Proxy timeout error in Apache error log
Hi all We have three Tomcat sites running on three different Tomcat instances on a server (let's call it myserverA). One of the sites runs on Tomcat 5.5 and two run on different instances of Tomcat 6. We then have Apache 2.2 running on myserverB and we use mod_proxy_http as the connector. We are regularly getting errors like the two lines below in our Apache log file on all three sites; (70007)The timeout specified has expired: proxy: error reading status line from remote server myserverA.com, referer: http://www.site.com proxy: Error reading from remote server returned by /cache/Folder/image.jpg, referer: http://www.site.com Can anyone advise what the issue might be? Regards Michael
about tomcat default error page
i use apache with tomcat. i don't want tomcat to generate its default error page when a error happens. instead, i want to show my error page which i set in the apache conf file. i know that i can use error-page to do this, but i don't want to do it twice -- both apache and tomcat. is there any configuration that makes tomcat do nothing about the error and just simplely pass the reponse code to apache. thanks in advance. __ 赶快注册雅虎超大容量免费邮箱? http://cn.mail.yahoo.com
Re: Memory leak from threadlocal for hot deployment
As far as I know the threads from the connector are shared between webapps. So how would Tomcat know which objects in the threadlocals are from which webapp? Or should Tomcat destroy all threadlocals of webapp A if I reload webapp B? Ronald.

Re: about tomcat default error page
Hi 李征, I don't know the answer to your question, but here is a recommendation : To avoid delays in answering your question, it is always helpful to specify : - on which platform this happens (Windows, Unix, Linux,..) - what version of Apache - what version of Tomcat - what connector you use between them (mod_jk, proxy_ajp,..) and its version. In this case, it matters very much, because the exact answer to your question may be very dependent on this information. If you do not specify it, then whoever is the expert will have to ask you first, and because of time differences you might not see his question before tomorrow, and then when you answer he may not see your answer before his own tomorrow,.. and presto 48 hours have gone by. Now if the versions of all the above that you use are fairly recent, and you use the mod_jk connector, then you may want to look at the latest release notes of mod_jk. I am not sure, but I think I remember seeing something that was more or less around that subject.

Iterations in JSF using JSTL via forEach
I am sure this is a very silly problem, however I have been struggling
with this for a while now. I am trying to iterate over a collection using
JSF and JSTL's forEach which is apparently supported in JSP2.1 (2.0) and
Tomcat 6.
I have the version number in web.xml set to 2.5 and the faces-config.xml
file set to 1.2 (see below).
I checked the version of JARS included in the WAR file and they are :
standard.jar : Implementation-Version: 1.1.2
jstl.jar : Implementation-Version: 1.1.2
jsf-impl.jar : Implementation-Version: 1.2_04-b20-p03
jsf-api.jar : Implementation-Version: 1.2_04-b20-p03
Below are the configuration files included with my WAR. I am using Tomcat
apache-tomcat-6.0.16. I have found some older examples where I got this
working, however I can't see why it doesn't work for me anymore.
Any suggestions on this would really help me out a lot.
Thanks in advance.

Where to look for connection refused errors in Tomcat6.0.18 ?
Hi, We are suspecting that during load testing with Jmeter , Tomcat 6.0.18 in Java 1.6 in Windows is experiencing more requests than it can handle . I have seen the documentation for the HTTP connector element and it says that If still more simultaneous requests are received, they are stacked up inside the server socket created by the Connector, up to the configured maximum (the value of the acceptCount attribute. Any further simultaneous requests will receive connection refused errors, until resources are available to process them. So where can we expect to see those errors in Tomcat ? Which logs ? I am using tomcat with all its default configuration . I would like to understand more of this problem before I start tweaking certain paramters ...What is the actual role of the Http Connector element ?

nested symbolic links
Hi All, I'm trying to work with symbolic links in Tomcat. I know you have to edit the context etc and it works perfectly: I have a webapp which is a symbolic link to a folder and I can successfully link to all the files in the folder, also to subfolders in that folder. e.g. http://localhost:8080/mywebapp/subfolder1/subfolder2/test.html However, when I add a symbolic link within the folders tomcat does not pick it up and does not follow the link. I've already tried restarting tomcat, among other things. E.g. http://localhost:8080/mywebapp/subfolder1/symLink/test.html returns 404. Anyone have any idea how to get this to work? I basically want to have a webapp which serves picture files and movies but I want to be able to add/remove folders to the webapp. It would be so easy to simply add/remove symbolic links pointing to the folders I want served. Tomcat is latest, java 1.6, Linux Ubuntu Hardy.

