new user trying to get a sample servlet to run from w3school
Hi-
I get the following error msg on tomcat at this URL:
http://localhost:8080/examples/HelloWorld
I am wondering it seems like I am getting the maven project to build in
Moonshine
IDE. then I put a new web.xml file in the examples directory in the tomcat
server
unzipped files. Then, I try to copy my class over and run the example, and I
get this error
msg. listed below.
I just want to try to deploy one or two servlets which I know little about, so
I can switch to blazeds and use tomcat. It's kind of like a helloworld to
tomcat intro.
I am hoping to use apache royale with blazeds.
Any help is greatly appreciated. THANKS. j. mcnamara

Re: connecting tomcat server to eclipse java ee
Well…. When you see that message, Eclipse has gone through it’s table of Tomcat version possibilities known at the time your version of Eclipse was published, and hasn't found it. Must’ve come *after*. Therefore, The version of Eclipse you need to use has got to have been released *after* the version of Tomcat that you’ve got installed. That way, it will have that version of Tomcat in it’s table of known Tomcat versions it can choose from. Folks, do you concur, or am I wrong here? - Jim Henk > On Mar 9, 2023, at 6:36 PM, Stephanie Panah wrote: > > Help please.

configuring Tomcat on ASUSTOR NAS???
Hi. I’ve got an ASUSTOR NAS drive, and have used their utility to install their port of Tomcat. Yes, it *does* come up successfully. However, when I use their folder browser to go to the Tomcat directory, I see a *very strange* folder tree, and I can’t find the conf directory anywhere to assign users to groups, so I can get into the Manager app, for instance. Does anybody know how I’m supposed to get in to configure Tomcat on the ASUSTOR NAS? Where the heck is the conf directory? And no, there doesn’t seem to be anywhere to access env vars, including CATALINA_HOME, so there’s that, as well. - Scratching head in San Diego. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
Tomcat is hanging up when I try to access local host:8080
I am having a problem when I am in my browser trying to access html documents on my localhost. I am running apache-tomcat-8.0.50 on Bunsen Labs Lithium release, which is a derivative of the Debian "buster" release. I have tried accessing localhost:8080 in both Firefox and Opera with the same results, so I suspect the problem is either with the Tomcat server or the OS support of port 8080 is failing somehow. I ran into this problem several days ago. I had no idea how to fix the failure of port 8080, so I reinstalled the operating system. A few days have gone by, but I have now run into the same problem. I can't keep re-installing the O/S, so it is time to try to figure the root cause of the problem and try to fix it. The problem occurs when I enter "localhost:8080/someURL" or just "localhost:8080" in a browser search bar. If I do this, the browser window tab hangs up and indicates that it is searching, but nothing comes up in the tab. It just hangs there. I think the browser is searching because in the window tab where the tab name is, a small dot bounces back-and-forth, indication the widow has begun the search. Note that if I try to enter a URL to the outside world, e.g. www.ebay.com, the browser will work properly and the requested page will be displayed. If I ping my local host at 127.0.1.1, I do get the expected response. If I look at the Firefox Web Console, no errors are indicated. If I try to access a URL other than at port 8080 of the localhost, everything works fine. I tried stopping and starting tomcat a number of times and the behavior did not change. I then decided to look at the catalina.out log file. I found that when I shutdown tomcat, nothing was sent to the log. But when I restarted tomcat, the catalina.out file was appended with the information that I am attaching as "catalina.append.txt". This looks suspicious to me, but I don't know how to interpret the information. Can someone tell me what, if anything, the log indicates? I am fairly experienced with Linux system administraion, but this is a case I am stumped on what testing can be done or where or what I should examine. Any suggestions on what look for on the PC will be appreciated.

Yes, the file is there and readable. The NTFS permissions have only the built-in SYSTEM, CREATOR OWNER, and domain administrators group as having any kind of access to the folder. This was working before I started upgrading.

Upgraded to 8.5.63, ssl stopped working...?
I had 8.5.41 working and decided to do the upgrade to 8.5.63 today on Windows Server 2012r2. I've had success with stopping the service, renaming the tomcat directory, putting the unzipped files of the new version in its place, and dropping in the server.xml, and web.xml files to replace the default files. As well, I copy over the webapps folder for the site, then restart the service. This process has worked many times before. When I did this today, the service would not start for some reason. So I renamed the folders back to their original names, and then ran the uninstall from the add/remove programs. I ran the install executable on 8.5.63, dropped in the webapps folder, and the server.xml and web.xml files and the service started, but the site never loads, even on localhost. This is the server.xml I'm using, first configured back in 2017. I could probably pare it down, but once it started working, I didn't feel like messing with removing the commented sections. :)
RE: [OT] Spring Security LDAPS authenticator won't trust TLS cert
Hi Chris,
Are these typos for trustStrore (should be trustStore, yes?) from below from a
copy/paste?
> -Djavax.net.ssl.trustStrore=conf/truststore.jks
> -Djavax.net.ssl.trustStrorePassword=[the password]
I'm not a spring expert at all but everything else you mentioned looks right to
me, that's the only thing that looked off.

