2.0.4 connector source?
I thought there used to be link at the download site for the connector source to compile it, but all I see are a few binaries, which doesn't include a binary for what I need... http://jakarta.apache.org/site/binindex.cgi What happened to the source for the connectors? The only binaries available are: You'll find here Linux binaries for some of the major Linux distributions. * Fedora Core 1 - i386 - Apache 2.0.48 * Suse 9.0 - i386 - Apache 2.0.48 * Suse SLES 8.0 - ppc - Apache 2.0.48 What about RedHat 7/8/9 ? Should the fedora core binary be the same? Since compiling always seems better than using a binary for performance... where's the source?

RE: How to limit time for Connector threads?
A follow up to my previous mail.
You may try following snippet.
(I havn't tried it in a filter chain, so I'm not shure
if the exception reaches the filter)
InterruptTimer mTimer = new InterruptTimer(5000, 10);
mTimer.start();
try {
doChain() // Don't have the correct syntax at hand...
} catch (??InterruptedIOException?? ex) {
// Log what you think to be helpfull
}
mTimer.reset();
public class InterruptTimer extends Thread {
long oEndTime = 0;
int oSleepTime = 10;
Thread oStartingThread = Thread.currentThread();
Thread oRunningThread = null;
public InterruptTimer(int aLength, int aSleepTime) {
// Both times are in ms
oSleepTime = aSleepTime;
oEndTime = System.currentTimeMillis() + aLength;
}
public void run() {
oRunningThread = Thread.currentThread();
// Loop until the end time is reached or reset() was called.
while (System.currentTimeMillis() < oEndTime) {
try {
Thread.sleep(oSleepTime);
} catch (InterruptedIOException ex) {
}
}
if (oEndTime > 0) {
timeout();
}
}
public void reset() {
oEndTime = 0;
}
public void timeout() {
oStartingThread.interrupt();
}

RE: How to limit time for Connector threads?
I don't think that a debugger will help much in this case. A profiler might help, if you can reproduce the error in a test environment. (see below) Some ideas: - Use the access log to try to reproduce the error in a test environment. (AFAIK apache jmeter has the ability to create a test case from an access log) If you can reproduce the error, try to cut down the test case to the bare minimum that exposes the problem, then you might have luck with a profiler. - Write a servlet filter that logs the processing time for each request. - Extend the filter to interrupt the current thread if it takes to long and dump some data. > -Original Message- > From: rlipi [mailto:[EMAIL PROTECTED] > Sent: Friday, May 07, 2004 2:20 PM > To: 'Tomcat Users List' > Subject: RE: How to limit time for Connector threads? > > Maybe I have wrong idea about possibilities of debugging tools but I > think that it will not help.

Re: AW: How to limit time for Connector threads?
I'm wondering the same question. How do I setup tomcat to debug remotely? I found this doc: http://jakarta.apache.org/site/idedev-rdeclipse.html But in that page, it just assumes that you've got tomcat already setup to debug remotely, and it doesn't give a link anywhere on the page on how to do it. Could someone post the link?

You are coding in java. It is not possible to preemptively control a
Thread's execution cycle, in particular its termination. Trust me - check
it up - there are -no ways- to kill a Thread.
The reasons behind this are complex - but revolves around the problem of
leaving mutex-sections correctly ("monitors") when terminating a Thread.
Thus: code correct!
(The JSR 121 will fix this proble: http://jcp.org/en/jsr/detail?id=121.
The way they solve it, is that they in effect instantiate -an entirely new
JVM- for each thing that must be terminatable.)

Re: (newbie q) Connector vs running standalone Tomcat as root
The easier way is just leave tomcat listening on 8080 and add a port redirection rule using netfilter. - You just have to redirect incoming conections on port 80 to port 8080. - Add proxyPort="80" on the Connector tag in server.xml. Voila! You're done. Bytes DAC Barnet Wagman escribió: I'd like to hear people's opinions on the best way to have Tomcat accessible via standard ports (80 and 443).

