serve 100.000 users on each server or just 100, it depends solely on your app. leon On 12/25/06, Li Ma [EMAIL PROTECTED] wrote: Thanks for the suggestions.

On Sun, 2006-12-24 at 22:03 +0100, Leon Rosenberg wrote: Well yes, but maybe this is for a reason, like it simply doesn't work with another version? Good point. If that is the case, we depend on an older version that does work. And/or we report back to upstream with patches or etc so the sources can be modified to work with newer versions of dependencies. That's not quite true :-) Each day there are at least 2-3 people on the tomcat irc channel claiming having problems with tomcat, which results in using package from a distro or gcj. Not all from gentoo though :-) Well jasonb on the Tomcat IRC channel knows me pretty well. Even met him in person this last summer in CA. Pretty sure he will forward any Gentoo related chatter on IRC to the proper Gentoo channels. I have requested this, and if any here are on IRC and see someone talking about Tomcat on Gentoo. Send them our/my way please. Saves us all grief :) Exactly there we have a problem. If I have 2 apps demanding different versions of stuff, I don't want to break the first by simply installing the second :-) Another good point. On Gentoo we do what we call slotting. For example Tomcat is slotted, 5, 5.5, and 6. So one could have all three installed. Same goes for dependencies. So we can make sure we have the right versions of dependencies. Not to toot our own horn. But we really have allot of revolutionary stuff going on in Gentoo with regard to Java. There is so much more than stated here. Most of this stuff like versions of dependencies, or slotting are core Gentoo concepts. Nothing specific to Java. But we have all kinds of Java specific goodies, tools, and a very well thought out and planned system. So you have a complex automatic regression test suite to ensure that your apps will run in the next version? Than I assume you have never shiped a 5.0.x version above 5.0.19, since there was never a working version in 5.0. branch after 5.0.19. Not sure what you mean there. There was an official 5.0.28 release. However I came in around the Tomcat 5.5.17 days, and at that point anything 5.0.x was quite out dated. Although I have run Tomcat since leaving JRun back in the 3.x days. Just not on Gentoo, was RH back then. Tomcat on Gentoo was just not being maintained and fallen behind. But as far as regression testing. We don't get crazy with that. Again we are a all volunteer effort. We tests as best we can. We either stick stuff in an overlay or in the unstable branch of our portage repository for users to test out and provide feedback on or etc. Then if a package goes 30 days in the tree with no bugs, it can be stabilized. Might sound crazy to leave it up to users, but that's how TC 6.0.x is being developed and tested right now. This is how open source stuff works. Rarely is there a corp entity behind all this, with test tools, and etc. Than gentoo is a lot better than debian or suse. With regard to Java, there is no implementation in the world like what we have on Gentoo. Again not bragging, go look at our implementations with like our java-config tool. We have system vms for running apps, compile time vm's. We allow control over source/target during building, and so much cool, important, and useful stuff. I really don't recall how I ever went on without it all :) But what my post is really about is: distros are good for stuff you don't want to mess around with, like kernel, standard services or security patches. But as soon as you seriously work with java, the distros aren't sufficent. Gentoo just might be. Take a look. There really is quite allot going on, but very few of us making that happen. Help is always welcomed and appreciated. I assume a vlc developer doesn't work with vlc or codec packages from the distros either.

JSP Reload problem (wierd)
I am using WinSCP to open and edit jsp's on my remote Tomcat server. I open the file from the server to edit and add a hello world into the Login jsp. Then I request the page in IE 6 and it loads the page and hello world is displayed. The page loads within a second (is this enough time for a jsp to compile ??!). Then I edit the file in WinSCP again to remove the hello world from the login jsp, and I click on ctrl + refresh in IE6. The login page reloads almost immediately and hello world is still displaying. I hit ctrl refresh over and over, and cant get rid of hello world. I check Login.jsp on the server ant hello world is definitely not in there. I go into the work directory tomcat5.0/work/Catalina/localhost/myWebapp and notice that the Login_jsp.java file is 3 hours old. I delete this as well as the Login_jsp.class file. I try reload the page (ctrl +refresh). Hello world is still displaying. I look in the work folder. No new Login_jsp.java file, and no new Login_jsp.class file. I add aagh into the Login.jsp file. Hit reload in explorer and aagh displays. But there is still no new Login_jsp.java file, and no new Login_jsp.class file If I rename the file to Login1.jsp and then click on reload in IE6, after the third attempt Tomcat realizes there's no JSP file and logs an error in catalina.log. Then if I rename the Login.jsp back to Login.jsp, tomcat reloads the file and displays it correctly. What is going on?? I feel like I'm in the Twilight zone. __ Do You Yahoo!? Tired of spam? Yahoo!

Re: JSP Reload problem (wierd)
Hi, This is usually a problem with IE, it caches your pages for you. This might be the reason. Try doing the same in some other browser. (Firefox usually doesnt cache the pages.) If u still have the problem in other browsers, you might have to enable autoreload in tomcat to recomplie jsps or reload classes whenever there is a change to the file. Hope this helps.
