RE: Tomcat forgets a session attribute when reloading context
It's possible that your User object is not serializing correctly. As I
understand things: when contexts are reloaded, the sessions are serialized
first, the context reloads, and the sessions are restored from their
serialized form. If one of your attributes doesn't make it through this
process, then the Session itself is not invalidated; you just don't get that
particular attribute back. I've seen this happen on my own web-app.

Subject: Tomcat forgets a session attribute when reloading context
Hi 'catters. I am having a small but annoying behavior in Tomcat.
Tested on
5.0.28 and 5.5.9. I posted this as bug 34547 but a developer thinks
it's not a bug.
I use Eclipse 3.02 for development, along the Sysdeo Tomcat
Plugin and Freemarker for MVC. My context path is set to be
reloadable, and when i
am
coding, if i make some change to the code, the context gets
reloaded by
the
plugin, and a session attribute gets null'ed.
The weirdest thing is that not all of the session attributes are
nulled. Just
this one we will call user.
I will try to explain what happens with pseudocode.
When the users log on to my application, this happens:
ForumUser user = run_sql_here;
ForumUser is a bean with some properties. That query stores:
-a user id (int)
-a timezone (string)
-a language (string)
All of the other attributes in the object are not used at this time.
session.setAttribute(logged_user_name,username);
session.setAttribute(permission,permissions);
if (user!=null) {
session.setAttribute(userpreferences,user);
}
This is the ONLY time that attribute gets set. It ONLY gets removed
when the
session is invalidated.
When i change code and the context gets reloaded, the user
attribute
gets
null, and the other 2 attributes (permission and
logged_user_name) are
OK
If i don't reload the context, everything is OK.
Does anyone have any idea of what is going on?
Do you guys need my code? I will gladly do whatever test you
need me to do to resolve this. It is very annoying to keep
logging out and back in
to test
new code so my session gets corrected
Why this doesn't look like a bug? Tomcat deletes an object in my
session. If it would delete all objects,
then i wouldn't have posted this, since i would have thought that
reloading a context would delete the whole session.
I think my code is ok since i just set that attribute (the one that
gets null) at login.

RE: Trying to understand exceptions and error-page
Part of the spec says if no error-page declaration containing an
exception-type fits using the class-heirarchy match, and the exception
thrown is a ServletException or subclass thereof, the container extracts the
wrapped exception...
So supposing for a minute that Tomcat internals ignore any error-page that
has exception-type 'ServletException', it would then proceed to unwrap the
exception to get down to your DAOException. Which you've already proved that
you *can* catch.
I've successfully caught 'all other' exceptions (which I suppose must
include ServletExceptions), by using one error-page declaration that catches
status-code500/status-code, and then multiple exception-type's to
catch more specific exception types.
This is all on TC5.0.28 (TC4.x seemed a bit flakey on exceptions and
errorpages, but that could have been PEBKAC)

