CVE-2010-1157: Apache Tomcat information disclosure vulnerability

Severity: Low

Vendor: The Apache Software Foundation

Versions Affected:
- - Tomcat 6.0.0 to 6.0.26
- - Tomcat 5.5.0 to 5.5.29
Note: The unsupported Tomcat 3.x, 4.x and 5.0.x versions may also be
affected.

Description:
The "WWW-Authenticate" header for BASIC and DIGEST authentication
includes a realm name. If a  element is specified for the
application in web.xml it will be used. However, a  is not
specified then Tomcat will generate one using the code snippet:
request.getServerName() + ":" + request.getServerPort()
In some circumstances this can expose the local hostname or IP address
of the machine running Tomcat.

Example:
GET /application/j_security_check HTTP/1.0


HTTP/1.1 401 Unauthorized
Server: Apache-Coyote/1.1
WWW-Authenticate: Basic realm="tomcat01:8080"
Content-Type: text/html;charset=utf-8
Content-Length: 954
Date: Thu, 31 Dec 2009 12:18:11 GMT
Connection: close

Mitigation:
Administrators of web applications that use BASIC or DIGEST
authentication are recommended to set an appropriate realm name in the
web application's web.xml file.
Alternatively, the following patches may be used to change the default
realm to "Authentication required" (without the quotes):
- - Tomcat 6.0.x: http://svn.apache.org/viewvc?view=rev&rev=936540
- - Tomcat 5.5.x: http://svn.apache.org/viewvc?view=rev&rev=936541
These patches will be included in the next releases of Tomcat 5.5.x and
Tomcat 6.0.x. No release date has been set for the next Tomcat 5.5.x and
Tomcat 6.0.x releases.

Re: a servlet-related Java question


Mark, Chris and Kris, thanks.
You have all impressed the hell out of me.
You have also lost me.. at a guess about 50 lines ago.
But I get the idea, and it is nice to learn that such things exist.
I also believe this may be helpful to someone else some day looking for 
a solution to a case much more complicated than mine.
As for me, I think I will use the little grey cells and some additional 
circumstancial knowledge to try to figure out what the supplier /may/ 
have logically changed to that servlet, to restrict the number of 
methods to implement and log in my filter, to a reasonable "try first" 
list.  If that fails, I'll have a go at your proxy method, which looks 
really cool.
(Kind of reminds me of the Perl AUTOLOAD method, which does basically 
the same thing.)

I know from experience that Apache httpd does report the compressed size.

Well, the first step is to get agreement that it's a problem :). After that's 
done, look to see how difficult it is to fix.

I know the best way to get a problem fixed is to fix it yourself and submit the 
patch. A patch that I did made it into 5.5.29. When I get a chance, I want to 
try making startup multi-threaded. I'm running over 300 hosts per server and 
startup times are getting big. When I'm trying to do that I'll look at the 
logging. Maybe it will be easy...

Not to potentially muddy the waters, but I think your
InvocationHandler is invoking the method on the wrong object - it
shouldn't invoke it on the proxy but on the original request. So,
something like this:

public void doFilter(final ServletRequest request, ServletResponse
response, FilterChain chain) throws IOException, ServletException {

InvocationHandler handler = new InvocationHandler() {
public Object invoke(Object proxy, Method method, Object[]
args) throws Throwable {
// log some stuff
return method.invoke(request, args);
}
};

HttpServletRequest proxyRequest =
(HttpServletRequest)Proxy.newProxyInstance(HttpServletRequest.class.getClassLoader(),
new Class[] { HttpServletRequest.class }, handler);

chain.doFilter(proxyRequest, response);
}

I agree with Pid: update the webapp, but don't restart Tomcat.
Restarting Tomcat might be difficult if the updating software is
actually running within Tomcat.

Tomcat will not help you at all, except for some of the utilities it may
provide to help you re-deploy a webapp (such as the deployer ant task,
or the manager app itself).

First, I would provide two apps to your customers: the first is the
actual webapp itself, and then provide a second app to check for
updates. There's no requirement that the updater be a webapp, nor that
it even be written in Java.

One of the first questions you need to ask yourself is what is involved
in an update? Typically, code updates can be done either with patches
(or, at least, new copies of only the files that have changed) or with a
completely new WAR file. Which do you prefer? The former will likely
result in quicker update times, but will be more difficult to implement.

