Subject: Using Tomcat over NFS over multiple hosts, want to separate
locations of directories
Hello folks
I am currently trying to convert from Resin Pro 3.0.17 to Tomcat 5.5. We
have several Solaris 9 machines and we generally place applications in a NFS
mounted /usr/dist/ directory, which is RO for the web application servers.
I have a local link, /usr/resin - /usr/dist/pkgs/resin
which points to /usr/dist/pkgs/resin/ - vers/resin-pro-3.0.17 so that I
can easily install a new version of resin by changing that link. I have my
RESIN_HOME=/usr/resin, which is the NFS mount and my
SERVER_ROOT=/usr/local/resin, which is a local directory. In my resin.conf,
I use
web-app-deploy path=/w/${mode}/warfiles
expand-path=/usr/local/resin/webapps/
to have Resin look on another NFS mounted directory /w for its warfiles,
which it expands in the locally mounted /usr/local/resin.
This setup allows me to have my resin config files, binaries, shared
libraries, etc, on a central NFS server, my warfiles on another NFS server
and the only thing I need to have local is the webapps dir where it explodes
the war files, and cache and session. I am thus able to turn a machine into
a resin server by copying over one rc file, which when invoked creates the
/usr/local/resin dir and pulls everything else it needs off of NFS.
I've been scouring the web for days trying to figure out how to make
Tomcat do the same thing, but can't for the life of me figure out how... the
two main problems I run into is the inability to separate the web app deploy
path, i.e. where it LOOKS for the warfiles and the expand path, where it
expands them. The other problem is wanting to put the conf/ files in a
different location from the webapp/ files. $CATALINA_BASE seems to be the
extent to which you can separate things, and it wants to put conf, logs,
shared, webapps. work. temp together...
So my question is how in Tomcat do I put the bin/ common/ conf/
server/ and shared/ directories in one location (NFS mounted RO) the temp/
webapps/ and work / locally ; logs/ (all of them, including catalina.out)
in a sepate location NOT in $CATALINA_BASE or HOME; AND put the location
Tomcat looks for new .war files in another NFS mounted location.
I know I could do it all with sym-links, but god that would be messy. Any
suggestions?

RE: Apache 2.0.50 - Tomcat 5.0.28 - Mod_jk - .htaccess
There are any form of change the loading order or i would need reinstall apache. Re-intalling will do you no good. You'd still end up with the same Apache. Re-building it, would, but that can be quite a task. Finding a newer version, differently compiled, might also be a good idea. Anyway, I'm not sure what is the loading order of modules, but it appears that staically linked modules load after dynamically built ins. And you have no control over mod_access.

Realm and Authentication with Tomcat 5.0, Apache 2 and mod_jk 1.2
Hi, We have a web application deployed under Tomcat 5.0 which uses a custom Realm for authentication. This custom Realm basically does a web service call using the user's credentials to authenticate with the web service server (basic WS-I username/password authentication). If the web service call fails (user not allowed to call the web service with his credentials), then Tomcat authentication fails. If the web service call succeed (user has access to the web service), then Tomcat authentication succeed and the Realm will store the Session object returned by the web service in a ThreadLocalContext to be reused later in the web application. This works fine with Tomcat only, but as soon as I add mod_jk and try to use Apache to do the authentication and then pass the credentials to Tomcat (using tomcatAuthentication=false), I get the 403 - access denied page. I'd like to know if, in my configuration (Apache authentication + Tomcat Realm + tomcatAuthentication=false), Apache is supposed to pass the user login/password to the Tomcat Realm or if the realm is not called at all (This would be the bad news I fear)? My combination Apache/Tomcat/mod_jk works when I specify tomcatAuthentication=true. But, I'd like to have Apache authentication and the Tomcat Realm called automatically after that with the username/password... Is this possible or do I have to move my Session creation process somewhere else?