Re: (newbie q) Connector vs running standalone Tomcat as root
commons daemon three machines two TAOLinux Tomcat 5.0.19 one RH9 Tomcat 4.1.29 Working fine. For overkill here is a write-up I did for another poster. How To set up RH9 and clones to start automatically and use port 80 with a non root user. If you have not created the user that you plan to specify in the script then do this first. Follow the directions under Tomcat setup located at: http://jakarta.apache.org/tomcat/tomcat-5.0-doc/setup.html This will create the executable needed by the script to start Tomcat. If you followed the directions you will find the file jsvc in $CATALINA_HOME/bin In the$CATALINA_HOME/bin/jsvc-src/native directory there is a file named Tomcat.sh or if you have the non Alpha package both a Tomcat.sh and Tomcat5.sh For this How To we are using TC5. I renamed my file to tomcat to match the other files in init.d #cp $CATALINA_HOME/bin/jsvc-src/native/Tomcat5.sh /etc/init.d/tomcat #cd /etc/init.d #vi tomcat OR your editor of choice Now edit the file to contain the proper environment setting for your machine. When you are done it will look something like this: # Adapt the following lines to your configuration JAVA_HOME=/tomcat/java CATALINA_HOME=/tomcat/tc5 DAEMON_HOME=/tomcat/tc5/bin TOMCAT_USER=tomcat TMP_DIR=/var/tmp CATALINA_OPTS= CLASSPATH=\ $JAVA_HOME/lib/tools.jar:\ $CATALINA_HOME/bin/commons-daemon.jar:\ $CATALINA_HOME/bin/bootstrap.jar case "$1" in start) # # Start Tomcat # $DAEMON_HOME/jsvc \ -user $TOMCAT_USER \ -home $JAVA_HOME \ -Dcatalina.home=$CATALINA_HOME \ -Djava.io.tmpdir=$TMP_DIR \ -outfile $CATALINA_HOME/logs/catalina.out \ -errfile '&1' \ $CATALINA_OPTS \ -cp $CLASSPATH \ -Xms256m \ -Xmx384m \ org.apache.catalina.startup.Bootstrap # # To get a verbose JVM #-verbose \ # To get a debug of jsvc. #-debug \ ;; stop) # # Stop Tomcat # PID=`cat /var/run/jsvc.pid` kill $PID ;; *) echo "Usage tomcat start/stop" exit 1;; esac This is for an install of Tomcat 5 to the directory of /tomcat/tc5 The java home dir is /tomcat/java If you followed the install directions your jsvc executable(DAEMON_HOME) will be in /tomcat/tc5/bin ($CATALINA_HOME/bin) if not then do a search for jsvc. If you do not have the Tomcat5 version then change the line: org.apache.catalina.startup.BootstrapService to this: org.apache.catalina.startup.Bootstrap I have added two setting for my memory: -Xms256m \ -Xmx384m \ There are other way to set this in the file but mine works for me so I left it alone. Set the values to meet your needs or delete if you plan to run the default. Now while you are still in the init.d directory #./tomcat start tomcat should start up and if you do a ps -ax you will see jsvc listed. If you do then it's all down hill from here. #cd /etc/rc3.d #ln -s ../init.d/tomcat /etc/rc3.d/S15tomcat #ln -s ../init.d/tomcat /etc/rc4.d/S15tomcat #ln -s ../init.d/tomcat /etc/rc5.d/S15tomcat Now to make life a little easier #ln -s /etc/init.d/tomcat /usr/sbin/tomcat Now from any prompt enter #tomcat stop or #tomcat start to stop/start tomcat. Just a note: The httpd starts at S15 also. If you are running both Tomcat and Apache set this to either 16 to start it after Apache or 14 to start it before Apache. I only run Tomcat so I used 15. And just to let those who don't know only files that are named SXXsomething, where XX is a two digit number that indicates the starting order of the files, are started. The file with a KXXxx are not started. And yes that is an upper case S or it will be ignored. Good luck and watch for typos.