What about data storage changes? Does your webapp know how to startup
and make whatever changes are necessary in order to ensure a sane
environment for itself? Many PHP-based webapps are like this (Bugzilla,
Wordpress, etc.) but I've never seen a Java webapp do it. Maybe I just
don't deal with too many webapps that I haven't written myself :) If
your webapp isn't this smart, you'll either have to make it smart, or
implement this data storage upgrade as part of your "updater" app.

Next, you have to think about how automated this should be: is it okay
to bounce a customer's Tomcat in the middle of the day? You might want
to have some options for scheduling these update checks and scheduling
the actual updates themselves.

Finally, once you've figured out how to update your data and your code,
it's trivial to build a new WAR file (or exploded WAR directory
structure) and have Tomcat redeploy it: you'll need to have the
"manager" app installed. The manager can be used to deploy, undeploy, or
redeploy any webapp using simple HTTP GET requests.

See the documentation for the manager app on the TC site for more
information.

I would consider this to be a bug, though Tomcat may be mimicking Apache
httpd behavior.

On the other hand, the AccessLogValve is probably executed without any
knowledge of the compression in use, and might not be able to actually
detect it without a lot of work. While this might technically be a bug,
it may not be something anyone is willing to fix.

It's pretty inaccessible for novice Java programmers, but you could use
the "proxy" API which is jsut about the coolest thing available in Java IMO.

This is how you do the wrapping of the request:

import java.lang.reflect.Proxy;
import java.lang.reflect.InvocationHandler;

public class RequestMethodCallLogger
  implements InvocationHandler, Filter
{
  public void doFilter(...) {
HttpServletRequest wrappedRequest
 = Proxy.newProxyInstance(HttpServletRequest.class.getClassLoader(),
  new Class[] { HttpServletRequest.class },
  this);

chain.doFilter(wrappedRequest, response);
  }

  public Object invoke(Object proxy, Method method, Object[] args)
  {
// Log to your favorite logger here

return method.invoke(proxy, args);
  }
}

Basically, the Proxy class allows you to intercept the calls to
interface methods. The implementation of the "invoke" method is just a
pass-through to the "real" method after logging (an exercise left for
the reader).

This can be optimized a bit if you need to use it long-term, but the
above is about as compact as it gets.

I'd still recommend the use of jad, honestly.

How about providing another parameter which indicates the original
value, and the adjustment is relative to that? Refresh wouldn't
interfere with that.

Or, better yet, put the actual value you want in the URL instead of an
adjustment.

Yep.

You could play games with reflection but with IDE code generation just
writing the methods will be quicker.

Your question is so unclear that it is not even evident if it is 
off-topic. Can you rephrase that ?


I guess that by "refresh(f5)" you mean that the user, in his browser, 
requests a refresh of the page, and that this causes a new request to 
the server ? If so, then what, on the server, does what to what calendar ?

Jad can get your the (roughly) original Java source code for the whole
class. You have to figure out what the variable names really should be
(because they are lost during the compilation process and are replaced
by things like String s1, s2, s3, etc.) but you can get a general idea
of what the servlet is doing.

If you just want to see a list of method calls from a particular method,
you can use the standard Java tool "javap" with the "-c" switch which
will disassemble the class (per method, which is nice) and you can just
read the methods that get called.

Presumably, you already know the stack trace of where the error is
thrown, though.

This may or may not work the way you expect it to work. I would

Because you have mostly likely configured it to be invoked when a GET
request is processed. Tomcat doesn't have any idea what your filter
does: it just calls it whenever appropriate (where the definition of
"appropriate" is based upon your configuration in web.xml).

It will be called for all HTTP methods unless you configure it to be
called otherwise.

That's a good start, but it won't solve all your HTTP GET problems
because you simply cannot control what the client does with the
parameter encoding. It's always better to use HTTP POST when sending
non-US-ASCII-encoded text.

You'll have to either ask your ISP what URIEncoding they use (and hope
they use UTF-8) or use HTTP POST instead of HTTP GET.

Sniffing the wire would be a good thing to do: you'll see what the
encoding looks like on the way from the client to the server.

Okay. Have you confirmed that the server is getting the encoded URL the
way you think it should be encoded?

Yes, on a web page, POST requires using a . What's wrong with
that? I'm not sure I understand what you mean when you say you don't
know in advance what the keys of the request will be.

