RE: Redeploying war file kills context xml
Hi Jim,
thanks for your reply. Defining the context outside the war file solves some
issues, since we deploy the very same application to different server setups.
JNDI environment values are different on test and production machines, and
those are defined in the context.
Adding them to the war file under META-INF/context.xml would mean to produce
different war files for each deployment server. That's why it's annoying that
tomcat keeps deleting those manually edited files from it's configuration. Kind
regards,
- Christian

Realm defined within my webapp
I have several webapps I am trying to bring over from Resin that make use of various types of authentication that needs to live solely within my webapp (I may have multiple deployed instances of one with different versions, for example). I have attempted to add it to META-INF/context.xml in my web application, but I get a ClassNotFoundException when the app starts up. I would think it'd be common for applications to have code to perform their own authentication.

SSL handshake times out on Tomcat 5.5
Hi, although I've read all the docs and FAQs I could find, I can't get Tomcat 5.5.15 to do SSL on Windows with SUN JDK 1.5. I've imported the keys according to the docs, starting with the root CA cert and going all the way up until the cert that matches my key request. Then I've copied the keystore file "keystore" into CATALINA_HOME and configured Tomcat like such: All environment variables are set, JAVA_HOME plus CATALINA_HOME pointing to the right directories. When I start Tomcat, there's nothing special in the logs. Pointing a browser to https://localhost/ just times out. Doing the same using the OpenSSL tool gives me $ openssl s_client -connect localhost:443 -showcerts -state CONNECTED(0003) SSL_connect:before/connect initialization SSL_connect:SSLv2/v3 write client hello A 2644:error:140790E5:SSL routines:SSL23_WRITE:ssl handshake failure:s23_lib.c:188: Interesting point: Pointing the browser to http://localhost:443/ works. Since I don't find anything in the logs, I'm lost. Remaining issues are: 1) Should I import the server certificate under the alias "tomcat" oder the name of the host? There's different documentation about this. 2) Can I increase logging somehow, to see what's going on inside the SSL factory/connector? Any help is appreciated...

mod_jk failover loadbalancing doesn't recognize hung tomcat
Our application which runs on Apache HTTP Server 2.0.54, TOMCAT 5.0.28 with mod_jk 1.2.15 connector. In production while our application was running. Our application had a thread dead Lock hosing up all the users trying to connect our application. So started investigating the failover setup in mod_jk. I have two tomcat instances nodeA (active node ) and nodeB (failover node). When I run my test scenario of a thread dead lock on nodeA it doesn't seem to be failing over to nodeB. Instead whole site becomes inaccessible and based on the reply_timeout setting I have I receive a "Service Temporarily Unavailable" message. It is very critical for me to find an answer to this.

Problem configuring webapp with Tomcat 5.0.28 on RHE3
I've got a web application that runs succesfully on Win/Tomcat 5.0 and on RH/resin 2.x. I am pretty sure my problem is with the container configuration. I need to run several versions of the app and I'd like to do this using several different Tomcat instances, with different $CATALINA_BASE directories. (There is an Apache front-end but that isn't relevant yet.) I cannot seem to get the app to start. I have a directory set up as the CATALINA_BASE with the following content (I've left out a couple unrelated dirs for simplicity): base_dir apps myWebAppBaseDir (which contains WEB-INF and so forth) conf Catalina localhost ROOT.xml context.xml (the default that comes with Tomcat) server.xml web.xml (the default that comes with Tomcat) (other default files: catalina.properties, tomcat-users.xml, etc) logs temp webapps (empty) work I believe the necessary configuration is only in the server.xml and the ROOT.xml files, and the rest are OK to use the defaults. I've pasted the server.xml and ROOT.xml files below for reference. As you'll notice, I am attempting to run the app from a directory structure, not from a WAR file, and it is intended to run as the root application with no context path. Using the configuration I've currently got (below), I can start Tomcat and no errors show up in the logs, although the startup process my app normally goes through does not seem to occur (that is, the messages from it don't show up). If I try to hit a page on the server, I get an exception (below) that I can't find anywhere on Google nor in this list's archives. I tried configuring the app by placing the content of ROOT.xml into the element of server.xml, as is recommended AGAINST in the Tomcat docs. This produced the same exception. In all cases I start Tomcat using a script I wrote that sets JAVA_HOME and CATALINA_BASE and then calls CATALINA_HOME/bin/catalina.sh (full script below). Any ideas on what to do, or pointers to further research, are much appreciated!