RE: How does Tomcat know that a browser supports cookies?
So you're saying that you've seen Tomcat *not* rewrite URLs in a response to a first request from a client that *does* support cookies, and *does* rewrite the URLs in a response to a first request from a client that doesn't support cookies? That would indeed be very powerful software. Tomcat needs at least one request/response cycle to be able to determine if cookies are enabled or not; which it does on the subsequent request/response cycle. Your request comes in. You have no cookie (either because you don't allow them, or it's your first visit this session) Tomcat responds with a session cookie, and if you've run URLs through that method, URLs are rewritten too. The next time you request something, your browser sends back the cookie (if you allowed the cookie). Tomcat sees this cookie, and then stops rewriting URLs. If your browser doesn't send back a cookie with the next request, the method continues to rewrite URLs. My only doubt is: Does it continue to also send the cookie in a 'faint hope' that it might one day be accepted? This could be easily investigated with liveheaders in firefox. Come to think of it, liveheaders would help you confirm what I've just said. ;) Mike Curwen -Original Message- From: Harry Mantheakis [mailto:[EMAIL PROTECTED] Sent: Thursday, January 27, 2005 10:12 AM To: Tomcat Users List Subject: Re: How does Tomcat know that a browser supports cookies? I understand what you are saying, Javier, if you have a round-trip situation, where you set cookies in one response, and then test for them in a follow-up request. But I'm not convinced that's how Tomcat does it. The first time a client connects to a server, there will not be any cookies, session or otherwise, for the client browser to send to the server - but Tomcat can still figure out whether or not cookies are enabled in the client browser. At least, that seems to be the case with my application: Tomcat automatically decides whether or not to apply URL rewriting if I call the HttpServletResponse.encodeURL() method. I wonder if anyone here knows for sure? Regards Harry I use a HttpSession object. HttpSession object = null; When user access to site, i use: object = request.getSession(); later i use: boolean n = object.isNew(); if n = true, then user is not using cookies. I suppose that tomcat is using Session Cookies and not re-writting politic.. because, tomcat keep session with user using cookies, so.. if session is new mean that user is new for tomcat, because it can't send cookie. regards.. Javier At 10:12 27-01-2005 +, you wrote: The API for the HttpServletResponse.encodeURL() method states that the implementation of this method includes the logic to determine whether the session ID needs to be encoded in the URL. How does Tomcat know whether or not a browser supports cookies, or session tracking is turned off? Is it simply a case of looking for the presence of a Cookie: header in the request, and assuming that cookies are enabled if the header is found? And if that is the case, would I be correct in assuming that browsers (when permitted by their users) will set Cookie: headers in their requests even if they do NOT actually have any (previously set) cookies to send back to the server? I'm just guessing, of course - and I know I should not generalise about browsers: I'm thinking of IE, Mozilla/Firefox and Opera.

RE: Tomcat and Sesssion question
Yes, you would still have needed to send your links through one of : HttpServletResponse.encodeURL() or HttpServletResponse.encodeRedirectURL() (which is a fairly good practice anyways). Your other option is to spend a bunch of time coding a javax.servlet.Filter that wraps the response, then parses through the response, and re-writes the links for you. iPlanet (yes, I'm an iPlanet survivor) was able to do this long before Filters, with mixed success.

RE: reload log4j.properties on-the-fly?
Right, so you want to configure *tomcat* logging on the fly, but not a web-app's. The scenario might be: Production box with Tomcat logging set to ERROR starts behaving oddly, perhaps throwing a lot of ERROR level messages. To help diagnose, you want to dynamically enable more verbose logging (WARN, INFO) for *tomcat* logging. Hmm... Tomcat uses commons-logging, so there'd need to be a way to get commons-logging to reload its configuration. I stay away from commons-logging as much as I can, so no help from me. But if Tomcat doesn't already support it, then you're looking at tweaking tomcat source to get what you want, and that's if commons-logging lets you do it. p.s. to Julius: Both of your suggestions are just TOO easy... and here I've been afraid of looking into this.

RE: Tomcat 5.0.28 running Windows 2003 Server CPU to 100%
Every so often in our development environment, we'll have a page that goes
off in an infinite loop. No problem, we'll just stop the browser, and fix
the page and click refresh. But meanwhile, that first page is still
spinning away, gobbling up CPU.
I once saw code on tomcat-user that allowed me to see what each thread was
doing. It's at the very bottom of this post:
http://marc.theaimsgroup.com/?l=tomcat-user
http://marc.theaimsgroup.com/?l=tomcat-userm=109455426721082w=2
m=109455426721082w=2
I must have found the 'second part' from somewhere else, probably
tomcat-user as well! It's a filter that renames the thread to be the JSP
page that the thread is processing:
public void doFilter(ServletRequest servletRequest, ServletResponse
servletResponse, FilterChain filterChain) throws IOException,
ServletException {
Thread t= Thread.currentThread();
String oldName = t.getName();
HttpServletRequest request = (HttpServletRequest) servletRequest;
try {
t.setName(oldName + - + request.getRequestURI());
filterChain.doFilter(servletRequest, servletResponse);
} finally {
t.setName(oldName);
}
}
combining those two, and you'll get what page is currently processing on
what thread. If you see the same page for more than (the time varies,
but let's say 10 seconds)... then perhaps that page is 'dead' and is
consuming your CPU.