All,
Off-topic, but I know there are plenty of Spring users on this list who can
probably help me figure this out.
Recently, Let's Encrypt switched from using their soon-to-be-expiring
intermediate certificate:
Owner: CN=Let's Encrypt Authority X3, O=Let's Encrypt, C=US
Issuer: CN=DST Root CA X3, O=Digital Signature Trust Co.
Serial number: a014142015385736a0b85eca708 Valid from: Thu Mar 17 12:40:46
EDT 2016 until: Wed Mar 17 12:40:46 EDT 2021
To this new one:
Owner: CN=R3, O=Let's Encrypt, C=US
Issuer: CN=DST Root CA X3, O=Digital Signature Trust Co.
Serial number: 400175048314a4c8218c84a90c16cddf Valid from: Wed Oct 07 15:21:40
EDT 2020 until: Wed Sep 29 15:21:40 EDT 2021
We are using LE for our LDAPS server and our latest-issued certificate is
signed by and includes the above ("R3") certificate in the server's certificate
chain when contacted by a client.
As soon as this switch occurred on Saturday, two of my dependent services
stopped working. It took me quite a while to figure out the underlying issue,
but I got one of them back up and running by simply adding the new R3
intermediate certificate to the trust store of a non-Java service (actually, it
was Apache httpd mod_authz_ldap). That was fun tracking-down, but I digress.
The other service is JasperReports Server, which uses Spring Security for
authentication against our LDAPS database. It's running on Tomcat, and here is
the important part (IMO) of the command-line of the running
process:
-Djavax.net.ssl.trustStrore=conf/truststore.jks
-Djavax.net.ssl.trustStrorePassword=[the password]
The "conf" directory refers to $CATALINA_BASE/conf.
Dumping the existing conf/truststore.jks file reveals the contents:
Alias name: letsencrypt
Creation date: Dec 12, 2016
Entry type: trustedCertEntry
Owner: CN=Let's Encrypt Authority X3, O=Let's Encrypt, C=US
Issuer: CN=DST Root CA X3, O=Digital Signature Trust Co.
Serial number: a014142015385736a0b85eca708 Valid from: Thu Mar 17 12:40:46
EDT 2016 until: Wed Mar 17 12:40:46 EDT 2021
Nice. So just add the new certificate to the trust store and restart the
service, right?
$ keytool -importcert -alias 'letsencrypt2020' -keystore conf/truststore.jks
Enter keystore password:

tomcat 9 fails when requesting a new URL
I'm working on developing a web page using Tomcat 9 as the local server. My web page comes up and when I submit my page for processing, the tomcat server crashes. Interestingly, when I run the same sequence in Eclipse, everything works fine. Anyway, I looked at the logs directory and I see some suspicious sections, but nothing that points directly back to source code causing the problem. I cleared the log directory and re-ran my process and I am attaching a compressed tar file of the log directory. I'm wondering if anyone can see any indication that Tomcat 9 is not configured properly. I apologize for sending the entire directory, but it is fairly small and I want to make the entire log available. The most likely error point is the "java.io.StreamCorruptedException: invalid type code: 00" in the catalina.2021-01-10.log file. Can my process or environment be the root cause of this?

RE: jdbc connction pool issues [EXTERNAL]
Hi Shawn, No, I don't think that maxActive means that it's defining the maximum number of connections for the pool, I think it's strictly referring to the "[ .. ] maximum number of *active connections* that can be allocated from this pool at the same time. [ .. ]" (emphasis mine on active connections) Here is the doc that I've been referring to - sorry for not linking it earlier: https://tomcat.apache.org/tomcat-9.0-doc/jdbc-pool.html On those other Tomcat servers is there a initialSize defined?

RE: jdbc connction pool issues [EXTERNAL]
Hi Shawn, I can't speak to that monitoring tool or why it reports that way. I do see what you're saying though - I would expect the error message to be something like: >>name="jdbc/DataSource",type=DataSource has reached 80% limit. >>Current pool size [8, Max pool size [10] However, it could be that the number of maxActive connections at the time was 8 and they simply labeled it incorrectly. From my perspective it seemed that if you're getting an alert at 80% pool size and the current pool size is 8 then you're probably looking for a default setting of 10 somewhere that isn't being set and initialSize seemed like a good candidate for that setting. Perhaps you might check your monitoring tool thresholds - I would have to think that 80% is setting off bells and whistles so you have time to act before your JVM blows up.

tomcat v 9.0 crashing in Eclipse IDE Version: 2020-09 (4.17.0)
I am trying to run Tomcat v 9.0 in Eclipse on a linux PC and the server is crashing before if fully starts up. At this point, I do not consider this a user error, but possibly my configuration of Eclipse is a bad one. But even if it is, there should be error message not a crash with a stack trace. For now, I am simply including the error file showing the stack trace.

tomcat 9.0 cache warning errors
While writing this post, I managed to fix my own problem with help from the internet. The solution is for anyone running tomcat v 9.0 inside eclipse. Tomcat v9.0 in eclipse gave me a large number of cache warning errors and eventually crashed. While verifying the problem, I discovered a fix discussed at the following url: https://stackoverflow.com/questions/14771710/how-to-solve-javax-servlet-servletexception-java-lang-unsupportedclassversioner That site recommended adding the following line to the tomcat path .../config/context.xml. | I added that line to context.xml and after several iterations of trying, the |||cacheMaxSize value was 60 (i.e. 600M-bytes in size). The website I am working on only contains 22 M-bytes so cache size should not have been an issue, but the warnings kept coming. Then I thought, maybe Eclipse has its own version of tomcat 9.0 and sure enough I found there is a tomcat v 9.0 sub-directory in eclipse/workspace/Servers directory. I added the 'Resources' line shown above to the the conf/context.xml file in the eclipse tomcat v 9.0 sub-directory and that fixed my problem. |So the 2 step fix for cache error messages is: 1) locate the correct version of tomcat in your eclipse workspace 2) add "|||" to your context.xml file. I will update the stackoverflow.com URL with a comment. I'm not sure if this is worth mentioning anywhere in the tomcat documentation. I will leave that to others.|| -- Jim Anderson

Can you confirm that port 443 is actually listening when you start Tomcat? Are there any errors in the catalina.out log? Ports lower than 1024 are considered privileged ports and only root can manage processes that use those ports. There are some workarounds where you can use software like authbind to have a non-root user do it instead but it takes some extra tinkering. There are also folks that run Tomcat on 8443 and then configure iptables to forward port 443 to 8443. There are a few different ways to accomplish what you want to do - have you researched any of these solutions? Jim

Upgrading to tomcat 8.5.41
We are currently running 8.5.32 on Server 2012r2. I went to use the upgrade tool before downloading 8.5.41 and the instructions say "If there are no differences you will see an error page." http://tomcat.apache.org/migration-85.html#Upgrading_8.5.x When I check for any differences, even going back to 8.5.0 compared to 8.5.41, I get a "Forbidden You don't have permission to access /repos/asf on this server".

