RE: Tomcat and the HttpServletRequest Object
The recognition (and so far, little acceptance) that form fields will not be sent in a guaranteed order by a browser, and never mind that, because even if your browser does, the container doesn't guarantee an order either... is from Beginner's Servlets. But maybe I only think that because the vast majority of my time in servlet/jsp development has not been spent with a container that has this nice enhancement. If you *output* the fields in a determined order, then it seems clear that you could also do something like name=%= index %_restOfName. Hackish, brutish and stupid as it might seem, to those that have not drunk the koolaid, I think it (or something like it) is a time-honoured tradition for most people that already understood this (the aforementioned koolaid drinkers).

RE: Problem for loading files under WEB-INF/classes
You might consider the following: 1) if you wrote log4j.properties on one platform and uploaded it to another, perhaps the format got mangled. Check to be sure that log4j.properties is actually log4j.properties, without some special, non-printable and hidden character on the end of the filename.

The SFTP client didn't show them, but if you logged into a shell and ls -l, you'd see the ~. 2) check *inside* the file for things like line return nonsense (CRLF vs. CR vs. LF) and gibberish characters. 3) check that log4j.properties has the correct file permissions (it's owned by the correct user/group).

Usage of DBCP in Tomcat
Hi everyone, The number of sites we support has recently expanded, and we're starting to run into db connection errors : we are running out. Mysql currently has its default max (somewhere around 100?), and I'll be scheduling a restart to increase this count (as an aside: anyone know how to up the connections on a running mysql server?) But I'd also like to find out why the DBCP configuration that I have is not functioning as expected. Is there something I'm missing or not understanding?

Also remove a connection if it hasn't been used for more than 15 seconds, and tell me you did that. All the websites share this common config. I'm getting single websites maintaining up to 20 connections. When I examine the mysql instance with the GUI MySql Admin tool, I see pretty much all of them in SLEEP and for well over 5000 seconds, never mind 15 seconds. Perhaps I'm leaking connections, which I'll be investigating as well, but then why aren't they being reclaimed as abandoned? If I don't configure timeBetweenEvictionRunsMillis, will the number of connection in the pool ever be reduced to maxIdle ? Is the autoReconnect screwing me?

Re: Apache Tomcat Conf Help
John thanks for reply. I get wierd results when I do this, i think it is because i have an odd setup going. I have manually written the mod_jk.conf stuff and inserted it into my apache conf (seen below). The reason I did this is couldn't figure out how else to get my tomcat context working with ssl. When I make the change you suggested the images directory off the domain mydomain.com/images is not viewable for some reason. Also tomcat seems to be mixing up that root directory with the docs i can't quite explain it. I assume it is because of a mismatch in my conf file. I think your suggestion won't work because the rest of my conf is screwed. So let me start from scratch my ideal set up is to have http://www.mydomain.com and https://www.mydomain.com both go to https://www.mydomain.com/ and this should be my tomcat context. Do I have to use apache proxy directives to accomplish this? What would be the best way to go about this when using apache tomcat?

