Hi, Caldarale, Charles R wrote: The problem I have is that occasionally after I restart Tomcat, the startup fails with NoClassDefFoundError or ClassNotFoundException for every servlet listener that's being added from web.xml. This kind of error can be caused by having the same class(es) in multiple locations in a given branch of the classloader tree, such as in both a webapp's WEB-INF/lib and in Tomcat's lib directory (or on the system classpath). Have you checked that? I removed the obvious suspect, a duplicate postgresql driver that appeared in both WEB-INF/lib and [tomcat install dir]/lib. Unfortunately this did not seem to help. Last night I needed to restart the production server for a configuration change and I needed 22(!) restarts for Tomcat to start up correctly.

Re: Occasional NoClassDefFoundError, but disappears after couple of restarts
A couple months ago I had a slightly different setting but with the same strange result - NoClassDefFoundErrors which occurred on a particular jsp page in my app, but only if it was the first jsp accessed following a restart (and remained in the error state until the next restart). If it was not the first jsp accessed, then everything came up fine (with nothing in the configuration or app changing in between). I also figured it's some classloader bug in Tomcat, not entirely a race condition (since it did happen consistently), but something that manifests itself depending on the order of class loading. I never did find out for sure what the problem was (maybe it's the sync issue Mark refers to below), but I stumbled upon a workaround, which I do not quite understand, which fixed this for good: I changed the order of the first two statements in the jsp, the first was one that accessed java.net.URI (a system class) and the second the session bean declaration (a custom app-specific class). Although the two statements were unrelated to each other and their order should not have made any difference, this solved the problem (switching them back did reintroduce the error, consistently). I still suspect the problem was with the order of classloading. So, not sure if this will help, but in the off chance that your issue is related to the one I was experiencing, you might want to try fiddling with the order in which classes are accessed/loaded by Tomcat (either via their xml reference, or their actual content's first statements) and hopefully something will work. Yes, it sounds strange, but it worked for me in a reproducible manner. Good luck :-) Amichai Mark Thomas wrote: M4N - Arjan Tijms wrote: I removed the obvious suspect, a duplicate postgresql driver that appeared in both WEB-INF/lib and [tomcat install dir]/lib.

virtual hosts for chrooted Tomcat
Hi all, I'm preparing for deploying Tomcat based web applications on a dedicated server (finally!). I have experience with Tomcat webapps on my local Windows machine, but am making myself familiar with a real-life situation on a Ubuntu Linux server. From what I've read, chrooting Tomcat seems a sensible security measure, documented in detail in O'Reilly's Tomcat: the Definitive Guide (http://oreilly.com/catalog/tomcat/chapter/ch06.pdf). Before I start messing around, however, I would like to clarify some concepts. If I 1. setup Tomcat for virtual hosts, serving webapps from another directory than %TOMCAT_HOME%/webapps, say /var/www/virtualhosts/[virtualhost]/ 2. install Tomcat in its chroot jail at /home/chroot/tomcat ...will Tomcat be able to serve these webapps? In other words: is it possible to have Tomcat serve web applications that are physically located outside the chroot jail within which Tomcat is running? I am considering this option because I would like to configure the webapps under /var/www/virtualhosts/[virtualhost]/ for chrooted SSH/SFTP access as well. If this is not possible, are there perhaps other common guidelines for configuring virtual hosts for a chrooted Tomcat? I'm aware of and apologise for the basic level of these questions; any hints would be really appreciated!

No, chrooting really does limit filesystem access to directories to within a specified directory tree. Whatever you want to access from a chrooted process must reside within that same chroot restriction. You might be able to set up chrooting so that Tomcat is able to access all virtual hosts, and so that each sftp/ssh update account only has access to the specific virtualhost directory tree, but for this case the Tomcat chroot point must be a common point above all the virtual hosts. So, if you f.ex. have a directory structure /a/b/tomcat /a/b/vhost1 /a/b/vhost2 ... then, if your Tomcat process is chrooted to /a/b/tomcat, it will not be able to access any directory which is not below the /a/b/tomcat directory. This is the whole and sole point of chrooting: the root directory accessible to a process is changed to something else than the real root directory of the underlying filesystem. Instead, if you chroot tomcat to /a/b, then it will be able to access anything wihtin /a/b, including all three abovementioned directories. Also, when you run a process chrooted, copies of all files needed by the process must exist within the chrooted environment (f.ex. all JDK files needed by Tomcat). Note though, that these (chrooting) questions have little or no relation with Tomcat as is, but would be more properly handled in an OS-related forum. -- ..Juha - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

RE: IP-based virtual hosting with Tomcat(6)
Uma - If you are really serious about using 1 SSL certificate for all your connections, you need to understand SSL much better than it appears you do at the moment. Some things to note: 1) The Common Name of the SSL *must* match the name the user gives in the hostname portion of the URL he enters in his browser, or else the browser will complain. It doesn't matter if the name is provided as an IP address or a normal string name. 2) The direness of the complaint is totally dependent on the browser and the version of said browser. 3) To have one certificate match multiple hostnames, you need a wildcard certificate, where the common name is like *.domain.name. Do tons of research before attempting. 4) Internet Explorer interprets wildcard names differently than other browsers, and the spec as far as I can tell. Where host.domain.name will match the above, host.sub.domain.name will not. IE is the only browser I've found that imposes this limitation. And I don't think you can do *.*.domain.name to get around it either. Try posting to an SSL group to find someone more knowledgeable.

