This saddens me. I was under th impression that JK2 was more advanced. What are the reasons for abandoning it? The concept of workers, channels and such stuff was great, although it took some time to grasp. Some features of mod_jk2 will be ported to mod_jk. Is there any comprehensive documentation on this? Also, if we are to drop JK2, will there be an effort made to make comprehensive documentation on JK1? The other development is mod_proxy_ajp as part of the apache webserver project. That's for the Apache 2.2. Nice to know, but in the distant future for me.

Sorry, but I think you are wrong. There have been several post in the last days from the developers, that clearly say, that there will be no further development for mod_jk2.

That's a bit too general. Tomcat can do all the things (PHP, CGI, SSL), the real question is: can tomcat do it good and fast enough for a certain use case. That can only be decided from case to case.

Just a guess: - Use Apache + mod_jk(2) + 2 tomcat instances - Use sticky sessions (look at the jvmRoute of the engine tag) - Use the load factor to distribute 100% of the requests to the first instance. - Update the second instance. - Change the load factor to distribute 100% of the requests to the second instance. - Wait after all session moved to the second instance update the first instance and reverse the I haven't tried any of this but as far as I can remember I have seen posts in this list that indicate that this should be possible. -Original Message- From: Christian Mittendorf [mailto:[EMAIL PROTECTED] Sent: Friday, October 01, 2004 12:15 PM To: [EMAIL PROTECTED] Subject: Howto deploy a new version of my webapp without disturbing the customer?

The existing sessions in the old application can continue their order process. When the number of open sessions in this old instance reaches zero, the instance is shut down.

RE: Synchronization in cluster
Why not ? As I understood the static variable holds the information for the current upload. If the session is sticky the user will stay in the same jvm and see the same static variable with each refresh. I just see some downsides: - if you want to assure that the downloads are serialised you have to implement a locking mechanism. - you loose the central point to see all states at the same time. - if the instance that performs the update dies, the user will get to an instance that doesn't know anything about the download. -Original Message- From: Filip Hanik (lists) [mailto:[EMAIL PROTECTED] Sent: Friday, October 01, 2004 1:51 PM To: Tomcat Users List Subject: RE: Synchronization in cluster That doesn't solve the problem -Original Message- From: Ralph Einfeldt [mailto:[EMAIL PROTECTED] Sent: Friday, October 01, 2004 4:26 AM To: Tomcat Users List Subject: RE: Synchronization in cluster With this usage scenario i would recommend sticky sessions. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: Question about multiple instances instead virtual hosts
To bind a IP to an engine have a look at either:
http://jakarta.apache.org/tomcat/tomcat-5.0-doc/config/host.html
http://jakarta.apache.org/tomcat/tomcat-4.1-doc/config/host.html
For the installation structure:
First:
Have a look at RUNNING.txt in the tomcat distribution
...
Second:
We have a structure like this:
/usr/local/java/jdk/ibm1.3
/usr/local/java/jdk/sun1.3
/usr/local/java/jdk/sun1.3.1
/usr/local/java/jdk/sun1.4
/usr/local/java/tomcat-4...
/usr/local/java/tomcat-5...
/www/online/site
/log
dirctory for the log file
/conf
web.xml
server.xml
and other files that contain the site specific setup for tomcat
(tailored versions of the files that are provided by
tomcat)
make shure that the combination of IP and port are unique for
each instance of tomcat.
...
/work
Directory where tomcat stores the generated files and classes
/webapps
Directories for the contexts
/bin
start.sh
Script that calls the tomcat version that we want to use for
this site with the environment for this site:
JAVA_HOME=/usr/local/java/jdk/sun1.3.1
CATALINA_HOME=/usr/local/java/tomcat-
CATALINA_BASE=/www/online/site
export JAVA_HOME CATALINA_HOME CATALINA_BASE
${CATALINA_HOME}/bin/startup.sh
This way we can have different versions of tomcat at the same time,
all sites that use the same tomcat version use the same 'executable'
but different processes and individual configuration. If we want to
use an other version of tomcat we just have to change CATALINA_HOME
in start.sh (unless the config files are incompatible between these
versions)

