Log 4j error on tomcat shutdown
Hi All, During tomcat (version 6.0.18 with jdk 1.5) shutdown , I get the following error in the console : log4j:ERROR LogMananger.repositorySelector was null likely due to error in class reloading, using NOPLoggerRepository. Whats wrong here ? What does this mean and how do I resolve this ? PS: I am using lo4j1.2.15.jar in my webapp's WEB-INF/lib directory.

RE: Tomcat running out of threads.
Hello, According to tomcat documentation, JkOptions +DisableReuse has some performance penalty, because opens new connection for each request. In my case, issue was solved by setting the param: connectionTimeout on the ajp13 connector / entry on tomcat's server.xml Also look at docs for firstReadTimeout parameter. Now mod_jk is using a pool of connectors, but tomcat expires old threads on the pool so issue was solved. Regards, Bernardo.

It is a side effect of the default clean-up Tomcat does to attempt to avoid memory leaks caused by bugs in user applications and/or third party libraries. If you are sure you application doesn't have any memory leaks then use org.apache.catalina.loader.WebappClassLoader.ENABLE_CLEAR_REFERENCES=false See http://localhost:8080/docs/config/systemprops.html for more info.

From: Bernardo Cabezas [mailto:ber...@bergantells.net] Hello, According to tomcat documentation, JkOptions +DisableReuse has some performance penalty, because opens new connection for each request. There is actually quite a lot of disagreement between the Tomcat committers about the correctness of that statement in the docs. I am aware of fairly large deployments that actaully saw a significant performance increase by enabling that option. That said, it may well be that a similar performance increase could have been obtained by correctly tuning the timeout parameters. It is certainly the case the YMMV and you need to test in your environment.

RE: Logging configuration in Tomcat
Chuck There are many web apps. Log4j logger is used in all web apps there are no system.out or system.err If I configure log4j at each web app level using log4j.properties, am abile to achive log file rotation but, this requires one log file per web application. What I am interested is one log file for all web apps - say catalina,out this file should be rotated based on size, which should be configurable. Am not Ok with catalina.out being rotated once in a day or once in a month. Could you let me know, how to achieve my requirement, please ?

Comitting Valve-code to Tomcat
Dear all,
I've got a piece of code here which I think might be useful not only
for me but others.
Since I believe in sharing knowledge, I'd like to pass it to the ASF
so that it might become a part of Tomcat.
Problems whch are solved by this Valve:
--
As you may know, j_security_check works as follows:
- If a request to some protected content comes in, Tomcat stores this
request internally
- a html/jsp/servlet is called asking for the login-credentials
- the credentials are then passed to j_security_check which then
checks Authentication / Authorization (AA)
- if AA is ok, the old url, which was stored before, then is requested.
However, there are some scenarios where this flow does not work and we
would want to always redirect to a *pre-defined starting-page*.
There are some options like
- http://securityfilter.sourceforge.net
- implement your own JAA
- JSSO
- etc.
However, those solutions sometimes are missing something (like i.e.
SingleSignOn), or you have to dive into how to implement JAA, a new
framework etc.
Well, to circumvent all this and make live easier for some of us, I've
developed a Valve, which handles those problems:
After having declared said Valve in ${catalina.home}/conf/server.xml,
the only things that have to be done are:
- the protected area needs to be specified in server.xml
- the default starting-page needs to be specified in server.xml
- the default starting-page *must* be in the protected area
Now if a request to the protected content comes in without
authorization, the following things happen:
- the request will be redirected to the pre-defined starting-page
- since the pre-definied starting-page is within the protected area,
the login-html/jsp/servlet will be called to ask for the credentials
- j_security_check will check the credentials given and redirect to
the pre-definied starting-page (i.e. /protected/index.html)
Since I believe that this Valve might be useful to some of us, I would
like to share the code / docs with the ASF so that it might become
part of Tomcat.
Could somebody please let me know the steps required?
I've read http://tomcat.apache.org/getinvolved.html already, and I've
also read http://www.apache.org/foundation/how-it-works.html, however,
I'm not really sure of what to do next.
Shall I just put the code into the dev-mailinglist?
I'm aware that ASF might also decline this Valve becoming part of
Tomcat, however, I believe in sharing knowledge, therefore I'm trying
it anyway ;)
Looking forward to your suggestions!
Gregor