Subject: Tomcat 5.0.28 running Windows 2003 Server CPU to 100%
Can anyone point me to a thread discussing the following configuration or
something similar, where the discussion relates to the CPU running up to
100%?
Windows 2003 Server Standard Edition running IIS 6.0
Tomcat 5.0.28 installed and running (as a service)
SQL Server 2000 SP3 connected to Tomcat (and IIS), but running from another
server.
Our symptom is that after a few days the server CPU usage hits 100%, with
Tomcat consuming most of it. Stopping and restarting each Tomcat virtual
site, or stopping restarting the Apache service does not resolve the
issue. Only a box reboot will.
I need some guidance as to where to suggest to the developers they should
look, presuming this is caused by the code. I am the system admin of the
environment and so do not develop the code myself, but I am seeing this
symptom and now need to ask the developers to examine their code to find a
root cause.
I bet someone, somewhere, has run across this on a thread on this forum and
can point me to it? I've been searching some but have not found much yet
that is recent.

RE: Tomcat lost request parameters
I once worked on a portal site that experienced very odd behaviour under load. When in development, everyone got what they were expecting. Under load testing, pages where missing items, some items were duplicated, etc, etc. The problem was the usage of variables in a JSP page declared in: %! % or the corresponding type of variable (instance variables) in servlets. It doesn't show up under normal load, because individual users can get in and out without anyone being the wiser. Once the container starts getting loaded though, you can have person A's request not being completed before person B's request is begun processing.

I always used tomcat as my web server (without apache because I don't have static html to be served) with no problem. We are using TC 4.1.31, with J2SDK1.4.2_03 on a W2K/SP4 box (Xeon 3.0Ghz with 2GB mem). At this time we had more or less 25 concurrent users. We were happy... Recently, another department in company started to use the application. So now we have more or less 100 concurrent users. Since then the problems began raising. Most of then when we try to insert/update data in database. Generally we receive errors telling that we tried to insert null values into a not null field (BTW we are using oracle 8.1.7 with JDBC - classes12.jar). My point is that application was working. Nothing changed (except the number of users). So, I'm sure that the fields are being properly filled. What I would like to ask you, is if someone has experienced this kind of problem.

webapp's log4j config acting wonky
Hi all,
I've been using log4j for some time and like it quite a bit. My configs are
probably naieve, but they work for me. But now, another developer has
pointed something out to me, and yup.. something's busted. I'm posting this
to tomcat-user because I'm thinking it might be a TC/mywebapp conflict of
some kind (though I'm not sure where).
Tomcat 5.0.29
log4j 1.2.1 in my webapp's WEB-INF/lib
log4j.properties in my webapp's WEB-INF/classes directory.
I don't have log4j.jar anywhere else and no other log4j.properties files
anywhere, though perhaps I don't know where to look.
In our JSP pages we have loggers declared like so:
%@ page import=org.apache.log4j.Logger %
%!
Logger logger = Logger.getLogger(pages.abc.page_name);
%
%
logger.debug(foo);
%
pages is common throughout every JSP. abc would be a folder name (we've
got the webapp organized into folders of related functions), and finally
page_name is the name of the JSP file without extension.
our log4j.properties file is:
#log4j.properties
log4j.rootCategory=DEBUG, filer
log4j.category.com.gb.security=WARN, filer
log4j.additivity.com.gb.security=false
log4j.appender.filer=org.apache.log4j.RollingFileAppender
log4j.appender.filer.layout=org.apache.log4j.PatternLayout
log4j.appender.filer.layout.ConversionPattern=%-5p %c - [%m] %d{ISO8601}%n
log4j.appender.filer.File=/path/to/the/log/file/debug.log
log4j.appender.filer.MaxFileSize=100KB
log4j.appender.filer.MaxBackupIndex=4
As you'll see we've got the root category to DEBUG and we've piped down our
com.gb.security package to WARN. We've got lots of other classes, both
bundled in WEB-INF/lib jar files and loosely in the WEB-INF/classes and
they all spill their log4j output.
But none of our log messages from the JSP pages are coming through. I've
tried the following config, but it had no effect:
log4j.category.pages=DEBUG, filer
log4j.additivity.pages=false
*If* I configure the following (adding a 'package' below 'pages'):
log4j.category.pages.abc=DEBUG, filer
log4j.additivity.pages.abc=false
Then it will work (but obviously only for pages under 'abc'). Also, if I
remove the additivity, I get two messages. That makes me think there's one
message from the rootCategory, and one from this category. But when I
remove the category 'pages.abc' entirely, we're back to nothing again.
Any ideas? Is there a TC log4j or CL file hiding somewhere?

