A question about mod_jk 1.2.28 configuration
I newly installed the mod_jk 1.2.28 and since then got problem (see below). ** We have a web application deployed on Jboss (RH Linux OS). The access to the web application is via a Apache Httpd Web Server. One of the function of this web application is one can online generate PDF-reports. This report could by quite big (30 MB). After the report is generated (this will take about 20 to 40 min.) it will show up on the browser. Formerly we have mod_jk 1.2.26 and everything is ok. Since a week we update the mod_jk to 1.2.28 and got problem. Exactly to say, the PDF-report can not be shown up on browser. One can find some error messages in mod_jk.log as follow: Code: [Tue Nov 03 11:03:07 2009] [12138:2537062720] [info] ajp_connection_tcp_get_message::jk_ajp_common.c (1150): (worker_portfolio_son1) can't receive the response header message from tomcat, network problems or tomcat (172.23.17.37:8009) is down (errno=11) [Tue Nov 03 11:03:07 2009] [12138:2537062720] [error] ajp_get_reply::jk_ajp_common.c (1962): (worker_portfolio_son1) Tomcat is down or refused connection.

Re: errno 110 in mod_jk
On 09.11.2009 03:13, Mohit Anchlia wrote: Thanks. Looks like we are hitting the same bug. I am still looking for an answer to one of my questions that I posted earlier. To narrow down I just left one node running and started the test. When I look at JkStatus worker I see that even though all other nodes are down it's still showing OK in the status for those workers. I am not sure why it would do that. I expect it to show the workers in ERR status. No, there are two statuses: activation and state. If you down a worker via activation, its activation will be displayed either as disabled or stopped according to your config, but its runtime status is OK (i.e. there is no error, because you put it out of order administratively). It should be shown as OK/IDLE, i.e. we expect it to work, but it hasn't been used for a long time, so we can't be sure. status ERR is only shown, if a request detected the backend is not working. Do you know the default timeout of connectionTimeout? I am getting conflicting results. Some place it says 6 and other places 60. Is there any disadvantage of setting this value too low? Default: no timeout. Setting too low: the lower you set it, the more often connections will be closed an later reopened. It is a question of how long a connection should be reused. For server to server you want that to be typically 1 minute. Why not resuing for a very long time, e.g. unlimited? Because in case there is a firewall in between httpd and Tomcat it might drop idle connections. Also you might want to free connections (and thus threads) which were only necessary due to peak load or failover. I usually suggest something between 1 and 10 minutes.

Deploying and building a war file
Hi all, I've got a query on the way web applications are deployed. I have an application that has several jsp files and serlvets that are in WEB-INF/classes. When i deploy the application all i do is do a checkout on CVS, make the changes, rebuild the war using ANT and redeploy manually. This works fine but now i am having some doubts on this approach. Basicaly if i even change one file i have to rebuild the war file meaning i have to recompile everything. I think this is unecessary. i would like to be able to just recompile the one file and redeploy the one file without having to rebuild the whole war file. 1. How do you deploy your application? If you deploy as a war file, do you recompile everything even if the change is to a single file or a configuration file. 2. Could you provide an example on the approach you use from the point a source file comes out from CVS to the point it get to the production environment. (An example with a single file change would be usefull) 2. Do you use any tool to manage this? I am thinking that if i change one file i should be able to just compile that one file and move it to the WEB-INF/classes folder into the relevant folder. This might work but is there a better way of doing this instead of moving it manually? Thanks

Date: Mon, 9 Nov 2009 12:04:12 + Subject: Deploying and building a war file From: zigg...@gmail.com To: users@tomcat.apache.org Hi all, I've got a query on the way web applications are deployed. I have an application that has several jsp files and serlvets that are in WEB-INF/classes. When i deploy the application all i do is do a checkout on CVS, make the changes, rebuild the war using ANT and redeploy manually. This works fine but now i am having some doubts on this approach. Basicaly if i even change one file i have to rebuild the war file meaning i have to recompile everything. I think this is unecessary. i would like to be able to just recompile the one file and redeploy the one file without having to rebuild the whole war file. 1. How do you deploy your application? If you deploy as a war file, do you recompile everything even if the change is to a single file or a configuration file. 2. Could you provide an example on the approach you use from the point a source file comes out from CVS to the point it get to the production environment. (An example with a single file change would be usefull) 2. Do you use any tool to manage this? I am thinking that if i change one file i should be able to just compile that one file and move it to the WEB-INF/classes folder into the relevant folder. This might work but is there a better way of doing this instead of moving it manually?