RE: Problem invoking webservice from within servlets service method.
- The servlet in tomcat is talking to the same tomcat instance. [-?- The servlet running in tomcat will get it's data from a physically different server -?-] Unless the error message is heavily missleading the servlet/axis is talking to a webserver. If it isn't the iis on server B it must be a different one. One possible candidate is the local tomcat. To verify/falsify that, check the access log of tomcat for a 404 error. But 404 just makes no sense, for these reasons: Again if the message no garbage, there is a webserver that generates it. If it is generated by iis you have to find out what causes this error. Possible actions: - check the tomcat access log on server B for a 404 error - check the iis access log on server B for a 404 error - patch axis to provide more information about the environment in the stacktrace. (e.g. the response headers) - or debug the servlet - or watch the network traffic with a sniffer to verify if there really was a 404 response. -Original Message- From: KRUEGER MICHAEL [mailto:[EMAIL PROTECTED] Sent: Wednesday, April 21, 2004 2:37 PM To: Tomcat Users List Subject: AW: Problem invoking webservice from within servlets service method. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: Threads in Tomcat 5
Tomcat uses a ThreadPool so Threads are recycled. If you store something in a ThreadLocal it it your resposibility to clear the stored values at the end of the use. So if you store request variables you have to clear them at the end of the request (or before storing them at the beginning of the request). Sadly the the ThreadLocal API has no means to clear the state for a thread easily. To clear it, you have to know what is stored in ThreadLocals.

And what happens with the released threads? Our login application is having problems when retrieving data from the requests. I was debugging the process by printing out the current thread name and the request parameter values. Everything works fine when there is a different thread assigned to each request: request 1 current thread: http8080-Processor25 request 2 current thread: http8080-Processor23 request 3 current thread: http8080-Processor22 When an old thread is used for the new request, things don't work (usually the wrong parameter values are returned) and the debug output looks like this: request 1 current thread: http8080-Processor25 request 2 current thread: http8080-Processor23 request 3 current thread: http8080-Processor25 Our application uses ThreadLocal to create a Hashtable with the current request parameters as a cache storage. Very often the same thread is used for more than one requests, the parameter values are retrieved from the cache instead of using the new values.

RE: Possible thread crossing
You have basically this options: - The error was introduced by the update of the underlying software - The error was there before and somehow just didn't show That is shows up after the update may be coincidence. Or it just show because the new system is faster/slower than before. From your description the second one is (in my opinion) most likely. -Original Message- From: Denise Mangano [mailto:[EMAIL PROTECTED] Sent: Thursday, March 25, 2004 5:46 PM To: Tomcat Users List Subject: RE: Possible thread crossing It would appear so, but the strange thing is that I have been using the same program since July of last year.

RE: Possible thread crossing
Probably you tried to access the variables from a static method.
(Which isn't static any longer or has been removed or changed in
way that it doesn't access the variabled)
That the problem shows up only recently may be caused be a change
in the usage pattern of the site or because your updated environment
has different timings than before.
I also have seen errors that where just not noticed for several
months, than you make a change to the system, look closer at the
system, see the error and think 'Oh how can this change cause
such an error.

For the life of me I cannot recall why I made them static!!!
There are
a few other variables that I had static as well. I want to say that
when I was writing the program I was getting compile errors
stating that
I cannot reference non-static variables and changing them to static
allowed the program to compile (major newbie mistake/assumption I am
sure).
I just created a copy of my program and removed static from the
serialNumber as well as a few other variables I had made static and
everything compiled fine. Very strange though that it has
been working
fine this entire time??? :-/ I guess the next step is to make this
change in the live program and monitor it very closely...
Thanks again.

SiteMesh is VERY good! See http://www.opensymphony.com/sitemesh/ It looks complicated, but it's not, and you can control through an XML file which files get filtered or not (by pattern matching URLs). The real power is that you build your jsp pages and focus on the core presentation task in hand, then let the sitemesh filter decorate it by extracting your page head, body etc and inserting those elements into a template page (for example). You could have a simple template that just adds extra meta tags, or specifies the style sheet or whatever you want. I've seen no downsides to using it, and speed is good too. Couple it with OSCache (http://www.opensymphony.com/oscache/), and you have a couple of blinding tools. Hope that helps. John Sidney-Woollett Hertenstein Alain said: As for Servlet 2.3 specifications, you could easily create a Servlet Filter which would intercept all your requests based on your url-pattern (defined in web.xml), and which would do something like : RequestDispatcher reqDispatcher = request.getRequestDispatcher(header.jsp); reqDispatcher.include(request, response); And then let the filter forward to the requested page (chain.doFilter()). Thus all your pages would include your header.jsp file (beware not to include header.jsp into header.jsp file, or you'll get an infinite loop ;-) ) This is quite easy to implement and the best way IMHO. Have a look at the http://java.sun.com web site for more info on Servlet Filters, they are very handy as soon as you understand how they work.

