Re: mod_jk session stickiness on failover

Now the JvmRouteBinderValve was designed to be used within a clustered environment I cannot see why it cannot be configured stand-alone to simply detect for an incorrect route and modify the client-side cookie appropriately. Because the first thing that that Valve does is to look if clustering or a persistent manager is configured and does nothing neither is the case. Hence my previous response. See the source code for details. Mark RGS SY On 5/18/2010 8:35 PM, JohnRiley wrote: Hi, We are load balancing 3 non-clustered tomcat 6.0 servers with the mod_jk connector in apache 2.0.

What happens then is that it start round-robin between the other two since none of them wants to accept the JSESSIONID with the route of the crashed tomcat server. How can I make one of the other servers to create a new session with its own jvmRoute for that tomcat? Because right now we have a huge problem when taking down a server for maintenance. The user will change server on each request until the server that is down for maintenance is back up again. Do we really have to setup the tomcats in a cluster to accomplish this?

Re: JAAS getRemoteUser security custom
Hi, I'm still not satisfied with the options so far and I'm sure I do not fully understand it: Although the valve works in that I can set the principal on the catalina request, realm.authenticate(username,credentials) within the valve is not actually passing anything to my JAAS login module although the login module is being used. Therefore, I can not currently authenticate the user within the JAAS module correctly as there appears to be no data passed from the valve. Also, if I use the valve then what is the point of the servlet using LoginContext.login()? If I choose not to use a valve then I appear to not have any access to the request object within JAAS. Even if I use org.apache.catalina.realm.JAASCallbackHandler, I do not get access to the request. So how are you able to add the principal to the request like you can do with the valve? SecurityFilter not an option as it does not support SSO. Thanks for the comments so far. Using a Valve will give you access to the the internal model of the request, so you can set Principals etc. I had the impression that a full JAAS implementation gave you access to the request and enabled the use of a Realm, but maybe it isn't what you need. The SecurityFilter project might be worth a look, before you commit to rolling your own. p - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
Re: Jmxproxy issue
From what I know, you do not get detailed memory information on the jmx proxy servlet without the JMX agent enabled. You can enable it by adding the following JVM argument. -Dcom.sun.management.jmxremote I have tested this on Tomcat 5.5.27 with Java 1.5.0_14. With the above JVM argument added to the Tomcat process you get detailed memory information including Garbage collections stats on the jmxproxy servlet. Hope this helps.

The above was not backported to 5.5 branch. Maybe there is some configuration that will allow seeing the above in 5.5, but I doubt that there is. Also check, what JRE versions your servers are using.

Prevent JSP Session
I am currently running Tomcat 6.0.24 on a Windows Vista machine. The web app I am developing will be deployed to a cloud, where server affinity will be thrown to the wind. Thus, instead of relying on tomcat to manage my session, I am instead managing the session via manual cookies and a database. Being that I cannot leverage the tomcat session, I don't want to create a session at all. This has a two-fold benefit: 1) Slight performance increase due to avoiding session creation overhead 2) I can put a session listener in place to log an error if ever a session is created, to ensure that we are not using the tomcat session in the development environment where everything would appear to be fine until we deploy to the cloud. According to JSP spec, I believe I should be able to use the following directive to prevent a session from being created by my JSPs: %@ page session=false %. However, even when doing so, I am still getting a session created by the internals of the JSP container. Is there something I am doing wrong? Is it possibly a bug in Tomcat 6.0.24 (couldn't find it on Bugzilla)? Or is it simply a necessary evil? The generated JSP code that is triggering the session is: pageContext = _jspxFactory.getPageContext(this, request, response, null, true, 8192, true); Below is the relevant portion of an exact stack trace: at org.apache.catalina.session.ManagerBase.createSession(ManagerBase.java:854) at org.apache.catalina.session.StandardManager.createSession(StandardManager.java:291) at org.apache.catalina.connector.Request.doGetSession(Request.java:2392) at org.apache.catalina.connector.Request.getSession(Request.java:2098) at org.apache.catalina.connector.RequestFacade.getSession(RequestFacade.java:833) at javax.servlet.http.HttpServletRequestWrapper.getSession(HttpServletRequestWrapper.java:216) at org.apache.catalina.core.ApplicationHttpRequest.getSession(ApplicationHttpRequest.java:544) at org.apache.catalina.core.ApplicationHttpRequest.getSession(ApplicationHttpRequest.java:493) at org.apache.jasper.runtime.PageContextImpl._initialize(PageContextImpl.java:146) at org.apache.jasper.runtime.PageContextImpl.initialize(PageContextImpl.java:124) at org.apache.jasper.runtime.JspFactoryImpl.internalGetPageContext(JspFactoryImpl.java:107) at org.apache.jasper.runtime.JspFactoryImpl.getPageContext(JspFactoryImpl.java:63) at org.apache.jsp.layouts.nav.layout_005fnav_002dadmin_jsp._jspService(layout_005fnav_002dadmin_jsp.java:44) at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:70) at javax.servlet.http.HttpServlet.service(HttpServlet.java:717) Thanks! -- Brett Birschbach HS2 Solutions, Inc brett.birschb...@hs2solutions.com

