tomcat hangs
hi tomcat-users we use a tomcat-based application and it runs well and fast. but from time to time (this can be some hours but also some days) the application hangs. if i have a look on the server, it's absolutely not busy (this would be surprising because only about 10 people use the application). because of the many ajp13-log-entries, i thought the jk2-connector could be the problem. here are some log entries: [Tue Jul 13 17:48:19 2004] [error] Error ajp_process_callback - write failed [Tue Jul 13 17:48:19 2004] [error] ajp13.service() ajpGetReply recoverable error 3 [Tue Jul 13 17:48:19 2004] [error] ajp13.service() Error forwarding ajp13:localhost:8007 1 0 [Tue Jul 13 17:48:19 2004] [error] mod_jk.handler() Error connecting to tomcat 3 mod_jk: Error flushing in most of all cases, the application (or tomcat or the connector) can recover itself after some minutes of hanging. can anybody help me? thanks and greetings stefan - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: Exclude images from being logged
Hi, Yes, customize/extend the Valve to ignore requests for certain file types.

RE: NPE in ActionForm where it is not be possible
Hi,
Because Log is not Serializable, you can't put it in the session. So
making it transient is fine. I also saw your reasoning for making it
dynamic rather than static.
Tomcat will save and restore your sessions across server restarts by
default. That includes session attributes that are Serializable. If
the Form was in the session, it will be deserialized: this is not the
same process as reconstruction. So if you choose to stick with this
transient modifier, you will need to check for the log being null before
every time you use it.

Obviously I'm missing something pretty basic. Is Tomcat re-using a
form instance across restarts? I've got pretty much default settings
in Tomcat:
I notice, you define/initialize the instance variable log at its
declaration point.
Humor me: what happens if you initialize log in the ctor?

I've had to look at higher priorities for a couple of days :)
Thanks for the idea. I changed as follows:
...
// private transient Log log =
LogFactory.getLog(ChartWizardForm.class);
private transient Log log; // Logging instance for this class
...
public ChartWizardForm() {
showInactive = false;
altClassMeasOrder = false;
...
outputFmt=;
scaleFactor=;
log = LogFactory.getLog(ChartWizardForm.class); // -- ADDED
INITIALIZATION HERE
}
...
But, still get the NPE :(
I'm defininig the instance variable as transient because Tomcat
complains about saving sessions that contain a private instance
variable
(non-transient) of type Log. I was trying to get my sessions to persist
across restarts. Does that suggest anything?
Thank you again - Richard

Hi, Ok so how do I find out definitively which of the stuffs is going to break? You can't. It'll be the first thing executed that requires disk space after the disk is full. You're thinking about this the wrong way: you must prevent the disk from becoming full. Either buy a bigger hard-drive or control/configure your system to not log as much.

RE: log file problem
Could you rotate the log files Like, on a daily basis, rename whatever.log to yesterdaysdateWhatever.log? I assume that Tomcate would then create a new whatever.log when it was needed. You'd still have to watch your diskspace of course. But you could move off or delete logs that were old. -Original Message- From: Jitesh Sinha [mailto:[EMAIL PROTECTED] Sent: Wednesday, July 14, 2004 10:53 To: Tomcat Users List Subject: RE: log file problem Ok so how do I find out definitively which of the stuffs is going to break?

Load-test to fill the logs, and watch the fireworks. ;) If your OS supports volume management (Veritas VxVM, Linux or HP LVM, etc.) then you can quickly setup a very small, dedicated filesystem to do the test. That should fill up quickly. Yoav hit the nail on the head, though: when filesystem space is low, things can get crazy. -QM -- software -- http://www.brandxdev.net tech news -- http://www.RoarNetworX.com - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: log file problem
The other thing said was 'restart the web server which clears the logs' huh? Who here has a web server that keeps logs in memory or entirely in some type of swap space that is cleared on a server restart? (do you mean a tomcat restart, or a server hardware reboot ?) I'm thinking there might be some other problem, not related to logs.