Updating tomcat Windows 2012r2
I'm on 8.5.6, and just downloaded 8.5.32 yesterday. On my test machine I stopped the service, copied in the core files, copied over my server.xml, web.xml, and the hosted application and it seems to work just fine, and thinks it's running 8.5.32 when I look at the logs. Is this correct for updating tomcat? I feel like I'm missing something. jim - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
RE: setting packetSize for ajp connector in embedded tomcat via commandline system property
Hi Chris, > What led you to believe that there was a particular system property that had > any effect? Because I've seen other properties such as: server.tomcat.connector.max-post-size= server.max-http-header-size=XX server.use-forward-headers=true server.ajp.port= And I guess honestly, I was hoping that perhaps there was some standard that if it's a configurable option in an AJP Connector stanza, then there's a corresponding command line system property that can be used instead. This line of thinking of course would require that Spring Boot was using some "official" embedded Tomcat code that had a zillion options all ready to be used but as I read through your response, it's dawning on me that my line of thinking is completely off. That it's really up to the developer of the spring boot app I'm using to put into their code whatever options or settings that they need tomcat to use. If their code doesn’t use AJP or do anything with server.ajp.port, then no matter how hard I try, I'll never get an AJP connector to work. I think I get it now. My apologies, this is my first stint doing sysadmin work with embed and I've been treating it like a full blown Tomcat instance that comes with everything turned off, but still included, thinking I need to supply all these different arguments to turn stuff on. It's more like it's available but not included - the developer needs to supply the code to turn on the tomcat feature. Have I got it right now?

setting packetSize for ajp connector in embedded tomcat via commandline system property
Hello, I'm trying to set packetSize for an embedded Tomcat 8.5.4 AJP connector using a command line property and I am failing. Does anyone know what the correct property might be? These are some settings that I know which work that I've found in the Spring Boot Reference guide but that's not a complete reference. I'm thinking it should be something like -Dserver.tomcat.connector.packet-size=65536 Or something close to that - but there's no consistency that I've been able to find in naming conventions at the server or server.tomcat or server.tomcat.connector level. And after many hours of guessing I'm turning to you all in hopes that someone may know the correct setting. Can anyone provide the correct syntax? Or is packetSize for the AJP connector not even supported through command line for embedded Tomcat? Thanks! - Jim

Syntax change in Set-Cookie header?
Hi everyone, After a recent upgrade from Tomcat 8.0.28 to 8.5.11, I've noticed a syntax change in the Set-Cookie header generated by Tomcat, and I was hoping to confirm whether this is intentional or if I'm doing something incorrectly. The background: After upgrading Tomcat, some automated tests started failing. These tests use an Apache CXF client to make requests to a service running inside Tomcat, and then make various assertions on the value of the Set-Cookie header returned from from the service. The root cause of the failure appears to be a change in the syntax used for the Set-Cookie header which resulted in parsing failures in the client. The header that's generated by Tomcat 8.0.28 looks like: Set-Cookie: cookie_name=value; Path=/ With 8.5.11, it looks like: Set-Cookie: cookie_name=value;path=/ Note the missing space after the semicolon and the change from "Path" to "path". After some digging around, I saw that the new Rfc6265CookieProcessor was changed to be the default cookie processor. When I followed instructions [1] to change back to the old processor, the original behavior was restored and my tests pass again. Is this expected behavior? I see that RFC 6265 specifies [2] that there must be a space between the semicolon and "path", and that it should be "Path" with the first letter uppercased. Taking a look at the Rfc6265CookieProcessor source code (the generateHeader method, specifically), the lack of space and lower case p appear to be intentional, yet don't seem to conform to the RFC the class is targeting. I am sure I must be missing something since this is the new default and this is such a common behavior, but I've dug around for a while and can't find another explanation. Thanks in advance for your time and help!

The parts that are relevant to your certificate are in the section here: https://tomcat.apache.org/tomcat-8.5-doc/config/http.html#SSL_Support_-_SSLHostConfig but scroll up slightly to get the instructions on how to use this subsection. jim On 12/1/2016 1:26 PM, Bartlett, Todd wrote: Thanks for your reply, unfortunately I know very little about Tomcat beyond the server.xml config below.