RE: Memory/Performance
. In summary: in real-life use, the abstraction of a session provided to jsp writers by Tomcat and other web containers is going to work perfectly fine, with no resource compromise. Your well-designed application already needed those resources stored in the session anyway. Sessions only add a few more references/pointers (at 4 bytes a shot - cheap!) to those resources. Over 99% of browsers support cookies. There are no hidden dangers with sessions. Now, onto the rest of email. I assume session.invalidate() kills a session. How and in what situation would I use this method? Use it on a logoff.jsp. Inside logoff.jsp just paste: % session.invalidate() % I assume my sessions are closed automatically by tomcat when there is no usage from that client for 15 minutes. That is correct. Tomcat probably calls invalidate() just like you would on a logoff.jsp page. Code re-use. :-) What does setMaxInactiveInterval do and how is that applied? You could use this to override the 15 minute application-wide timeout you've configured on a per/jsp or per/servlet basis. For example, maybe you would like to set you login.jsp's session timeout to 2 minutes, but after the user successfully logs in set it back to 15 minutes. This way people who fail to login, or don't bother trying, use up less session resources. However, once you've set the session to 2 minutes on one page, it's going to stay 2 minutes unless you state otherwise somewhere else. I imagine that would work. I wouldn't bother messing around like that, though. Too finicky. Buy a 2nd server and cluster them. :-) And same questions on response.encodeURL()? This only applies if you're not using cookies. But it's not a bad idea - makes your application more portable, since the cookie/no-cookie configuration is administrator controlled, not developer controlled. Basically you run every internal link (to other jsps or servlets) through encodeURL(), et voila, sessions without cookies if ever needed. I haven't used this, so my explanation here may be a little fluffy. Tomcat starts out with 128 megs and baloons up pretty quickly to 300 megs. It often exceeds that, there also seems to be a huge thread count. Perhaps you have a thread problem (yikes!). My experience with threads and Tomcat is very minimal, but in my experience threads use a lot of memory. I believe they keep references to their entire call-stack (methods calling methods), and so when they hang a lot of references remain unavailable to the garbage collector. Don't worry about Tomcat: in my experience on this mailing list Tomcat's thread usage is perfect. It's always developers that mess up. Don't feel bad if this is the case. You only get good (err... marginally less dangerous) by screwing up several times. I almost took down a medium sized financial institution's website I was developing due to some shoddy thread work. Debugging multi-threaded apps when the threads go bad is fun in a way. The thing to remember with web applications is that each request, from start to finish, is going to need a thread. If the thread gets lost somewhere along the way, it's not coming back. Some tricks that seem to work for me (see what Tomcat-User thinks): Don't use wait() when you can use wait( 6 )! At least you'll recover the thread a minute later. Don't use notify(). Use notifyAll() instead. In my opinion wait(void) and notify() are not meant for mortals. Especially not in conjunction with web applications. Good luck, ryan! Hopefully we can help you fix your website, and help Tomcat conquer the world! It would be a good idea to try and isolate your problem. Can you get the memory usage to balloon up during a simulation in a test environment? Of course, you're probably frantically trying to fix your production site... in which case banging out fear-inspired fixes can also work quite well, too. I do envy your close proximity to such a respectable load on your computer. I wish I could see what my own code would do at such use.

Re: Memory/Performance
Thanks for your comments. Well all my jspcode is definitely session happy and I am creating several objects per session. The objects I am creating consist of mostly string, int and floats, probably up to like 20 of each. Although i create a large application pool of jdbc connections I am fairly positive that this is not the problem because I use this pooling model in several applications that don't seem to have a problem. I realize that every time a session is created all these objects must be allocated, and that should cause the memory blob to keep growing as the session count increase but I would think the memory stamp would correspondingly shrink when all these sessions are closed and it doesn't. I am basing this on tomcats crashing or slow behavior in conjunction with monitoring the processes and memory usage. What other information can I share that would help? Like I said I don't know if this is tomcat or me or a bit a both so I am jsut throwing out what seems to be going on and looking for insight?

I was just thinking about what you were saying, especially [...] I would think the memory stamp would correspondingly shrink when all these sessions are closed and it doesn't. I noticed this section in the default web.xml: !-- Default Session Configuration = -- !-- You can set the default session timeout (in minutes) for all newly -- !-- created sessions by modifying the value below. -- session-config session-timeout30/session-timeout /session-config So, by default on my machine sessions will stay around for 30 minutes, unless either session.setMaxInactiveInterval() or session.invalidate() was called. I haven't changed this file since I installed Tomcat, and so I'm assuming you have the same file. Are you calling either of those methods - invalidate or setMaxInactiveInterval? Or when you say these sessions are closed, do you mean they time out after 30 minutes? Secondly, what are you doing to generate all this (server-crashing!) load? Obviously you're not going to call session.invalidate() on the same page that you created the session. That would be pointless... so here comes an interesting possibility: suppose a significant portion of your load didn't support cookies? Or, if you were using URL rewriting for the sessions, suppose you forgot to use response.encodeURL()? In both cases the result is the same: Sessions are being created for a client, but the client won't remember his special session id. This means a new session is created for this client with every request he makes! So, I have three questions I need to know: 1.) What kind of load is Tomcat experiencing on your machine, and where is this load coming from? 2.) Does your load support cookies? Is the session id being remembered by the client? 3.) How are you closing your sessions? Suppose each of your sessions weighed in at 512 bytes. If your load, at, let's pretend 10/hits second, didn't support cookies, you're going to need ~15mb to hold on to 30 minutes of sessions before they start expiring. This is because each hit is going to create a new session. Tomcat User please correct any mistakes I may have made here!

RE: Class Path and New Context
WHen I take some of the classes that don't seem to be getting loaded and put them in a package they seem to be fine.

Which connector to use?
I am upgrading an old 3.2 tomcat and apache implementation to the new 4.1.12 and apache 1.3.27. This is running on a linux box with the latest 2.4 kernel.

Try commenting out those lines, and see what effect that has. Are those the last lines in your conf file? Maybe you've got a different problem somewhere else in your conf file, and it's just reporting it there because it's the last line. The error message (are you still getting the same one?) indicates it's something related to virtual hosts, so that would be a place to focus.