RE: webapp's log4j config acting wonky
Fixed!
The first thing I tried was to remove the log4j.properties file from
WEB-INF/classes and restarted TC. It was still logging! and what's more, it
was logging to the file I had specified in the since-removed
log4j.properties file. So, there is only one other app on the same TC
instance; a copy of the first app. I removed its log4j.properties file as
well. Both apps on restart were still logging! serious wtf!
Shut down TC, blew away its work directory, rm -r'd all over the place...
restarted, and finally got the there are no appenders configured for this
logger message (twice, once for each app).
Brought it down again, upgraded the log4j.jar to 1.2.9 (I was probably
already using 1.2.8 actually), and then did the modifications you suggested
to the log4j.properties as below:
#log4j.properties
log4j.rootLogger=DEBUG, filer
log4j.logger.com.gb.security=WARN
log4j.appender.filer=org.apache.log4j.RollingFileAppender
log4j.appender.filer.layout=org.apache.log4j.PatternLayout
log4j.appender.filer.layout.ConversionPattern=%-5p %c - [%m] %d{ISO8601}%n
log4j.appender.filer.File=/path/to/the/log/file/debug.log
log4j.appender.filer.MaxFileSize=100KB
log4j.appender.filer.MaxBackupIndex=4
Put this in one app, and got one there are no appenders configured... and
one debug.log file in the right location. Put the other app's
log4.properties file in place, restarted, and now my two webapps are merrily
DEBUGing.
I'm getting debug messages that I had forgotten I should have been getting!
Also, thanks for the info re: loggers and additivity.

RE: Display of Static Resources
you've named it 'myweb.xml', just so we can tell the attachments apart, or is it actually named myweb.xml? If the latter, change it to web.xml. And having your servlet mapped to / is most likely the problem. The default servlet is the one that Tomcat uses to serve up static resources. So either change your servlet to handle static resources or (way better option), map your servlet to a pattern other than /, and then change your web form accordingly. -Original Message- From: Ram Sriram [mailto:[EMAIL PROTECTED] Sent: Saturday, December 11, 2004 1:10 PM To: Tomcat Users List Subject: Re: Display of Static Resources Ben, I removed all my application specific entries in web.xml under conf and moved those to the web.xml under ROOT\WEB-INF.

RE: Moving from 4.1.27 to 5.0.28?
We've recently been writing the 'next version' of our main application, and the decision was made to target TC 5.0.x, up from 4.1.x. We experience no major difficulties in making that move, thouogh there can be a few gotchas. The one thing we noticed that changed (for the better) was error page handling. Others have reported small problems regarding TC 5's more strict interpretation of the spec in certain areas. As an example of this (though this is from memory!) I think someone had something like: jsp:include page=foo /jsp:include And that appealed to their sense of 'good coding' (like putting opening and closing braces on all blocks, including one line blocks). This worked in Tomcat 4.x, but not in 5.x So small things like that might catch you up, but otherwise nothing major. -Original Message- From: Bjørn T Johansen [mailto:[EMAIL PROTECTED] Sent: Wednesday, December 01, 2004 7:08 AM To: Tomcat Users List Subject: Moving from 4.1.27 to 5.0.28?

