Repost::Connection Timeout
Hello, Iam working on high perf servlet that needs to return the response within few seconds and hence I want to emulate an non existant connection rather than a delayed response i.e. the webserver break the tcp connection rather than hold the client for delayed response from the servlet. I played around with the connection timeout parameter in server.xml as well as the timeout directive in httpd.conf for apache without much success. Iam running the apps on redhat 8 on intel platform. How should I approach such a thing? Apache 2.0.47 tomcat 5.x JK 2 Thanks sameer This message contains confidential information and is intended only for the individual named.

Tomcat behavior
Hi Folks , I have a question Folks : Does Tomcat Processes become 0 at some point if Web Application is not accessed for a while. What has happened is twice in our environment that on a Weekend Morning around 2:00 AM Tomcat Processes became 0 and they later increased to 36 processes .I found out it through a small Script that checks for the number of Apache and Tomcat processes every Minute .I found the similar behavior for Apache Twice with Apache processes becoming 0 and then after a while number changing to 8 which is normal in our environment. My question is : Does Tomcat Shuts down and restarts itself at a certain regular interval like once in a month or so .If yes then ,is there any Configuration file in Tomcat from where this can be Controlled.The same question applies for Apache --if Apache shuts and restarts itself at a certain regular interval .

Is anyone using Two Instances of Tomcat on the same server with Formula1 s/w.Guys any help on this will be greatly APPRECIATED. Configuration : Red Hat Linux 7.0 Apache 1.3.12 Tomcat 4.0.4 -Two instances i.e tomcat and tomcat2 Regards Sameer -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
Two instances of Tomcat
Hi Folks , Need some urgent help regarding setting up two instances of Tomcat .Here goes the details .We used to have Apache 1.3.23 + Tomcat 4.0.2 configuration running on Red hat 7.0.We were running two web apps under Single instance of tomcat. To make them independent we are moving towards Two instances of tomcat .So we installed second instance residing in /opt/tomcat2 directory ,first being in the directory called /opt/tomcat.Changes on server.xml were made for two different port nos.Now Everything works ok till the point when we try to generate a report in second web application it gives a Java.lang Out of Memory error.This Final report feature uses the Formula 1 Software which is a e-spreadsheet.Can any one please tell me what all settings are required for the TWO instances of tomcat.do we need TWO copies of Worker.properties files (Coz we have only one ) and if yes then what changes need to be done .Is the Java error related to JVM memory settings .We have set TOMCAT_OPTS in /etc/profile for -Xms64 and -Xmx512.

tomcat webdav question
Hi, I am not sure where to send this question, I guess here would be a good starting point. Is it possible to configure the webdav servlet in tomcat to get files from a new filesystem, which has a java api to access files, rather than the local filesystem or an an nfs mounted file system. Slide is supposed to do something like this, but it has much more functionality than what is needed here which may make it hard to integrate. The filesystem that webdav would need to support is implemented through a mysql server, and with its own acls. So the webdav servlet would also need to use a mysql table for authentication which could be implemented through a tomcat jdbc realm. How should I go about it?, Do I need to completely hack the webdav servlet, and implement the new filesystem code there, or is there a simpler method, and if this is not the right mailing list which other mailing lists should I send this question to. Please let me know. thanx, sameer. __ Do You Yahoo!? Yahoo!

Problem in loading applet.
Hi All, I am trying to use Tomcat as a standalone web server. I am not able to get Applet working with this setup. I bascically have a webpage with applet tag in the html loading a class from an archive. Then the applet reads some gif files. If I copy the jar file in the Root directory of Tomcat, the place of the applet comes as blank. But the status bar in the browser says 'applet loaded'. If I remove this jar file, the browser returns an error that the class is not found. Is there any basic setup I am missing? Where should the gif files the the applet reads be present? Thanks in advance, Sameer

NoClassDefFoundError
Hi, Just installed Tomcat according to the instructions given in the Development/Deployment guide give at http://jakarta.apache.org for Tomcat. When I say ./build, I get an error "NoClassDefFoundError org/apache/tools/ant" I have not installed Ant (if that is something to be installed - I believe it is pre-installed) and neither have I used CVS as www.sourcegear.com/cvs is down. I hope it is not essential to use that. What could be the problem? Thanks in advance. Regards, Sameer Kachroo - Original Message - From: "Miles Daffin" [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Friday, November 24, 2000 3:48 PM Subject: Re: News Group needed desperately Dear Craig, See below. Miles Daffin wrote: (I did) I have been on this list for a week or so now and I am flooded with mails everyday. When this happened on the Orion Interest list I had no choice bu to unsubscribe. The sheer volume of mails (50% of which ask ill considered questions) suggests the need for a news group, maybe two. The virtues of doing it like this are numerous, e.g. threads can be viewed, followed etc. It simply organises the mails better, allowing me to filterwithout cluttering up my system first. Who can set this up? Craig (I know you are a busy fella)? Miles Yes, I am busy :-), but that is not why I'm not likely to act upon this request. None of the virtues you mention are compelling reasons to establish a newsgroup. After all, many mail readers (including Netscape Communicator, which I use) can do exactly what you ask for. For example, I have a message filter set up that copies all messages with a "To" or "Cc" of [EMAIL PROTECTED] into a folder containing only those messages (actually, I have one of these folders for each of the 30 or so mailing lists I subscribe to, totalling over 600 messages a day). Netscape, like most mail readers, allows you to specify a threaded organization for such a folder, which is my default approach to dealing with mailing lists. Now, I can concentrate on a particular list when I want to -- *exactly* as if it were a newsgroup. What is more important, though, is a different principle -- having a newsgroup instead of a mailing list would disenfranchise all of the TOMCAT-USER subscribers who are behind firewalls that do not allow access to newsgroups. Therefore, I do not consider this to be a viable solution to mail "floods" -- if your mail reader doesn't support what you need to deal with mailing list volumes, I would suggest that you get a new one. Your words are wise and true - I see the light and shall complain no more. Craig McClanahan Miles Daffin