Best practices around Kerberos ticket management & Tomcat instances? [Linux]
Hello, This is my first experience using Kerberos and lucky me it's with Tomcat on Linux. We're only using it to access an MSSQL database for now - no single sign-on (yet). So far the testing has been done on one server and it's been pretty successful. We're now looking to enable this functionality on the other two servers that make up this environment. My questions are mostly around best practices when it comes to managing tickets with multiple tomcat instances for a single app so I'll just get to it: - We will have three tomcat instances on three different linux servers all running the same application that will be connecting to the same MSSQL instances. Here are the two options I've come up with that make the most sense right now - 1. Have each Tomcat instance use the same SPN and get tickets on their own respective servers. The means that at any given time there would be three active tickets for the same SPN but I would have each tomcat instance doing kinits and kdestroys as the app is started or stopped. Or 2. I need to create a new SPN (and new AD accounts?) for each tomcat instance accessing the MSSQL database and each tomcat instance would be doing kinits and kdestroys with its own ticket. I'm leaning towards option #1 but perhaps someone has another option or can lend some thoughts as to which way I should proceed? - On each server, we need to go through a process that requests a ticket when tomcat starts, uses the ticket as long as the JVM is running and then destroys the ticket when the JVM is stopped. I'm thinking that I modify the tomcat startup script in /etc/init.d so that when the specific tomcat option is called the following things happen: start:: - kdestroy is called to clear any existing tickets in the tomcat ticket cache (cache is in custom location w/ custom filename) - kinit is called to request a renewable ticket - lets say 14 days - tomcat process starts as normal stop:: - tomcat process stops as normal - kdestroy is called to clear any existing tickets in the tomcat ticket cache (cache is in custom location w/ custom filename) Once the ticket has been requested, I would have a crontab job go out and do renewals every 12 hours - noon and midnight perhaps? Does a ticket renewal in the middle of the day become too risky with the application running in production? Then once a week, I would have the application stopped for DB re-indexing, other maintenance, etc. We should never get to the point where the JVM is running for 2 weeks and then causes a problem when the ticket expires. Would these align with best practices that others have done or seen in similar scenarios? Do the ticket lifespans and renewal timeframes make sense or should they be less often / more often? I really appreciate any feedback or thoughts on this - thanks! - Jim
If there a security hardened / production ready binary distribution?
Hi all. Sorry if this has already been answered, but I couldn't find it. I'm looking at using tomcat in a docker container and I was wondering why there isn't a binary distribution that has most / all of the steps already done from the security how to? https://tomcat.apache.org/tomcat-7.0-doc/security-howto.html I understand that there wouldn't be a true one size fits all, but I rather than get everyone to try to follow the same basic steps I thought that they would be done upstream in the project. If there's a reason why, I'm curious to learn what it is. I've also opened a ticket with the official docker tomcat image project for a tomcat that has this done. https://github.com/docker-library/tomcat/issues/14 Thanks for your time. Jim

I was curious why the error did not show up in my firefox browser console, so I removed my fix and re-ran my application with the error in it. Sure enough, the error did not show up on the console. One thing I am going to do, before going back to my main stream work is write up a document for myself on how to debug my current environment.

Re: My problem: I cannot successfully get or set a session attribute from a JSP file.
David, I have to question your response. In the past, I have made errors in the serverside JSP file and the console has identified errors for me to the point were I have become dependent this feedback. I understand the separation of the client side vs the server side, (and I must confess that sometimes in the middle of debugging, I forget that it is there), but my assumption has been that when the JSP code is compiled by the tomcat environment, it gets sent errors back through the Firefox API that allows the errors to be displayed in the console. I don't know the Firefox API, but I can believe it has hooks in the brower code that allows an application such as Tomcat to post information into the console. If fact, I would expect the browser console to have that kind of hook. Jim On 12/08/2014 03:54 PM, David kerber wrote: On 12/8/2014 3:49 PM, Jim Anderson wrote: Resolved!

installing tomcat7-admin --- I have not /etc/tomcat7 directory
I am running on crunchbang Linux, a derivative of Debian Linux, and I use apt-get to install most packages. However, I am in the process of upgrading from tomcat6 to tomcat7 and I have a problem because tomcat7 is not available for download with the crunchbang distribution. When tomcat6-admin was installed with apt-get, the /etc/tomcat6 directory got populated for me. I downloaded tomcat7 as a compressed tar file from apache and installed it. The Tomcat7 daemon is running. But right now, non of my web applications can be accessed from my browser and there is no /etc/tomcat7 directory to control the local configuration. I will look at the web application failure at a later time. For now, I would like to get the tomcat web manager running but I need a /etc/tomcat7 directory set up properly. It looks like it should be created when the tomcat7-admin package is installed. But I cannot find any documentation about installing tomcat7-admin. I have scanned through the tomcat7 doc website and have not been able to find the installation instructions I'm looking for. Can someone either point me to the instructions I would need to install tomcat7-admin? Regards, Jim Anderson
Re: installing tomcat7-admin --- I have not /etc/tomcat7 directory
Chuck and Hassan, Thank you for your replies. Obviously, I did not realize that /etc/tomcat6 is an artifact of the crunchbang distribution. However, I actually did use the standard tomcat7 distribution prior to sending in my help request. I have now read the directions and they were very helpful. I got tomcat7 working with no trouble at all in a short amount of time. Lets just say I was misled by the tomcat6 distribution from Crunchbang. In some ways, I do not like some of their restructuring, but in all honesty, they do a great job of distribution and support. I love their version of Linux because they use the KISS (Keep It Simple Stupid!) principle. Anyway, you help not only resolved my tomcat7 problem. But now that I have tomcat7 working, my problems with Struts 2 in tomcat (struts 2 was crashing in my linux environment) is also resolved, so now I can get back to my software development. A big thanks to you and to Hassan for taking the time to help me out Regards, Jim On 07/12/2014 03:13 PM, Caldarale, Charles R wrote: From: Jim Anderson [mailto:jim_ander...@jjajava.com] Subject: installing tomcat7-admin --- I have not /etc/tomcat7 directory I have a problem because tomcat7 is not available for download with the crunchbang distribution. You would need to discuss on whatever support mechanism is available for crunchbang. When tomcat6-admin was installed with apt-get, the /etc/tomcat6 directory got populated for me. That is a characteristic of the particular repackaged Tomcat you were using, not of any standard Tomcat distribution. there is no /etc/tomcat7 directory to control the local configuration. No such directory exists in a standard Tomcat distribution. For now, I would like to get the tomcat web manager running but I need a /etc/tomcat7 directory set up properly. No, you don't need any such directory. You do need to look at the Tomcat manager documentation: http://tomcat.apache.org/tomcat-7.0-doc/manager-howto.html It looks like it should be created when the tomcat7-admin package is installed. Again, that is not part of a standard Tomcat distribution. But I cannot find any documentation about installing tomcat7-admin. Because it's an aspect of the 3rd-party repackaging of Tomcat, not of a real Tomcat. The 3rd-party repackaged versions tend to scatter files all over the place, disregarding the proper Tomcat setup. Stick with the standard Tomcat from tomcat.apache.org, read the docs for the level you chose, and have a look at the FAQ/Wiki. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

