RE: Tomcat on Windows: advantages of running as a service?
Running from a service makes it a no brainer to start up tomcat when you reboot the machine as it does it automatically. Disadvantages I would see is that it hides the console and makes it difficult to changes options like JAVA_OPTS. -Original Message- From: Ben Souther [mailto:[EMAIL PROTECTED] Sent: 12 October 2005 12:12 To: Tomcat Users List Subject: Re: Tomcat on Windows: advantages of running as a service?

However, I've noticed that while shutdown.bat will shut it down if it was previously started as a service, startup.bat won't run it as a service, it starts it at a command prompt. My question is: does this matter? If I'm running on Windows are there any advantages to running Tomcat as a service? Or disadvantages to running from the command prompt?

On the 32 bit system you definitely won't get more the 2G without some kernel hacking and you may well see even less than that.

The answer is very platform specific. For example, on a normal 32-bit Windows system, each process has a maximum of 2 GB to play with, but some of that is taken up by various .dlls.

RE: session problems: www.blahblah.com versus blahblah.com
I'm not sure if this is the only or best way but you could create virtual hosts
within your server.xml, one for each domain. Then obviously your code will only
exist in one of the domains and the other you can do the redirect stuff.

the return path is blahblah.com. If www, then return to www...
Thanks for your suggestion though. I can even continue using PayPal's
encrypted buttons - I'll just make two buttons, one for www, and
theother for just blahblah, and display the appropriate button based
on current situation.
Still, I think I was hoping that somewhere in server.xml I could say
all requests for blahblah.com should be mapped to www.blahblah.com.

I would imagine the other way to do this is to implement a filter
looking for people trying to reach blahblah.com and returning a 302

cookie from the start and could be implemented accross all your webapp

RE: session problems: www.blahblah.com versus blahblah.com
I'm not sure if there is a technical way to do this or not as it's the browser that saves the cookie based on the current URL. The way I would do this is to not allow the user to create a session in one of them in the first place. ie, if they browse to blahblah.com then just redirect them to www.blahblah.com so that whenever they are interacting with the webapp. Ta Matt -Original Message- From: Michael Teter [mailto:[EMAIL PROTECTED] Sent: 15 August 2005 21:05 To: Tomcat Users List Cc: [EMAIL PROTECTED] Subject: Re: session problems: www.blahblah.com versus blahblah.com I tried that, but it's not working.

RE: Heap not expanding beyond -Xms512m
This is expected behaviour. The heap will not grow if the memory required can be gained through a garbage collection. The heap will only grow if after a garbage collection it still cannot allocate the required memory or is over a certain percentage (I forget what the default is). I would suggest that you don't in fact need 512MB if your app runs fine with no OOM in 512MB. If you really want to use the full 1GB the you'll have to use -Xms as you suggested.

RE: OutOfMemory / JMeter / Profiler questions
Hi, Tomcat always serializes sessions on shutdown and reloads them on startup. This is the default behaviour but can be changed. You are right in thinking that sessions are serialized per context though. Are you using the standard manager or the persistent manager as they are stored differently with the persistent manager. Although you don't store anything in a session, do you perhaps instanciate it? The number of sessions you currently have can be viewed from the manager application.

RE: OutOfMemory / JMeter / Profiler questions
Hi, This can be very useful behaviour. It means a tomcat instance can be bounced with only a short loss of service to the users. The sessions CAN be reused after a restart. Information on the session managers and how to disable persistence can be found in the tomcat documentation so it's a case of RTFM. http://jakarta.apache.org/tomcat/tomcat-5.0-doc/config/manager.html should get you started. It sounds like it is not a case of session persistence or sessions not being invalidated that is causing your problem however. I recommend, as always, that you get jvmstat from sun and monitor your tomcat instance with it. It will allow you to observe the jvm and the various parts of the heap and diagnose where the problem is.