The main thread is stuck at at com.valleyoak.model.Payment.clinit(Payment.java:136) (at com.valleyoak.util.IVosTableInfo.findColumnTables(IVosTableInfo.java:161)) - last line the cluster thread is stuck at at java.lang.Class.forName0(Native Method) because the main thread is stuck during a clinit (this is class init, happens directly after class loading, to do static initializers), the cluster thread can't continue. what you need to investigate is why at com.valleyoak.util.IVosTableInfo.findColumnTables(IVosTableInfo.java:161)) - last line is stuck, but it does look like its a problem with your code.

Re: single instance of background job?
What I did was a little bit of extra work on top of quartz. I have a table that stores the configuration for all of my quartz jobs. When a quartz job kicks off, it will first try to update its last execute time in the table. If the last execute time is too new the update will fail and the process will exit. I use spring-javaconfig to build my quartz configuration from this table procedurally on application startup and I provide a web and Ice API for administrators to make changes. -Matt Rusty Wright wrote: This isn't really a Tomcat question I'm guessing but I don't know where else to ask. In our setup we have multiple Tomcats behind a load balancer. I have a background task that will run once a day, via Quartz. All Tomcats will be using the same war so they will all run the job, but I need it so only one of them runs the job. I'm looking for ideas for how to implement this. At the moment all I can think of is to use a table in a database with a unique constraint on a column, and each background process tries to insert today's date (-mm-dd) and the one that succeeds runs the job, and the ones that don't, do nothing.

Tomcat returns HTTP status of 200 when HttpServletResponse.sendError() called.
Greetings,
In tomcat 6.x (6.0.14 in my case) I am seeing the following behavior:
If I designate default error pages in my web.xml file:
error-page
error-code404/error-code
location/docs/error404.html/location
/error-page
Then when I call HttpServletResponse.sendError():
public class DispatchServlet extends HttpServlet {
public void doGet(HttpServletRequest request,
HttpServletResponse response) {
response.sendError(404);
}
}
Tomcat returns the designated page, but with an HTTP status of 200.
If I drop the default page then I get the canned response with an HTTP
status of 404.
Is that correct?
Seems like it shouldn't work that way to me, but then that's why I'm
here, looking for some insight.

some config issue with Apple supplied Tomcat
Hi, I am trying to setup a cluster using Apple supplied Apache2 and Tomcat. On OSX, tomcat is in /Library/Tomcat. Apache is configured in a mixed way, because Apple installs 1.3 and 2.2, so there is /etc/httpd for config of 1.3 and /etc/apache2 for config of 2.2. However even the config file in /etc/apache2 refers to the workers.properties in /etc/httpd :) Looks like as siamese twins in the process of separation. Tomcat version 6.0.18 Java: java version 1.5.0_16 Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_16- b06-284) Java HotSpot(TM) Server VM (build 1.5.0_16-133, mixed mode) apache2: version 2.2 Tomcat is running after checking the checkbox and restarting Apache2 pathsrv1:httpd administrator$ ps -avx |grep tomcat 59195 Ss 0:01.10 0 0 0 600172628 -0 0.0 0.0 /bin/sh /Library/Tomcat/bin/tomcat-launchd.sh 62573 R+ 0:00.00 0 0 0 590472 92 -0 0.0 0.0 grep tomcat and I can get to the SessionExample via port 80. However I get this into the mod_jk.log: [Mon Jan 12 14:57:31 2009] [59281:] [error] init_jk::mod_jk.c (2701): Initializing shm:/usr/logs/jk-runtime-status.59281 errno=2. Load balancing workers will not function properly. Looking on the Internet someone recommended to create a run directory, that used to be in /usr/local/apache2/. I do not know if that is the solution for this Apple supplied config on OSx 10.5.6. I also have a second issue, but that might relate to this message above. I created a reverse proxy setup and this is what Apple put into the site configuration file: IfModule mod_proxy_balancer.c ProxyPass /apps/ balancer://balancer-group/ stickysession=JSESSIONID ProxyPassReverse /apps/ balancer://balancer-group/ Proxy balancer://balancer-group BalancerMember http://pathsrv1.yalepath.org loadfactor=1 /Proxy /IfModule Right now I have just one machine and I am trying it as a Balance member and also as a reverse proxy. So based upon the config, I thought that if I want to go to; http://pathsrv1.yalepath.org/apps/examples/servlets/servlet/SessionExample than the reverse proxy that is pathsrv1 will pass it to the balance member, that is again pathsrv1 and from there It will give me the SessionExample as if I would have gone just to http://pathsrv1.yalepath.org/examples/servlets/servlet/SessionExample Either my config is not right, or my thinking :) Any good hint is appreciated.

