IIS Experience Anyone?
Hi, I'm still looking for anyone who has experience with the IIS plugin (ISAPI_redirect.dll). So far, nobody will admit to it. :-( (I understand.

Re: IIS Experience Anyone?
Hi! Yes, I have problems. The filter shows up correctly in IIS, and it executes fine up to the point where it needs to talk to Tomcat. Then nothing further on that page request appears in the log, and The specified module could not be found is returned as the result of the page request. My previous messages to the group were submitted wth the subject: IIS Plugin can't find Module ?? It seems like this is just about the only symptom of failure that anyone reports. Here's from my the last submission: Because I'm getting Windows Active/X error messages in response to servlet requests, it appears that my problem has to do with environmental assumptions that are not satisfied by my version of IIS 5.0 on Windows XP. I've read that the version of IIS included with XP is not the full version, so perhaps that's the problem. Who knows... But, my reason for experimenting is that I need to use Tomcat servlets on Unix servers from IIS 6.0 on a Windows 2003 system to which I do not yet have access. And now, since I've struck out trying to experiment with my desktop system, I'm curious about other people's experiences. If you've tried to use ISAPI_redirect.dll v 1.2.20 (successfully, or not), could you reply with a few words? For example, what Windows OS and IIS versions we're you using?

IIS Plugin Experience Anyone?
So far, there have been no responses to my recent requests for help with the IIS plugin (ISAPI_redirect.dll v 1.2.20).

Re: IIS Plugin can't find Module ??
Maybe I should walk before running. The plugin fails the same way with a single worker (i.e., without load balancing). My current theory is that maybe the problem is that I'm using the root context.

Re: IIS Plugin can't find Module ??
Apparently, The specified module could not be found is a Windows Message. Although the ISAPI_redirect dll is being loaded, it must be using COM/ActiveX/.NET to ask for something else that isn't available on my system once it decides to forward a page request to Tomcat.. What module would that be? Beats me. I'm using the version of IIS 5.0 that comes with XP. As before, suggestions would be appreciated. -- Scott. Scott Danforth wrote: Nope. It fails the same way for HelloWordExample in the servlets-examples context. Any ideas appreciated. Anybody ever seen The specified module could not be found when using isaspi_redirect.dll? -- Scott.

mod_jk sticky session now working !! My bad.
Aha!!! I was confused by the XML. I was changing the Engine element that was previously commented out, and this, of course, is followed by another (the real one, which wins, and didn't have a jvmRoute). Thanks so much! Your comments helped me find my problem. Thanks, -- Scott. Scott Danforth wrote: Hi Mladen, I really appreciate your help, and am happy that you're seeing a problem in the log output. I think I've got the Engine attributes specified correctly, and the two different jvmRoute values do show up in the mod_jk log. Engine name=Standalone defaultHost=localhost debug=0 jvmRoute=tomcat1 / Engine name=Standalone defaultHost=localhost debug=0 jvmRoute=tomcat2 / Maybe if I give the Engines different names? It sounds like we're expecting the jvmRoute to be appended to the sessionId that is returned in the Set-Cookie header? If so, I guess mod_jk is working as expected, and I'm just not getting the right sessionid created by Tomcat. I'm not using Boss. Just Apache and Tomcat on a single Solaris machine. -- Scott.