RE: moving all classes to shared
I'm not sure what you're getting at here. The number of users are irrelevant to the classes. You should only use shared/classes if the classes have to be shared across web apps. Although this is not usually advised as it is good practice to keep web apps self contained. WEB-INF/classes would take precedence over shared/classes but I still don't see what you are trying to achieve. My understanding (I'm sure someone will correct me if i'm wrong) of the shared is that each class will be loaded into the classloader of each webapp so no memory would be saved, if you chose to use this area for sharing classes accross webapps. If you wanted to save memory then the common/classes is where you should put your classes. This will only classload 1 copy of the class.

RE: Session Objects
It's not impossible to make this work over a cluster but not with the included clustering classes in tomcat. You would have to write your own clustering classes. The reason why it won't work is that each singleton will be individual to a classloader and each tomcat accross the cluster will obviously have its own classloaders. The standard clustering only shares the sessions that are stored within the standard session manager in tomcat. -Original Message- From: Shey Rab Pawo [mailto:[EMAIL PROTECTED] Sent: 08 February 2005 17:44 To: Tomcat Users List Subject: Re: Session Objects Could you explain why this won't work across a cluster?

In that case then it sounds like either a memory leak or you just don't have enough memory to support your application. Do you have large objects in your sessions?

I don't think you can as tomcat uses this itself for shutting down nicely.

RE: Out of Memory when compiling JSP (Struts app on Tomcat 4.1.27)

Probably the best way to troubleshoot out or memory errors is to see what is really happening with garbage collecting, the same way that you tune it. If you can add these options, then the JVM will spit out all kinds of useful information: -XX:+PrintTenuringDistribution -XX:+PrintGCDetails -Xverbosegc But it sounds like the problem is that it's not getting the options. What you really need to figure out is exactly how the service is getting started. For instance, if it's calling tomcat.exe then I don't believe that the JAVA_OPTS environment variable is ever looked at since that is in the startup.sh and startup.bat files (I'm not 100% certain about that however). Find out how it's starting. Also, post the version of Java you are using (since the options I gave you above don't work on all versions, I think 1.4 and up or 1.3 and up). But the -Xverbosegc works all the way back to 1.1 if I'm correct.

I am using Tomcat 5.0.19 on Windows XP SP2, J2SDK 1.4.2_03. I have a serious memory problem with Tomcat, it just EAT memory without explanation, until OOM error occurs. The Java.exe process in the windows task manager reports using between 95Mb and 105Mb after the startup of the webapp. I do not use Xms Xmx options in dev mode. It just grows until it runs out of memory. There is not much memory available (around 150Mb), yet it should be enough for a few classes, JSP and almost not data in the database. Like a big boy, I decided to use Jprofiler demo to figure out where the memory leak was, to see that there is only 20 Mb allocated by the VM!!! So where does the rest of the memory goes? I do not use any non-java library (dll), I don't think I'm doing anything special. The app use a the Versant JDO implementation (instead of direct JDBC) using MS SQL server. But hey, the app is still in dev mode, with only the developpers using it, the DB is (almost) empty, so the amount data is not in cause. Anyways using 20Mb of heap is very reasonable (there will be at least 1gb available in production), but why is the java.exe process eating memory like a pig an the profiler is not showing where the mem goes? (by the way, I did deleted ALL the filters from Jprofiler). If the app would take 2Gb in memory I would not care, as long as I know what is using the memory. I did profile an app running on 5.0.18, and the same magic happens, the memory used by the java.exe is far from close to what the total heap size of the VM reports to be. Am I going crazy? Any ideas?

