Hi All its me again, Every thing works fine but you have to manually map every URL servlet - I'm sure this is not correct. I'm posting this last e-mail on this subject unless someone can address the jk2_init() issue. Rest assured for all concerned I'm not even dreaming of looking at jkini in-process implementation.

The first is using workers2.properties. If you've compiled with -pcre, then perl regular expressions should work as well as individual names. Also, remember that servlets traditionally live in /app-name/servlet/servlet-name. This is controlled by the web.xml for the particular application (context) and is found in: $TOMCAT_HOME/webapps/app-name/WEB-INF/web.xml The example context is especially confusing, primarily due to the name. In Tomcat 4.1.29, you have the following: /examples/jsp/index.html /examples/servlets/index.html However, the actual location of the servlets according to web.xml would be: /examples/servlet/servlet-name So, in your workers2.properties file you will need to have the following in order to map all servlets in the examples: [uri:/examples/servlet/*] worker=ajp13:unixsocket or whatever you called your worker name. While workers2.properties works well for a small number of sites, it does not scale very well since the match lookup is linear. Another way to manage mod_jk2 mapping is detailed in the source of mod_jk2. I know, I know, reading the source is not supposed to be a requirement, but then again this is open source so you do have the opportunity. Anyway, in jk/native2/server/apache2/mod_jk2.c, there is a little documentation concerning JkUriSet. Basically, you use Apache constructs to map the location and within that you use the JkUriSet directive to map the location to the appropriate worker. I've tried both ways, and they both work well. According to the source, using JkUriSet is the preferred method. As for in-process, there has been some discussion on this mailing list about why in-process does not work with the current MPM (multi-processor modules) available for Apache httpd. The real problem seems to be that there is currently no MPM that runs all of apache within one process in UNIX, using threads exclusively to handle separate requests. Actually, this is not quite true since there is an experimental MPM that accomplishes this. However, according to the documentation this is slower than the current worker model (multi-process, multi-thread) and not recommended for production work. The problem is that when multiple processes get started, each process attempts to start its own Tomcat (if in-process is being used). This can't be done using the same server,xml. In recent kernels (Redhat 2.4.2x, generic 2.6.0, 2.6.1) there has been a new implementation of threads. It might be possible to build a new MPM that takes advantage of this. As far as I know, this is not being done (yet). This sounds like a great opportunity to make a contribution :-). Hope this has been helpful. /mde/ just my two cents . . . __ Do you Yahoo!? Yahoo!

this. This isn't exact: it is checked periodically. -1 means sessions won't be swapped out for this reason, although they may be swapped out for maxActiveSessions. If set to = 0, guarantees that all sessions found in the Store will be loaded on startup. maxIdleBackup: Sessions will be backed up (saved to the Store, but left in active memory) if idle for this long (in seconds), and all sessions found in the Store will be loaded on startup. If set to -1 sessions will not be backed up, 0 means they should be backed up shortly after being used.

The only way I found to avoid them was a rather long one. In order for Apache + mod_jk2 to find neighbour children is to configure shared memory for mod_jk2. And it must be configured on both Apache and Tomcat side. If you drop Tomcat side, then it will complain. :-) For shared memory in Coyote-jk2 handler, you need to build jkjni.so (you may screem in agony :-)). JK-JNI gives you Java Native Interface functionality, which includes UNIX SHM and UNIX file sockets. In order for jkjni.so to function correctly, it must have an environment variable serverRoot defined on the process level, or it will not be able to locate workers2.properties (it is in Apache's config dir). To be honest, jkjni.so was designed for another purpose - running Tomcat from within Apache process (in-process). This environment variable is provided by Apache. All of us who wish to run a standalone Tomcat and still use jkjni.so must emulate this. The only way I found to do that was to place export serverRoot=/etc/httpd/2.0 in Tomcat's config/startup scripts. Like I said - it is long one.

Fw: jk2_init() Can't find child xxxx in none of the 1024 scoreboard slots
Hi Peter,
I'm using Apache 2.0.48, Tomcat 4.1.29, Jakarta-Tomcat-Connectors 4.1.29.
I'm hoping the problem it is not the mod_jk2.so module as I went to great
trouble in order to generate it on my RH9 Linux Kernal Version 2.4.20-8
platform. I had to recompile apr, apr-util code and only ant native
managed to build mod_jk2.so
Below are the following files:
error.log from Apache 2.0.48
jk2.properties
workers.properties
snippet from httpd.conf
snippet from server.xml
Many thanks for any help you may be able to give.
Cheers,
George

The quickest way to do this is,
( assumes testing with http://localhost )
1) copy the /WEB-INF/classes directory from the /examples/WEB-INF/classes
to your directory.
2) Add the html code to call one of the servlets.
If you can call one of the example servlets then you can backtrack and get
ride of the example servlets and JSP and add your own.
If testing on localhost make sure you have workers.properies,
property.host
=localhost
AND
make sure the servlet.xml Context = localhost
When that's complete you'll want to clean up the web.xml file also.