Nagios3 and Tomcat6 configuration under Apache2.2

I'd like to monitor the system and so I want to use nagios3 but I don't know how configure VirtualHosts for Tomcat and Nagios under Apache ( I use Ubuntu so I have /etc/apache2/ports.conf and /etc/apache2/sites-enabled/000-default).

[SECURITY] CVE-2009-3548 Apache Tomcat Windows Installer insecure default administrative password
CVE-2009-3548: Apache Tomcat Windows Installer insecure default administrative password Severity: Low Vendor: The Apache Software Foundation Versions Affected: Tomcat 5.5.0 to 5.5.28 Tomcat 6.0.0 to 6.0.20 The unsupported Tomcat 3.x, 4.0.x, 4.1.x and 5.0.x versions may be also affected. Description: The Windows installer defaults to a blank password for the administrative user. If this is not changed during the install process, then by default a user is created with the name admin, roles admin and manager and a blank password. Mitigation: Users of all Tomcat versions may mitigate this issue by one of the following methods: - Using the .zip or .tar.gz distributions - Specifying a strong password for the admin user when using the Windows installer - Removing the admin user from the tomcat-users.xml file after the Windows installer has completed - Editing the tomcat-users.xml file to provide the admin user with a strong password after the Windows installer has completed A patch for this issue [1] has been applied to trunk and will be included in the next releases of 6.0.x and 5.5.x Credit: This issue was reported directly [2] to the tomcat users public mailing list by David Horheim. Security researchers are reminded that undisclosed vulnerabilities in Apache Tomcat should, in the first instance, be reported to the private security mailing list. [3] References: [1] http://svn.apache.org/viewvc?view=revisionrevision=834047 [2] http://markmail.org/thread/wfu4nff5chvkb6xp [3] http://tomcat.apache.org/security.html Mark Thomas - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Tim Funk wrote: Confirmed. The docs are not in sync with what the installer does. We'll get this fixed in a future release. In future, please report possible security issues privately rather than publicly. -Tim To complete the thread, this was announced as CVE-2009-3548. Mark David Norheim wrote: Hi, I would like someone's opinion on the following issue that we have discovered using the windows distribution of Tomcat 6. (tested for Tomcat 6.0.14, 6.0.16 and 6.0.20 downloaded from [1] ) The documentation for Tomcat 6 states It would be quite unsafe to ship Tomcat with default settings that allowed anyone on the Internet to execute the Manager application on your server. Therefore, the Manager application is shipped with the requirement that anyone who attempts to use it must authenticate themselves, using a username and password that have the role manager associated with them. Further, there is no username in the default users file ($CATALINA_BASE/conf/tomcat-users.xml) that is assigned this role. Therefore, access to the Manager application is completely disabled by default. While installing the zip or tar.gz version of the binary distributions does not open for the manager application, the windows exe version does. Having downloaded the exe version and started the wizard you get to screen where you are asked to enter Administrator Login username and password. The default settings leaves you with a tomcat-users.xml file that has the manager application enabled. Also there are (as far as I can see) no way to avoid this step in the installation wizard. The net result is that you end up with an unsafe installation, having this statement in the tomcat-users.xml file user name=admin password= roles=admin,manager / This is as far as I can see related to some of the problems that has occurred in the past, notably [2] and we also had a situation related to this in our installation. As far as I can see there is nothing wrong with the distribution file itself - it seems to be valid in relation to the md5 file so this must have been a design choice. Could someone please comment on this, and if there are any planned actions related to this. - 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

