AW: jk connector and response.sendRedirect()
I'm not a programmer but an administrator. We have had an similar problem and solved it by changing the apache option UseCanonicalNames from on to off. [when UseCanonicalName ist on, everytimes you call response.sendRedirect() the apache takes the servername (from httd.conf) and make the absolute URL. If you are switching UseCanonicalNames to off, apache takes the hostname from the incoming HTTP-Header] Maybe this tip helps Regards :o) Ilona -Ursprüngliche Nachricht- Von: Chris Egolf [mailto:[EMAIL PROTECTED] Gesendet: Mittwoch, 30. Juli 2003 16:18 An: [EMAIL PROTECTED] Betreff: jk connector and response.sendRedirect() I'm pulling my hair out on this one, but I think I've narrowed it down so I can at least ask the question... We're running Tomcat 4.1.24/Apache 1.3.27/Sun JDK 1.4.2 using mod_jk. The issue we're dealing with now, is that in some cases an existing webapp uses the response.sendRedirect() method to redirect the client to another relative URL. Previously, we were using the warp connector and everything worked fine. Now, using mod_jk, the redirect fails causing the browser to say it can't find the host. Here's what I've tried so far. I removed Apache from the mix and setup the Coyote HTTP/1.1 connector to listen to port 80. Everything works fine with this setup, so it must be a connector thing, right? With just the JK connector enabled and listening on 8009, I've added Apache back and setup Alias elements in the Host element of my server.xml. The host the browser says it can't find is the actual hostname of the machine, not the DNS entry. I believe this is a problem unique to the jk connector (or how I have it configured) and the response.sendRedirect() method. Here's the documentation from the servlet API: public void sendRedirect(java.lang.String location) throws java.io.IOException Sends a temporary redirect response to the client using the specified redirect location URL. This method can accept relative URLs; the servlet container will convert the relative URL to an absolute URL before sending the response to the client. If the response has already been committed, this method throws an IllegalStateException. After using this method, the response should be considered to be committed and should not be written to. Here's the connector and Host element stuff from my server.xml: ... Connector className=org.apache.ajp.tomcat4.Ajp13Connector port=8009 minProcessors=5 maxProcessors=75 enableLookups=true acceptCount=10 debug=0 connectionTimeout=0 useURIValidationHack=false/ ... Host name=localhost debug=0 appBase=webapps unpackWARs=true autoDeploy=true Aliasdemo.mycompany.com/Alias Aliasgoatweed/Alias Aliasdemo/Alias Aliasgoatweed.mycompany.com/Alias Aliasdemo.anotherdomain.net/Alias Aliasgoatweed.anotherdomain.net/Alias ... /Host Anyone have any ideas or see a glaring mistake on my part? I'll gladly provide more info if needed.

AW: Does Tomcat load config. files dynamically?
Hallo Yoav Web.xml for a given webapp is read when the webapp is loaded (normally on server startup), and you can have it reloaded by reloading the webapp (via the manager webapp), without restarting the whole server. If i'm reloading the webapp via manager application, all users lost there sessions, isn't it?

AW: JK2 connector
Hi John! If Apache and Tomcat are on the same machine, is there any difference concerning performance between: worker.myhost.host=localhost worker.myhost.host=127.0.0.1 worker.myhost.host=10.0.0.71 Regards :o) Ilona -Ursprüngliche Nachricht- Von: John Turner [mailto:[EMAIL PROTECTED] Gesendet: Dienstag, 22.

I have one question more : what do I have to do if http server and application server are not on the same computer ? Vincent If you are using mod_jk_2.0.46.dll, that would be mod_jk, not mod_jk2. Check out my HOWTO for Windows, it covers everything step by step. The version numbers are a little out of date, but it shouldn't matter. http://www.johnturner.com/howto Incidentally, I had a little trouble with the DLL for .46, I ended up using the DLL for .43. That was several weeks ago, it is possible the problems are fixed now, but if you run into some issues that you can't solve, you might want to try dropping back to the .43 DLL.

AW: JK2 connector
Oh, good idea :o) We are using w2k and i just now checked the maximum packetsize my machine was able to transfer without fragmentation (ping -f -l [packetsize]). It seems to be 1472 regardless of destination (localhost or ip of the host). But of course you are right, its unnecessary to busy the whole network drivers layers. Okay... i'm now going to check out all our machines if there is anywhere an IP instead of localhost (we have some troublemaker... may this resolves their problems) Thank you for explanation :o) Ilona -Ursprüngliche Nachricht- Von: Halstead, Chris [mailto:[EMAIL PROTECTED] Gesendet: Dienstag, 22. Juli 2003 18:57 An: Tomcat Users List Betreff: RE: JK2 connector Communication over 127.0.0.1 (or localhost, which should resolve to 127.0.0.1) should be more efficient than using the real IP. The MTU over loopback (127.0.0.1) is on the order of 8k in Solaris and 16k in current Linux distros, whereas the MTU over a real IP maxes at 1500. The larger MTU will prevent fragmentation of your responses into multiple packets. Using loopback should also avoid going up and then back down the network driver layers. If all your communication is local, use localhost. cheers, -chris I highly doubt it. Maybe something on the order of a few milliseconds, but certainly nothing I would worry about. Its been awhile since I looked at the mod_jk source, but my guess is it only reads workers.properties once, at startup, and if that's the case, there would be no difference in performance whatsoever.

2 newbie questions: Apache-tomcat
1. is it possibly apply aliases to tomcat? For example: the webapp-root is /www/mywebapp. I want to mount an directory /other/directory/help to the name help (httpd.conf: alias /help other/directory/help). But when i'm calling http://mywebsite/help it crash's with a 404 error:o( . When i'm using JRUN, all is okay. Jrun handle aliases without problems. But Tomcat don't??? 2. is the Option JkMount /*.jsp worker1 the same as JkMount /*/*.jsp worker1? Or means /*.jsp only the *.jsp in the root of my webapp? Can i wrote something like that: JkMount /servlet/* worker1 JkMount /anotherdirectory/servlet/* worker2 and it works? How about regexpressions in the JkMount-option? thanks very match Ilona - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