Tomcat: client disconnects?
Hi, We have a RHEL5.2 Linux server running Apache/2.2.3, Tomcat-5.5.26 MySQL 5.0.45. We are experiencing users having issues connecting to our RH server and getting disconnected with errors in their browsers that state there is a DNS error or page cannot be displayed. Users connect to Apache then Tomcat serves up our JSP's that sometimes accesses specific MySQL server DB's. We also have Mediawiki running - using PHP and Apache - that has disconnected users as well. Most of the pages seems to be index.jsp or index.php lately for both websites(These are websites internal - our company web servers). I have tried to view the Apache, Tomcat and Mysql logs extensively. In Apache: I only see a few 401 404's sometimes but with no further details. In Tomcat: it is a mess of exceptions that our developers try and keep cleaned up. ( We do not use Log4j) In Mysql: there are lots of slow queries I've been logging - 1 sec. The errors that occur are random browser disconnects - urls that end or start with *.jsp/ or *.php/ pages. We have also tried using WinXP host files and using an IP address to bypass DNS altogether - no luck. Examples below: # At 2:58PM - Jan 09, 2009: Page cannot be displayed IE6 using IP address. http://10.97.24.23/Qoe/custord1.jsp?id=6271pageMode=view While just reviewing an order (not editing) Hit refresh and it cleared up... Problem around 4:15PM - Jan 9, 2009: http://10.97.24.23/Sales/IndentedATPServlet?partNum=086EXUCCCXMAqty=1warehouse=M Problem around 5:05PM - Jan 9, 2009: http://wsi/Qoe/index.jsp (same thingPage Cannot Be Displayed) ### Our MysqL server has a tendancy to ramp up or the load avg increases using massive CPU cycles - I restart Tomcat and the system usually calms down - Mysql included. We are currently using tcpdump on the server Wireshark on the affected clients to look at the packet level of my connections to the webserver. I know more details are probably needed - this is a complex problem. And only seems to happen in the am right when users login to their machines and start up their browsers and then happens at the end of the day as well. I've tried looking at the timeframes in the message and other logs but can't find any relevant info that makes sense yet. We've debugged our MS Active Dir DNS here and used host files on the clients to stripping the Linux box of many un-needed services including IPv6. We haven't had other issues with DNS that I've noticed with other applications and/or servers in our entire organization. Any responses or suggestions are appreciated!

Tomcat POST Section Execution Size limit
Hello,
I am in the process of developing a small site using JSTL and Tomcat 6.0. I
already have a large portion of the site developed.
The construct of my standard JSTL .jsp page uses the standard Post-Redirect-Get
format and looks similar to:...c:if
test=${pageContext.request.method=='GET'} ... Generate HTML for GET Request
.../c:ifc:if test=${pageContext.request.method=='POST'} ... Execute POST
actions .../c:if...
I have noticed that I am running into some type of limit with the POST section
upon execution. When the POST logic being executed(includes SQL actions, CHOOSE
logic, etc...) reaches a certain size, I get the following error
java.lang.IllegalStateExceptionIf I trim any part of the POST Section
actions, it works without issuing error.
I went through many of the config options (such as maxPostSize) outlined at
http://tomcat.apache.org/tomcat-6.0-doc/config/http.htmland none of the changes
seem to make a difference. None of the individual JSP files so far exceed about
55KB
Does anyone have any insight into what would fix this issue ?
Thanks,BT