I am currently working my way through all reported TC4 bugs (there is just one left if you ignore the enhancement requests) and back porting some connector enhancements that should make most of the connector options in 5.5.x available in 4.1.x. Once this is complete I intend to do a 4.1.32 release. Unless 4.1.32 has a major problem, it will almost certainly be security fixes only after that point.

Tomcat 5.5.16 Virtual Hosting Problem
Hi all: I have posted for help yesterday, but I think the post was poorly worded. So I am posting again. I am using Tomcat 5.5.16 (stand-alone) with JDK 5.0 on Windows XP and trying to setup virtual hosting (to start with two hosts + localhost). Once I start the tomcat server, three host folders are being created inside the work directory. As expected the localhost host has all the webapps that come with tomcat 5.5.16 installation like examples, etc. The work directory also has two other host folders test1.mymachine.com and test2.mymachine.com. There is a single root context for each of these hosts as shown below. The problem is along with a folder for these root contexts tomcat is also serving up all folders present in CATALINA_HOME as contexts. This is happening for both test1.mymachine.com and test2.mymachine.com. Any help is appreciated. Thanks in advance.

Re: running two instances of tomcat
Thanks, Chuck. I will take a closer look at RUNNING.txt. However, i still think there is something else causing our problems.. We installed two copies of the tomcat code, one running at root, and the other running as a regular user. Now, even if the ports were conflicting, it would prevent one instance from being launched, instead of killing another instance, would it? At one time when i was playing with it on a testing platform (also linux), the launching of the 2nd instance of tomcat 5.5 even killed a running tomcat 4.1.31!

caldav implementation in webdavServlet
Goog day, my name is George and Im student of IT, and I should create calendar server application suporting CalDAV protocol (as an extension to WebDAV to publish calendaring data). And I would like to ask, about implementation. I write it in java (servlet application working on tomcat server), but the problem is, that I have not found how to extend WebDAV servlet, to support CalDAV extension like MKCALENDAR, REPORT or other CalDAV requests? I tryed to find it myself, looking to many documentations or Tomcat's FAQ but I have't found, how to implement it. So, If you know, how to work with servlet container or how to expand WebdavServlet to make some interface to recognize CalDAV requests or if you know about some useful links I would be very grateful to you. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: robust Failover, mod_jk
Our application which runs on Apache HTTP Server 2.0.54, TOMCAT 5.0.28 with mod_jk 1.2.15 connector. In production while our application was running.

RE: return (HexUtils.convert(md.digest())) in RealmBase
Then maybe I'm misunderstanding something. But I can guarantee that MessageDigest.digest(), which returns an array of bytes, will NOT return an array of bytes every time that can be transmitted on a URL i.e. is a printable string. That's why it has to be encoded in some form, and two hex chars/bytes is the way this gets encoded. However, if you really do want to undo the encoding, simply reverse the logic of the encode() method in the MD5Encoder.java file. Alternatively, if you are just trying to authenticate something in your code, it may work to just run through the digest and encode steps yourself, then compare your end result with what the user sent. If they're the same, then they're authenticated, without you needing to "undo" anything.