(newbie q) Connector vs running standalone Tomcat as root
I'd like to hear people's opinions on the best way to have Tomcat accessible via standard ports (80 and 443). As I understand it, under Linux (and other unixes), ports < 1000 must be run as root. I've also read that there are some difficulties running Tomcat as root. I gather that the alternative is to run Tomcat via a connector from Apache. I have no particular need to run Apache - nearly everything on the site I'm putting together requires Tomcat. Is running Tomcat as a root process really impossible and/or problematic (under Linux)?

Re: How to limit time for Connector threads?
Hi Yoav, What the original poster meant is not that there is a race condition in Tomcat, but in his own web application. Maybe we should try to point him into the direction of fixing the problem. So there I go: - When it "hangs", if on Unix/Linux, kill -QUIT your Tomcat process, and you will get some stack traces. - Maybe they will tell you something. If they do, you're lucky. Otherwise, post them: maybe they will tell us something. At least, you will see how many threads there are, and their state (e.g. waiting for a lock). Good luck!

RE: Vedr.: RE: How to limit time for Connector threads?
Hi Thomas, the Tomcat isn't integrated to any web server. It runs alone. The problem occurs on both ports. In better words - the Tomcat is listening on the port 8080 but there is transparent redirect from 80 to 8080 in iptables.

Hi Lipi,
are you by any chance integrating Tomcat with IIS using JK2? And does the death lock
occur whether you use port 80 or 8080?

Basically when you build Apache (from source on Linux), make sure you build it with "so" support, eg ./configure --prefix=/usr/local/apache --enable-module=ssl --enable-module=so make; make install; Then get mod_jk source from jakarta.apache.org, and unpack, and build as follows (in the unpacked dir): ./buildconf.sh ./configure --with-apxs=/usr/local/apache/bin/apxs --enable-EAPI If you don't yet have a modules directory, then mkdir /usr/local/apache/modules cp apache-1.3/mod_jk.so /usr/local/apache/modules You still have to create a workers.properties file, and add the JKxx settings into your Apache httpd.conf file, to get the two to talk together. I know this instructions are vague, but hopefully in conjunction with others docs, you will be able to get Apache and Tomcat connected using JK. They do work really well together (with Apache frontending your SSL transactions, fielding static resources, compressing responses, and load balancing between two or more TC servers) - it is worth perservering.

JK connector -- isapi2 -- file upload
Hi All, I've search the archives and I've seen several posts indicating that there is a bug in the isapi connector in regards to large file uploads (or not that large, since the error seems to occur at or around 50Kb.) The problem being that "the stream ended unexpectedly. The strange thing is, I don't see this problem when I upload a large file (3M) within our intranet (I'm using IIS6, Tomcat 5 & jk2.0.4), only when I try to access from the internet. This leads me to believe there is some sort of timing problem (the connector trying to grab data that hasn't yet arrived?) Interestingly, I solved the problem by turning debug on - forcing the isapi connector to log debug messages and making is slow down a bit. That 3M file uploaded with no problem. So, here's the question ... is there a properties file, ini file ... anything ... where I can set the size of the buffer in the connector? It looks like it's grabbing about 8Kb each time. --JoAnn - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

tomcat jk1.2 connector and IIS logging
Hello, I am using Tomcat-4.1.29 and the jk1.2 connector (isapi_redirect.dll) to interface with IIS 6. Everything works wonderfully, except that IIS logs the cs-uri-stem as the redirect dll (/jakarta/isapi_redirect.dl). Is it possible to log the actual redirected URL (i.e index.jsp)? Without the actual URL the IIS logs are pretty much useless.