Re: Severe performance issues on images
Hi Christopher, Thank you for your insights and sorry for a late reply. This specific issue seemed do be because of limited bandwidth at the data centre and it had now been fixed. We are having some other problem as well, but these seem to come from inefficient modules at the moment and we are investigating at full pace. What is the JkMount directive(s) that you are trying to undo with JkUnMount? JkMount /* customer Whenever you turn off /Tomcat/ they get fast again? Do you just have to stop Tomcat or do you have to de-configure it in httpd.conf? Only stopping Tomcat is required. This would correspond with the bandwidth issue. Wait, you have a server with 64GiB of RAM? Cool. And it serves images for a living? Weird. It is both cool and weird. :P The reason for 64Gb is basically that when things break down, more ram and cpu delays the problem. We are looking for ways to reduce memory usage. Up. Grade. We are looking into it, but 7.0.26 seems to be associated with this Ubuntu version. Is it a huge difference? I really don't want to rock this boat any more that absolutely necessary.

Why wouldn't you be interested in getting these logs? They are requests being handled by your web server. They require (a small amount of) time and resources to process, and indicate that your lb is still reaching-out to determine the status of the app server. My recommendation would be to leave those logs in there (they accurately describe a real request) and filter them out if you want to do some kind of analytics against your log files and consider those OPTIONS requests to be noise. I have had one case where I wanted to get rid of those requests too, so I can understand the OP. But I have to admint I had a scary feeling about it.

It's not that simple: if you want to use condition, then you have a write a Valve (can't be a Filter, since it must run *before* the AccessLogValve) that tests the request and sets a request attribute that will then trigger this condition. That is not true, you can use a filter, since the logging will happen *after* the request and can and will check the request attribute then. Thanks for pointing that out. After I had sent my message, I realized that and decided not to post a followup after reading yours. - -chris Thank you all for your responses. It looks like I'll just have to put up with these messages. There seems to be no easy way to filter them out. Actually, based on earlier responses and on the URLrewrite filter (http://http://tuckey.org/urlrewrite/), there may be a solution after all, which does not involve additional Java programming, as long as you are willing to do some research by yourself. (Short intro : the URLrewrite filter is a bit of a workhorse, simioar to mod_rewrite for Apache httpd, and which can do a multitude of things when it comes to filter/modify HTTP requests in Tomcat) First, get the URLrewrite User's Manual at http://urlrewritefilter.googlecode.com/svn/trunk/src/doc/manual/4.0/index.html and then search for : condition element (see method and remote-addr) and set element (see request (default)) : The same as request.setAttribute([name], [value]) (note, name must be set). So, the requests that you want to not log look like this : 10.122.32.4 - - [16/Sep/2013:17:12:49 +1000] OPTIONS / HTTP/1.0 200 - 10.122.32.4 - - [16/Sep/2013:17:12:51 +1000] and thus they address the / (default) webapp, originate from the client IP 10.122.32.4, and have the method OPTIONS. And on the other hand, the AccessLogValve has an attribute which allows you to specify that if the request has an attribute (e.g.) nolog set, it will not be logged. So, by configuring your ROOT (default) webapp to include the URLrewrite filter, and configuring this filter properly, you should be able to attain your goal

Hi,
I'm also interested in a method to filter those OPTIONS.
With the same setup, I basically created my own AccessLogValve wich
does the filtering, something like :
/**

*/
@Override
public void log(Request request, Response response, long time) {

At the moment I'm getting one of these every 2seconds, but I haven't enabled
the second load balancer for HA purposes yet.
When I do that, I'll be getting twice as many hits of this type.
This is going to result in rather large log files full of noise that I'm not
interested in.
I've been trying to work out how to filter these out.
Basically I don't want to log anything that is using the HTTP OPTIONS
Request
Method, but still want to log anything else that Tomcat usually logs.
I have a feeling it will come down to modifying the following entry in the
/etc/tomcat7/server.xml file:
Valve className=org.apache.catalina.valves.AccessLogValve
directory=logs
prefix=localhost_access_log. suffix=.txt
pattern=%h %l %u %t quot;%rquot; %s %b /
Specifically adding the condition=VALUE attribute, but I have no idea
what to set
VALUE to.
The docs say that if ServletRequest.getAttribute(VALUE) returns null for
the
attribute defined in condition, then the item will be logged.
Is there an ServletRequest attribute that is null when the http request
method
is not using OPTIONS?
Or am I completely off track and there is a different way to filter these
access log messages?
Regards,

Hi André.
I'm not sure I follow what you're saying.
I don't want an IP filter, since I need the HTTP OPTIONS check from the load
balancers to reach the Tomcat servers and a response to come back, or else the
load balancers will think the tomcat instance is unhealthy.
I just don't want that check to be logged at all.
Although there are other things that use the HTTP OPTIONS check, these load
balancers are only exposed to internal traffic requesting specific servlets
from the Tomcat servers, and so there won't be anything else of interest using
the HTTP OPTIONS request methods to the Tomcat servers.
Hi Cédric.
What you posted is some Java code that needs to be compiled and then the
resulting class file put somewhere where Tomcat can find it right?
Is it only partial code where 'exclude' was some sort of pre-populated
comma separated string?
Just checking as it doesn't look like anything that you can put direct into a
Tomcat configuration file to me.
Or is it?
Regards,
Jim Barber

Why wouldn't you be interested in getting these logs? They are requests being handled by your web server.