Start Tomcat from a java client
Hi I would like to start Tomcat with axis2 from a java client. The use case is that there is a web service on a server. The clients can login on the server with the web service and the server. If all clients are ready the should work together without the service using webservices. So every client should provide a web service so the other clients can contact him. So it is necessary for every client to start the tomcat with axis2. Is this possible and if yes how? Thanks in advance. -- mfg Hans Sowa mailto:[EMAIL PROTECTED]
RE: Redeploying war file kills context xml
I am using Tomcat 5.5.15 w/ jdk1.5.0_06
In my webapp, I have created a context file in ${app.name}/META-INF/context.xml.
If Tomcat is running and I drop a new war file in the webapps dir, Tomcat reads
${app.name}/META-INF/context.xml and creates a new
${catalina.home}/conf/Catlina/${host.name}/${app.name}.xml This seems like the
correct way to do things (not a workaround), because your context is defined
and deployed with your webapp.
>From the Tomcat documentation

"A Context is what Tomcat calls a web application."
You could also define your context in server.xml, but this is discouraged in
the Tomcat docs.

Hi Kevin,
including a context.xml file in META-INF could cure the "disappearing context

would still be deleted but eventually restored. Any idea how I could configure
tomcat 5.5 to stop from deleting that file?
The other issue remaining is Tomcat trying to deploy an unfinished war file.

Connector Installation
Greetings from a new guy... I have Tomcat 5.5 running under FC3. I would like to install and configure the mod_jk connector, but I'm finding the documentation somewhat unclear. I know tomcat is working because I can display the samples via port 8080. The Apache web server is also installed and it is working on port 80. In the docs for the connector, it suggests that it is better to use the precompiled binaries instead of compiling them from source. I have no problem with that and I found the binaries for my platform, they are: jakarta-tomcat-connectors-jk-1.2.14-linux-sles9-x86_64-prefork.so and jakarta-tomcat-connectors-jk-1.2.14-linux-sles9-x86_64-worker.so The docs talk about a "mod_jk.so", which is not what I have (by name). Perhaps I'm supposed to rename one of these files to mod_jk.so ? If so, which one and what happens to the other one? The docs don't mention a pre-fork module (that I can see).

maximum number of threads for tomcat
Hi
We are desiging a push application to run with tomcat. Our servlet
interfaces to a backend and listens for async events, when the events
arrive,data is pushed to the browser. Browser opens a keep-alive
connection and shows the data received from servlet.
The doGet() method is like this
doGet(request, response){
initial_processing();
while(!Exit_Condition){
data = pipe.read() // this method will block for events
process(data);
out.flush();
}
out.close();
}
so this is one request - one thread model. we would like to know how
many threads can be churned on a desktop-type machine with 1 GB RAM
running linux 2.6.x. People say things like " on new kernels, high
number of threads should not be a problem" . on my machine default
thread-max is 32k. But i really do not know how to achieve such
numbers with tomcat.
when i do the arithmetic for my JVM, say , with 128k thread stack
size and 512 MB heap,i get only about 16 x 256 == 4k, so in reality
maybe 1k threads . how what am i missing here ? How can i tune the
maximum number of supported threads. Any pointers/resources. any-one
on this list running 4k-8k threads with tomcat ?
Thanks
Rajeev.

RE: return (HexUtils.convert(md.digest())) in RealmBase
I think this is the right answer: digest() returns a sequence of bytes. Depending on the values of the individual bytes, if you were to try and convert it to String, you can end up with non-printable characters, etc. I'm assuming that HexUtils.convert() turns each 4 bits of each byte into a hex character, so that you end up with a proper String representation of the digest that can be sent as part of a URL.

I think that may not be possible in our case. see one aspect of
keep-alive is you keep the pipe open because the same client can
request for more resources. But all such requests are alive for a
finite amount of time only ,so performance is always talked in terms
of through-put.
In our case,the servlet is interfacing to the back-end that sends
async events from time to time. So we really need to hold on to a
thread to receive notifications from the backend. The container spwans
a thread that enters the doGet() of servlet
doGet(){
initial_processing();
while(pipeOpen) {
data = pipe.read(); // will block for backend events
process(data);
outputStream.flush();
}
outputStream.close();
}
Now we can not return this thread to some pool, because I do not know
when the events will arive. And I need to keep the connection open to
push the data + need one thread to block on events.
So I need one thread to server one request. The difference from
previous case is , our processing of a request is not over in finite
time. we have to keep the same connection open.
I really donot see a way out w/o some support from the container itself.
Jetty has a feature called continuation that is supposed to solve this
issue.But for the moment, I want to try tomcat first. i want to see
how many threads i can support in such a scenario.
I will put a separate mail for that.

