Re: Deploy 1st Service to Tomcat proper
Hi Michael, Thank you for your reply. I should hasve pasted the error. The reason I didn't wa sthat I assumed that my method of export.wardeploy was incorrect. When i click on the application in my Tomcat Manager page I get a HTTP Status 404 error telling me that my web service (requested resource) is not available. There is no error in the $Tomcat/logs folder. I checked, manager, catalina, stdout, localhost, jakarta_service,host-manager and admin logs. But I could see no error. In catalina.2009.X.X.log when I start Tomcat it says it deploys the service. When I stop Tomcat I get a message in stdout_2009.X.X, a log4j error message telling me that LogManager.repositorySelector was null. This message is coming from my service as I used to get it within Eclipse before I set up Log4j correctly but I don't think this is the cause.. this link would indicate it might not be.. http://www.mail-archive.com/log4j-u...@logging.apache.org/msg09782.html Any ideas welcome, Thanks again, Tori Michael Ludwig-6 wrote: Toriacht schrieb am 28.01.2009 um 14:48:59 (-0800): Exportwar exports a war file with the same name of my project.

It is probably in one of the log files in $Tomcat/logs. Also, the java project had a lot of dependencies on jar files. Do these get exported or do I have to manually deploy/copy these to my Tomcat server? That depends. You can use jar tf your.war to check what's in the JAR.

You might be able to get it to work with lots of extra libs and some tweaks to the source. Don't know about the 4.x Tomcat levels. Most of Tomcat 4 will run on a 1.2 JVM. Some things don't work, the CGI serv;et being one of them if I recall correctly. To get back to the original question, Tomcat 7 which will implement the servlet 3.0 spec will require a 1.6 JVM (as required by the spec).

Advanced IO and Tomcat
Hello everybody! I'm doing a research on the topic Does Comet scale?. I have already developed a solution using some Javascript and Wireshark measurements. During my research I was looking for people who did this already or could give me any idea of how to configure my setting and so on. But there was not too much information. And so I developed the following 3 test cases: 1. 2 Clients, 1 initiates Updates on the resource and both receive these. 2. 2 active Clients initiating Updates on the resource and 1600 passive Clients receiving these. 3. 8 active Clients initiating and receiving Updates. (This test will be soon coming with 64 concurrent active Clients) All these test cases have shown that Comet, referring Tomcat 6, performs very well. Now at this point of my research I would be very interested in how you tested the new Comet feature. This would very much help me to evaluate my own efforts. With best regards Philipp Abromeit

Indicator APR is loaded - TC 5.5
Hi guys, I'm a bit puzzled: I'm running a few TC-instances, all of them using TC-native and APR. I'm used to that, once the APR is loaded, there's a line in the logs stating that the APR is being used , or, if mis-configured, that the APR cannot be found. On my Tomcat 6 on Debian this works like charm: catalina.out:INFO: Loaded APR based Apache Tomcat Native library 1.1.16. catalina.out:INFO: APR capabilities: IPv6 [true], sendfile [true], accept filters [false], random [true]. However, on my Tomcat 5.5, also running on Debian, I don't find *any* information.

Re: enableLookups=true, getRemoteHost returns ip
Thanks, Konstantin, for the thorough response! I was failing to grasp that the forward lookup portion of the method was failing because there was no forward dns mapping. I thought it was failing locally inside the java code, not in the dns system. To confirm the lack of a dns mapping, I used host ip address and received a host name. Then I tried host host name and got a host not found message. Since it's not critical that I prevent spoofing in my app, I'm using a variation of the jndi dns code you pointed out in http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4670102.

Re: Indicator APR is loaded - TC 5.5
Ok, since there's no comment by now, I'll try to rephrase my question: As I wrote, said Tomcat instance is fronted b Apache HTTPD via mod_jk. This means, that Tomcat in the current confuguration is only serving dynamic content, such as JSPs and Servlets, but no static HTML. I guess that the APR-message usually showing up in the logs IMHO is triggered by the APRLifeCycleListener (true?) Could it be that the APRLifeCycleListener is loaded lazy, and since no static HTML is served, the APRLifeCycleListener ist not loaded and therefore no logging-message is showing up? Would appreciate if anyone here could confirm this behaviour.