The reason to do this is to isolate the different stages of encoding/decoding from each other, because there's an encoding/decoding between the JDBC driver and the database, there is one yet again between your JSP and your browser, and there is many times one yet again between your browser and your operating system. You will need to check at _each_ stage to make sure that the characters are encoded the way you think they are. I can state from experience that _usually_ it's not at the database level, however, it's usually a mismatch somewhere else that these problems occur (but they are hard to debug sometimes :( ) Regards, -Mark - -- Mr. Mark Matthews MySQL AB, Software Development Manager, J2EE and Windows Platforms Office: +1 708 332 0507 www.mysql.com MySQL Guide to Lower TCO http://www.mysql.com/it-resources/white-papers/tco.php -BEGIN PGP SIGNATURE- Version: GnuPG v1.2.3 (MingW32) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org iD8DBQFA9U22tvXNTca6JD8RAibYAKDHK+QwHHPXuwK8COGp1XhxRM1s7wCdFmIf yxc3AlFTMt9LWvRxYdXwMoM= =6oIc -END PGP SIGNATURE- - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

manager app: sessions
I have read the Manager App HOW-TO at http://jakarta.apache.org/tomcat/tomcat-4.0-doc/manager-howto.html So, I'm accessing the following URL just like the example shows: https://www.(mydomain).com/manager/sessions?path=/ristmain I'm trying to interpret these results: OK - Session information for application at context path /ristmain Default maximum session inactive interval 30 minutes 30 - 40 minutes:100 sessions 120 - 130 minutes:1071 sessions My main question is, does Tomcat update these numbers in realtime, or only once in a while (like every 10 minutes)? I'm wondering why it says 30 - 40 minutes...? I logged into the web app as another user and that 100 didn't increase. It's hard for me to tell if my logging in was counted later on just because real users are logging in and out all the time. I guess the most important thing I need to know here is how long I should wait to take another sampling...wait 10 minutes each time, or what? If it says 100 sessions, then that means within the past half an hour (or 40 minutes?), there have been a total of about 100 users logged in, right? Are these the only statistics available about sessions? Would I have to customize Tomcat to find out more?

image redirect
Hello. I am used to using Apache Httpd in front of Tomcat to create Redirects for images. This way, I can re-route all calls to *.jpg to my image server. But now I don't have Apache Httpd installed. Can I do the same with Tomcat? This is the setup in Httpd: VirtualHost www.mysite.com ServerAdmin [EMAIL PROTECTED] DocumentRoot /code/www/webapps/ ServerName production RedirectMatch /images/(.*)$ http://images.mysite.com/images/$1 JkMount /*.do tomcat JkMount /*.vm tomcat JkMount /*.jsp tomcat /VirtualHost So, with the RedirectMatch I can route all of my image calls to another server. Is there somewhere in the conf/server.xml where I can setup the same feature? Right now I have a servlet filter setup in my web.xml file for the application. But I was wondering if it could be done in Tomcat instead of in my application. If not, I guess I'll keep using my filter. Thanks a lot.

Re: manager app: sessions
Stephen, If I understand what your asking, you are looking at statistics generated by Tomcat that tells you how many *active* sessions are still laying around inside the server.

RE: NPE in ActionForm where it is not be possible
Yoav,
Wow, had not considered that. I'm going to sort of say this back to be
sure I understand though :)
So if we stop Tomcat then my session, with any stored attributes that
contain an ActionForm, will be serialized to persistent storage
(disk). Upon restart the sesson and its attributes are
deserialized(reconstituted so to speak). The CATCH is that for any
included ActionForms, standard object initialization does not occur -
either through static initializers or through the constructor. So I can
end up with a NPE when I reference the log instance variable.
OK, that definitely explains the problem. It is only after a restart
that this is occurring - consistently. So, how to fix this.
Ugh! I've got 127 classes that use this construct! The good news is that
the objects that are likely to be persisted to the session tend to be
either ActionForms or a limited number of domain objects - about 50 in
total. They mostly derive from common superclasses so I might get some
help by putting an inner class that wraps the Log type in the
superclass. But, I need access to the actual class name of the instance
so I can initialize the Log object with objectname.class.
Is there a more elegant way to do this? I know using AOP would offer
some much more elegant solutions, but do not think I'm ready to throw
this at a production system.
Any comments/ideas are welcome. And thanks again to Yoav for helping me
to see the light here.