Virtual Hosts and useCanonical
Yup, I've asked about/commented about this before. I'm having trouble with Vhosts, server names, and how to get the value I want out of request.getServerName(), and this is all with apache/jk/tomcat.

I'm only get the canonical name, help me get the alias http://marc.theaimsgroup.com/?l=tomcat-userm=108315928213678w=2 I don't care about alias, get me canonical. http://marc.theaimsgroup.com/?l=tomcat-userm=106095508818371w=2 So I know that both of these seem to have worked (or been doing a good imitation of it). But now, for the life of me, I can't get request.getServerName() to return the canonical ServerName from httpd.conf. apache's httpd.conf -- VirtualHost 139.142.220.45:80 UseCanonicalName On ServerName devstar.myhost.com ServerAlias www.devstar.myhost.com DocumentRoot /home/data3/me20 Location /WEB-INF/ AllowOverride None deny from all /Location JkMount /*.jsp tomcat1 JkMount /login tomcat1 ErrorLog /var/log/test/error_log CustomLog /var/log/test/access_log common /VirtualHost tomcat1's server.xml -- Host name=devstar.myhost.com debug=0 Aliaswww.devstar.myhost.com/Alias Context path= docBase=/home/data3/myhost/ etc... When I type in http://www.devstar.myhost.com , I was hoping that request.getServerName() would give me devstar.myhost.com (without the www). But it doesn't.

RE: API docs for Mysql JDBC Driver?
Ok, those docs are way out of date. If you're using connectorj 3, those docs would only confuse the matter. The current docos on the jconnector portion of the mysql.com website contain all the latest info on how much of the spec the jconnector drivers implement. The JavaDoc for the drivers themselves (and it's hard to see when you'd want those, unless you intend to bypass java.sql) you can create from the java source files that you get when you download the binaries + source downloads from mysql.com (or don't bother generating them, and just read them from the *.java files). If you're asking yourself: how do I do SQL with jconnector drivers, then I think what you actually want to look into is how do I use the java.sql classes to do SQL, for which there is a healthy amount of JavaDoc included with the JDK, and a JDBC tutorial on java.sun.com.

RE: performance problem
Hmm... http://www.greenfieldresearch.ca/technical/jk2_config.html Reading that, look for the one line in red font. Seems there's potential config problems when apache and tomcat are on separate boxes, as they need to share a file. You'd think this would prevent operation, rather than slowing it down , so perhaps it's not related. We use similar architecture, but JK (which doesn't seem to require that shared file). -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Friday, September 17, 2004 2:06 PM To: [EMAIL PROTECTED] Subject: performance problem I have an apache/tomcat environment that is experiencing performance problems.

