jk_nt_service
Tomcat developers, Can I suggest we bring back jk_nt_service.exe for running Tomcat as a service for 5.0.x? It works perfectly fine with TC4.1 and is a lot more flexible and easier to use for the end users. Plus I have had several crashes of the JavaService exe that is currently distributed with TC. I also wrote a Service Manager for it a couple of years ago. http://issues.apache.org/bugzilla/show_bug.cgi?id=3798. We've been using it at my company for the last couple of years and find it extremely useful. If there is nobody to maintain it, then I volunteer. Dave.

RE: jk_nt_service
I was talking about my experience with TC4.1 here. The tomcat.exe (JavaService) crashes on me every now and again. So we only use jk_nt_service.exe now. I didn't know TC5 has already got something that is implemented differently from TC4.1. Is there any documentation about procrun?

RE: PATCH: jk_nt_service can't automatically be restarted by Windows Service Control Manager upon crash
If you really want the service code to be aggressive about restarting Tomcat, I would suggest just calling start_tomcat() again. This would avoid any dependency on the Service Control Manager's reaction to ungraceful exits. In fact, I've never seen any documentation from Microsoft about such restarts. The only automatic service startups that I know about are upon booting. Can you send a reference to MS documentation about this? In addition, I don't think you would want this to just keep restarting indefinitely. If the vm is crashing a lot then there's something going on that needs to be looked at. Such restart functionality should be limited to a certain number of retries. Continuing to run the vm might interfere with other software running on the same machine. Especially if the vm is crashing due to some unusual resource consumption. Just my 2 bits worth. -David -Original Message- From: Dave Ringoen [mailto:[EMAIL PROTECTED]] Sent: Thursday, August 30, 2001 2:55 PM To: '[EMAIL PROTECTED]' Cc: Chien-Ming Huang; Brian Enright; Rob Webb; Patti Vrobel; Steven Velez Subject: PATCH: jk_nt_service can't automatically be restarted by Windows Service Control Manager upon crash We're using Tomcat at our company with considerable success, but discovered that if java.exe crashes for some reason, the Tomcat service won't restart automatically.

RE: PATCH: jk_nt_service can't automatically be restarted by Windows Service Control Manager upon crash
As of Win2000 (not sure if this existed in WinNT) you can configure a service to attempt to recover if it dies. This is fairly flexible in that you can cause it to attempt up to three restarts (after a delay period), execute a file on failure, reboot the system, etc. We might as well use the facilities the OS provides instead of duplicating this inside the service.

Such restart functionality should be limited to a certain number of retries. Continuing to run the vm might interfere with other software running on the same machine. Especially if the vm is crashing due to some unusual resource consumption. Just my 2 bits worth. -David -Original Message- From: Dave Ringoen [mailto:[EMAIL PROTECTED]] Sent: Thursday, August 30, 2001 2:55 PM To: '[EMAIL PROTECTED]' Cc: Chien-Ming Huang; Brian Enright; Rob Webb; Patti Vrobel; Steven Velez Subject: PATCH: jk_nt_service can't automatically be restarted by Windows Service Control Manager upon crash We're using Tomcat at our company with considerable success, but discovered that if java.exe crashes for some reason, the Tomcat service won't restart automatically. I diagnosed the problem and came up with this discovery and a proposed fix. jk_nt_service.exe exits too gracefully if the java.exe process dies, notifying the Service Control Manager that it is shutting down. When Service Control Manager receives the shutdown message, it does not restart the service. It assumes that the service was supposed to be shut down. This patch makes jk_nt_service exit more abruptly without notifying SCM. With this patch, SCM will correctly initiate a restart of the Tomcat service. I couldn't file this in Bugzilla because Bugzilla was down. Thanks for your consideration on this patch. I'm very impressed with the Tomcat development approach and process.

Problem using jk_nt_service (with a blank in tomcat_home directory path)
Hi, I am trying to make Tomcat as NT service. It works fine when tomcat_home directory is a continuous string. But, it does not work when I use the directory name with a blank. For example, if the tomcat_home directorypath is c:\jakartatomcathome\ but causes problem if it is c:\jakarta tomcat home\ Can somebody please suggest me a solution. Thanks, Amit Sarkar [EMAIL PROTECTED]
Re: [PATCH] jk_nt_service shutdown
Luke,
I apologize for not giving you credit for this patch -- it was included (along
with other patches) by someone else. But thanks!!!

Hi!
It would seem that the Jakarta NT Service fails to properly shutdown Tomcat.
Examining the code shows that it does the right thing and sends the ajp1[23]
shutdown message but then happily proceeds to terminate the Tomcat process
before it has a chance to shutdown gracefully. Oops!
The patch to fix it is below. This patch also includes a fix to the .dsp
file, required by the mod_jk reorganisation.
Enjoy!