Performance of APR
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 All, I often hear folks on the list mentioning that since the APR library is the same as that which runs under Apache httpd, the performance of the two ought to be the same for static content. I'm not so sure, so I'm asking about it. Since Tomcat's request processing is all in Java (right?), the request must first be processed by Java, including creating all those objects that are included in the request. I realize that some of those objects are created on demand (for instance, Tomcat doesn't parse all the GET and POST parameters from the request until the handling servlet actually requests one of them), but all that stuff still happens. Before the request is handed-off to APR. Is the same true of Apache httpd; that is, since Apache must do a bunch of pre-processing of the request before the bytes are actually streamed, does the performance of the two actually end up being the same? I can't help but suspect that Apache httpd will outperform Tomcat even when it's running APR for static content, merely due to the overhead of the JVM, heap management, etc. (which I realize are fairly minimal). Can anyone give a non-flame comment or point to an actual performance comparison with decent data?

Can anyone give a non-flame comment or point to an actual performance comparison with decent data? Serving static content is an I/O-limited task. So whether the server code takes 450ns or 500ns to do the processing required is not significant. Provided the interface with the kernel is optimal, any server will perform roughly the same because it's the kernel doing all the work. I think you also need to factor in the labor cost to manage two different servers. I know that in our production deployments we could buy many many machines for the cost of the time we've spent trying to make AJP work. Tomcat could be 10x slower than Apache and I'd still use it to avoid the hassle. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Can anyone give a non-flame comment or point to an actual performance comparison with decent data? yeah, check the link (and buy the book :-)) regards Leon - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

commons-logging problem
I have a web application running in Tomcat 5.5.27 with JDK 1.5.0_16-b02 on Windows XP SP3. log4j-1.2.15.jar and commons-logging-1.1.1.jar are installed in WEB-INF/lib and there is a context.xml file in META-INF. When packaged as a war file this combination reliably produces the exception shown below in the Tomcat console under the following circumstances: 1. deploy the war file (e.g. using Tomcat HTTP manager) 2. stop and restart tomcat 3. undeploy the war file 4. deploy the war file Note that to demonstrate this it is necessary to have both a context.xml file in META-INF and commons-logging-1.1.1.jar in WEB-INF/lib. Also, the problem disappears if you downgrade to commons-logging-1.0.4. Otherwise the contents of the application don't seem to matter - it can be demonstrated in an application containing no classes or other libraries. The only other thing I've found to have an effect is the *name* of the application. commons-logging-test exhibits the problem, but in at least one test renaming the same application to start with a letter later in the alphabet did not (possibly to do with the order applications are loaded)? I suspect this is a bug either in Tomcat or the logging sub-system, but these things are notoriously tricky and before reporting it as such any comments or help would be very welcome.

Force loading a page on restart
I would like to know if it is possible to force a user to a certain page when Tomcat restarts. In my application, if Tomcat is restarted after the user displays a page, the user is not aware of the restart until he/she clicks on a link or button on that page. Then, Tomcat will automatically redirect to the login page. This is OK so far. However, the problem I have is what happens after the user logs in. I am using RichFaces and after login, there usually is some AJAX response being processed, but this usually leads to a page only being partially updated. I would like to force full reload of a specific page, say the users's home page, if Tomcat is restarted after the user has authenticated. How can i do this? I am using Tomcat 6.0.18 and RichFaces 3.3.0. Martin

Excel file in Tomcat Virtual Dir has junk data in it.
Hello Everyone, I have set up a Virtual Directory (Directory Listing) in Tomcat. We use this to distribute documents and reports. The way we do is put the documents to be distributed in this directory on the server and all our user go to this virtual directory by accessing a URL and view/get their reports. I have put a .xls file in there, and when we open it - it opens in the browser itself and what it seems to have is junk data in it. (unreadable). However instead of clicking it to open, if we do Save the target as.. and save it in the local machine and change the extension from .htm to .xls the report comes to full-life and its all good. We used to have similar virtual directory in Apache before. I remember that if we clicked on the .xls report, instead of opening it in the browser, it would begin downloading it to the local machine as an Excel file, so that was very good. Is there any settings in Tomcat which we can set so that instead of opening files in the browser itself, it would download it to the users' PC with the correct file extensions? Any insight and recommendations in this regard would be greatly appreciated.