- Chuck
Well at first I didn't think so, but now I am wondering
After adding some more instrumentation I have determined that I am
inadvertently setting the status to 200.
I was replicating the problem with this servlet:
package opendap.experiments;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpServletRequest;
public class SendErrorTest extends HttpServlet {
public void doGet(HttpServletRequest request,
HttpServletResponse response) {
try {
System.out.println(Calling
HttpServletResponse.sendError(404));
response.sendError(HttpServletResponse.SC_NOT_FOUND);
System.out.println(HttpServletResponse.sendError(404)
returned.);
}
catch (Exception e) {
System.out.println(e.getMessage());
}
}
}
And a simple document service servlet:
servlet-mapping
servlet-namedocs/servlet-name
url-pattern/docs/*/url-pattern
/servlet-mapping
With this error-page:
error-page
error-code404/error-code
location/docs/error404.html/location
/error-page
I added some instrumentation and looked at the logs and saw that when
the sendError() method is called in the SendErrorTest servlet the call
returns immediately. And is followed by a the docs servlet receiving a
request for the error document, which since it is successfully
returning a document sets the HTTP status to 200.
Is sendError() using a redirect?
Is there a way to set the value of the location element in the error-
page declaration so that tomcat just grabs the file from the context
directory?
The java servlet spec (2.4) says:
If the sendError method is called on the response, the container
consults the
list of error page declarations for the Web application that use the
status-code
syntax and attempts a match. If there is a match, the container
returns the resource
as indicated by the location entry.
So what does the container returns the resource as indicated by the
location entry mean for tomcat?
Is there an example of a design pattern you can point me to?
Thanks,
Nathan

Permission problems for Downloaded files
Hi, I installed Apache 2.2 + Tomcat 5 + SSL on Linux and they run perfect. The Java web application gives users(after they login) ability to upload files(pdf,ppt..) then creates a record for them, right way users can see their records and can open the documents that they uploaded. The problem is when they click on the link to open the files that they uploaded before they get a forbidden screen. The Java program save upload files on the APache/htdocs directory. To solve that I have to run following command for the htdocs directory. chmod 755 the_name_document. After that the users can access their files. The uploaded files could be accessible right away. How can I solve this problem? Thanks, MK

Well at first I didn't think so, but now I am wondering
After adding some more instrumentation I have determined that I am
inadvertently setting the status to 200.
I was replicating the problem with this servlet:
package opendap.experiments;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpServletRequest;
public class SendErrorTest extends HttpServlet {
public void doGet(HttpServletRequest request,
HttpServletResponse response) {
try {
System.out.println(Calling HttpServletResponse.sendError(404));
response.sendError(HttpServletResponse.SC_NOT_FOUND);
System.out.println(HttpServletResponse.sendError(404)
returned.);
}
catch (Exception e) {
System.out.println(e.getMessage());
}
}
}
And a simple document service servlet:
servlet-mapping
servlet-namedocs/servlet-name
url-pattern/docs/*/url-pattern
/servlet-mapping
With this error-page:
error-page
error-code404/error-code
location/docs/error404.html/location
/error-page
I added some instrumentation and looked at the logs and saw that when the
sendError() method is called in the SendErrorTest servlet the call returns
immediately. And is followed by a the docs servlet receiving a request for
the error document, which since it is successfully returning a document sets
the HTTP status to 200.
Is sendError() using a redirect?
Is there a way to set the value of the location element in the error-page
declaration so that tomcat just grabs the file from the context directory?
The java servlet spec (2.4) says:
If the sendError method is called on the response, the container consults
the
list of error page declarations for the Web application that use the
status-code
syntax and attempts a match. If there is a match, the container returns the
resource
as indicated by the location entry.
So what does the container returns the resource as indicated by the
location entry mean for tomcat?
Is there an example of a design pattern you can point me to?
Thanks,
Nathan
It sounds like error404.html isn't a plain HTML file, but a page
that's generated by a servlet. Is that right? If so, the servlet
should not set the status to 200 for an error page - it should leave
the error status alone. Maybe you need a different version of the
servlet to handle error pages, or maybe your error pages should just
be static HTML files.

Re: single instance of background job?
Quartz has a clustering facility that makes this easy, the OpenSymphony website has more docs on this, investigate the forums/community there. org.quartz.jobStore.isClustered = true Using a JDBC JobStore with the cluster config should ensure that the job only runs once within the cluster. p Rusty Wright wrote: Hmm, I see your point.

