Re: SessionListener invoked sometimes and not others
My web app has two servlets. One JSF Faces servlet and another servlet for processing AJAX requests from javascript. I want to know when the app starts and when the app is done. Is the only way to do this is to have a ServletContextListener listening to both those servlets? On the first one, I get resources and on the last one being cleaned up, I destroy the resources. I guess this works. I just wish I had access to the app lifecycle. thanks, dean Mark Thomas wrote: From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] So after a restart of tomcat, I login and it appears the session is still valid, so it does not go through my session listener.

Subject: bug in 4.1.30?? PageContextImpl hides exception cause
In 4.1.30, In PageContextImpl, I see this code (should I post this on the
dev list instead)
525 if (t instanceof IOException) throw (IOException)t;
526 if (t instanceof ServletException) throw (ServletException)t;
527if (t instanceof RuntimeException) throw (RuntimeException)t;
528if (t instanceof JspException) {
529Throwable rootCause = ((JspException)t).getRootCause();
530if (rootCause != null) {
531throw new ServletException(t.getMessage(),
rootCause);
532} else {
533throw new ServletException(t);
534}
535}
536 throw new ServletException(t);
537 }
538}
Notice on line 533, the root cause is correctly chained. Unfortunately,
when the exceptions print out, t is not printed and I don't know what
really happened. This is quite annoying. It takes 27 steps to build tomcat
4.1.30 so I wasn't quite interested in investigating further. If it took 3,
I would probably be posting a fix because I would know more by now.
thanks for any help here, The full exception chain is shown below. It is
obvious there is an exception missing from this stack trace from looking at
the code of JspServletWrapper and PageContextImpl

many java processes
On linux did anybody ever get a linux patch for fixing the problem of one process per java thread. I read on the sun bug parade they were going to port to a new threading model but we needed to update the linux threading I have seen many e-mails complaining about how tomcat creates s many processes and this is due to a JVM thing not tomcat. Does anybody know or is everyone just sitting by with many many java processes on their linux?

maxProcessors
excuse me in my ignorance, but it has been a while and I have forgotten how webservers work. How does a typical webserver work as far as a few threads waiting on accept() for incoming connections? Is the socket created/teardown every time a user goes to a different page? Now that the basics are out of the way, what is maxProcessors for?

Re: apache + mod_SSL + tomcat
I think there is a way to solve the problem without shutting down port 8080. Someone please verify this is true. If I use a servlet, my servlet can determine if the connection is from 8443 or 8080 and if it is from 8080 can deny the user access right away. Is this correct?

Re: apache + mod_SSL + tomcat
In my app, we don't need everything to run over SSL and we are not using apache so we only have ports 80 and 8443. I changed the default 8080 to 80 and should have probably changed 8443 to 443. When SSL is not necessary, we don't use it as it slows down the downloading of the pages.

Re: Init method of servlet called twice?
I remember dealing with problems like that before but they are vague in my head. Your problem is better posted on the java forum I think. I am trying to recall what happened. It was something like I would hit back in my browser and then forward so IE would call init again. I remember having many problems with this and netscape and IE behaved differently.

Re: apache + mod_SSL + tomcat
I thought tomcat was on 8443 by default. Are you sure you are pointing at tomcat, or do you have another webserver running on port 443, since that is the default that most webservers use when starting up. tomcat is the exception running on 8443 thanks, Dean -- To unsubscribe: mailto:[EMAIL PROTECTED] For additional commands: mailto:[EMAIL PROTECTED] Troubles with the list: mailto:[EMAIL PROTECTED]
Advanced Ques. w/SSL
I have done the HOW-TO on SSL and it works fine with stand-alone tomcat. I am preparing an installation of tomcat to be installed on many computers. I CANNOT create a separate certificate for each computer. Am I screwed Our installation program installs tomcat, and then changes server.xml to enable SSL, and how do I deal with the certificates(I mean not self-signed ones). What do I do in this circumstance? I need one certificate on every tomcat installation but this is not possible Any ideas on any of this. thanks Dean -- To unsubscribe: mailto:[EMAIL PROTECTED] For additional commands: mailto:[EMAIL PROTECTED] Troubles with the list: mailto:[EMAIL PROTECTED]
applet works, https doesn't
I have an applet that connects back to the server on 8443 and it works fine even without a certificate. When I go to https://localhost:8443 web page, I get a prompt with an unknown certificate(certificate was created and self signed by me). Why don't I get this prompt with the applet, it is using port 8443? Something is questionable here.

help with installation
Hello, I installed apache_1.3.19-win32-no_src-r2.msi on Windows 2000. putting the ServerName as localhost, this worked fine and I could open http://localhost web page. I than installed jakarta-tomcat-3.2.1, and this seemed to go fine, and I could see http://localhost:8080 web page. Than I downloaded ApacheModuleJServ1b3_136.dll, and put this in the modules directory of Apache. I than made sure tomcat and apache were both stopped. I added this line to apache\conf\httpd.conf Include c:/Program files.tomcat/conf/tomcat-apache.conf I than started up tomcat first, as that file from what I understand is generated from server.xml, NOW when I start apache up, it gives me errors on 2 lines. ApJServDefaultProtocol ajpv12 ApJServLogLevel notice Why I am getting errors here?? If I comment them out, apache seems to run fine, but since this file is generated from server.xml, I can't just keep commenting them out every time after starting tomcat which will happen very often because I am doing some tutorials.