You will need to add both log4j.jar and commons-logging.jar (not commons-logging-api.jar) to common/lib to enable Log4j logging for Tomcat-5.5.x itself. For your own app, do you use actually use the commons-logging api or just the Log4j api? If the latter, don't bother with commons-logging. In fact, try to avoid it like the plague. If you do require commons-logging for your webapp logging, I'm not entirely sure whether it is ok to have log4j.jar in WEB-INF/lib and commons-logging.jar in common/lib or if they have to be together. There could be classloader issues if you separate them. I'm not really sure. commons-logging issus are outside the scope of my knowledge. Thanks for the answer. I am trying for both. commons-logging.jar + log4j.jar are in commons/lib. But here is the question: I do not see why they also have to be on the webapp WEB-INF/lib, since it should be shared because they are already on commons/lib. If you share the common/lib instance of Log4j with your webapp, you will be using the same logger repository as the application server. There is one configuration per logger repository. If force reconfiguration within this already configured logger repository, your old configuration will be blown away. The idea Putting another copy of Log4j.jar in WEB-INF/lib in addition to the one in common/lib is to take advantage of Tomcat's classloading behavior which is child first (recommended by the servlet spec) rather than parent first (normal Java2 classloading behavior). Because each webapp looks locally for libraries first, it will find an instance of Log4j that is not in use by any other application. Therefore, the default logger repository will be distinct from that of the server and from that of any other webapp. You can configure to your hearts content without stompting on others' logging configuration. There is a way to separate application logging while sharing the same instance of Log4j and that is by using a repository selector. I would avoid this until Log4j-1.3 is released. It is more difficult to use a repository selector in Log4j-1.2. 1.3 makes it very simple. I recommend you use the first solution until Log4j-1.3 is released. If I do not put them in the webapp WEB-INF/lib, logging for the webapp does not work. You are counting on autoconfiguration here. If you have an instance in common/lib, but not one in WEB-INF/lib, the logger repository of the one in common/lib will already have been configured by the time your app is initialized. Autoconfiguration is not performed more than once. Your webapp, in this case, will be using the configuration of the config file at the server level (in common/classes). Again, with a repository selector, your app config could be separated from the default logger repository. Note that in Log4j-1.3 you will need to perform configuration as there is no autoconfiguration, at least via classloader discovery of config files, on non-default logger repositories. As I said, I got it working already, but this is just curiosity. Hopefully I explained things better and piqued your curiosity about repostiory selectors in Log4j-1.3 :-) Jake Thanks, Marcelo. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] Any opinions expressed in this E-mail may be those of the individual and not necessarily the company.

RE: Tomcat 5.5 Webapp logging.

I'm using solaris so no daft windows service difficulties. Hopefully I can capture the standard out of an app when I get the webapp log4j configuration to work.

Ta Matt -Original Message- From: Jacob Kjome [mailto:[EMAIL PROTECTED] Sent: Thursday, December 09, 2004 6:16 PM To: Tomcat Users List Subject: RE: Tomcat 5.5 Webapp logging. Quoting Dale, Matt [EMAIL PROTECTED]: This sounds like kind of what I want but you've confused me. I basically want the System.out and stdout from a particular webapp to go to a specific log file that is rotated and seperate for each webapp. I'm not sure how you would separate System.out from any individual app. If you run Tomcat-5.5.x as a service (at least on WinXP, which is what I use currently), it will automatically write to a stdout.log file *and* give you daily log rotation for free. I've now got log4j working with a log4j.properties in common/classes. Everything is now logged to a rotated log file which is hunky dorey from that point of view. My second requirement is that the webapps be seperated into different log files. This, i've had trouble with, i've placed a log4j.properties in WEB-INF/classes but it seems to be ignored (log4j.jar is in the WEB-INF/lib). If you mean System.out output, then there isn't much you can do with the standard console appender. It will all go to one place. However, your normal log4j defined loggers should be working according to your properties file. log4j.properties in WEB-INF/classes with log4j.jar in WEB-INF/lib should create a separate logging environment from the server for each webapp you do this with. I could seperate things out in the the main log4j.properties but at least one of the apps is comprised mostly of jsps without a specific package so i'm unsure how to do this. You can still name your JSP's according to some psuedo-package naming scheme. Loggers aren't tied to your packages. This is just the standard way of naming loggers to make naming predictable and easy to confgure. Name them whatever you want. But where you've really confused me is the mention of log4j.xml, this is the first i've seen on it. Could you perhaps tell me where it goes and point me to something that can help me decide what to put in it? So, you didn't realize that Log4j could be configured using an XML config file? Well, it can. However, the DTD for Log4j prevents using Tomcat's host and context logger names for the reasons I stated (which, again, is not longer an isssue in Log4j-1.3 because the DTD is not used anymore). For instance, the following is illegal because the name attribute is defined by the DTD as of type ID and the [ and ] are illegal characters... logger name=org.apache.catalina.core.ContainerBase.[Catalina].[localhost] /logger If you are unaware of this naming scheme, see the Tomcat-5.5.x docs. The alternative is to use a properties file and use... log4j.logger.org.apache.catalina.core.ContainerBase.[Catalina].[localhost] In short I could do with a bit more detail if you wouldn't mind. Hopefully that cleared things up a little bit. Jake Ta Matt -Original Message- From: Jacob Kjome [mailto:[EMAIL PROTECTED] Sent: 09 December 2004 16:55 To: Tomcat Users List Subject: Re: Tomcat 5.5 Webapp logging. So, you want System.out stuff to go to the stdout, is that right? Just set up a console appender. Note that if you want to log to Tomcat's specially named localhost and context loggers, you'll need to use a log4j.properties file rather than log4j.xml because the naming pattern violates the XML spec's naming scheme for attributes of type ID. This is only true for Log4j-1.2.x. In Log4j 1.3, we no longer use a DOMConfigurator, but the new JoranConfigurator which doesn't use a DTD and, therefore, doesn't define logger name attributes as of type ID. You can define loggers and appenders in a way where Tomcat's info can go to a separate log file than the stdout console or stdout log file.