Re: Iterations in JSF using JSTL via forEach
I figured out what the problem was. I was using JSTL 1.1 rather then 1.2.
I found a version of this here :
https://maven-repository.dev.java.net/repository/jstl/jars/
I am wondering if there are any plans to include this release with Tomcat
6, or make it easier accessible.
May this is already being done, just haven't found it.
Thanks

RE: Where to look for connection refused errors in Tomcat6.0.18 ?
From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] If still more simultaneous requests are received, they are stacked up inside the server socket created by the Connector, up to the configured maximum (the value of the acceptCount attribute. Any further simultaneous requests will receive connection refused errors, until resources are available to process them. So where can we expect to see those errors in Tomcat? You *can never* see these errors in Tomcat, because Tomcat is never aware that the connection was received. The operating system's TCP/IP stack has received the incoming SYN, tried to queue the connection request on Tomcat's accept queue, failed, and simply sends a RST to close the connection. You *might* be able to monitor the total number of connection refusals at the OS level. Netstat on Windows will give you this, for example, though it combines refusals due to load and refusals due to no port being configured to accept a connection. - Peter - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Tomcat service is terminated unexpectedly (tcnative-1.dll)
Hi, I have o problem with Tomcat 5.5.26 using native DLL on Windows 2003. The service is terminated unexpectedly (regarding to the system logs). It happens very irregular (sometimes a few times in an hour, sometimes once per week). In the stack trace (attached) there is: # An unexpected error has been detected by HotSpot Virtual Machine: # # EXCEPTION_ACCESS_VIOLATION (0xc005) at pc=0x58d845a4, pid=3472, tid=588 # # Java VM: Java HotSpot(TM) Server VM (1.5.0_16-b02 mixed mode) # Problematic frame: # C [tcnative-1.dll+0x45a4] Which points to the native library. I have seen quite old (from 2006) bug 38898 [1], but there in a stack trace jvm.dll is mentioned, so I'm not sure if it's a duplicate. I don't see any other problems in tomcat logs (there was an issue with OutOfMemoryError some time earlier, but currently Tomcat can use 1,25GB and it seems to be enough). It's a test system with 1GB RAM + 1,5GB swap on a VMWare Server. [1] - https://issues.apache.org/bugzilla/show_bug.cgi?id=38898 Is it possible (using attached stack trace or by increasing a log details) determine what causes the problem?

JAVA_HOME is not found but tomcat is running. possible?
Hi all , I have a tomcat 4.x version (Perhaps it is a old version ,it is in production and we cant upgrade as of now). It is running as a window service in Windows2000 server. in the service icon i can find the path to executable: C:\Products\Apache Tomcat 4.1\bin\tomcat.exe My doubt is ,does tomcat.exe needs JAVA_HOME or JRE_HOME defined to run tomcat in this case as we are not starting tomcat using Startup.bat or Catalina.bat. If so,In my system i couldn't find any environmental varible set for JAVA_HOME or JRE_HOME... i can find only CATALINA_OPTS in it. It is also not defined in any of the .bat file as well...please help me on this.thanks Regards, Thangavel Sankaranarayanan - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

The app is not at all threaded, is 100% read-only from the database (aside from creation of temp tables which have no interaction between client requests) and the MySQL server is on another machine humming along without any bottlenecks that I can see. But of course I'm not a Java or JVM expert and have no idea what kind of interlinks can exist between different client connections. But to my knowledge they're all pretty straight forward handlers, get data from database, format, return to user I'm leaning more towards GC issues. I setup Tomcat on a 64-bit machine and tried a few configurations: -Xms4096M -Xmx4096M -server -XX:+DisableExplicitGC -XX: +UseConcMarkSweepGC -Xms4096M -Xmx4096M -server -Xms2048M -Xmx2048M -server As I went through each of those the app became more and more sluggish and a single core finally in the last configuration did this 100% CPU usage again. Now, two issues I see. First, it's not being aggressive enough at spreading the load among different cores. Second, GC does seem to be an issue. Unless I'm missing something, which I might be.

When it's running as a service, Tomcat gets the location of Java from the registry, not from JAVA_HOME.