Haven't checked the code yet, but I believe it treats it like a GET for the resource, so it's subject to whatever servlet mapping you have in place. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

How to have multiple loggers with shared code also using the logger?
How to have multiple loggers with shared code also using the logger?
In ${catalina.home}/lib there is a jar file that contains class MyLog. There
is a function in it
public class MyLog
{
public static Logger getLogger()
{
ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
URL log4j_properties = classLoader.getResource(log4j.properties);
String loggerName = log4j_properties != null ?
log4j_properties.toString() : default;
synchronized (MyLog.class)
{
Logger logger =
Logger.getRootLogger().getLoggerRepository().exists(loggerName);
if (logger == null)
{
logger = Logger.getLogger(loggerName);
System.out.println(Created logger: loggerName= + loggerName);
}
return logger;
}
}
}
The jar file in ${catalina.home}/lib contains common code used by all web
applications, and it calls MyLog.getLogger() to write some logs.
My ROOT application in ${catalina.home}/webapps/ROOT and web service
application in ${catalina.home}/webapps/mywebservice also call MyLog.
The intent of getLogger() above is to return the logger for the application
currently being run. I have verified that
Thread.currentThread().getContextClassLoader().hashCode() has value1 for the
ROOT application and value2 for the mywebservice application.
We have the following two log4j.properties:
${catalina.home}/webapps/ROOT/WEB-INF/lib/root.jar!/log4j.properties
${catalina.home}/webapps/mywebservice/WEB-INF/lib/root.jar!/log4j.properties
The value of loggerName is the first one when we're running the ROOT
application, and the second one when running the mywebservice application. So
far, so good.
After starting Tomcat, if we run the ROOT application first, then it will call
MyLog.getLogger(), and the log4j.properties found by the call to
Logger.getLogger() will be the first one above. If we run mywebservice first,
then Logger.getLogger() will find the second log4j.properties file. Any
subsequent call to Logger.getLogger() will use the same log4j.properties. So
suppose we run the ROOT application first, then the new logger will be
initialized with the first log4j.properties above. And then if mywebservice
calls MyLog.getLogger(), a new logger will get created, but it will be based on
the same log4j.properties file. You can see this because all applications log
to the same file (each of my log4j.properties specifies a different file).

Configuring Tomcat -- moving to another directory
Hello, I want to move Tomcat to another directory. Red5 server requires that I move Tomcat to a directory that has a path with no spaces in it.So, I moved the java sdk and I moved the tomcat server to the same directory. The directories are: C:\jbin\jdk1.6.0_07 C:\jbin\Tomcat6.0 Where is the configuration information for tomcat? I looked and could not find a file. I did notice that the Apache Tomcat Properties application (tomcat6w.exe) has paths in it, but I couldn't see where it was getting the information, and I couldn't change the path to the executable. Does anyone know how to do this?

You normally would put static error pages in a separate directory, so that they will not be processed by any of your servlets. I see the conflict in my design now: I mapped one of my servlets to be the default servlet: servlet-mapping servlet-namehyrax/servlet-name url-pattern*/url-pattern /servlet-mapping And since it doesn't serve static content like the Tomcat DefaultServlet, I'm not seeing the expected behavior for the error- page mappings. Which is kind of a bummer: People pretty much rely on the fact that the service defaults to the hyrax servlet. Is sendError() using a redirect? No, more like an internal forward. I just did some more testing and discovered that if I don't actually call response.setStatus() in my docs servlet (which serves the static content) then it seems to inherit(?) a status from the internal forward . Is that right? Would I be better off just not calling response.setStatus() unless something actually goes awry with the request? = = = Nathan Potterndp at opendap.org OPeNDAP, Inc.541.752.1852 - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
Reusing form configured in form based authentication
Hi, I have an application using form based authentication. Is it possible to use the same form as a stand-alone login screen? Default, if you enter the url of the form manually (or get it from your browser's history) and you submit it, you get an error message. You always have a smart-ass who will do this, so I want to have my application properly handle it and never want error screen to show. I would venture a guess that you just have to configure a proper servlet mapping for the j_security_check action to enable you to use the form directly also, but would that then cause problems for the server authentication? Or would Tomcat be able to handle this? And the j_security_check action would then probably have to be configured so that no authentication is needed for it to execute, right? Otherwise I'll land in a loop. Thanks! Charl - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