RE: How to create/run a Java Service on UNIX
I think we should assume that 'the program' will function correctly and do what it's advertised to do, since if that was the actual problem, then a list like 'java-rmi-user' or 'java-io-user' would be more appropriate. The tomcat application, and that second application should be coded to handle the cases when 'the program' is not available. If that's still a problem, refer to the aformentioned, fictious(?) groups. All that remains is how do I get 'the program' to run? Oddly enough, that's still not tomcat-user, but hey we like to help out. For that (as Yoav said), you need a *nix admin type person to write some rc scripts for you, or investigate how to do so for yourself. Find a BB or other email-user list for the exact flavour of *nix you are running, and ask about rc.d scripts on that list. (rc.d is the approximate equivalent on *nix, of the Windows Services control panel). -Original Message- From: John Najarian [mailto:[EMAIL PROTECTED] Sent: Friday, September 10, 2004 2:28 PM To: 'Tomcat Users List' Subject: RE: How to create/run a Java Service on UNIX Hi Daxin, How are you going to genereate the keys? Via the database? Also, seeing as you are going to use 'service' with without Tomcat I'd like to know if either application will be up as long as the server(s) is up. If that's the case you could have both applications check at startup if the daemon is active(running) or not not. If the daemon isn't active either application could start it. If this service should be up whenever the hardware is up you could start the service on boot so it is in theory always available to the 2 applications when they are started but each must check if the daemon is running prior to accessing the daemon. The person who recommended learning daemons was entirely right and without my knowing more of the 2 applications I can not tell you more except since tomcat will access he daemon, I would look closely at the framework in Jakarta to see if it will suit both applications. I haven't looked at it closely and it Tomcat must be running for the daemon to be running(which I doubt) I wouldn't utilize that framework. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: SOLVED: How to get the context path for a web application?
I'm never sure why smart people get this confused. ContextPath... has nothing whatsoever to do with running in a WAR, from a database, or exploded from a file system. For simple little things that an application might want to do like, oh, I don't know... reminder emails that might contain a link to the webapp in question. At that point, there is no request, since this is probably a scheduled occurrence. I suppose rather than use a scheduler, I could use cron and wget to hit a URL, in which case, voila, I'd have a HttpServletRequest. But wouldn't it be great if you could do application.getContextPath()? But alas, the expert group feels the answer is 'no'. Fine, whatever. It seems ridiculous that the application should not know anything about who it is, or under what URL/I I'm running or however you want to think of it, until an HttpRequest arrives on the scene. I just couldn't let it pass without pointing out that the one (contextPath) has nothing to do with the reasons that are normally cited for its exclusion from anything but HttpServletRequest. -Original Message- From: Ben Souther [mailto:[EMAIL PROTECTED] Sent: Friday, August 13, 2004 9:12 AM To: Tomcat Users List Subject: Re: SOLVED: How to get the context path for a web application?

Also, what's a generic way for doing this across other database, for example, MySql, MS Sql, etc. Also, what if the table does not exist? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: DBCP pool
I think the way to do this with DBCP is to specify a test query. The pool would then run this query (like SELECT 1) before giving out the connection. If it failed (and if it's because the connection is closed), it will null this connection in the pool, open a new connection, and retest it, and then give this one out.

RE: How to start a web app?
Michael, my email was specifically in reply to David.Pawson's. I thought I'd point that out in case you took anything personally in my previous email. I bother to point it out because you asked the same question three times. Where I come from, that's ridicule by repetition, but I could be mistaking your intent. Sarcasm aside, it's an interesting thought process you must have gone through to start off with Right, and then proceed to point out how it's wrong. The point I was attempting to make is that there is nothing wrong with the docs, and that they are not missing Essential Information. Unless someone can tell me how the 3rd bullet on the docs I linked to allows a person to infer recursion, I don't think the docs need changing. Perhaps it's the use of 'subdirectory'. If it was changed to read Any directory within the Application Base directory, would that avoid this miscomprehension? If not, then I come back to my first question of the previous email.

RE: Tomcat Logging.. whats the best way ?
I believe that it's 'normal' to use a logging package, rather than system.out to perform debug logging. A package like log4j has many advantages including: 1) It's popular (so you get support and lots of people can help) 2) It's super-configurable (you can turn each class/package on or off, or adjust its logging level) 3) It's not system.out (which may not always be under your control) -Original Message- From: Ben Bookey [mailto:[EMAIL PROTECTED] Sent: Tuesday, June 22, 2004 10:02 AM To: Tomcat User List Subject: Tomcat Logging.. whats the best way ? Dear List, We have written a webapp, and now I want to add some logging inside. The app has jsp pages, servlets and a java package of classes for jdbc database interaction. O.k. as I understood Tomcat does support logging via, catalina.out etc. The logfile can even be configured based on each web descriptor web.xml file. This seems quite flexible until you want to start monitoring whats going on inside of the com.package, not just inside the servlet container. So it seems to me that we need to create/use a logger class (e.g. log4j) for the package. Am i right in understanding that its normal-case to use a log4j type method of logging denug info for internal purposes. Its not recommended to use JUST Tomcat logging for the complete web app.? Would appreciate any view, regards BB - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