RE: Possible thread crossing
That the problem is just happening for users that have the highest volume, might indicate that you have a threading problem. (Like a variable that should only be visible in the current request, is visible to concurrent requests) If there is a threading problem it's most likely in your application or a third party software. (I wouldn't bet that tomcat isn't having such issues, but it is much less likely) Can you show how you set the id in the jsp ? Can you show a example how you process the jsp ? If you can't make it public, you may post it to me directly (No guarantee how much time I will have to look at it). The memory that is used by your java is very unlikely to cause such symptoms. (In certain instances it may indirectly affect the problem by increasing the runtime for each request and this way rising the probability that requests are processed concurrently) -Original Message- From: Denise Mangano [mailto:[EMAIL PROTECTED] Sent: Wednesday, March 24, 2004 6:02 AM To: Tomcat Users List Subject: RE: Possible thread crossing I just wanted to point out again that this data appears to be getting crossed only with the clients that have the highest volume This is why I am thinking it's a java/Tomcat issue.

This webapp has been live since last year and I have never had this problem. I recently reformatted my server changing versions of Tomcat, Apache and RH. The programs and web pages I am using are the same - pulled from backups so nothing has changed. This is my java program structure: /com/beans/transaction/*.java. The pages accessing these programs are located in: /webapps/ROOT/clients/client1 /webapps/ROOT/clients/client2 etc... When someone goes to client one and accesses the java program an individual instance of the program is created, correct? So if user 1 starts a transaction from /client1 and user 2 starts a transaction from /client2 each user has it's own instance of the java program running - so technically data from one instance should not be finding it's way to another. I made some changes to my webapp but this still appears to be happening. Nix: 1. Network sniffer? If I add some debugging code to my java program is this what you mean? Or is there a tool I can actually use? 2. The two key variables are a transaction number and this serial number. Both are hard coded into the JSP pages and are not changed by anything in either my JSP or my java program. Only variables that change are personal info (i.e. address). Thanks.

RE: Horrible memory leak in tomcat 5.0.19 (JMX bug?)
To your question: I don't know. Having a delay in the jsp (or servlet) isn't enough to enshure concurrent requests. You have to do something on the calling site to enforce this. If you just call lynx as in your example, lynx will wait until the response is there. So if you delay the jsp, you just delay the return of lynx. So you have either to run more than one instace of your script at the same time or to extend the scrip in a way that it runs several lynx instances at the same time. -Original Message- From: Joseph Shraibman [mailto:[EMAIL PROTECTED] Sent: Friday, March 19, 2004 7:21 PM To: Tomcat Users List Subject: Re: Horrible memory leak in tomcat 5.0.19 (JMX bug?)

RE: Horrible memory leak in tomcat 5.0.19 (JMX bug?)
That may be a bit to simple, as this is just performing one request after the other. You may have to force concurrent request: i=1 while [ $i -lt 2 ] ; do j=1 while [ $j -lt 10 ] ; do # start lynx in background lynx -source $URL /dev/null j=`expr $j + 1` done wait # until all background tasks returned i=`expr $i + 1` done You may also have a look at ab or jMeter. They allow for a better test than home grown test like yours. (My enhancement might not help much, as the result of the script depends to a degree on the time that lynx needs to start.) -Original Message- From: Joseph Shraibman [mailto:[EMAIL PROTECTED] Sent: Thursday, March 18, 2004 8:32 PM To: Tomcat Users List Subject: Re: Horrible memory leak in tomcat 5.0.19 (JMX bug?)

RE: url-pattern pb in security constraints
According to the spec (Chapter 11.2): spec A string beginning with a / character and ending with a /* postfix is used for path mapping. A string beginning with a *. prefix is used as an extension mapping. A string containing only the / character indicates the default servlet of the application. In this case the servlet path is the request URI minus the context path and the path info is null. All other strings are used for exact matches only. /spec So /pages/*.jsp is not a valid pattern mapping.
