This file should be in \%SYSTEMROOT%\system32. If the user does not have write permission to there, then it will go to the user's TEMP directory. I'm not sure about win2k, but when using Win2003 explorer's 'search' feature will not search the 'Documents and Settings' folder. This is where the user's TEMP folder is by default.

Re: jk2 jni connector with iis - has anyone got this working?
Thanks for the advice.
I've tried the installer and it works fine for jk and the standard ajp13 connector.
I've got both jk and jk2 working with this already
But what I'm really after is getting tomcat to run in-process with IIS.

jk jni isapi connector problems
Hi all, I had a problem with iis shutting down tomcat nt service whenever there was a high load. As a cure for this - and maybe also to improve performance - I'm trying to get the in-process isapi filter working. I'm using jk connector with tomcat 4.1 on iis 5. ( The jk connector seems better documented than the jk2). My workers.properties looks like: workers.apache_log=D:\Program Files\Apache Group\Tomcat 4.1\logs\isapi.log workers.tomcat_home=D:\Program Files\Apache Group\Tomcat 4.1 workers.java_home=C:\j2sdk1.4.1_02 worker.list=defWorker worker.defWorker.type=jni # Set defWorker bridge type, here Tomcat 3.3 worker.defWorker.bridge=tomcat41 # Set defWorker classpath worker.defWorker.class_path=$(workers.tomcat_home)\server\lib\catalina.jar worker.defWorker.class_path=$(workers.java_home)\lib\tools.jar # Set defWorker tomcat command line worker.defWorker.cmd_line=-home worker.defWorker.cmd_line=$(workers.tomcat_home) # Set defWorker Tomcat/JVM settings worker.defWorker.jvm_lib=$(workers.java_home)\jre\bin\client worker.defWorker.stdout=$(workers.apache_log)\jk_stdout.log worker.defWorker.stderr=$(workers.apache_log)\jk_stderr.log worker.defWorker.sysprops=tomcat.home=$(workers.tomcat_home) The error message I'm getting in the isapi log file is : [Fri Feb 20 14:22:31 2004] [jk_jni_worker.c (401)]: Into validate [Fri Feb 20 14:22:31 2004] [jk_jni_worker.c (441)]: Fail- no jvm_dll_path [Fri Feb 20 14:22:31 2004] [jk_jni_worker.c (628)]: Into destroy [Fri Feb 20 14:22:31 2004] [jk_jni_worker.c (639)]: In destroy, JVM not intantiated [ What have I missed?

NT Service shutsdown unexpectedly
My setup is Win2k server, Tomcat 4.1.24 installed as a Windows Service, IIS 5, JSDK 1.4.1_02. I'm using the JK2 connector and here's the copy of my workers2.properties. # change this to your own location [shm] file=D:/Program Files/Apache Group/Tomcat 4.1/temp/shm.txt size=1048576 # Define the communication channel [channel.socket:localhost:8009] info=Ajp13 forwarding over socket tomcatId=localhost:8009 [logger.file:0] level=INFO file=D:/Program Files/Apache Group/Tomcat 4.1/logs/iis_jk2.log # uses the newly created File logger as the default one.. [workerEnv:] logger=logger.file:0 # Map the Tomcat examples webapp to the Web server uri space [uri:/axis/services/AuthService*] [uri:/policeAdmin/*] [uri:/ccWeb/*] [uri:/manager/*] I've developed a Struts based app that uses the Commons Connection Pool to read/ write data from an Oracle database. Everything works fine when I'm testing the app by myself. The only slightly puzzling thing is that I get a stream of errors logged from the ISAPI filter - typical messages are: Thu Feb 12 09:51:24 2004] (error ) [jk_worker_ajp13.c (416)] ajp13.service() ajpGetReply recoverable error 12 [Thu Feb 12 09:51:24 2004] (error ) [jk_channel_socket.c (557)] channelSocket.receive(): Error receiving message body -1 0 [Thu Feb 12 09:51:24 2004] (error ) [jk_workerEnv.c (482)] workerEnv.processCallbacks() Error reading reply So far I've ignored these - because everything seems to work. Can anyone tell me how to stop these messages? However - when I increase the load on the site in stress testing - the Tomcat service unexpectedly shutsdown. This is repeatable. I get a Dr Watson in the event viewer log - but no indications of any other error in the Tomcat logs But if I run Tomcat from the command line there is no problem - the site copes well with the extra load. I've noticed that have been other posts describing similar behaviour. Is this a reported bug? Is there a cure? Thanks in advance Tariq - BT Yahoo!

Switching off logging
I'm using log4j in my web app - and that's all working fine - but strangely I'm also getting some log messages in stdout. Do I need to set the level for the root logger? If so - could someone show me how. On a related issue - if I'm running Tomcat (on Windows) from the command line - is there a way to specify where I want stdout and stderr to go? Thanks - BT Yahoo!