RE: JK2 connector built and installed but is there something wrong?
Hi, I had a similar problem. The line for the uri has to have a directory that is under $TOMCAT_HOME/webapps. [uri:/jsp-examples/*] would require the directory $TOMCAT_HOME/webapps/jsp-examples. As Drew said you can try servlets-examples instead of jsp-examples. Those directories are under the webapps folder by default.

Unable to connect Apache 2.0.48 to tomcat using JK2 Connector an d JNI.
Hi,
I am trying to connect tomcat 5.0 and Apache 2.0.48 through JK2
connector using JNI on Windows 2000. The channel.jni:jni init is failing.
I greatly appreciate any help with this.
Thanks,

Followed the steps below:
STEP 1: Installing mod_jk2
--
1. Copy the mod_jk2.dll into /modules directory.
2. Add the following line to httpd.conf
LoadModule jk2_module modules/mod_jk2.dll
#I also tried installing and configuring jkjni.dll in /modules.
That did not help either.
STEP 2: Configure /conf/server.xml

As far as I know, you can't just allocate the memory to the connector.
You can give the java process that runs tomcat the memory, though.

It seems to work with tomcat 4.1.18 but not 5.0.19. Is there any other command for the above combination I am using. I have confirmed that apache and tomcat are running all fine. thanks and regards barkha - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: JK Connector versus mod_proxy
Hi The primary benefit is, that using mod_jk, the request is not pushed to a proxy. Having a proxy in between gives serveral problems: - Authentication issues (as David mentioned) - Logging issues - Security issues All the last two come from the point, that each and every request is done by the same client [out of tomcats view], namely the apache server. Using proxy, the apache-server itself acts as HTTP Client and connects to tomcat. Using mod_jk, all request parameters are forwarded to tomcat, not using http at all. Tomcat can therefor see the clients IP and other things, that get hidden, if a proxy is in between. However, remember to diable access to tomcats AJP-port from the internet, since any attacker could also use the AJP protocol to give tomcat facked information. He could do a lot of attacks, giving a faked ip address and tomcat would log the wrong information.

AJP connector monitoring
Hi, I'd like to have our Tomcat servers monitored, in order to get an alarm if one of them stops responding. But they are not using HTTP at all. We are using the Coyote AJP connector because we have Apache in front of them, in a balanced configuration. So I'd like to load a page directly using a simple AJP client integrated into our monitoring tool. Do you know of any AJP client which is easy to drive? The only I know of is mod_jk(2), but I'm afraid that's overkill. Any ideas? I've googled for an AJP client, but I came across nothing that seemed useful. OTOH, I've been searching for something related to JMX monitoring. Again, the best I found involves access to the manager app. And I'd like to access it via AJP. So, we're back to the first problem. And it did not seem to me that the new JMeter tomcat monitor is any different. Anything better than setting up an Apache server with one VirtualHost per Tomcat server, only for monitoring?

RE: new apache to tomcat connector for linux
Mark, I use apache2, Tomcat 5 and JK2. It is far better for you to compile the JK2 connector yourself. It is a lot easier to do than you might think. Make sure you configure your apache2 for DSO and it is extremely simple to set it all up.

RE: TC V4.1.29 Coyote Connector / minProcessors maxProcessors / Confusion
Hi, I think your testing, servlets, configuration is all fine. The maxProcessors-1 observation is something I've noticed in the past, but as you say I don't think many people care because they deal with ~75 maxProcessors (the default value). The second observation: two requests to the same servlet always handled serially. Tomcat normally creates one instance of a servlet for every declaration in web.xml. The exception is SingleThreadModel (deprecated, don't use this) servlets. There's no provision in tomcat to create more instances as the load on the server increases (maybe there is such a provision and I've missed it?). Instead, the processing threads should call the servlet methods in parallel. I'm not sure why you're not seeing this behavior, perhaps someone else could comment, as I have to run to a meeting ;) Yoav Shapira Millennium Research Informatics >-Original Message- >From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] >Sent: Thursday, March 25, 2004 1:56 PM >To: [EMAIL PROTECTED] >Subject: RE: TC V4.1.29 Coyote Connector / minProcessors maxProcessors / >Confusion > >Yoav, > >Thanks for the quick reply... > >>Create a servlet that takes a long time to process, so you can easily >>observe the connections.