[SECURITY] CVE-2009-3555 SSL Man-In-The-Middle attack
-BEGIN PGP SIGNED MESSAGE- Hash: SHA512 A vulnerability in the TLS protocol has recently been made public [1] that allows an attacker to inject arbitrary requests into an TLS stream. The current understanding of the Tomcat developers is as follows: BIO NIO connectors using JSSE These connectors are vulnerable when renegotiation is triggered by the client or the server. Server initiated re-negotiation can be limited by configuration Server initiated re-negotiation could be prevented by a code change Client initiated re-negotiation can not currently be prevented APR/Native connector using OpenSSL Vulnerable when renegotiation is triggered by the client or the server. Server initiated re-negotiation is not supported prior to 1.1.17 Client initiated re-negotiation is supported but can not be prevented OpenSSL 0.9.8l disables all negotiation by default In terms of what this means for users: BIO/NIO - - We haven't yet (we are still looking) found a way to stop client initiated renegotiation. It may be necessary to wait for the JVM vendors to respond. APR/native - - Re-building any version of the APR/native connector with OpenSSL 0.9.8l will protect against this vulnerability but any configurations that require renegotiation will break. - - Version 1.1.17 of the APR/native connector will be released shortly. The binary versions will be built with OpenSSL 0.9.8l which will protect against this vulnerability but configurations that require renegotiation will break. Supporting renegotiation whilst avoiding the vulnerability requires a protocol fix. The Tomcat development team is examining possible work-arounds that may provide an interim solution. These options include porting r833582 from httpd to the APR/native connector which would disable client triggered renegotiation for OpenSSL 0.9.8l which may help some users who can't easily change their OpenSSL version. If you'd would like to join/follow the work-around discussions, please join the Tomcat dev mailing list. Any significant developments in this area will be posted to the Tomcat announce@ and users@ mailing lists.

Identifying Clients via SSL Certificates
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 All, I've been playing around with client SSL certificates, not for authentication per se, but as a gateway to a relaxed authentication mechanism for one of our webapps. I have a client SSL cert working (see my previous thread mod_jk Client SSL Certificates) and successfully verifying the signature of the client cert by the server. I'd like to be able to uniquely identify the client certificate being used to authenticate via SSL, but I'm a newbie at this sort of thing and I'd appreciate some suggestions as to how to do that. A few ideas I've had are: 1. Use a directory-style 'CN' attribute like UID=myuniqueid 2. Use the fingerprint of the client certificate 3.

Re: Deploying and building a war file
If you use Eclipse (www.eclipse.org/ free; runs on Wins/Mac/Linux) with the web plugins, it records your deploy target, and allows you to deploy with either a war file, or in exploded form. In the latter case, you can usually leave your web server running, make a code change, save the file, and it is automatically re-compiled re- deployed to the running server. At worst, you only need to hit a refresh button. It makes life much simpler, and the syntax-directed editor saves me from many stupidities. --Ken On Nov 9, 2009, at 7:04 AM, Ziggy wrote: Hi all, I've got a query on the way web applications are deployed.

Re: Want to customise the tomcat's session logic
Ok, i think i see what you mean. As far as I know there is no quickwin for that. Web application suffer with this disease - that mean sharing session over tabs. You have got three choices to deal with that. A) You dont mind :) B) You will prevent to work in multitabs over one session C) You choose the third and the hardest - to support it :) Here are some ideas, but no of them is 100% 1) set tomcat to use URL rewriting indtead of cookies (http://tomcat.apache.org/tomcat-6.0-doc/config/context.html) 2) produce some tab/browser identification and divide session (maybe window.name property could be helpfull) 3) Look at JBoss Seam, it also support multitab browsing without harming session as i know. Good luck ;) 2009/11/7 S Arvind arvindw...@gmail.com: To my knowledge, there is no path attribute in the session. Are you proposing that you add one? deploy one app in tomcat by having context xml in catalinadomainxxx.xml . When you access this app check the session u will find the path attribute with xxx in it. So... do you mean that you want to deploy one web application (into a single context), but you want to separate certain parts of the session into different areas of the webapp? yes I don't believe that deploying the same webapp multiple times into different contexts has any effect on session sharing: Tomcat will treat them as different webapps and no session sharing will occur unless you have taken other steps to share sessions between contexts. Session sharing will not occur for different context. But i need to have single context still session should not be shared. Is it possible in single context.?? Consider i have one login app, after login i track the state by session. First i login that website in single tab in browser and session was created with details in it. And in another tab or window i need to login with different username without sharing the session. But if i did this first created session was overwrite by second session.