Because Log is not Serializable, you can't put it in the session. So

Tomcat will save and restore your sessions across server restarts by
default. That includes session attributes that are Serializable. If
the Form was in the session, it will be deserialized: this is not the
same process as reconstruction. So if you choose to stick with this
transient modifier, you will need to check for the log being null

Re: manager app: sessions
What? I can only find out how many sessions have been active for 30 to 40 minutes and 120 to 130 minutes? That doesn't seem to make sense. I understand if Tomcat doesn't want to update the stats too frequently, but what about stats on sessions logged in more than 40 minutes and less than 2 hours? Why would it arbitrarily jump up to 2 hours? And how likely is it that I have only 100 users who have been active for a total of exactly 30 to 40 minutes, but 1071 users who have been active for over 2 hours? If my timeout is set to 30 minutes, then that means they have to keep browsing the site at least every 30 minutes to avoid getting timed out.

RE: NPE in ActionForm where it is not be possible
Hi,
I just wanted to confirm your understanding is correct. It's
unfortunate to discover this now, from your perspective, since you
already have many classes affected by this, but then again better late
than never ;)
I tend to agree about throwing AOP into a production system at this
point in time.
In production code I tend to use static loggers so this is not an issue
for me, and there are other workarounds of varying applicability, such
as checking for a null logger before using it (a tiny checkLogger method
in your superclass called by every method, or something like that: it's
slow and ugly, but it works and depending on other constraints you may
want this).

Callback mechanism for Real
I have integrate my web application with Active Directory and the JNDIRealm working fine. However I need to create a workflow that detects when the Active Directory user must change their password at next logon is set and force them through a workflow to do so. The problem I have is there doesn't seem to be a callback mechanism from within the REALM interface to extends/override the JNDIRealm and redirect the user to a different page to change their password. Does anyone have a callback mechanism to do such a thing? Or perphaps solved this problem in a different way?

Tomcat 5 fails on serialized objects
I have a class that implements Serializable. This class is put in a web app deployed under TC. when the webapp is accessed via a browser, an instance of this class is placed in the web session by the webapp. If an active session contains an instance of this class and if TC is restarted, when webapp tries to create an instance of this class, TC throws a ClassNotFoundException for this class. Everything works fine if the webapp cleans the session i.e. by calling session.invalidate(). What is happening here? Does TC persist the session? Using TC 5.0.25, Win XP.

Do servlets as welcome-files work in TC5?
I'm having trouble using a servlet as a welcome file in Tomcat 5. I haven't found any definitive documentation on how to do it (The Servlet 2.4 spec doesn't even seem to be clear), but I've tried the following (taken from: http://www.onjava.com/pub/a/onjava/2004/02/11/jspcookbook.html): |servlet servlet-nameMyServlet/servlet-name. servlet-classcom.jspservletcookbook.MyServlet/servlet-class /servlet !-- optionally map the 'MyServlet' servlet to a URL pattern -- servlet-mapping servlet-nameMyServlet/servlet-name url-pattern/myservlet/url-pattern /servlet-mapping !-- rest of web.xml ... --| |welcome-file-list welcome-fileMyServlet/welcome-file welcome-filedefault.jsp/welcome-file /welcome-file-list| The names were changed to match my particular needs, but the functionality should have been the same. I'm using the 2.4 xsd. The servlet I'm trying to map is a Struts ActionServlet, so the URL pattern is actually *.do, not /myservlet, but my understanding is that it shouldn't matter. With that all done, requests to http://mymachine/myWebapp/ should call MyServlet, but they don't. Either default.jsp is returned or a directory listing if default.jsp is missing. Does this work in TC5, and if so, how do I make it work? K.C. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