Yep, without going into too much detail IT DOESN'T WORK ITS REALLY BROKE.

The build is stuffed and its not the version of libtool or anything else something is broke when you try to build on RH9 exactly what is up to the many lib, builds scripts between Ant and Make - if I have enough time over the next decade I may be able to solve it however apache 1.3.29 can talk to Tomcat 4.1.29 for now through webapp connector, Now if through some miracle someone out there has managed to REALLY build this on current vanilla install of RH9 (not enterprise) I want a copy of mod_jk2.so file, httpd.conf, serer.xml, copy of the SOURCE jakarta-tomcat -connector used, a README file with exactly what you did and the best part for last I want a dump of your system output from the build of the mod_jk2.so in order to make me a believer. Keep in mind I want to build from source no binaries and Apache 2.0.48 connecting to Tomcat 4.1.29 through mod_jk2.so - all built from source just in case you mist my point. Greatest apologies but like many out there I'm very frustrate when stuff that I really don't want to know much about stops working because of compromises in testing on the various platforms or the Readme files aren't updated along side the respective release even though this is after all open source.

jk connector Apache 1.3.29 Tomcat 4.1.29 too slow
Things that I'm using Platform: Linux 9 Apache 1.3.29 - built from source Tomcat 4.1.29 - built from source jakarta-tomcat-connectors-4.1.29 - yep also built from source - built my own mod_jk.so Everything works but its very very very strange - its too slow to load the jsps/servlets on every second request. If I make a request in the browser, every second request I need to hit STOP in the browser and make the request again - that way things get loaded in the usual time. Its particularly slow on loading images irrespective if its a second request or not. When I look into the mod_jk.log file apache is doing its job of passing the requested to tomcat to process however tomcat is not responding (as if some termination of a previous requested is still resolving!). hope someone can help as I've spent the last 3 weeks on this :-( many thanks in advance for any help, George Not everything that counts can be counted, and not everything that can be counted counts.

The browser just makes a HTTP get request to the web-server (in this case tomcat) requesting the URL of the image to be included in the web page. i.e. in a standard jsp/servlet response to a web request the image request is embedded in a img src=.../somedir/some-img.gif. This is going to cause a browser request directory to the directory containing the image, which can also be duplicated in the browser. The only potential method that can catch most (but not all) of these would be to create a separate image handling jsp/servlet, say imageHandler. When imageHanlder servlet recieves an image request it can check the http-referrer header and ensure that the referrer is the url of the page to which the images are supposed to load, i.e. is the page containing the images in /servlet/somepage then the http-referrer that imageHandler see should be able to checked that it is /servlet/somepage. Someone can circumvent this control by the Internet, but just manually setting this header themselves (via a program or the like) and then having access directly to the images You would then have to update all image referrences on the somepage servelt/jsp however to something like img src=/servlet/imagehandler?gif=somerefernce.

Re: NIGHTMARE
Hi Arni, About three years ago we went through many web servers in the market and found Tomcat simple to install. We found it simple because we had a lot of exposure to different web servers that run in a number if different environments and an extensive background in the various programming and scripting languages targeting the web development especially in the area of java. What we did find was a lack of documentation beyond the out of the box install type.The way we resolved this was to use this great e-mail list and constructed our own internal knowledge base in addressing the various issues we encounter on a day to day basis.(we now do this as a standard procedure with all our open source projects, I'm sure there is a similar archive maintained by the apache/tomcat group ) Till this day I think I've only ever had to post two e-mails, this is my third - thanks for the opportunity :-) Regards, George Shafik Great works are performed, not by strength, but by perseverance; yonder palace was raised by single stones, yet you see its height and spaciousness.

Server. This is the only way we found in order to integrate IIS4/5 into our
Web Site alongside tomcat. My main concern is how are you resolving the URL
calls to the appropriate server. Its clear you will have duplicate document
structures on each of the JVMs but is this where things get resolved ?

