I'm afraid so. But I hope this is not about packaging, but about

There seem to be two, but I have never used or touched examples.

:-) I'd rather compile from scratch, but that's just the way I was

I would if I knew what to look for :-) In /var/log/tomcat there are:
• a catalina.out but it's empty
• hundreds of host-manager.-mm-yy.log, all empty
• hundreds of localhost.-mm-yy.log, all empty
• hundreds of localhost_access_log.-mm-dd.txt, between 10–20MB each
• dozens of catalina.out-mmdd.gz, 20 or so bytes each
• dozens of catalina.-mm-dd.log, 30-100KB each
• one catalina.out, empty
I realise this is probably CentOS's or RedHat's doing :-)
A typical catalina.-mm-dd.log starts with

Config file weirdness for additional applications
I am serving Cocoon as my default app under Tomcat5 on RHEL5 using a virtual host implemented in the Apache httpd.conf. This is now working fine (thanks to the explanations of others on this list!) I now have to add another app, OpenClinica, in its own virtual host, so the DNS entry was made, and the httpd.conf section set up, and a Host element added to /etc/tomcat5/server.xml (where RHEL puts it). The OpenClinica.war file was deployed, and a new directory appeared in /etc/tomcat5/Catalina called openclinica.ucc.ie containing a file called OpenClinica.xml The OpenClinica docs said the file would be at /usr/local/tomcat/conf/Catalina/localhost/OpenClinica.xml but in the light of where RHEL dictates stuff should go, and the fact that we are using a virtual host, this seems to be right. The file was edited to reflect the database username and password. Then I found that Tomcat had also created another identical file in /etc/tomcat5/Catalina/publish.ucc.ie (our virtual host for the default Cocoon app). I don't understand why it did this, and it's unclear why it would want to, and it's also uncertain which one it will read. No such equivalent file was ever created when deploying Cocoon as the default app. Does anyone have a suggestion as to what we are doing wrong? The OpenClinica app fails to authenticate to Postgresql, but that's a separate matter I have raised on their own list. It's the duplicate creation of the config file in two places at deployment time by Tomcat that puzzles me. ///Peter - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Post your server.xml file. I suspect the two Host entries have the same appBase setting, which is normally undesirable. Indeed they do. But both ROOT and OpenClinica are subdirectories of webapps.

Caldarale, Charles R wrote: Interesting. Where should such new appBase directories be? That's entirely up to you (and your sysadmin). So they don't have to be in and around the tomcat directories. OK, many thanks. I must have missed this in the docs: the plural status of the directory name webapps makes it sound as if you can have all your apps in there -- it's not apparent that that only applies when they are served from the same hostname. 3rd-party repackaged versions of Tomcat scatter files all over the place, so there's no standard (unlike a true Tomcat download from tomcat.apache.org). The only thing the RH version seems to do is put the configs in /etc amd change the install location to /var/lib/tomcat5. An unfortunate constraint of having to work on a machine maintained by a central facility. At least the internal structure is untampered-with. ///Peter - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

This is excellent and very helpful, thank you very much. I will digest this when I next get a slot. Yes, I also dislike running the RHEL repackaging, but in this case the system is maintained by the engineers on the basis that I do *not* add non-RHEL versions of things that are available in RHEL packages. Silly, but unavoidable. RHEL is hopelessly out of date in so many areas, and they have this compulsion to meddle which is very annoying. But in the case of Tomcat I have located all the bits and pieces, so it's not a major problem. ///Peter - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Yes.
I only get a short time per month to look at this stuff so my apologies
for not getting back sooner.
At the moment, all Cocoon pages get an extra cocoon/ token
inserted in their URI, eg http://myhost.server.domain/cocoon/stuff.
I did look at just replacing ROOT in webapps but that seems a
little heavy-handed,
Renaming a directory (or war file) is heavy-handed???
I would have thought so -- with an outsider's eyes. One doesn't normally
want to mess with the default directory layout of installed software,
only add to it and edit configs. I don't know what the default ROOT
actually does.
and it would seem to defeat any chance of adding Lucene and eXist.
No it wouldn't.
Excellent, thanks.
Look at the examples that come with the standard distro. It should be
apparent that (and how) multiple webapps are supported.

Unfortunately that is opaque to me. This is /var/lib/tomcat5 (under RHEL4):

Apart from cocoon, which I added, I am not aware of what balancer is or
what I might want it for. I can see examples, and tomcat-docs, and I
know what webdav is (although I don't use it). But these look to me like
utilities that come with Tomcat, rather than apps. No matter, if apps
they are, that's fine.