WebappClassLoader and undeploy
I originally started down this path trying to find a memory leak (involving commons-logging etc). I now have a more general question: I've created an almost empty context. It contains 1 servlet which contains an arraylist (just to create a large object that is easier to see in memory graphs) and a default jsp page (as created by the maven webapp archetype). I deploy this along with the tomcat manager into tomcat 5.5.28, which is the standard tar.gz download with all the extra webapps stripped out of server/webapps (except for manager) and webapps. This means that there are 2 WebappClassLoader instances in memory, one for each context. This seems correct. There are also 2 WebappLoader instances in memory, I assume one for each context which also seems correct. Now my understanding of the WebappClassLoader is that there is and instance for each context and eacg class loader is used to load classes for that context. This allows for dynamic class loading and some (?) isolation for each context. My assumption (partially from what I have read) is that when the context is undeployed tomcat severs its references to the class loader and thus the gc process can clean up all the leftovers... Is this incorrect? I've deployed the very minimal context into tomcat and then undeployed it via the manager. I used VisualVM to look and the heapdumps from before and after. From the before heapdump I saw what I expected: 2 WebappClassLoaders and 2 WebappLoaders. After I saw: 2 WebappClassLoaders and 1 WebappLoader, which is not what I expected. Tomact seems to have retained 1 on the WebappClassLoader instances. I have two questions at this point: 1. From the Javadocs both WebappClassLoader and WebappLoader are class loaders. What are the differences and why does Tomcat use both? 2. Why would Tomcat be cleaning up the WebappLoader instance everytime successfully but seems to 'hang-on' to the WebappClassLoader instance?

Secure login only, not rest of app
Hi all, I am trying to have setup my tomcat webapp to be secure for login only. It works as you'd expect if the security-constraint for /* is unsecure and if I make it secure (using CONFIDENTIAL) for /*. However if I try to make it secure only for the login page and unsecure elsewhere any attempt to go to a page redirects to the login page but unsecure - not using the https and higher port.

I have a working https Connector because I can use the service configured for /* to be secure. Any offered help appreciated.

Re: WebappClassLoader and undeploy
Managing class loaders is done in the JVM. Tomcat cannot force the JVM to garbage collect class loaders, in the same way that it cannot force the JVM to garbage collect any object. If the class loader is unreachable, and all other objects that this class loader provided are also unreachable, then the JVM can garbage collect it like any other object. This garbage collection is heavier than simple object reference. I assume the JVM will do it only in major garbage collections and maybe even not in every major one. If your test app is not doing anything, there is no reason for the JVM to actually do something about it since memory is not consumed. If you try to force major garbage collections, eventually it should happen. If you run a load test, which will force tomcat to consume memory, then you will eventually get to a major garbage collection. This can take much longer than what you would think. If the code is simple (like JSP page and hello world type of servlet) it can be optimized by the JVM to consume memory on a local stack based heap (per thread), and not use the JVM main heaps. If you keep a reference to one object that was created from this class loader, then the Class object of this object is reachable, and the class loader is reachable via the Class. Since it is reachable, it cannot be garbage collected. WebappLoader is a class that has the code to manage a webapp lifecycle. It is not a class loader. The JVM to track references to it like any other simple object (String). In addition, it is an internal tomcat object, so it is a lot simpler to keep track of references to it in the tomcat code. It is not visible to the webapps or exposed to user code that can leak it. WebappClassLoader is the opposite: It is a real class loader. Garbage collecting it is not a simple matter. My guess is that: 1. If you constantly load the memory, then eventually it will be garbage collected. 2. If it is not garbage collected in that case, there is a reference leak, something is keeping a reference to either the class loader or to an object that was loaded by from it. Tomcat is releasing references to objects on its side, but the user code can do other things. If the web app contains one servlet and one JSP page, that should be easy to follow. Tomcat keeps references to those objects (both should be servlets), but also releases them when you redeploy. You can verify that the objects are gone. The actual instances should be gone very quickly since they are simple objects. JSP page is turned into a class, you should see it in the memory management tool. Notice that if the web app is reloaded, the new class loader will load the same classes again, so they will have the same class name, but they will have separate Class instances. You will have two objects that have the same class name, but are different class.