Subject: RE: Redirection and Load Balancing
We're running Linux, Tomcat 3.n (currently 3.2.2), and Apache 1.3.19 (and
also 1.3.12).
We did rebuild binaries, but didn't really need to. The only weird thing
we
did was so the hardware load balancer in front of our servers kept cookie
and/or jsessionid sessions on the same physical hardware so mod_jk
loadbalancing could do its thing.
Tomcat:
server*.xml: one for each tomcat JVM, then in your startup script do
something like:
java -Dtomcat.home=${TOMCAT_HOME} org.apache.tomcat.startup.Tomcat -f
${TOMCAT_HOME}/conf/server1.xml $@
so you can run everythint out of the same tomcat home.
workers.properties:
worker.list=lbworker, worker1, worker2,...
# duplicate these lines for every worker... (not lbworker)
worker.worker1.port=number # matching the port number from this
instances server*.xml file
worker.worker1.host=localhost # never tried a remote machine, but you
could
worker.worker1.type=ajp13 # or ajp12 if you're using it
worker.worker1.lbfactor=2 # we don't use this
worker.w1a.cachesize=1 # or this
worker.lbworker.type=lb
worker.lbworker.balanced_workers=worker1, worker2,...
ModJk.conf: use the auto-generated file as a template and mount the
contexts
you want to balance on the lb worker...
JkMount /servlet/* lbworker
Apache: append the ModJk.conf file to httpd.conf

Sounds great Paul.
What sort of environment are you using mod_jk in ?
- OS platform
- Version of Apache, Tomcat
- How many versions of Apache and Tomcat are you running in parallel in
order to mirror your Web Site so you can perform your load balancing.
- Are all your binaries custom built ?
Can you please e-mail me directly all relevant Apache/Tomcat configuration
files that I need to alter in order to use mod_jk in the manner you
describe. If this is too difficult cut and past the relevant pieces
commenting on where they are from into one file.

Subject: RE: Redirection and Load Balancing
You can use mod_jk to load balance between different JVMs running
Tomcat.
Works well, we use it.
The JVMs could then also be on remote machines to either each other,
and/or
the machine running Apache.
mod_jk will preserve sessions for you so that subsequent request go to
the
right JVM.
You'll need to configure the workers.properties, etc. to use the
'loadbalancer' worker.

Subject: Redirection and Load Balancing
Hi All,
Current System Architecture
Apache : 3.17 (Custom Build)
Tomcat : 3.2.2 (Custom Build)
Deployment : war files.
Platform : Red Hat Linux 6.2
We are after a method to redirect based on a limit on the number of page
hits or the load on the current Web Server.
The redirection needs to be performed by Apache or Tomcat not by the web
page itself. Currently we are redirecting the user to another Web Server
from the current page as the page hits reach a certain limit or the load
is
too much on the current box. A better way to conduct this is to redirect
the
call to another Web Server at the Web Server or Servlet Engine level, in
our
case that's Apache or Tomcat. Its not clear to us where in Apache or
Tomcat
we can configure things based on page hits or load if its possible to do

Concurrent VMs accessing the one Connection Pool
Hi All, Has anyone implemented a connection pool using more than one VM machine (Tomcat) or put it another way, has anyone been able to get concurrent servlet engines (Tomcat) accessing the one common connection pool ? Any examples using Apache with multiple versions of Tomcat running "in-process" on dedicated linux serverswithan Oracle backend will be greatly appreciated. Cheers, George

Re: SSL Help
Hi All, After server months of development we are ready to implement security part of the system and are very confused on how to go about it and hopefully someone in this mailing list has tackled this issue successfully. ... Our systems are: Linux Red Hat 6.2 Apache 1.12.? - Compiled/Built in our environment Tomcat 3.2.1 - Compiled/Built in our environment JDK 1.2.2 Oracle 8.1.6 As far as we understand you can apply SSL at: 1) OS level with a product like OpenSSL 2) Application Level with Sun's JSSE 1.0.2 Our main concern is performance, then portability of code between different systems. Performance Do you get better system performance by applying SSL at the OS or at an application layer ? I would think at the OS level as the Security Software will be written in a language like C making it very fast as it will be native to the process used the target machine. Code IF you decided to use JSSE 1.0.2 implementation of SSL what impact will it have when you port your code to a system that implements SSL at the OS level ? If SSL Code is introduced correctly into the Framework then the impact will be minimal between system implementations as it only should involve rippling out a base class. As mentioned performance is a very important issue and having several layers of security from the firewall against the web server to the firewall against the database to security sitting at the socket level encrypting and decrypting everything that comes in its path not to mention getting Java to do its magic through the interpreted bytecode! At this stage in our development cycle we have a very superficial understanding of the impact and possible solutions when it comes to successfully implementing security and welcome any advise in this area.