Re: TC 6.0.2*: Dynamically-compiled jsps/tags not being loaded
Thanks for the question -- I worded that part awkwardly. Our project has a root-level /src directory with the web app's Java files, and a root-level /war directory with the exploded non-Java files (static assets, JSPs, etc.). When developing, Eclipse compiles the /src directory into the /war/WEB-INF/classes directory, and then copies any changed files from /war into its embedded Tomcat instance. When we switch Git branches, that could change the .jsp/.tag files inside the /war directory, but depending on the branch, those changed files might have an earlier modified-timestamp than the .jsp/.tag files that have already been copied over to the embedded Tomcat's exploded webapp directory. So my thought was that those files would not, then, be recompiled, and so at runtime, Tomcat would be using the older versions of those files that are cached in Tomcat's /work directory. I think that theory is countered, however, by my colleague's claim that she clears out /work before deploying a new branch, and also my own experience wherein I watched Tomcat re-compile the .tag file into the /work directory, yet still claim the tag's class cannot be resolved. But to clarify: no part of Tomcat itself, including /work, is kept under version control. -- Jim On 11/20/12 2:18 AM, Pid * wrote: On 19 Nov 2012, at 23:58, Jim open...@gmail.com wrote: Hello!

Re: TC 6.0.2*: Dynamically-compiled jsps/tags not being loaded
What I'm getting at is this: your release process should produce a .war (or exploded directory) that is copied to Tomcat and that Tomcat should not be reading any part of the app from the /war directory - a source controlled directory. Right: we produce an exploded directory which is then copied to Tomcat. The exploded /war directory in our project is copied into $CATALINA_HOME/webapps/[name of app]. All of Tomcat, including the /work and /webapps directories, is separate from our source-controlled project. To clarify one thing: the JSPs /are/ being compiled, and recompiled. I will see the classfile for the JSP/tag appear in Tomcat's /work directory, but Tomcat claims it can't find it. If I remove the .class file in the /work directory, and re-visit the JSP, Tomcat will re-compile the .class file, but the page will still fail to load with the same error about not being able to resolve the class. That latter behavior makes me think that Git/timestamps are a red herring; my problem seems to be that the compilation occurs correctly, but that the classes are sometimes not loaded into the classloader.

I then restarted Tomcat, refreshed the page in my browser, and all is well. I've also seen this happen regularly for my Windows-using colleagues, as well as in a non-Eclipse Linux-based 6.0.29 instance, and (hearsay) a colleague reported it happening in his Tomcat 7. Thinking it was a runtime race condition, we also tried telling Tomcat to load the JSP on startup via the web.xml, and while we did see the .java and .class files being created on startup, we still ran into the issue. We haven't yet tried pre-compiling our JSPs/TAGs before starting Tomcat -- but that shouldn't be necessary, right? I'd love some advice/insight in how I might investigate this further, or if there's a gotcha I might be running into. It feels like a race condition in the classloader, but I don't want to submit a bug report without a reliable test case, of course. Since we can't reliably recreate the situation, I'm having trouble putting that together. This seems to happen more often for me when I'm switching between substantially-different Git branches, so I thought it might have to do with the /work directory having older versions of the JSPs/TAGs, but one of my colleagues claims to clean her /work directory every time she switches branches, and before starting Tomcat, and still getting the issue.

Problem with JAASMemoryLoginModule?
, Principal userPrincipal, LoginContext loginContext) {
super();
this.name = name;
this.password = password;
this.userPrincipal = userPrincipal;

this.roles = new String[roles.size()];
this.roles = roles.toArray(this.roles);
if (this.roles.length 0)
Arrays.sort(this.roles);

This seems like it could be a bug, but given that I am new to JAAS on
Tomcat, I may just be doing something wrong. Any JAAS/Tomcat experts out
there able to point me in the right direction?

problems installing app on tomcat v.7.0.26
Greetings — I'm running into errors installing a Java app called GeoServer (latest stable v2.1.4) on my Tomcat server at sge.lclark.edu:8080 (Tomcat v.7.0.26, JVM v.1.6.0_20-b20). I downloaded the .war.zip file, expanded it, and uploaded the .war file into a root-level directory (/geoserver) in Tomcat's webapps folder. Then, using the Tomcat manager, I tried both clicking Start for this directory, and used the Deploy menu below. The Deploy option results in Tomcat error Application already exists at path, and the Start option results in Tomcat error Application at context path /geoserver could not be started. A full catalina.log output for the latter error is below. I'm no Tomcat expert, but I have successfully installed one other app on this Tomcat server so don't expect the below to be purely a Tomcat issue…maybe it is? Would sure appreciate help; thanks.