I have a working https Connector because I can use the service configured for /* to be secure. So, to summarise, you want *only* the login page to be sent over SSL? The login page isn't ever requested directly, it's forwarded to by the AuthenticationValve. This means that you can place it out of the way, in, say: WEB-INF/login/form.jsp WEB-INF/login/error.jsp but it also means that you shouldn't directly request the login page. When you're using Container managed security, you request a secured resource and the Valve forwards to the form. Once you authenticate the original request is restored. Your config won't enforce SSL for the login page because the container forwards the request to the page after it recognises the /* rule requires a login. If you want the whole app to require a login, you can either choose to use SSL, or not, but you can't easily send the login page only over SSL. If only one part of the app required a login, you could employ a Filter to downgrade to non-SSL when the URL didn't match that path. Is there a particular reason why you want to downgrade after login? You might look into the Tomcat compatible SecurityFilter project, as it provides very similar functionality to container managed security, but more flexibility. http://securityfilter.sourceforge.net/ p Any offered help appreciated.

Gerwood From: Elli Albek [e...@sustainlane.com] Sent: Tuesday, 10 November 2009 9:52 AM To: Tomcat Users List Subject: Re: WebappClassLoader and undeploy Managing class loaders is done in the JVM. Tomcat cannot force the JVM to garbage collect class loaders, in the same way that it cannot force the JVM to garbage collect any object. If the class loader is unreachable, and all other objects that this class loader provided are also unreachable, then the JVM can garbage collect it like any other object. This garbage collection is heavier than simple object reference. I assume the JVM will do it only in major garbage collections and maybe even not in every major one. If your test app is not doing anything, there is no reason for the JVM to actually do something about it since memory is not consumed. If you try to force major garbage collections, eventually it should happen. If you run a load test, which will force tomcat to consume memory, then you will eventually get to a major garbage collection. This can take much longer than what you would think. If the code is simple (like JSP page and hello world type of servlet) it can be optimized by the JVM to consume memory on a local stack based heap (per thread), and not use the JVM main heaps. If you keep a reference to one object that was created from this class loader, then the Class object of this object is reachable, and the class loader is reachable via the Class. Since it is reachable, it cannot be garbage collected. WebappLoader is a class that has the code to manage a webapp lifecycle. It is not a class loader. The JVM to track references to it like any other simple object (String). In addition, it is an internal tomcat object, so it is a lot simpler to keep track of references to it in the tomcat code. It is not visible to the webapps or exposed to user code that can leak it. WebappClassLoader is the opposite: It is a real class loader. Garbage collecting it is not a simple matter. My guess is that: 1. If you constantly load the memory, then eventually it will be garbage collected. 2. If it is not garbage collected in that case, there is a reference leak, something is keeping a reference to either the class loader or to an object that was loaded by from it. Tomcat is releasing references to objects on its side, but the user code can do other things. If the web app contains one servlet and one JSP page, that should be easy to follow. Tomcat keeps references to those objects (both should be servlets), but also releases them when you redeploy. You can verify that the objects are gone. The actual instances should be gone very quickly since they are simple objects. JSP page is turned into a class, you should see it in the memory management tool. Notice that if the web app is reloaded, the new class loader will load the same classes again, so they will have the same class name, but they will have separate Class instances. You will have two objects that have the same class name, but are different class. Other possible reference leaks from the webapp to the outside: Threads that are left running JNDI Sessions Thread local Any library in a class loader above the webapp (in class loaders app, system, common and shared, possibly even in Catalina but less likely) Logging and reflection libraries always star as favorite leakers. - 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