RE: Tomcat Running out of Memory
Hi, As an addition to this i'd like to add that if you are not explicitly increasing your permanent generation then I'm not surprised that many JSPs would fill it up. You will probably find that the default Maximum size of the Permanent generation is 64MB and it is that which is filling up and not the full 1850MB of your heap. A tool you should look into is jvmstat which is available from sun and gives you a grahical representation of the heap real time so you can see what is running out. As a tip -XX:MaxPermSize=256M might be a good option for your JAVA_OPTS.

None of these pages pull from a backend, the java was merely used to provide a persistent border. Are these JSPs precompiled? -Max heap size is set to 1850 megs, (which from what I understand is the max on a 32-bit system). It's not. The max in JDK 1.4 is 2GB for the vast majority of 32-bit platforms, including yours. You'd have to search far and hard to find any platform that imposes a memory limit that's not a power of 2 ;) -The server has 4 gigs of total RAM. Which doesn't matter because you're only giving the JVM 1850MB. I've done some searches on Google and in the archives and I can't seem to find any way to turn up the frequency of the garbage collection. To turn up the frequency of garbage collection, you would use several JVM options, as documented at http://java.sun.com/docs/hotspot/VMOptions.html. In fact, the related document at http://java.sun.com/docs/hotspot/gc1.4.2/index.html is vital reading. Everything seems to indicate that once a JSP is loaded into memory it stays there. Why wouldn't it? It's a compiled class that goes into the permanent generation (not the heap). Classes themselves (as opposed to their instances) would be unloaded only if possible and only at time of dire memory trouble, as judged by the VM. Is there some way to increase the max heap size? Yes, using the -Xmx parameter. Or some way to increase the frequency of garbage collection? Yes, see the VM options above. Or any other way to slow down the memory usage? Yes, to critically inspect the design and implementation of your app such that less memory is used. This is typically a performance tradeoff, as you would cache and retain less in memory, leaving more in the database or disk as needed. If you're not precompiling your JSPs, you should: compiling 5000 JSPs is a significant drain on resources, although those resource should largely be released.

RE: Tomcat 5.5 Webapp logging.
This sounds like kind of what I want but you've confused me. I basically want the System.out and stdout from a particular webapp to go to a specific log file that is rotated and seperate for each webapp. I've now got log4j working with a log4j.properties in common/classes. Everything is now logged to a rotated log file which is hunky dorey from that point of view. My second requirement is that the webapps be seperated into different log files. This, i've had trouble with, i've placed a log4j.properties in WEB-INF/classes but it seems to be ignored (log4j.jar is in the WEB-INF/lib). I could seperate things out in the the main log4j.properties but at least one of the apps is comprised mostly of jsps without a specific package so i'm unsure how to do this. But where you've really confused me is the mention of log4j.xml, this is the first i've seen on it. Could you perhaps tell me where it goes and point me to something that can help me decide what to put in it? In short I could do with a bit more detail if you wouldn't mind. Ta Matt -Original Message- From: Jacob Kjome [mailto:[EMAIL PROTECTED] Sent: 09 December 2004 16:55 To: Tomcat Users List Subject: Re: Tomcat 5.5 Webapp logging. So, you want System.out stuff to go to the stdout, is that right? Just set up a console appender. Note that if you want to log to Tomcat's specially named localhost and context loggers, you'll need to use a log4j.properties file rather than log4j.xml because the naming pattern violates the XML spec's naming scheme for attributes of type ID. This is only true for Log4j-1.2.x. In Log4j 1.3, we no longer use a DOMConfigurator, but the new JoranConfigurator which doesn't use a DTD and, therefore, doesn't define logger name attributes as of type ID. You can define loggers and appenders in a way where Tomcat's info can go to a separate log file than the stdout console or stdout log file.