Check if it contains a section like this one : mime-mapping extensionxls/extension mime-typeapplication/vnd.ms-excel/mime-type /mime-mapping If not, add it, restart Tomcat and retry. When Tomcat (like other webservers) sends data to a browser, it tells it what kind of data this is, via a HTTP header sent along with the data. The browser should normally accept this information, and handle the received data accordingly. Now, if the browser you are using is Internet Explorer, it is possible that even when the webserver tells it what kind of file it is sending (like application/vnd.ms-excel above), IE in it's wisdom might do its own check and decide otherwise. I would not be surprised if even for an Excel file it got it wrong. In that case, you might want to try the same link with Firefox, just to check. There also exist tools, for IE and Firefox, which allow you to see exactly what the server is sending to the browser in terms of description of the file. If your problem persists, you might want to use one of those to find out for sure.

Re: commons-logging problem
Thank you - disabling the PermGen fix by setting org.apache.catalina.loader.WebappClassLoader.ENABLE_CLEAR_REFERENCES to false stops the exception from appearing, as you suggested. Doing this does make me a bit nervous though, as we've had problems with PermGen memory exhaustion in the past. It also suggests that this fix has problems of its own. I have a very simple test war that demonstrates the problem - is it worth filing a bug report to pinpoint what's going wrong in this particular case? Also is it a supported configuration to use commons-logging and log4j in WEB-INF/lib? I can't find a definitive statement one way or the other in the Tomcat docs, but it seems necessary to do this to get debugging info from digester etc. Unless I'm missing something.

Re: Performance of APR
David Boreham wrote: I think you also need to factor in the labor cost to manage two different servers. I know that in our production deployments we could buy many many machines for the cost of the time we've spent trying to make AJP work. Tomcat could be 10x slower than Apache and I'd still use it to avoid the hassle. Of course if you need load balancing across multiple Tomcats you either need Apache or a dedicated load balancer appliance. Also Apache 2.2 allows easy configurable authentication (or a single resource/URL) against multiple authentication repositories, e.g. multiple LDAPs. Last I investigated Tomcat did not. I'd love to see a simple world of only needing Tomcat and no front-end web server. For starters Tomcat should provide high-performance load-balancing from one front-end Tomcat to multiple backend Tomcats and easy authentication against multiple LDAPs. After that there are other issues, e.g. security providers that provide Apache but not Tomcat plug-ins, but these would seemingly impact far fewer folk. In fact, I'd bet fairly few of us need the multi-LDAP stuff -- just giving good, high-performance load balancing over Tomcats by a Tomcat would be huge. -- Jess Holle - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Re: Installing Tomcat
The main rule of thumb is that with simplicity comes limitation, and with flexibility comes complexity. A Tomcat install may seem complex at first glance, but it's because it can do so much with it (IMO). There are *so many* things you can do with it, and so many different ways you can install it. It can seem a bit overwhelming at first. Once you're familiar with how you want to set it up though, it's really pretty simple. You're taking the right road here. You're becoming familiar with it and once you do that, everything becomes a lot easier to understand. HTH.

Sorry for not responding earlier, things have been a little hectic this week.
I just got try it today and here is what happened:
I just tried the same thing, with no problems.
I made this class:
I don't see a package clause in your code, nor are the imports shown. Here's
the entire code I used, including the poor man's logger, System.out:
package mypackage;
import javax.servlet.http.HttpServletRequest;
import org.apache.catalina.Globals;
public class StaticContentServlet extends
org.apache.catalina.servlets.DefaultServlet {
protected String getRelativePath(HttpServletRequest request) {
// Are we being processed by a RequestDispatcher.include()?
if (request.getAttribute(Globals.INCLUDE_REQUEST_URI_ATTR) != null) {
String result =
(String)request.getAttribute(Globals.INCLUDE_PATH_INFO_ATTR);
if (result == null) {
result =
(String)request.getAttribute(Globals.INCLUDE_SERVLET_PATH_ATTR);
}
if (result == null || result.equals()) result = /;
System.out.println(StaticContentServlet returning + result);
return result;
}
// No, extract the desired path directly from the request.
String result = request.getPathInfo();
if (result == null) {
result = request.getServletPath();
} else {
result = request.getServletPath() + result;
}
if (result == null || result.equals()) result = /;
System.out.println(StaticContentServlet returning + result);
return result;
}
}
I added it to my web.xml file:
Mine is almost the same, with the addition of a listings param:
servlet
servlet-namedocs/servlet-name
servlet-classmypackage.StaticContentServlet/servlet-class
init-param
param-namelistings/param-name
param-valuetrue/param-value
/init-param
load-on-startup1/load-on-startup
/servlet
just so the /docs mapping would do something useful. (The servlet mappings are
identical to yours.)
Referencing the URLs:
http://localhost:8080/sample/docs
http://localhost:8080/sample/docs/test.txt
got me this result in stdout:
StaticContentServlet returning /docs
StaticContentServlet returning /docs/test.txt
and the expected directory listings and the text file contents in the browser
window.