JMX requires use of additional ports that are normally dynamically allocated;
likely that your firewall is blocking them. If you're running on a current
version of Tomcat, look here to get around the problem:

Problem with IIS 7.0 plugin isapi_redirect on Windows 2008 64 bit
Hi I'm trying to configure the IIS 7.0 with latest isapi_redirect.dll (Ver 1.2.30) on Windows 2008 Server (64 bit). When I try to login to the Apache Tomcat 5.5 Servlet container, it fails with the error: 404 - File or directory not found. The resource you are looking for might have been removed, had its name changed, or is temporarily unavailable. Also I don't see any logs getting generated in isapi.log file, so I'm at a loss as to the root cause of this issue. I don't see isapi_redirect.dll getting loaded, however I notice isapi.dll being loaded. Attaching isapi_redirect.properties file below. Thanks in advance for your input. # The path to the ISAPI Redirector Extension, relative to the website # This must be in a virtual directory with execute privileges extension_uri=/jakarta/isapi_redirect.dll # Full path to the log file for the ISAPI Redirector log_file=c:\inetpub\scripts\isapi.log # Log level (debug, info, warn, error or trace) log_level=debug # Full path to the workers.properties file worker_file=c:\Inetpub\scripts\workers.properties # Full path to the uriworkermap.properties file worker_mount_file=c:\Inetpub\scripts\uriworkermap.properties rewrite_rule_file=c:\Inetpub\scripts\rewrites.properties Thanks Chandru Ganesan
clustering errors in 6.0.26 with multiple contexts
Hello, Since I'm running 6.0.26 I have clustering errors on startup of some contexts. I only see this on servers with multiple clustered contexts. I don't know if that is related. In 6.0.24 everything worked ok for months. Today I caught the stack below on startup after which I get a 60 second timeout on sessionreplication. Can this be anything which has changed in 6.0.26?

Re: Tomcat 6.0.20 unable to create new native thread
tom...@habmalnefrage.de wrote: cute domain name ;-) - all connections shown by netstat -an (not filtered): 4595 - connections in state close_wait: 3152 Due to problems with one of our webapps which sometimes does not close the threads completely (they stuck in close_wait-state) we increased the max threads of windows: So fix your webapp. I'll concentrate on that same one too. We have an issue on some systems, which may be similar. Sometimes the system becomes apparently incapable of responding to TCP connections at all, and we have linked this to a high number of connections in the same CLOSE_WAIT state. In our case, they are due to a webapp (of which we do not have the source), which allocates some kind of connection object which itself contains a socket. When the webapp terminates, it discards this connection object, but does not previously close() the socket. These objects then sit on the Heap until the next GC, and meanwhile they keep their socket in the CLOSE_WAIT state. When there are enough of them in that state, we start having severe problems on the system with other applications needing to connect to, or from, the system. (enough is a vague number ranging from hundreds to thousands, depending on the system). Triggering a GC of Tomcat solves the problem, immediately : the discarded objects get cleaned up, which frees the underlying sockets, and the CLOSE_WAIT list disappears, and the system is back to normal. I am not the great authority in those matters, but intuitively I would imagine that a socket is an OS-level structure, and that it uses some system resources, like RAM. And if you have thousands of them lying around, it may matter. The funny part about this, is that if you increase the Heap size, you actually make the matter worse : there will be more room for these discarded objects, delaying the time when a GC would occur. So you can accumulate a lot more of them, and freeze a lot more resources with them. To force a GC, one useful command line tool is available here : http://code.google.com/p/jmxsh/ - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

The startup.sh configuration is not broken. I didnt wipe out anything.
It is not firewall
Im using nmap and netstat to see the connecions open. I do not see the port
open in local, I do not see the port open, logically from remote.
The error in catalina.out comes up when I add the jxm options. Since it is
in Catalina.out I am asking if it is important..
Any more ideas?