re-deploy a webapp with new .properties files
Hello again. I push myapp.war file to my staging server. Then I use the deploy function in the manager app. http://server/manager/deploy?war=jar:file:/wars/myapp/1.3/myapp.war!/update=true Most of the app gets reloaded, which is great. But some things do not. Like anything in the /WEB-INF/classes/ directory. Not sure yet about the /WEB-INF/lib/ directory. Am I doing something wrong? Is there a different command? After I deploy I tried reloading. Same result. Seems like the only way to get Tomcat to reload things like .properties files is to restart it. I know this can't be the case, so I'm hoping someone could point out to where I missed that in the documentation. Thanks again.

unfortunate to discover this now, from your perspective, since you

I tend to agree about throwing AOP into a production system at this
point in time.
In production code I tend to use static loggers so this is not an
issue
for me, and there are other workarounds of varying applicability, such
as checking for a null logger before using it (a tiny checkLogger
method
in your superclass called by every method, or something like that:
it's
slow and ugly, but it works and depending on other constraints you may
want this).

Subject: RE: NPE in ActionForm where it is not be possible
Yoav,
Wow, had not considered that. I'm going to sort of say this back to
be sure I understand though :)
So if we stop Tomcat then my session, with any stored attributes that
contain an ActionForm, will be serialized to persistent storage
(disk). Upon restart the sesson and its attributes are
deserialized(reconstituted so to speak). The CATCH is that for any
included ActionForms, standard object initialization does not
occur - either through static initializers or through the
constructor. So I can end up with a NPE when I reference the log
instance variable.
OK, that definitely explains the problem. It is only after a restart
that this is occurring - consistently. So, how to fix this.
Ugh! I've got 127 classes that use this construct! The good news is
that the objects that are likely to be persisted to the session tend
to be either ActionForms or a limited number of domain objects -
about 50 in total. They mostly derive from common superclasses so I
might get some help by putting an inner class that wraps the Log
type in the superclass. But, I need access to the actual class name
of the instance so I can initialize the Log object with
objectname.class.
Is there a more elegant way to do this? I know using AOP would offer
some much more elegant solutions, but do not think I'm ready to
throw this at a production system.
Any comments/ideas are welcome. And thanks again to Yoav for helping
me to see the light here.

Shapira, Yoav mailto:[EMAIL PROTECTED] wrote:
Hi,
Because Log is not Serializable, you can't put it in the session.
So making it transient is fine. I also saw your reasoning for
making it dynamic rather than static.
Tomcat will save and restore your sessions across server restarts by
default. That includes session attributes that are Serializable.
If the Form was in the session, it will be deserialized: this is
not the same process as reconstruction. So if you choose to stick
with this transient modifier, you will need to check for the log
being null before every time you use it.

I notice, you define/initialize the instance variable log at
its declaration point.
Humor me: what happens if you initialize log in the ctor?

I've had to look at higher priorities for a couple of days :)
Thanks for the idea. I changed as follows:
...
// private transient Log log =
LogFactory.getLog(ChartWizardForm.class);
private transient Log log; // Logging instance for this class
...
public ChartWizardForm() {
showInactive = false;
altClassMeasOrder = false;
...
outputFmt=;
scaleFactor=;
log = LogFactory.getLog(ChartWizardForm.class); // --
ADDEDINITIALIZATION HERE } ...
But, still get the NPE :(
I'm defininig the instance variable as transient because Tomcat
complains about saving sessions that contain a private instance
variable (non-transient) of type Log. I was trying to get my
sessions to persist across restarts. Does that
RE: Tomcat 5 fails on serialized objects
The error is inside the webapp. The error message is following: 20040714 01:43:46 ERROR - Exception Message [java.lang.NoClassDefFoundError at com.xxx.Manager.getUser(Manager.java:525) Line 525 in Manager.java has the following code: User user = new User(); The class User is a java bean that implements Serializable. Later in a servlet the user object is put under session as an attribute. If the session is still active and TC is restarted, I get the above exception. There are no problems if the session is cleaned in the webapp. Also, this started hapenning only after the User object was made to implement serializable. There are no problems if the User object doesn't implement Serializable. Does TC behave different for serialized objects? Thanks Keshav [EMAIL PROTECTED] 07/14/04 01:34PM Hi, TC persists the session, yes, but that doesn't explain a ClassNotFoundException. Is the CNFE in your own code? If so post the relevant chunk.