mod_jk sticky session not working??
I'm trying to use jk1.2.20 mod_jk with Apache 1.3 for load balancing two tomcat services and sticky sessions aren't working. My application requires authentication, and displays a login on a new session. When I kill one of the tomcats, the application works fine (i.e., the authenticated session is retained and used for each subsequent request). But if both workers are running, mod_jk ping-pongs between them (which results in new sessions being created on each request). The thing I think is most revealing is that when I run with only one worker alive (so the application works), mod_jk is still trying to round-robin the two workers. Here's are some excerpts from mod_jk.log that clearly show mod_jk trying to use both tomcat1 and tomcat2 for the same session. (is partial sessionid a clue??) What's going on, and how do I fix this? -- Scott. service sticky_session=1 id='B4FE8293E8E81F8071F39EDD1E594BEC' [Thu Feb 22 19:08:13 2007] [3786:] [debug] get_most_suitable_worker::jk_lb_worker.c (733): searching worker for partial sessionid B4FE8293E8E81F8071F39EDD1E594BEC [Thu Feb 22 19:08:13 2007] [3786:] [debug] get_most_suitable_worker::jk_lb_worker.c (785): found best worker tomcat1 (tomcat1) using method 'Request' service sticky_session=1 id='B4FE8293E8E81F8071F39EDD1E594BEC' [Thu Feb 22 19:08:16 2007] [3786:] [debug] get_most_suitable_worker::jk_lb_worker.c (733): searching worker for partial sessionid B4FE8293E8E81F8071F39EDD1E594BEC [Thu Feb 22 19:08:16 2007] [3786:] [debug] get_most_suitable_worker::jk_lb_worker.c (785): found best worker tomcat2 (tomcat2) using method 'Request' service sticky_session=1 id='B4FE8293E8E81F8071F39EDD1E594BEC' [Thu Feb 22 19:08:16 2007] [3786:] [debug] get_most_suitable_worker::jk_lb_worker.c (733): searching worker for partial sessionid B4FE8293E8E81F8071F39EDD1E594BEC [Thu Feb 22 19:08:16 2007] [3786:] [debug] get_most_suitable_worker::jk_lb_worker.c (785): found best worker tomcat1 (tomcat1) using method 'Request' service sticky_session=1 id='B4FE8293E8E81F8071F39EDD1E594BEC' [Thu Feb 22 19:10:47 2007] [3788:] [debug] get_most_suitable_worker::jk_lb_worker.c (733): searching worker for partial sessionid B4FE8293E8E81F8071F39EDD1E594BEC [Thu Feb 22 19:10:47 2007] [3788:] [debug] get_most_suitable_worker::jk_lb_worker.c (785): found best worker tomcat2 (tomcat2) using method 'Request' [Thu Feb 22 19:10:47 2007] [3788:] [debug] service::jk_lb_worker.c (860): service worker=tomcat2 route=tomcat2 service sticky_session=1 id='B4FE8293E8E81F8071F39EDD1E594BEC' [Thu Feb 22 19:10:47 2007] [3788:] [debug] get_most_suitable_worker::jk_lb_worker.c (733): searching worker for partial sessionid B4FE8293E8E81F8071F39EDD1E594BEC [Thu Feb 22 19:10:47 2007] [3788:] [debug] get_most_suitable_worker::jk_lb_worker.c (785): found best worker tomcat1 (tomcat1) using method 'Request' [Thu Feb 22 19:10:47 2007] [3788:] [debug] service::jk_lb_worker.c (860): service worker=tomcat1 route=tomcat1 service sticky_session=1 id='B4FE8293E8E81F8071F39EDD1E594BEC' [Thu Feb 22 19:11:57 2007] [3790:] [debug] get_most_suitable_worker::jk_lb_worker.c (733): searching worker for partial sessionid B4FE8293E8E81F8071F39EDD1E594BEC [Thu Feb 22 19:11:57 2007] [3790:] [debug] get_most_suitable_worker::jk_lb_worker.c (785): found best worker tomcat2 (tomcat2) using method 'Request' [Thu Feb 22 19:11:57 2007] [3790:] [debug] service::jk_lb_worker.c (860): service worker=tomcat2 route=tomcat2 - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
soft shutdown
We want to convert an application currently based on JServ to Tomcat. Does Tomcat allow you to rotate servers using a soft shutdown that routes new sessions to a different container while continuing to support existing sessions?

2nd Try for Advice on Tomcat Shutdown
Hmmm. I just joined this mailing list today, and I'm happy to see that there's lots of action. But, so far, nobody has responded to my posting. Maybe I'm asking about something so trivial that everybody thinks somebody else will respond... Anyway, having said that, I'll try again. Hopefully, somebody will respond with a comment. I want to convert an application that currently uses JServ (with load balancing) to Tomcat. In reading about Tomcat everything looks good, but there's one aspect of our current approach that I don't see any support for: putting a worker into shutdown mode without completely stopping it, and then waiting for all of its current sessions to be concluded. Load balancing on JServ was based on a memory-mapped file that stored the current state of different JServ instances, and you could write to this file to change that state. One of the useful states was called shutdown. In this state, mod_jserv would continue to route page requests for existing sessions to their corresponding Jserv instance, but no new requests would be routed there. So you could put a Jserv worker into shutdown mode, and then wait for it to become quiescent, after which you could kill the worker and perform maintenance on that system. This was sometimes called a soft shutdown. We run a 24/7 application and use this approach to rotate through servers while releasing new code. I found archived mail (from 2002) with a query along these lines that suggested a way of accomplishing this for Tomcat, but don't know what the ultimate outcome of that suggestion was (if anything). http://mail-archives.apache.org/mod_mbox/tomcat-dev/200205.mbox/[EMAIL PROTECTED] I kind of expect there must be something in Tomcat like JServ's soft shutdown for people that want to run 24/7 while bringing workers up and down. Can somebody tell me what the Tomcat solution is?

Re: 2nd Try for Advice on Tomcat Shutdown
Thanks, Hassan, I've seen session replication mentioned and suspected that might be the answer now. Just stopping a worker and letting its sessions go elsewhere is certainly more elegant than waiting around for sessions to be concluded. The only problem is that my session data isn't serializable. So it isn't going anywhere in the near term. But, again thanks. I appreciate your help. :-) -- Scott. Hassan Schroeder wrote: On 2/13/07, Scott Danforth [EMAIL PROTECTED] wrote: Hmmm.
