Other than a strangely obscure txt file [1], I did not find the concept and usage of Catalina Base documented in the Tomcat docs. Do you mean the CATALINA_BASE environment variable, which is copied into a running JVM as the "catalina.base" system property? Yep, you got it. 2) If not, is there any reason for it not being documented? While I don't want to duplicate text, I do not consider a txt file somewhere a sufficient docs. What, it needs to be in TeX, too? :)) Joking aside though, documentation should say several things at the very least: 1. What it is 2. How to use it 3. When to use it All the documentation links you provided simply say that such variable exists and that you can use it to create multiple instances of Tomcat. So in the HTML docs, I'm missing information on: 1) How do you set it up Well, it's an environment variable so... set it in your shell? There are many ways to set an environment variable. Shall we cover them all? 2) What exactly must be in catalina.base such that Tomcat actually starts (since if you point it to an empty directory, Tomcat fails to start) The RUNNING.txt file explains exactly what must be in CATALINA_BASE versus CATALINA_HOME. Is the primary complaint that this information is not also in the online documentation? 3) What are the advantages of catalina.base, i.e. why does it exist. Saying that 'if you want to multiple instances of Tomcat, use catalina.base' is, in my mind, missing why you'd want to use catalina.base instead of simply copy-paste the whole tomcat directory as many times as you want. I mean, we want to foster good practices, don't we? RUNNING.txt suggests that a split-configuration allows for the "desirable" situation of sharing a copy of Tomcat amongst multiple users. It ignores, however, the most beneficial aspect on a split configuration: ease of upgrading. Perhaps that could be included in the documentation, wherever it ends up . When we have beautiful HTML documentation that is deep and well-written, I wouldn't expect that users are suddenly required to read a shell/bat script, or some txt file that they randomly found while googling, to get full information on catalina.base. Fair enough. So I personally see two options here: 1) We can document it in the Tomcat upstream documentation 2) We can document it in our downstream documentation Having just recently written my own downstream documentation for Apache Solr (whose documentation is indeed also deep and well-written), I'd say that we don't want you to have to do that. (and you might say that the third option is don't document it at all, which I will raise internally and will see what would that yield - I'll take the recommendation of the community very seriously) If the Tomcat community believes that catalina.base is, in fact, well documented, I'm of course OK with that; that's why I'm asking here. What do you think? Do I make sense? :) Makes sense. Where would you have expected to see the documentation for these settings? They are effectively used only from the various launch-related scripts (e.g. bin/catalina.sh|bat and bin/service.bat) but they can also be used in embedded (application) environments, too. So I don't think it makes sense to put that documentation into e.g. the "scripts documentation". How about expanding this section, here: https://tomcat.apache.org/tomcat-9.0-doc/introduction.html#Directories_a nd_Files That sounds reasonable to me. Cheers, I'll see what we can do in terms of documenting it! :) - -chris -BEGIN PGP SIGNATURE- Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQIzBAEBCAAdFiEEMmKgYcQvxMe7tcJcHPApP6U8pFgFAltgYwEACgkQHPApP6U8 pFjN9RAApvnqRPtEtB7OGHSKxcVMSNrlIYmJad5+JQWvfyViFgl3M0/UsDSHV57I rbU+M1PMbdMss/wi3Yul6VY6JFcwDkBNLjYQHCf/r5eAR7ChGl20kXJeTvnUoq1F 6rRqeUey3qzh5CvrvljWsm2ZBj+FuyQZa8RkLSU+h5yiZZqqz9o4ZpypWOqjzoNH Y6YyZitwnYcpzrdKhBBfgWDS/Ly0sed4Vswf4NwCLh6PQB6HR0Xcs/xsY3hQ5WHm TvI5I7F7/lvUhxSVeVOteuMm2qb9aBg15lJmMx6y4Zls+e4HnbPxpcinCmDZ68gV IoG7HRJ1SlUvDQ6TaK7jXGjUuIrM5HA3nn9SajgE3W5S8pO0V/ad0YtMTLWsaXjz AGbFXcrWt1kne8Mg5XcZUHV46Hiwfm3t5R2lzPy/gao+6uEEqdqUIJDfuC5rLvy9 Dk2gPV6bR50QI7bIFgq2p4xYnAR05Md/5T+Dl1qeMnJCUk56kmVRhxZP551/TD9E ED+oM1xLpZ6KowORBG2LbAjuMSGNuEG29lfpGR/B/j9gvdOkwA0jOvEUYUVI1H5O O2YEE6pfU0hS79L0WFFp5I8SbKa8xa4RqdW4lEGseWSvQBoJ/+X5XQZarXqYBaLZ Vw/hRIY6/XIc+mG5ZsZxebGRiM+OzmHnrZ3z97f5AsSGMRYBb1o= =0V/v -END PGP SIGNATURE- -