Source jar for tomcat-dbcp?
I have a problem I need to debug by stepping into tomcat-dbcp (6.0.35). I tried downloading the Apache commons-dbcp source but it seems the version in Tomcat has the classes in different packages, so I can't get Eclipse to recognize the source. I've searched the following areas: * the tomcat source zip (apache-tomcat-6.0.35-src.zip) -- it does not contain the dbcp source * archive.apache.org/dist/tomcat/tomcat-6 * maven-central; it has source jars for tomcat 7, but none for tomcat 6. * svn.apache.org/repos/asf/tomcat/tc6.0.x/tags/TOMCAT_6_0_35/java -- this does not contain the dbcp sources either * svn.apache.org/repos/asf/tomcat/tags/JDBC_POOL_1_1_0_1/ -- This looked promising, but on examination it does not seem to contain the source for the library in 6.0.35 The tomcat-dbcp.jar that came with 6.0.35 contains the following packages: org.apache.tomcat.dbcp.collections org.apache.tomcat.dbcp.dbcp org.apache.tomcat.dbcp.dbcp.cpdsadapter org.apache.tomcat.dbcp.datasources org.apache.tomcat.dbcp.jocl org.apache.tomcat.dbcp.pool org.apache.tomcat.dbcp.pool.impl So, where can I find the source for tomcat-dbcp 6.0.35?

tomcat6w.exe -- 32bit and 64bit versions identical?
I am in an environment where I deploy tomcat via a script. Rather than keep two entire copies of Tomcat for 32- and 64-bit systems I have the complete 32-bit download plus the 64-bit tomcat6*.exe files. I'm upgrading from 6.0.20 to 6.0.35 and my usual procedure is to diff the 32- and 64-bit versions, which in the past has found only those differences (and tcnative-1.dll). This time, when diffing apache-tomcat-6.0.35-windows-x64 with apache-tomcat-6.0.35-windows-x86, I get only tomcat6.exe as different. The two versions of tomcat6w.exe are identical. Is this correct?

If VirtualWebappLoader is updated to trim each value in virtualClasspath, then that example could be wrapped into several lines. That seems like a very reasonable thing to do, as long as it's just trimming-off leading and trailing whitespace. I noticed while I was reading those two examples that we have two separate path separators in the same example: virtualClasspath uses semi-colons (aka win32-style path separators) and extraResourcePaths uses commas. Maybe we should try for some consistency :) VirtualWebappLoader already trims the spaces, so I fixed the docs. extraResourcePaths does not trim, so it needs more work. I agree that ';' is better there. My plan is to check if the path contains semicolon ';' and if it does then go with ; as separator. Otherwise fall back to the current comma ,.

I always like to avoid violating the principle of least surprise. minSpareThreads as a name implies to me that those spares are /always/ available, even immediately after startup. Chris - If you look in org.apache.catalina.core.StandardThreadExecutor, you will see that it is using a ThreadPoolExecutor. setMinSpareThreads() calls setCorePoolSize() in the ThreadPoolExecutor. If you read the javadoc for ThreadPoolExecutor, specifically the subsections labeled Core and maximum pool sizes and On-demand construction, you will see that the threads are created on demand unless you use prestartCoreThread()/prestartAllCoreThreads(), which Tomcat does not. So, although it may seem surprising or even counterintuitive, all 150 will not be fired up on startup. Perhaps we could add a separate attribute on the Executor (e.g. startThreads)? Then Tomcat would have a paradigm similar to httpd's Start(Servers|Threads) and MinSpare(Servers|Threads). Any interest in such an attribute? It would be fairly simple to roll a patch for it... - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

It returns 0 in case of timeout (two seconds in this case).
Try to change

We have nothing against these projects, we just had a different preference for this tool. Needs to be improved We are aware that it needs some features, such as: - #1 Documentation - Easier navigation - Bash-style auto completion (if accomplished, could also benefit the Jython project) - Compile Jython code to Java classes We are working on getting these problems addressed. To our knowledge it works without issue with Jython 2.5.1+. (http://sourceforge.net/projects/jython/files/) What we'd appreciate Feel free to reply back with bugs and enhancement requests.

JSESSIONID being lost
I'm hoping someone may have some insight into a difficult problem we are having. We have a situation where the JSESSIONID seems to get lost somewhere in a users transaction - the result is they get kicked back to the applications login page (no sessionid so the app thinks they haven't logged in). Our current setup is two hardware load balancers (layer 4) in front of two Apache servers (2.2.14) which sit in front of two tomcat servers (6.0.20). The hardware load balancers load balance apache and apache load balances tomcat using AJP via mod_proxy. Apache and Tomcat are running on RHEL4 32-bit. The JVM is 1.6. This issue first popped up when we moved to the above architecture - previously we had no hardware load balancers and only one apache server balancing two tomcat servers (still with AJP via mod_proxy). Initial thoughts were that it had something to do with either the 2nd apache server or the load balancers. One way we have made this better (but not fixed) was to turn off one of the tomcat servers so that requests could only go to one place - we thought that the users session was being sent to the other tomcat server even though we were using sticky sessions. This was our temporary fix until we could implement clustering, but today we found that users were still being kicked back to the login page even with only one tomcat server running. In the interim we have turned off one of the apache servers to see if that helps (so two hardware load balancers, one apache server and one tomcat server). This problem is intermittent and almost impossible to reproduce, but it does seem to happen more under heavy load. Any insight would be very much appreciated. If it would help I can post our apache and tomcat configurations. Thanks in advance.
Re: JSP Page hangs... clues?
Can you truss/strace Tomcat, or watch the network traffic between MySQL and Tomcat? Comparing captures from those tools between successul and hung page generation might show what the issue is, or at least suggest other areas to look at. On Wed, Feb 10, 2010 at 2:53 PM, Jordan Michaels jor...@viviotech.net wrote: We have an interesting situation and I'm wondering if anyone has any ideas on where we could look for possible solutions. We have a JSP page that performs a large mysql query of product titles (just the names). The list is then spit out on the page with drill-down links. Pretty simple really. The problem is that just after a tomcat restart, the first and occasionally the second and third requests will process all the way just fine, but most subsequent requests will hang on a random record. Occasionally one will go all the way through, but most will hang. Let me clarify, we restart tomcat, hit the page, and the page loads fine. We hit refresh once or twice, and the page will fail to load fully. The page will hang after a random product title and just stop responding. You can click on any other page on the site, but this one page with the large product listing query hangs in random spots. We've studied this intently. The server this is running on is a CentOS 4, 32-bit box with 1.5 GB RAM, Apache 2, and mod_jk. Our first thought was memory issues. We increased Tomcat's memory using the setenv.sh file, which now contains the following line: JAVA_OPTS=-Xms128m -Xmx1024m -Xss256m -XX:MaxPermSize=256m ; export JAVA_OPTS We've verified that the settings are in place by using the ps ax command and making sure the java process includes the updated settings. Unfortunately, this seems to have no effect at all. We then reviewed the logs: catalina.out, mod_jk.log, and apache's error_log, among others. We monitored these logs using tail so we could see if any errors were thrown as we hit the page. No errors were thrown if the request went through good or it failed. The logs were completely quiet. We've updated Tomcat, mod_jk, the JVM, and the MySQL driver to the absolute latest versions available as of this writing. Does anyone have any clues as to where we might look for what is happening to make this one page hang? It still feels like a memory issue, but with nothing in the logs and no indicators other then the problem itself, we'd appreciate any suggestions on what to look for at this point.