RE: TC V4.1.29 Coyote Connector / minProcessors maxProcessors / Confusion
Yoav,
Thanks for the quick reply...
Create a servlet that takes a long time to process, so you can easily
observe the connections. Then make sure you make two concurrent
requests to that servlet, and that the servlet's HTML output doesn't
contain images, CSS references, or any other entities which would cause
a separate HTTP connection to be initiated by the browser for that one
page. This type of page is the most common cause for perceived problems
with concurrent request processing.
I wasn't working with any images, etc. - reduced quickly to KISS level
configs & testing as a consequence of more than a couple of decades
worth of battle scars ;-)
Simple servlet, doGet implementation, simple HTML out, 30 second sleep.
Built several variants, different only in class name. Manual deployment,
no WAR file, a set of servlet classes in several different contexts.
Servlets HelloWait, HelloWait2, HelloWait3, etc. Contexts cctest1,
cctest2, etc.
Used a multi-tabbed browser (Mozilla) to test, though behavior the same
with separate browsers on multiple clients (enlisted the aid of several
of my cohorts). Also used lovely little multi-threaded Java HTTP test
client gadget to slam in requests from multiple clients concurrently.
First observation:
Behavior in general indicates number of concurrent requests serviced
equal to maxProcessors - 1 (not maxProcessers-minProcessors as I
suggested in earlier email).
Second observation:
This one really threw me. Independent of maxProcessors value, multiple
concurrent requests to the same servelet in the same context appear
to be handled serially - one at a time. Multiple concurrent requests,
each to a different servlet in the same context or a servlet in
another context appear to be handled concurrently, subject to my
first observation.
I was ready to buy the maxProcessers-1 thing as a simple implementation
oversight - not surprising since most use Tomcat for much higher volume
stuff. Second observation suggests something really strange with 4.1.29
(most of our earlier testing experimentation was with 4.1.27) or I have
made a really toady configuration error.
I have attached 2 representative servlet source samples - pretty
trivial, server.xml, default web.xml (renamed as web_default.xml) and
example context web.xml for servlets. Would have zipped but found
that not permitted for list mail. Maybe something in these I'm doing
wrong?
Tomcat running (for test execution) on an HP dual proc (Intel PIII 1.133
GHz) platform running Linux - RedHat 7.1 - little or no extraneous load
during the testing.
Any insight might have would be well appreciated.
Regards,
-Jim-

TC V4.1.29 Coyote Connector / minProcessors maxProcessors / Confusion
I'm a little confused regarding TC V4.1.29 Coyote HTTP/1.1 Connector attributes minProcessors and maxProcessors. Server config docs state minProcessors == number of connection threads to start initially and maxProcessors == the maximum number of connection threads that the server will create. This suggested to me that with minProcessors="1" and maxProcessors="2", the server would allow 2 concurrent connections. I tried the above values and found the server would handle 1 connection. Increasing to maxProcessors="3", 2 concurrent connections were available, and so on. Seems maximum_concurrent_connections=(maxProcessors - minProcessors), a slightly different relationship than I gathered from the docs. I was hoping someone could confirm this as normal, or is there maybe a bug that I should perhaps watch for correction of later. Additional minutia (to perhaps avoid adjacent questions ;-): Deploying Tomcat Standalone on a variety of Unix platforms. Likely will update to V4.1.30 shortly. Avoiding V5.0.x because a significant number of the (older) target systems are stuck on JVM 1.2.2 Using TC for moving data / messages, servlets only, no web pages, JSP, etc. Limiting concurrent connection count to relatively low numbers due to resource constraints on many of these platforms. Any feedback would be greatly appreciated. Regards, jblayer - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