Problem with Tomcat and Java versions
Hello everyone, I was using java 1.4.2 here, and recently migrated to java 1.5. Unfortunately, something probably is missing, 'cause I'm having problems with Tomcat. When I turn on the computer (that has tomcat on it), if I open the browser and try to access a web application built on java 1.5, it will give me the famous struts error: Cannot find ActionMappings or ActionFormBeans collection. However, if I open a web app built on java 1.4.2, everything works fine. Then, if I just restart the tomcat server (with the command /etc/init.d/tomcat 5 restart) and try to access the first application (the one built on java 1.5), everything will work fine. I'm guessing it's because there's maybe an environment variable that I may have forgotten to update or something. Here go my variables: JAVA_HOME = /usr/local/jdk1.5.0_06 PATH = /usr/sbin:/bin:/usr/bin:/sbin:/usr/X11R6/bin CLASSPATH is empty, my jar's are on the application's lib folder. Is there something else I should have setted? Is there something I gotta set in tomcat to show it what java version to use? I use Tomcat 5 and my server runs on a Suse Linux 9.3 box.

Re: Log4j configuration on a per context basis
This is trivial if you only introduce log4j.jar in each web app. If you share log4j.jar across web apps, then you have some LoggerRepositorySelector coding ahead of you. This is easy enough via JNDI context for cases where the contextual classloader is set for you by Tomcat, but in other cases (e.g. JMX remote request threads) you have to do such classloader setup yourself. Our web app now supports a per context log4j even if log4j.jar is shared -- in which case anything outside all the web apps goes into another log4j context. Note the log4j JMX MBeans don't support this sort of thing properly (they have a hard-wired ObjectName location for starters), so you'll have to write your own if you're interested in that aspect.

Re: Logging session timeouts
I was hoping for something a little simpler to implement into my app for
just logging a user timing out (something like a HttpSession.timeOut
event), but I will definitely have a use for the high water mark
functionality in the not-too-distant future.
Thanks!

FW: Catalina.out gets to big- Server crashes
We rotate the catalina.out file using the logrotate program on linux. The
rotation is based on file size - 10 Meg limit. We use copytruncate with
compression and maintain 14 rotated files before overwriting the oldest.
The following is a logrotate script that is placed in the /etc/logrotate.d
directory of the server running the tomcat app:
/home/tc1/tomcat/logs/catalina.out {
rotate 14
size 10M
copytruncate
compress
postrotate
# reset ownership to comply with directory's permissions
chown tc1.apps /home/tc1/tomcat/logs/catalina.out.*
endscript
notifempty
missingok
}
The man page on lograte is pretty thorough.

As far as I'm aware catalina.out can't be rotated. For the Tomcat
servers I maintain I've written a script that stops/moves
catalina.out/gzips catalina.out/starts Tomcat every Sunday night at
4am. Not the most elegant solution but it works.

;O) Yeah, this is missing in the documentation. I needed two hours to solve this whole problem. Hopefully you didn't waste so much time. You could also add this context.xml to a certain folder in Tomcat.

Re: Logging session timeouts
I got your code in, and it compiles, but I don't understand how I
configure the url-mapping you refer to. Could you point me to some docs
for that? I looked through the web.xml files (both the server one, and

Setting a classpath will not work as tomcat doesn't use it. At least that is what I have read and experienced. putting you stuff in the CLASSPATH tomcat uses is a more likely scenario.

Cool; I'll give that one a try as well. Do you have any idea which one
is likely to give less of a performance hit in an environment of 50 to
100 simultaneous users, where everything is done in a session, and there
is no static content?

While the user can delete the cookie that is associated with the session, the server will consider the session valid until it times out, as the user is unable to end the session manually.

RE: Logging session timeouts
The filter, implementing HttpSessionListener, and binding itself to the session, will be called by Tomcat when the session is invalidated (all bound values which implement HttpSessionListener will have their valueUnbound method called.) So, the filter is effective in that it won't miss any session unbind events as long as the filter captures the creation request as well. If you create the session but the request which does so has not passed through the filter, then it will not know when the session goes away. So in the listener case, you are guaranteed a call from the server any time any session is created. That might be a better approach, depending on your need(s). In my case, the filter does a whole lot more, but I stripped it down before posting it to only show the relevant section.

RE: Logging session timeouts
The listener should get called only once, right? Whereas the filter will get called for every matching URL (keeping in mind it does additional useful things in my case...) and if checks to see if the session is new each and every time. I seem to recall an issue recently (can't find it in a quick scan of the archives) about sessionDestroyed(SessionEvent) being called after the session is invalidated. I think the valueUnbound() method gets called during the destruction process and the session is still valid at this point. DON'T QUOTE ME ON THIS! I wrote the filter a while ago, and have just brought it along as needed... If someone knows for sure... Please let me (us) know.