Re: Tomcat not using multiple cores
My guesses: Your application has bad sync locking between some threads, which is causing one thread to block the others. Your application has bad database access code, which allows one thread to block others while waiting on the DB. Your application is disk bound, and the single long process is hashing the disk drives so much that is has dragged down the rest of the OS, making it very slow to respond to the IO request of the other, small tasks. You haven't configured the GC well - however, I would expect this to cause sporadic problems, rather than continuous ones. There are numerous JVM tools out there to help you with all of these issues - from the simple garbage collection monitor that comes with java (JConsole http://java.sun.com/developer/technicalArticles/J2SE/jconsole.html) to full blown tools like JProfiler (which last I checked, had a free trial) - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: Classes in tomcat\server\lib folder sometimes are visible to web application
Thank you for your quick reply. I think I understand the distinction you make between a class being available and a class being loaded, although it is a bit confusing. I suspect that if I understand this clearly, it will help me track down the cause of my problem. Given the Tomcat ClassLoader hierarchy diagram in the documentation and your clarification below, is the following correct? The Catalina ClassLoader in server/lib creates Webapp1 ClassLoader specifically for webapp1. The parent classloader of Webapp1 ClassLoader is NOT set to Catalina ClassLoader but rather to Shared ClassLoader, so requests from webapp1 to load classes are never delegated to Catalina ClassLoader. Thus a reference to a Class in server/lib in Webapp1 will result in a ClassDefNotFound error. However, the classes in sever/lib ARE aware of WebApp1, and may call methods in Webapp1 and pass in references to themselves. When this happens, Webapp1 is now working with an implementation of a class in server/lib. I assume, however, that the only way for this to work in practice is that these specific implementations are referenced in Webapp1 as Interfaces which are defined NOT in server/lib, but rather by jars higher up in hierarchy, such as common/lib. If this understanding is true, then a) if my webapp code has any specific reference (e.g. the Class name is in my code as a variable or parameter type) to a class in server/lib, I should get a ClassDefNotFoundError. b) however, if my webapp has a reference to an Interface defined in common/lib and at runtime is handed a Class that implements this class, I may not get a ClassDefNotFoundError.

That's not quite the case. Classes outside of a given classloader's branch can not be *loaded* by that classloader. However, if references to instances of such outside classes are made available to code from the classloader branch of interest, that code can use those objects. Nearly all of Tomcat's code, including the classloaders, request/response wrappers, servlet API handlers, etc., are in server/lib, yet are obviously used by application servlet code. So I understand why it does not work (class should not be visible), but why does it ever work?

I didn't recognize the significance of the use of port 8009 in the examples. Not being familiar with ajp and not seeing anything in the mod_jk or JK documentation that reminds you that this assumption exists (or suggests that you ensure an ajp connector is defined), I missed the tomcat side of the configuration. - Virgil - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

So procrun.exe is a program that wraps the JVM into a shell that does have these interfaces. tomcatw.exe is just the GUI program prunmgr.exe, renamed to tomcatw.exe. It is the GUI setup tool for procrun.exe, allowing you to tell it where to get its JVM, what parameters to start it with, etc.. Much like the startup.sh and catalina.sh do under Unix/Linux. Double-click on tomcatw.exe, then select the Java panel, and you'll see what I am talking about. So basically, under Windows, if you want to run Tomcat as a service, you do as follows : - configure your JVM environment using tomcatw.exe (prunmgr) - use tomcat.exe (procrun) as the executable for the Service that Windows will run This tomcat.exe will start the JVM, and in the JVM Tomcat (bootstrap.jar) This tomcat.exe will also catch the signal Windows is sending when it's time to shut down, and properly stop Tomcat and the JVM. Now you see why you don't find an environment variable JAVA_HOME ? tomcat.exe (in reality procrun) does not need it, because it finds the same information somewhere else (where tomcatw.exe (prunmgr) put it). (And I am not quite sure where it puts it, probably the Registry). - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

It is running as a window service in Windows2000 server. in the service icon i can find the path to executable: C:\Products\Apache Tomcat 4.1\bin\tomcat.exe My doubt is ,does tomcat.exe needs JAVA_HOME or JRE_HOME defined to run tomcat in this case as we are not starting tomcat using Startup.bat or Catalina.bat. If so,In my system i couldn't find any environmental varible set for JAVA_HOME or JRE_HOME... i can find only CATALINA_OPTS in it.

Why is that? Note that mod_jk and mod_proxy_ajp fill the same role: they use the AJP protocol to connect Apache httpd to Tomcat (or any AJP-compliant application server). mod_proxy_http does the same thing, but uses the HTTP protocol, and so has a few options missing (not exactly sure what they are). I chose mod_jk over mod_proxy_ajp for two reasons: 1. mod_jk has been around for years, and it was the only game in town when I got started. 2. I find that mod_jk is more configurable for complex deployments. I tried to switch to mod_proxy_ajp when we moved to Apache httpd 2.2.x, but I had a hard time getting it to do what I wanted it to do, so I stuck with mod_jk. Filip didn't explain his recommendation, but I believe Filip was suggesting that mod_proxy_http was more robust than mod_proxy_ajp and might not have the same problems. From my experience, mod_jk is very robust and reliable.

comment out your manager context in /conf/Catalina/localhost
!--Context docBase=${catalina.home}/server/webapps/manager
privileged=true antiResourceLocking=false antiJARLocking=false --
!--ResourceLink name=users global=UserDatabase

and look at what I see in the log

and you get 404 when accessing the manager app