Ranier - Thanks for the reply. I have some questions on your response. The

Sorry for the ignorance.

Can I get the same thing from the HttpServletRequest object by using the
getRemoteUser method when the request is made from IIS?
Any help here would be appreciated.
The source says: we forward GetServerVariable of REMOTE_USER to
Tomcat. in order to let Tomcat trust the forwarded auth data, you have
to set tomcatAuthentication=false as an attribute on the connector
element in server.xml.
Microsoft docs say: AUTH_USER:
The name of the user as it is derived from the authorization header sent
by the client, before the user name is mapped to a Windows account. This
variable is no different from REMOTE_USER. If you have an authentication
filter installed on your Web server that maps incoming users to
accounts, use LOGON_USER to view the mapped user name.

Re: mod_jk session stickiness on failover
Right on target. I noticed that it was the emptySessionPath=true that messed things up for me. When I removed it I got back to the wanted behavior. However, the emptySessionPath is needed since we are using mod_rewrite to change the url:s of the backend application. Otherwise we get a JSessionID with a /path rather than /. When I removed the emptySessionPath we got back a new cookie with the correct route. When I have it on I get no sessionId back at all. So the solution would be that the root-context and my application should have the same JSESSIONID (is it possible) or I can deploy my applicaiton in the root directory. /Johan Rainer Jung-3 wrote: On 18.05.2010 12:35, JohnRiley wrote: Hi, We are load balancing 3 non-clustered tomcat 6.0 servers with the mod_jk connector in apache 2.0.

The source says: we forward GetServerVariable of REMOTE_USER to
Tomcat. in order to let Tomcat trust the forwarded auth data, you have
to set tomcatAuthentication=false as an attribute on the connector
element in server.xml.
Microsoft docs say: AUTH_USER:
The name of the user as it is derived from the authorization header sent
by the client, before the user name is mapped to a Windows account. This
variable is no different from REMOTE_USER. If you have an authentication
filter installed on your Web server that maps incoming users to
accounts, use LOGON_USER to view the mapped user name.

Things just seems to stop working properly when I add emptySessionPath=true. Any idéas? Yes: emptySessionPath does two things: - it sets the cookie path to /, so that all contexts receive the same same session cookie - if a context gets a cookie and doesn't already have a session with the requested ID, it creates a new session with the requested ID. The second feature is where it fails for you, because now the jvmRoute is wrong. I would try working around using a servlet filter, but I'm not sure, how early in request processing emptySessionPath kicks in. There is a patch proposed for inclusion in TC 6 to make the session cookie path configurable. Not unlikely it will make it into 6.0.27.

Re: Question on workers.properties file
Ranier,
Thank you for the clarification.
As far as your instruction, let me ask the following if you don't mind:
What source are you referring to? Do you have a URL for this source?
Also, I've been trying to pickup this AUTH_USER from the
HttpServletRequest. Is that not where I can pick it up from? I thought I
could access it from the client request via the tomcat connector but I did
not know how to do that.
That is what I'm trying to get at to pass into my authentication method.
Again, any help/direction would be greatly appreciated.
Thanks again so much.