Re: Tomcat9 ROOT deploy
What I found is when I renamed .xml to ROOT.xml in /conf/Catalina/ then war file exploded in to the ROOT directory in tomcat web apps folder. Is this the expected behavior?? Because when I used as an exploded folder then it referred to it from the same /deploy folder.

What is the correct place to specifiy SPI service files for Java?
Hi all, I would like to get some attention on some older SO-question[1] about where to place SPI-service files of Java. Following the docs, those should be placed in META-INF at the top level of some JAR and webapps designed to be used with Tomcat provide such a folder. But it seems to be ignored during search for SPI-service files, instead those seem to be assumed in WEB-INF/classes/META-INF/services. The can easily be seen e.g. using Process Monitor in Windows. As the SO-question lacks some official Tomcat-documentation or such, I am asking here: What is the correct place for such service files? Can this be configured somehow? Why is META-INF at the top level ignored? Is it used at all for anything or only WEB-INF/classes/META-INF for anything which is normally assumed to be in META-INF itself? Thanks!

The issue is tomcat not picking up war file or neither exploding war file into a directory. But if I unpack war file into a folder then it's picking up properly. War file name is cas##1.0.0.war Host definition in server.xml: Contents of ROOT.xml My tomcat folder structure: -- bin -- conf -- deploy -- cas##1.0.0.war -- logs -- lib -- temp -- webapps -- work Versions: Tomcat 9.0.1 Java 9.0.1 Windows Server 2012 Thanks. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Re: cors filter in WEB-INF/web.xml
Hello Masber, In order to get accurate answers it would be helpful if you could provide details like: - Platform details: OS, jdk/jre, apache-tomcat version... - "I went through documentation" which one? perhaps https://tomcat.apache.org/tomcat-9.0-doc/config/filter.html#CORS_Filter - "my web client still complains" I guess that you get some error response here; have you checked your logs?

That file should generally be in CATALINA_HOME/bin and should match the version of Tomcat is shipped with. If you want to use log4j for logging, I would *always* place the replacement JULI implementation into CATALINA_BASE/lib and leave the Tomcat "stock" installation alone. > 2. $CATALINA_BASE/conf: What files have to be in this directory? server.xml web.xml (though I have argued that this should inherit from CATALINA_HOM E) There are other things that you might want to add, depending upon your needs. > If they are not present - are they loaded from CATALINA_HOME? > RUNNING.txt only mentions server.xml.

Correct. > For other files the situation is not clear, e.g. > catalina.properties, context.xml Both catalina.properties and context.xml will fall-back to CATALINA_HOME if they don't exist in CATALINA_BASE. You may also want to put a static-user file e.g. tomcat-users.xml into your CATALINA_BASE/conf directory. All paths in server.xml are relative to CATALINA_BASE, so if you e.g. configure a like this: Then conf/tomcat-users.xml will be found in CATALINA_BASE. Of course, you can always use an absolute path and put it anywhere you want... it doesn't have to be in that location, though many people will expect it to be there if it's being used. > ...