So in the listener case, you are guaranteed a call from the server any time any session is created. That might be a better approach, depending on your need(s). In my case, the filter does a whole lot more, but I stripped it down before posting it to only show the relevant section.

RE: Logging session timeouts
Well let's just think about that for a second. Filter: a filter is called each and every time you make a web request. So even if the filter is highly efficient, if you make 1000 requests in a session, you (that is, the container) will invoke the filter's doFilter method 1000 times.

httpd, tomcat, mod_jk and LAST_MODIFIED
Hello all, I'm having a problem with a couple of my servers, whereby the last modified date of an shtml file isn't being properly reported by the LAST_MODIFIED variable, if server side includes are used in a directory that is served by mod_jk / tomcat. So, to break down the run-on sentance... I have servers, running httpd 2.0.55, tomcat 4.1.31, and mod_jk from tomcat_connectors 1.2.15. I have several users that use the following code to report back the last modified date on their pages, using server-side includes: !--#echo var=LAST_MODIFIED-- If I use server side includes on a page that is served by httpd, outside of a tomcat context, I get the proper response, i.e. the last modified date. Here's an example: http://edjo.usask.ca/test.shtml If I have the same page in a tomcat context, the last modified date is reported as Wednesday, 31-Dec-1969 18:00:00 CST which I believe is the UNIX epoch. This suggests that it's just getting '0' when it reads the last modified date. Here's a corresponding example: http://edjo.usask.ca/classes/test.shtml All other variables report properly. I've hunted through the mailing list archives here with no luck, posted in other forums with no useful response, and Google hasn't been of any help at all. I'm hoping that SOMEBODY has seen this problem, and has a workaround / fix. On the example pages I've posted above, I've included information on my setup - my server software and the included modules. I can also post appropriate configuration files if necessary.

Thanks! It seems to be unanimous then, that for the purposes I need, the listener is the way to go.

Re: Calling Realm.authenticate() doesn't register Principal in with the Session??
I'm trying to re-word these two concepts in a more elegant way:
1) I'm looking for a way to use form based authentication - but unlike
with the current form login Realm, I need a way to intercept the persons
email address(s) (typed into the username field), so that I can convert
that into its corresponding username *before* passing it to the Realm
(this cannot be done with the current form based login).
For this method, I would *prefer* not to write an override to any
existing Realm (Form or WWW-Authenticate) - because users may already
have their own. In other words, I would like to be able to call into
whatever Realm the user already has configured (provided it's a
user/pass one).
2) As an alternative, being able to simply register a given username
(void doLogin(Principal p)) with a session via the server API would also
be very useful - one could perform their own password or X509 validation
inside of a servlet/jsp (using rules that are much more strict than what
the current impls support, e.g trust levels/rules for issuers, and
revocation checks, and critical subject flags for x509 certs). One could
also implement the simplest possible (yet highly customizable) login
logic against say, a database:
ResultSet rs = ps.exec(SELECT pass FROM auth WHERE user = ?
,request.getParameter(user));
if (Digest.sha1(request.getParameter(pass))
.equals(rs.getString(pwdSha))
)
Tomcat5.doLogin(session, new Principal(request.getParameter(user));
I hope that these two (very different) concepts will be tantalizing
enough that some highly simplified auth APIs/concepts will make their
way into the server. I have tried to build the first one - but the
protected request/response fields in CoyoteRequestFacade cannot be
accessed from a external class, and reflection would be needed to
cast/call the method. An 'expert' will do much better than I.