SSL for certian files wrt a webapp
Hi, How do I make only certain webpages SSL-ified ? I have setup Jakarta Tomcat to allow SSL on port number 443. e.g., suppose a request is recvd for an index.html page then there is no need for SSL. However when the request is made to some other file(wrt a file system), the requestor should be prompted for a username and password over a SSL connection for access to other htmletc.. files.

Um, okay then how stable is the JDBC/ODBC bridge? As I previously mentioned in my initial posting some bits and peices that I've read suggest that this method of connecting to a DB back end is, or can be, a little dodgy. The comments basically revolved around the premise that the bridge is not capable of being threaded and it is considered by Sun to still be experimental. I got the impression that there is potential for data loss or corruption along with performance related issues. The JDBC/ODBC bridge is not appropriate for use in a multithreaded environment like a servlet container. Also, lots of people have had problems trying to use MS Access (designed for personal desktop use) in environments like this, even with a for-pay JDBC driver. I'd start by choosing a different database. How about MySQL (http://www.mysql.org) ? They have a type 4 JDBC driver. Is this OK in a multithreaded environment ? I guess I really need to know if it is reasonable to use Tomcat to host an environment that relies on this sort of DB connectivity. Adrian [EMAIL PROTECTED] Craig Sriram __ Do You Yahoo!? Yahoo!

Re: Tomcat upgrade on Debian fails..
Two stupid check hoping helps:
1- Check: Tomcat must start first, than start Apache.
(..PoolTcpEndpoint Endpoint
ServerSocket[addr=localhost/127.0.0.1,port=0,localport=8009.)
2- Check your path
(./usr/share/tomcat/work/DEFAULT/examples/webxmlval.txt.)
finally check permission in your tomcat dir. As I see :
..Unable to open log file:
/usr/share/tomcat/logs/servlet-${MMdd}.log! Using stderr as the default.
Unable to open log file:
/usr/share/tomcat/logs/jasper-${MMdd}.log! Using stderr as the default.
.this can be a permission problem...

System crash with Tomcat 4.0.1
Hi, System Spec: I am using a Windows 2000 Local system, where the local is Arabic. I installed Tomcat 4.0.1 using the .exe installer. Moreover, I installed Tomcat as a service. The JDK version is 1.3.1_01 Problem: when I run tomcat as a service. Every thing up to now is OK, but when I open IE and type in the URL http://localhost:8080;. The system reboots without any error or notefication. Then, I stpped the service and used start.bat and shutdown.bat provided with Tomcat. However, the problem is also there. PS: I used a nother machine with the same Spec, the same problem occured. I also tried to call the URL from a nother machine on the LAN. The system that had the Tomcat was rebooted automatically.

Subject: Auto load a servlet
I have a servlet that can be loaded by going to
http://localhost:8080/webstation/servlet/WebStation
The servlet, WebStation.class, is in the directory:
webstation\WEB-INF\classes. WebStation.class calls two other
servlets,
BtmFrame.class and TopFrame.class, which in turn load and display in
a
browser html files from the webstation directory.
What I want to do is have the user enter http://localhost:8080 into
their
browser, and run the above servlet, as if they entered the link
above. Is
there a way to do this? I have tried to use mapping with as many
different
combinations as I can think of, but nothing has worked.
Thanks,
Bret

PLEASE HELP: HTTP Forwarding or proxy??
My system is as below: Internet - Machine1 - Firewall - Machine2 -Machine2 needs to be behind the firewall because it accepts socket communictions. -Machine2 ALSO runs a webserver that needs to be accessed from the Internet. THE PROBLEM - A machine on the Internet CANNOT see Machine2. BUT it can see Machine1. POSSIBLE SOLUTION? - If I use RequestDispatch.forward() that forwards requests to Machine2; will the response come directly from Machine2 OR will it come from Machine2, be passed through Machine1 and then reach the browser from the Internet? POSSIBLE IMPLEMENTATION 1- If the above solution is to write a servlet that listens and simply forwards requests, it will involve setting up a servlet enabled webserver on Machine1. Will this work? How do I write a servlet that maps to the URL: http://IP_ADDRESS/ and takes EVERY request coming to that IP?? and then converts that IP as below. How can I have a servlet that just converts the request - http://GLOBAL_IP_MACHINE1/index.html http://GLOBAL_IP_MACHINE1/servlet/test to http://INTERNAL_IP_MACHINE2/index.html http://INTERNAL_IP_MACHINE2/servlet/test Does anyone have any advice in this regard?