The web app I am developing will be deployed to a cloud, where server affinity will be thrown to the wind. Thus, instead of relying on tomcat to manage my session, I am instead managing the session via manual cookies and a database. Being that I cannot leverage the tomcat session, I don't want to create a session at all. This has a two-fold benefit: 1) Slight performance increase due to avoiding session creation overhead 2) I can put a session listener in place to log an error if ever a session is created, to ensure that we are not using the tomcat session in the development environment where everything would appear to be fine until we deploy to the cloud. According to JSP spec, I believe I should be able to use the following directive to prevent a session from being created by my JSPs: %@ page session=false %. However, even when doing so, I am still getting a session created by the internals of the JSP container. Is there something I am doing wrong? Is it possibly a bug in Tomcat 6.0.24 (couldn't find it on Bugzilla)? Or is it simply a necessary evil? The generated JSP code that is triggering the session is: pageContext = _jspxFactory.getPageContext(this, request, response, null, true, 8192, true); Below is the relevant portion of an exact stack trace: at org.apache.catalina.session.ManagerBase.createSession(ManagerBase.java:854) at org.apache.catalina.session.StandardManager.createSession(StandardManager.java:291) at org.apache.catalina.connector.Request.doGetSession(Request.java:2392) at org.apache.catalina.connector.Request.getSession(Request.java:2098) at org.apache.catalina.connector.RequestFacade.getSession(RequestFacade.java:833) at javax.servlet.http.HttpServletRequestWrapper.getSession(HttpServletRequestWrapper.java:216) at org.apache.catalina.core.ApplicationHttpRequest.getSession(ApplicationHttpRequest.java:544) at org.apache.catalina.core.ApplicationHttpRequest.getSession(ApplicationHttpRequest.java:493) at org.apache.jasper.runtime.PageContextImpl._initialize(PageContextImpl.java:146) at org.apache.jasper.runtime.PageContextImpl.initialize(PageContextImpl.java:124) at org.apache.jasper.runtime.JspFactoryImpl.internalGetPageContext(JspFactoryImpl.java:107) at org.apache.jasper.runtime.JspFactoryImpl.getPageContext(JspFactoryImpl.java:63) at org.apache.jsp.layouts.nav.layout_005fnav_002dadmin_jsp._jspService(layout_005fnav_002dadmin_jsp.java:44) at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:70) at javax.servlet.http.HttpServlet.service(HttpServlet.java:717) Thanks! -- Brett Birschbach HS2 Solutions, Inc brett.birschb...@hs2solutions.com - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

I tried to retrieve it using this class on the header Authorization but I am still getting a NULL value.

Keeping tomcat up-to-date on linux
Hi, The current release is 6.0.26, March 2010. RHEL5.x is running with Tomcat 5.5. Fedora 12 is on 6.0.20, June 2009 vintage. Ubuntu 10.04 is on 6.0.24 from Jan 2010. Ideally, the equivalent of a yum update would track tomcat releases so that soon after a tomcat release the tomcat6 package would move to the next minor release. Does this happen for any distro out there? What do people do to keep their tomcat patched up?

Presumably your method means you have to maintain your own init.d scripts and use the tar xzvf method of installation, outside of your distro package management system.

I don't recall ever having to change anything but the paths in the init.d script, but yes, I do use `tar xvfz` to install. Which means I can install in parallel to any other running instance(s) and test before cutting over. The inability to do that with any package managers I'm aware of, plus the release gap, is why I don't bother with them. Untarring a file just doesn't seem all that onerous to me.

RE: Keeping tomcat up-to-date on linux
Yes, the release gap is an issue for me as well. Hence this email trail :-) Parallelism is achieved for us for other software by package updating the test/dev server and testing that prior to performing the same updates on prod. There is no need for us to have two versions of tomcat running on the same host. So, if the package manager would just stay up-to-date with tomcat releases it would mean we wouldn't have to have special practices for Tomcat 6. I'm pleased to hear that the upgrade process is trivial with your setup. If you're going to have special practices, they might as well be simple. On what did you base your init.d scripts? And what is your underlying distro? We use redhat/fedora. Dale - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Since I don't use package management for anything important, it's not special practice :-) On what did you base your init.d scripts? Don't remember, actually; I've been using pretty much the same basic version for a long time. I mean, it's just a shell script, eh? And what is your underlying distro? We use redhat/fedora. As a consultant, whatever the client's running; my own dev desktop system is SuSE, my own production server is RHEL, and I've got a couple of different Linux VMs on my MBP for testing. That changes periodically. And of course I'm running multiple Tomcats on the Mac too :-) Which, now that I think of it, is a good reason to install from the tar file; it's the same everywhere. I don't have to use yum here, rpm there -- the same simple drill works *everywhere*. Obviously, your situation sounds quite different from mine :-) -- Hassan Schroeder hassan.schroe...@gmail.com twitter: @hassan - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
Re: Keeping tomcat up-to-date on linux
Exactly right, Hassan. I think it is extremely unwise to leave any critical portion of one's system--personal, development, or production--at the hands of the distro. I've used Linux for over a decade, and install Apache, Java, Tomcat, etc. by hand. ALWAYS. Oft times I build Apache myself.