Aha.
You can obviously only have one default webapp per Host; other
webapps for the Host have to be explicitly named.
Yes, but where does this explicit naming take place? server.xml? web.xml?
I currently have a Host element type in server.xml naming the host
(which is a cname; this is all front-ended by Apache with a VH):
Host name=publish.ucc.ie appBase=webapps
unpackWARs=true autoDeploy=true
xmlValidation=false xmlNamespaceAware=false
!-- default application is Cocoon --
Context path= docBase=/var/www/xml/
debug=9 crossContext=true/
!-- anything with a slash is also the default --
Context path=/ docBase=/var/www/xml/
debug=9 crossContext=true/
...
This is currently all working and http://publish.ucc.ie is correctly
bringing up my Cocoon pages.
[me]
Is there another way to get rid of the cocoon/, because the
Cocoon pages will be the interface the user sees (but somehow
preserve an equivalent lucene/ and eXist/ because they won't be
seen much)?
Rename your Cocoon webapp to ROOT (remove the old ROOT first), and
install your Lucene and eXist applications under whatever names you
choose under the Host appBase directory.
Leave Lucene and eXist aside for the moment. I renamed ROOT to OLDROOT
and renamed the cocoon directory to ROOT. Restarted tomcat and apache.
But when I tried http://publish.ucc.ie I got a Tomcat 404
The requested resource (/cocoon) is not available.
Somewhere it's not looking in the right place. What other changes are
needed to make it pick up the app that is in the ROOT directory?
(I've renamed them all back the way they were for the moment.)
You likely only have one Host, and if you haven't changed the
default appBase setting, it's the webapps directory.
Exactly.
Your structure should look like this:
${CATALINA_BASE}
webapps
ROOT (containing your Cocoon webapp)
lucene (containing your Lucene webapp)
exist (containing your eXist webapp)
Yes, although lucene and exist aren't there yet, and there is the other
default stuff in webapps as shown in the listing above.)
The names are case-sensitive, so choose them carefully; they can be
anything you choose, other than ROOT.
I'm still trying to get it to serve cocoon when I move the default ROOT
out of the way and rename the cocoon directory to ROOT, but there is
obviously some other key piece of information I am missing here.

Running more than one application
I have been running Cocoon 2.1.11 successfully on its own for some time in Tomcat 5.5.23 under RHEL5 with Apache httpd 2.2.3 but I now need to add Lucene and some other apps. The cocoon.war was unwrapped in webapps, and the only installation mods I made were to add the virtual host block to Apache's httpd.conf VirtualHost *:80 DocumentRoot /var/www/xml ProxyPreserveHost On ProxyPass / ajp://localhost:8009/cocoon/ ProxyPassReverse / ajp://localhost:8009/cocoon/ ServerName my.server.name /VirtualHost and modified the sample Host element to match in server.xml Host name=my.server.name appBase=webapps unpackWARs=true autoDeploy=true xmlValidation=false xmlNamespaceAware=false Context path= docBase=/var/www/xml/ debug=9 crossContext=true/ Context path=/ docBase=/var/www/xml/ debug=9 crossContext=true/ ... (This may be suboptimal /var/www/xml/ is where my XML/XSLT files are, but it's unclear to me if this is actually needed at this level of the config.) This worked fine to test what I am doing in Cocoon, although the server sticks in an unwanted /cocoon/ into the URI. Now I need to add Lucene and several other apps (via .war files) but I am having difficulty understanding how to configure Tomcat to use multiple apps. As far as I understand it: a) I need to make Cocoon the default app, because that's what the bulk of the work will run through (but I'm happy to be told this is wrong). Comments in the mailing lists indicate that this will also get rid of the intrusive /cocoon in the URIs. b) I then add the other apps in servlet-mappings in web.xml I deleted the ROOT directory in webapps; renamed the cocoon directory to ROOT; removed the /cocoon from the httpd.conf; and added this to web.xml (and restarted tomcat5 and httpd) servlet-mapping servlet-nameCocoon/servlet-name url-pattern/*/url-pattern /servlet-mapping But accessing any URI using the virtual hostname then brought up the Tomcat 404 error requested resource (/what/ever) is not available. I have obviously misunderstood something vital here, but the docs don't seem to address this particular configuration, and my knowledge of Java isn't sufficient to dig into the innards of Tomcat. ///Peter - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