RE: OutOfMemory! Tomcat meets sudden spikes of used memory sometimes.
The fact that you have the same symptons in tomcat 4 and in 5 points towards your application as being the culprit. Is there any reason why you chose tomcat 5.0.18 instead of one of the many newer releases? I would find another profiler that works with both and try your tests again. Ta Matt -Original Message- From: Li Zhenxing [mailto:[EMAIL PROTECTED] Sent: 08 December 2004 13:47 To: [EMAIL PROTECTED] Subject: OutOfMemory! Tomcat meets sudden spikes of used memory sometimes. Hi folks, I am puzzled by the situation that Tomcat 4.1.31 meets sudden spikes of used memory sometimes. Then it will increase to throw OutOfMemory Exception and tomcat is hanging. Those memory spikes appear in my Web application for a long time. The odd thing is that it does not seem to progressively go up but rather spike up with each next full GC will clean less objects out. This is three pictures of the gc log. http://my.sme.cn/jsp/main/memoryleak.png http://my.sme.cn/jsp/main/memoryleak2.png http://my.sme.cn/jsp/main/memoryleak3.png I used HPjtune tool to watch the gc log. System using windows 2000 server, 2*CPU, 2G memory, JSDK 1.4.2_05, tomcat 4.1.31, And set -Xms1250m -Xmx1250m -server -XX:+UseParallelGC -Xloggc:D:\tomcat\logs\gc.log At first, I doubt if my app program has memory leak. But the application only runs by JSPs and javabeans.(I abandon using DBCP pool and any thread operation because of the memory leak.) I think simple JSPs can't cause the memory spike. I have a monitor.jsp to show my application status. http://my.sme.cn/jsp/main/monitor.jsp The WebSite uses normally below 100M memory heap through my monitor.jsp. It can run a few days, or a few hours before the spike appears. It is irregular. I read the access_log and want to find answer. But I can't find any clue. Then, I think tomcat 4.1.* has some bugs causing the memory leak. I upgraded my application to tomcat 5.0.18, but I met same thing. The WebSite's hits is more than 200,000 per day. I try to use OptimizeIt 6 profile to watch memory status, but OptimizeIt always exits after runs 2~3 hours. I guess this program maybe need using progressive memory of system to log things and analyze those when I notice Optimizeit used 1.6G system memory.(and OptimizeIt 6 profile only runs under tomcat 4.1.*! So I return to tomcat 4.1.31) I don't know how to cause the thing and how to find solution. Any suggestion is appreciated. Thanks.

RE: clustering help
How do you distinguish between the two servers in your URL?
For the clustering to work you need to hit both through a single entry point
such as a load balancer.
This is because the session id is stored as a cookie which is stuck to a
hostname, an inherent cookie behaivour. If when you hit the second server you
just change the hostname in your URL then this is never going to work.

RE: Runtime.exec security issue?
This behaviour makes sense to me as you are trying to display an application but there is not necessarily a windows display associated with Tomcat so it doesnt know where to launch the app to. And by the lack of error message i'd guess that the application is actually getting launched but not displayed on the console. -Original Message- From: andy wix [mailto:[EMAIL PROTECTED] Sent: 29 November 2004 09:45 To: [EMAIL PROTECTED] Subject: Runtime.exec security issue?