}
}

Host host = (Host) ServerFactory.getServer().findService(

mapper.addHost(name, aliases, objectName);
host.addContainerListener(this);
if(log.isDebugEnabled())
log.debug(sm.getString

}
}
Is this change to fix an issue ? Or Tomcat6.x totally change the host name
looking up mechanism .
Could you also point to me where can I find the Tomcat6.x document about
difference with Tomcat5.x if there is ? for example architecture , execution
etc.
Thanks in advance .

and went through a number of iterations. This was to
follow pid's suggestion.
Then started to respond to your suggestion about the tablib

I'm embarrassed to say this, since I know better. I really

I'm writing my first JSP program and I'm having a problem
with the c:when construct. I have a bean that contains
a property named 'midContent'. When the program segment
is entered, the bean, BFSInfo, has it's midContent property
set to 'page2'. The when tag test evaluates to false, yet
the code within the when tag is executed. Here is the
code segment:
18 c:choose
19 c:when test=${BFSInfo.midContent == 'page1'}
20 T/F = ${BFSInfo.midContent == 'page1'}
21 br/br
22 INFO EL is ${BFSInfo.midContent}
23 /c:when
24 ...
25 /c:choose
When run, the lines inside the 'when' construct print the
following on the web page:
31 T/F = false
32 INFO EL is page2
The test expression of line 19 is evaluated again at
line 20 and the result is 'false' as shown at line 31.
The output produced by line 22 is shown at
line 32 and confirms that the value of midContent is 'page2'.
Can someone explain why the code inside
the 'c:when' tag is executed when
the test on line 19 appears to be evaluating to false?
Thanks you in advance.

Re: JSP when tag question
David,
Thank you to 'pid' and yourself. I spent quite a few hours
going over the source HTML from Firefox and fixed some
problems (e.g. an tag with no closing tag) and fixed some
inefficient code. I was getting very inconsistent results
and went through a number of iterations. This was to
follow pid's suggestion.
Then started to respond to your suggestion about the tablib
libraries, etc. I have a number of jsp files using include
statements. Lo and behold, I did not have a taglib directive!
I'm embarrassed to say this, since I know better. I really
thought I had already done it, but I guess at the time I was
going to add the directive, I got distracted and failed to do it.
Having said that, I'm a bit surprised that there was not
error message generate by tomcat about seeing a reference
to c:choose and c:xxx with no definition available.
Thanks, again.

Re: Apache 2.2 to Tomcat 6 via proxy_ajp
On May 21, 2009, at 10:28 PM, J. Zimmerman wrote: I am just getting started with Tomcat and have been asked to take on the administration of our Tomcat servers at our college. I am not one of the developers, just the administrator. So far everything has gone pretty smoothly except for getting everything to run proxied via Apache (at least the way we would like it). Our requirement is for Tomcat to deliver the application through http://hostname:8080/appname and/or ajp://hostname:8009/appname. This happens by default and works well. However, we want end users to access the applications via port 443 or 80 and we are doing this via Apache. I can make this work via proxy_ajp and proxy_http so that something like http://hostname/appname works just fine. The wrench in the works is that we want to do virtual hosting through Apache and not have the appname appended to it. The Apache virtual hosted URL's will be the ones exposed to the public. For example if we developed an application called mycoolapp and we were deploying it at a website of the same name we would want the application to run at http://mycoolapp.com and not http://mycoolapp.com/mycoolapp. I have hacked together several different configs suggested through many different pieces of documentation and forums, but just can't seem to get it. Our setup is as follows. Server: Ubuntu 8.04 (all updates) Java: Latest JDK download from Sun Tomcat: Latest version 6 official download (configs are near defaults, I have revereted to the default server.xml) Apache: Latest version 2.2 via Ubuntu repositories. proxy_ajp, proxy_http, and rewrite enabled. If anyone has suggestions or a working example any help is greatly appreciated. ProxyPass / http://hostname:8080/mycoolapp -or- ProxyPass / ajp://hostname:8080/mycoolapp Assuming hostname:8080 is the Tomcat server No need for rewrite at all. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
acceptCount in Tomcat 5.x and 6.x?
Does the acceptCount setting that is part of the AJP connector in the server.xml file still exist in Tomcat 5.x and Tomcat 6.x? I see a lot of references to it in Tomcat 4.x, but I have not run across it in 5 or 6. We have this setting defined in our tomcat 6 installation, but I think it is a relic from some previous tomcat 4 configuration. Thanks