Look at this: http://tomcat.apache.org/whichversion.html The fact that this section http://tomcat.apache.org/whichversion.html#Apache%20Tomcat%204.x cantains twice the encouragement to upgrade to Tomcat 5.x whenever possible, you might want to consider following this advice.

Desupport for Tomcat 4?
Hello, Do you know when the tomcat development group plans on not releasing any new patches for Tomcat 4? Does this ever happen? If a bug is found in Tomcat 4 is it fixed in Tomcat 4 or are we forced to upgrade to Tomcat 5? Thank you for your time! ~ T r o y ~

Controlling contents of the localhost..log file
I've posed this question recently, but I am going to try to phrase it better, as I think last time it may have been poorly worded... My web application logs information to the localhost..log file. The information that is being logged is doing so correctly. However, here is my problem: In between every line of logging, an additional line is ADDED, which looks like the following: Mar 22, 2006 4:05:04 AM org.apache.catalina.core.ApplicationContext log Again, a line like this appears every other line in the localhost..log file. The lines that I want logged already include the date, so these lines are uneeded, and clutter up the log file quite a bit. My question: how do I get rid of these lines? I have already written my own java.util.logging.Formatter subclass, but this doesn't work. It appears that the formatter does not insert these lines. My Formatter only affected the lines that my webapp is logging, not the lines in question. Does someone know how to stop these extra lines from being logged? Thank you very much. -- View this message in context: http://www.nabble.com/Controlling-contents-of-the-localhost.%3Cdate%3E.log-file-t1324188.html#a3533134 Sent from the Tomcat - User forum at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

AppServer Comparison metrics

RE: apache(v2.0) front-end to jboss(v4.0.3)/tomcat5.5 webapp: context path prepend ?
You will probably want to set emptySessionPath to true
http://tomcat.apache.org/tomcat-5.5-doc/config/http.html
http://marc.theaimsgroup.com/?l=tomcat-user&m=114082698006999&w=2
Otherwise, the browser will send the cookie for /mywebapp as that is the
context which Tomcat will set JSESSIONID under.
Unless you don't need sessions.

Re: FarmWarDeployer instructions
Alle Tuesday 21 March 2006 18:05, Filip Hanik - Dev Lists ha scritto: Thank you Filip, please bear me one more time. I understand that only the "tomcat cluster master" should have a watchDir configured and watchEnabled set to true. The deployDir of all "tomcat cluster members" should point to the clustered appBase attribute; in case the element is defined on the , the directory should be the parent of the enclosed appBase attributes. Is this correct? The watchDir doesn't have anything to do with the appBase folders and can be exposed using any network filesystem (eg. CIFS, DAV or NFS) as long as the "tomcat cluster master" process can access it. Is this correct? In order to get the farm deployment running I do not have to download the tomcat-deployer package. Right?

connections not freed
Hi,
I have the following scenerio:
I'm running a jsp on tomcat 4.1.31 fronted by apache 2.0.54. This jsp uses a
tomcat jdbc pool connection with maxWait set to 1ms. At the moment the
database is screwed up because one of the filesystems on there has filled up
from an archive job.
Now when I run the jsp, the code stops after successfully getting the
datasource, and hangs indefintely on getConnection.
DataSource ds =
(DataSource)ctx.lookup("java:comp/env/jdbc/pol");
Connection conn = ds.getConnection();<= gets stuck
here
The browser also hangs, and when "maxClients" have logged onto the jsp,
apache doesn't take anymore connections even after the browser has been
shut.
Are there any timeouts or other settings on Apache/Tomcat I need to
configure to avoid this behaviour?
Thanks for any help.
Ed.