Re: Retrieveing Unicode stuff from MySQL 4.1.x ?
Yes, I can't agree with this more u need to do sdome testing, use JUnit if u can But I would prefer not only use String.equals, but actually print out the HEX value of the string u need to print out the HEX value in: Just before the JSP form start submit when the action start process the form just before any database process after that, goto Mysql console and print out the HEX value that u just insert of update and do the same when u retrieve that value from database in any case, all the above HEX values should be the same I know it is ignoring but many people go throught this, sometimes ago I have the exact problem like this when I use Mysql + PHP + SQL Server to do database sync.

Re: Running Tomcat as service on Win2000 Server
tomcat 5 has an installer option to install as a service, although it only sets it to auto instead of manual when you tick it. From the docs located at this page: http://jakarta.apache.org/tomcat/tomcat-5.0-doc/setup.html Introduction Windows Installing Tomcat on Windows can be done easily using the Windows installer. Its interface and functionality is similar to other wizard based installers, with only a few items of interest. Installation as a service: Tomcat will be installed as a Windows NT/2k/XP service no matter what setting is selected. Using the checkbox on the component page sets the service as auto startup, so that Tomcat is automatically startup when Windows starts. For optimal security, the service should be affected a separate user, with reduced permissions (see the Windows Services administration tool and its documentation). Java location: The installer will use the registry or the JAVA_HOME environment variable to determine the base path of the JDK or a JRE. If only a JRE (or an incorrect path) is specified, Tomcat will run but will be unable to compile JSP pages at runtime. Either all webapps will need to be precompiled (this can be easily done using the Tomcat deployer), or the lib\tools.jar file from a JDK installation must be copied to the common\lib path of the Tomcat installation. Tray icon: When Tomcat is run as a service, there will not be any tray icon present when Tomcat is running. Note that when choosing to run Tomcat at the end of installation, the tray icon will be used even if Tomcat was installed as a service. The installer will create shortcuts allowing starting and configuring Tomcat. It is important to note that Tomcat administration web application can only be used when Tomcat is started.

Re: Running Tomcat as service on Win2000 Server
1. Download Tomcat 2. Unzip the archive to a directory 3. Set CATALINA_HOME 4. Open a command prompt and type... %CATALINA_HOME%\bin\service.bat [install | remove] 5. Open the services applet from the admin tools 6. Start the Apache Tomcat service Note that I've had to add JAVA_HOME/lib/tools.jar to the classpath (inside service.bat) in order for JSP compilation to work properly, but servlets should run fine with the stock service.bat.

I need a pointer about persistent info for my servlet, please
We are deploying a servlet front end to an existing application. When the application is installed, the user picks some parameters, like the install directory, that aren't known to us when we make the .WAR file we deploy from. However, our servlet needs to know this, and it needs to know it in a way that survives redeployment of the servlet from the .WAR file - so I can't put it into the WEB-INF/web.xml file, as this will be overwritten when the servlet is redeployed in Tomcat. During product installation, where can I write the information the user chooses so that it will always be available to our servlet? (And in what form, please?) I've read about a tomcat/conf/Catalina/localhost/servletname.xml file, but I have only seen the examples for the built-in Tomcat apps, and those don't show examples of param...something for me to use. Can anyone point me to something that I can use for this? Thanks, Bret