Do I make sense? :) Makes sense. Where would you have expected to see the documentation for these settings? They are effectively used only from the various launch-related scripts (e.g. bin/catalina.sh|bat and bin/service.bat) but they can also be used in embedded (application) environments, too. So I don't think it makes sense to put that documentation into e.g. the "scripts documentation".

The problem is likely with a component of your application. Logs will help discover the root of the problem. The decision to use Tomcat 8.5 or Tomcat 9.0 has more to do with your risk-aversion. Both versions are still under active development, but Tomcat 8.5 is more mature and stable (from a code perspective, not that it is any more reliable than 9.0). Both versions should be maintained for the next few years.

I have digged deeper now and it seems that the principal object is removed from the session before it is persisted. In StandardSession.java you can find the following comment: /** * The authenticated Principal associated with this session, if any. * IMPLEMENTATION NOTE: This object is not saved and * restored across session serializations! */ protected transient Principal principal = null; This variable stores the authenticated user.

That's the point to ask for some details I'm struggeling with 1. $CATALINA_BASE/bin/tomcat-juli.jar: when do I need to place this jar in this directory? It is only clear to have it in CATALINA_BASE for the documented switch to log4j. From reading catalina.sh I would say it is only necessary to place it in CATALINA_BASE when we want to use a different version. Is this assumption correct? 2. $CATALINA_BASE/conf: What files have to be in this directory? If they are not present - are they loaded from CATALINA_HOME? RUNNING.txt only mentions server.xml. But it looks like we need to have at least a copy of web.xml in this directory too. Reading catalina.sh we also should copy (or link) catalina.policy when running with a security manager. For other files the situation is not clear, e.g. catalina.properties, context.xml, ... Some stackoverflow answers to that question recommend to copy the whole conf directory from CATALINA_HOME to CATALINA_BASE. I'm not sure if this is a good idea if I don't need to change the defaults. The documentation could be improved by listing the files that are mandatory in CATALINA_BASE Regards, Stefan - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
Re: Documentation for Catalina Base
Hi Christopher, thanks so much for finding the time to reply. Find my reasoning inline.

Other than a strangely obscure txt file [1], I did not find the concept and usage of Catalina Base documented in the Tomcat docs. Do you mean the CATALINA_BASE environment variable, which is copied into a running JVM as the "catalina.base" system property? Yep, you got it. 2) If not, is there any reason for it not being documented? While I don't want to duplicate text, I do not consider a txt file somewhere a sufficient docs. What, it needs to be in TeX, too? :)) Joking aside though, documentation should say several things at the very least: 1. What it is 2. How to use it 3. When to use it All the documentation links you provided simply say that such variable exists and that you can use it to create multiple instances of Tomcat. So in the HTML docs, I'm missing information on: 1) How do you set it up 2) What exactly must be in catalina.base such that Tomcat actually starts (since if you point it to an empty directory, Tomcat fails to start) 3) What are the advantages of catalina.base, i.e. why does it exist. Saying that 'if you want to multiple instances of Tomcat, use catalina.base' is, in my mind, missing why you'd want to use catalina.base instead of simply copy-paste the whole tomcat directory as many times as you want. I mean, we want to foster good practices, don't we? When we have beautiful HTML documentation that is deep and well-written, I wouldn't expect that users are suddenly required to read a shell/bat script, or some txt file that they randomly found while googling, to get full information on catalina.base. So I personally see two options here: 1) We can document it in the Tomcat upstream documentation 2) We can document it in our downstream documentation (and you might say that the third option is don't document it at all, which I will raise internally and will see what would that yield - I'll take the recommendation of the community very seriously) If the Tomcat community believes that catalina.base is, in fact, well documented, I'm of course OK with that; that's why I'm asking here. What do you think? Do I make sense? :) Cheers! If the answer to both of my questions is no, we'll create a patch against the Tomcat docs. [1] https://tomcat.apache.org/tomcat-9.0-doc/RUNNING.txt Patches are always welcome, but I believe it is currently properly-documented.