Re: Realm and Authentication with Tomcat 5.0, Apache 2 and mod_jk 1.2
Mickael Goujon [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] Hi, We have a web application deployed under Tomcat 5.0 which uses a custom Realm for authentication. This custom Realm basically does a web service call using the user's credentials to authenticate with the web service server (basic WS-I username/password authentication). If the web service call fails (user not allowed to call the web service with his credentials), then Tomcat authentication fails. If the web service call succeed (user has access to the web service), then Tomcat authentication succeed and the Realm will store the Session object returned by the web service in a ThreadLocalContext to be reused later in the web application. This works fine with Tomcat only, but as soon as I add mod_jk and try to use Apache to do the authentication and then pass the credentials to Tomcat (using tomcatAuthentication=false), I get the 403 - access denied page. I'd like to know if, in my configuration (Apache authentication + Tomcat Realm + tomcatAuthentication=false), Apache is supposed to pass the user login/password to the Tomcat Realm or if the realm is not called at all (This would be the bad news I fear)? Sorry for the bad news, but the Tomcat Realm is not called at all in this situation. Also, Apache doesn't forward the password directly (although it is still in encoded in the Header). My combination Apache/Tomcat/mod_jk works when I specify tomcatAuthentication=true. But, I'd like to have Apache authentication and the Tomcat Realm called automatically after that with the username/password... Is this possible or do I have to move my Session creation process somewhere else? A custom Authenticator is probably over-kill here. I would probably just use a custom Valve. But as-is, you do at least have to add something (or, modify your copy of the Tomcat code :) to invoke the Realm.

Re: Using Tomcat over NFS over multiple hosts, want to separate locations of directories
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 I think I have it, well, at least part of it... using the argument - config $CATALINA_HOME/conf/server.xml allows it to start up, but then if the CATALINA_BASE doesn't have a conf/ directory, it doesn't work. I copied the conf directory from the $CATALINA_HOME directory and got it to start up. I can't for the life of me find anywhere that you can tell tomcat that it should look for it's whole [EMAIL PROTECTED]@ conf/ directory in $CATALINA_HOME NOT $CATALINA_BASE cause wouldn't it be convenient to have ONE conf/ directory mounted for multiple servers on one NFS mount. Yes, NFS is satan, etc etc... but it's what I've got to work with. Mark Demma Senior UNIX Systems Admin PlanetOut Inc.

It might be worth a try as some of your paths may appear as links to Tomcat even if they are mounted volumes.

RE: Using Tomcat over NFS over multiple hosts, want to separate locations of directories

I don't think that was the intent of CATALINA_BASE, which appears to have been designed to allow multiple instances of Tomcat _on_one_system_ to execute from a single installation. Since each such instance requires a separate conf/server.xml to define the ports, IP addresses, etc., that has to go under CATALINA_BASE, not CATALINA_HOME (which is pretty much just for code). - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

Tomcat Security Vulnerabilities
Hi. Just wanting to know if anyone can tell me in which version of Tomcat the bug was fixed that allows you to enter in a URL like http://domain.com/%3f.jsp and get a directory listing. I know it exists in 3.2, just wondering which version it was fixed in. Thanks, Jo. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Problem with Tomcat and Java versions
Do you have the option of reinstalling Tomcat5 - so that Tomcat5 would just pick up java 5 and not have anything at all to do with java 1.4?? -Anoop On 2/9/06, Letícia Álvares Barbalho [EMAIL PROTECTED] wrote: Hey, First of all thank you very much for the attention. I got some reading about it and found the jars [jaxp_parser_impl].jar and [xml-commons-apis].jar under /usr/share/tomcat5/common/endorsed I renamed them (so they could not be found) and restarted the server (the computer, I mean).

Unfortunately, something probably is missing, 'cause I'm having problems with Tomcat. You don't say what Tomcat version you're using. If you were running 5.5.xon JRE 1.4.2, there may in fact be something extra, not something missing. The compatibility package that's required for 1.4.2 execution should be removed when using JRE 5; the package consists of two jars in common/endorsed, and these should be deleted. Of course, this may or may not have anything to do with your problem, but it's something to try. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

tomcat + certificate
Hi, I am running a tomcat server running here. We have a servlet container hosted in the server. The servlet is called from a java client program and is working fine(http). Then i following the instructions from the tomcat documentation page i installed a self signed certificate. The site now shows up with the certificate from the browser. The problem is while running the java client and connecting to the server(https) the program gives out error(connection timed out/SSL handshake ... etc). Hope i am not raising a dumb question here. What is wrong with my setup? Any pointers. Some one said we have to install apache also. Is that so? Is it possible to make tomcat handle the certificates itself and free the servlet from that. BTW, i am running on FC4, with tomcat version 5.5.12. TIA, SK - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