Lisa D Beggs/AC/VCU wrote: I guess nobody is willing to help me any further on the below? Just because you're called Lisa then... Because, as Hassan mentioned, you already got all the answers. There are 2 ways to do what you want. And in both cases, your directory structure will change somewhat. That's how it is, no way around it. #1 consists of renaming the existing ROOT application to something else, and then rename your application to ROOT. This does not change the directory structure below whatever is the top directory of your application. It just changes the top directory name of your application. In other words, suppose you currently have (tomcat installation directory)/webapps/ROOT/* and (tomcat installation directory)/webapps/YourApp/* then ROOT should be renamed to XYZ, and then YourApp should be renamed to ROOT. That's it. Except that you should stop Tomcat before you do that, and restart Tomcat when it's done. #2 solution consists of using Virtual Hosts. You already have one, although you probably don't know that. It is represented by the single Host name=localhost... ... /Host section in your server.xml. The trick consists of creating a second one, very similar but with some attributes changed in it. But anyway, in that case, you will have to move your application, which is currently in (tomcat installation directory)/webapps/YourApp/* somewhere else.

after setting timeouts got puzzling results
Hi, We are running with apache loadbalancer and 19 tomcat workers loadbalanced. I went through the timeout document and other documents, and my apache access log in detail before choosing the timeout values. I am seeing a bit surprising results after setting timeouts. Earlier we did not have connect_timeout, prepost_timeout, reply_timeout, recovery_options and ping_mode set. After going through the documents and analyzing our application logs for timings I set the following values. ping_mode = A reply_timeout=6 recorvery_options=3 socket_connect_timeout=5000 Ping_timeout is set to the default value that is 1. I saw that one of the tomcat instances had out of memory errors and loadbalacer still showed that worker in good state for 24 hours. I felt after setting these timeouts infact it should have detected conditions like this quickly. What am I missing?

what exactly happens when timeouts are set and tomcat has outofmemory errors.
Hi, Can somebody go over the details of what exactly happens when tomcat instance has outOfmemory errors and there are following timeouts set in a loadbalancer worker config. This is my understanding. ping_mode=A, ping_timeout=1, reply_timeout=6 and recorver_options=3 If the timeouts are set as above then CPing/Cpong test for connect and prepost will work. When a new real request is sent to this tomcat instance, it should hit reply_timeout because it has outofmemory errors. Then depending on no. of retries set (it is default, for me so 2), this instance will be tried once again. Second time also it should not get reply within reply_timeout and at that point it should be marked in ERR state. However, I don't see that. I don't see it being marked in ERR state. The state is still OK inspite of this tomcat instance having outofmemory errors. Could somebody explain what am I missing? Also, what does recorvery option mean in this case? Is it possible to explain what happens when I set recovery options? what happens when I set it to 3? What will happen if I set it to 7? I am really hoping to get more understanding of how this works.

(At least I suppose it is mod_jk). - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Re: what exactly happens when timeouts are set and tomcat has outofmemory errors.
Before I set the timeouts thats how it worked. The tomcat instance in outof memory state would be eventually marked in ERR state. I thought by using timeouts it would set it to ERR state early. I do need to restart the tomcat instance in outofmemory error but how would I know tomcat instance is in that state unless I keep checking logs of all tomcat instances. I used the ERR indication on jkstatus page to know if there is something wrong with tomcat instance. Actually, before setting the following timeouts, I would see tomcat instances get marked to ERR state. After, setting these timeouts that is not happening as much as it happened before. After setting these timeouts I have got lot more error reports of website access errors. Do you know anything about recovery options?

how to get realm name
Hi, I want to digest the users credentials the same way as Digest authentication: RealmBase.Digest(username + : + somehowGetRealm() + : + password, MD5, UTF-8); I have been looking through the code and API, but cannot find a way to get the realm name to perform the digest.

You seem to think this is more difficult than it really is. Just follow the doc: uncomment the SingleSignOn valve in server.xml and you're done - it's that simple. No changes are required to webapp code. 2. is there any sample war that i can try out on this? Any set of webapps that have security constraints can be used. The standard manager and host-manager webapps that come with Tomcat both have security constraints specified in their web.xml files; you can add whatever constraints you want to whatever webapps you want. Read the servlet spec for details about security constraints. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

RE: how to get realm name
From: Robert Koberg [mailto:r...@koberg.com] Subject: how to get realm name I have been looking through the code and API, but cannot find a way to get the realm name to perform the digest. I can't find any direct mechanism either, if you don't want to use Tomcat internal classes. Here's a rather ugly method, but it might work. The web.xml for the webapp is accessible as a String via the JMX path: Catalina:WebModule://[host]/[appName]:none:none:Attributes:deploymentDescriptor Once retrieved, you could parse that for the login-config element. (You could also just read in the web.xml file, if running from an expanded war file.) It does seem odd that there's not a standard API to retrieve the login-config values, but I suppose that's because it's intended to be used only by container-managed authentication. Note that if you leave out the realm-name element, it defaults to [host]:[port], which is easily retrievable from the Request object via getServerName() and getServerPort(). - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

Log file rotation
Hi All, We are using Tomcat with IIS 6.0 with the the ISAPI redirector and I have realized that the log file is growing and growing. What I want to know how do I rotate the ISAPI log file ? Windows Registry values are like below log_file=d:\tomcat\logs\isapi.log log_level=debug Thanks, Vikram