Is *src* really the right place to find the DLLs? I realize it's long, but can you post the full string? Where you see ... I can see what looks like the value of my PATH. Can you post the full version of that as well? Plus, in my case, C:\WINDOWS\Sun\Java\bin. Shouldn't matter, as this doesn't exist. Yes, I now realize I get that too, when Tomcat is run as a service (I don't have such a directory either). I presume the tomcat6.exe launcher adds it for prehistoric reasons. So I guess there is something wrong with Tomcat here. I can't see how, unless there's something really odd going on with the classloader hierarchy. Can you post the full stack trace of the UnsatisfiedLinkError? I wonder if there's a custom classloader that's getting in the way, since I don't have any problems with Tomcat's set of classloaders accessing native libraries specified by the java.library.path setting. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

Of course if you need load balancing across multiple Tomcats you either need Apache or a dedicated load balancer appliance. Also Apache 2.2 allows easy configurable authentication (or a single resource/URL) against multiple authentication repositories, e.g. multiple LDAPs. Last I investigated Tomcat did not. The new combined realm (as of 6.0.19) will let you do this. No Tomcat only load balancing though. Mark I'd love to see a simple world of only needing Tomcat and no front-end web server. For starters Tomcat should provide high-performance load-balancing from one front-end Tomcat to multiple backend Tomcats and easy authentication against multiple LDAPs. After that there are other issues, e.g. security providers that provide Apache but not Tomcat plug-ins, but these would seemingly impact far fewer folk. In fact, I'd bet fairly few of us need the multi-LDAP stuff -- just giving good, high-performance load balancing over Tomcats by a Tomcat would be huge. -- Jess Holle - 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

Tomcat Clustering trouble when starting up under high load
Hello all
I´m Mikel, and me and my workmates have already been a while testing our
environment in order to establish a in memory session replication cluster
for our servers. The thing is that our servers are often loaded with up to a
thousand (1000) and more sessions (and now, we have three tomcat nodes in
different machines working in a load balancer). In hot moments, I have
counted up to 4500 sessions distributed between the three servers.
So, I'll tell you the main configuration our production environment. Web
servers:
Two windows server 2003 with IIS and isapi_redirect.dll conector.
App servers
node 1 2: IBM Xseries_3550 Intel Xeon CPU 5150 @2,66GHz, 2,00 GB RAM,
Windows 2003 Server R2
node3: IBM XSeries_366 Intel Xeon CPU 3,20Ghz, 3,00 GB RAM, Windows Server
2003 R2
In our development environment, where we have been making our tests, we have
2 tomcats in two different machines
node 1: Intel Xeon CPU E5440 @ 2,83GHz, 1,00 GB RAM, Windows Server 2003 R2
node 2: IBM XSeries_3550 Intel Xeon CPU E5440 @ 2,83 GHz, 2GB RAM, Windows
Server 2003 R2
We have been testing the Tomcat 5.5.9 that we are using in production,
finding some trouble, even after aplying the clustering fix pack from
https://issues.apache.org/bugzilla/show_bug.cgi?id=34389 . Finally, we took
the decission to upgrade to last Tomcat 6 available, version 6.0.18, to see
if the announced refactoring of cluster subsystem could solve our trouble.
After all this prety long intro, I'll tell you the reason of my request.
When we test the cluster (in development environment) with both nodes
running, we create up to a thousand sessions, keeping alive and modificating
about 500. So, we can see that all of them get replicated to the other node
quickly . The trouble comes when, after shutting down one of the instances,
we start it again (while the half of the alive sessions are still beeing
modified by the JMeter test). In our tests, the starting tomcat instance
finally gets hunged when receiving sessions from the alive node.
Theese are the traces seen in the catalina.log of node 1 when starting it:

Well, actually when it comes to IO performance Java outperforms C, so I wouldn't place my money on old bets like C is faster because its C. It isn't. When it comes to the large file serving then the OS sendfile support in Tomcat Native outperforms the standard Java IO by an order of magnitude (In some of my tests up to 4 times), and with constant memory usage regardless of file size. There is also some other advanced features like Thread per request processing model, and much faster OpenSSL compared to JSSE.