If you are using javascript to send the data to the server, I would
think that switching from GET to POST would be trivial.

Because you have mostly likely configured it to be invoked when a GET
request is processed. Tomcat doesn't have any idea what your filter
does: it just calls it whenever appropriate (where the definition of
"appropriate" is based upon your configuration in web.xml).

It will be called for all HTTP methods unless you configure it to be
called otherwise.

That's a good start, but it won't solve all your HTTP GET problems
because you simply cannot control what the client does with the
parameter encoding. It's always better to use HTTP POST when sending
non-US-ASCII-encoded text.

You'll have to either ask your ISP what URIEncoding they use (and hope
they use UTF-8) or use HTTP POST instead of HTTP GET.

Re: UTF-8 encoding in Tomcat 6.0

Mircea LUTIC wrote:

Hello Chris,

I will save Chris one answer :

1. If the filter does not influence the decoding of the GET parameters why is it called on GET requests?

Because the filter may want to, for example, modify or add request
headers to the request (or response headers). Or it may want to change..
the parameters, or rather the request's "query string" as a whole (the
part of the URL after the "?").

I think what Chris meant, is that the filter does not influence the way
in which a call like getParameters() works. The standard
getParameters() method takes the request URI (as it sees it by the time
it runs) and parses its query_string part into a table of parameter
names and values, according to fixed rules which you cannot change.

What your filter /could/ do, is to create a "request wrapper object"
containing the original request. This request wrapper would for example
pass an already-modifed request URI to the getParameters() method.
Or it could re-define the getParmeters() method, to return modified
parameter values.

When an application then runs and calls getParameters(), it will get the
result of the getParameters() of your wrapper object, instead of the
getParameters() of the original object.
For example, the result would be already-"translated" parameter
names/values.

(You have to do it this way, because the original HttpServletRequest
object is immutable, it cannot be modified directly.)

2. How about http : PUT, HEAD, etc?

Same thing.
And same thing for the request body, if any.

There are some additional nuances and details to what I wrote above, but
I hope that this already helps somewhat.

a servlet-related Java question


Hi.
A while ago, I wrote a servlet filter which has served me well since, to 
wrap a servlet for which I do not have nor can obtain the source code, 
and of which I only generally know what it does.
Now it seems that with a new version of this servlet, the servlet itself 
crashes when wrapped by my filter, with a 
java.lang.StringIndexOutOfBoundsException.


My servlet filter, under certain conditions, creates a 
HttpRequestWrapper derived object, which it passes to the servlet 
instead of the original HttpServletRequest object.
I have a suspicion that the ultimate reason for the servlet crash, is 
that it now calls a method which I have not re-defined in my wrapper, 
which method the previous servlet version did not call (and that it is 
not very defensive about the result it expects to get, but nothing I can 
do about that).


All this to ask the following : is there some generic java tool which 
allows to examine a compiled .class file, and determine which methods of 
HttpServletRequest it calls ?

I do not need nor want to decompile the class, just to know what it calls.

Thanks.

The filter cannot influence the way that GET parameters are decoded. The
only way to change that is to set URIEncoding="UTF-8" on your
 in server.xml.

Your best bet is to transfer all non-US-ASCII data in request /bodies/
by using HTTP POST.

If HTTP POST is not acceptable, please let us know why and perhaps we
can suggest some alternatives.

What does the Utf8encode function do? What does the escape function do?

The + in that listing is saying that server.xml.orig has some extra
permissions that server.xml hasn't.

Windows permissions are not the same as Cygwin permissions.  Use Windows
tools to inspect the permissions on both files, and use Windows tools to fix
the permissions on server.xml.  Also, get used to using Windows tools to

Hi Andre,

I did as suggested. Tomcat is running fine as service Tomcat1.

I have set CATALINA_HOME=C:\tomcat1 and CATALINA_BASE=C:\tomcat1
(I set the env var from Control Panel -> System Properties ->Advanced ->

What is the next step for additional instance on different port?

IIS ->Tomcat Configuration Question

2010-04-21 Thread Frank Zappa

Hello,

Our group is using IIS as a gateway server to Tomcat. 
(Unfortunately Apache can't be used for this project) 

Our system uses smart cards, so a pki certificate is passed from the browser to 
the gateway server. Does anyone know how to configure IIS to pass the 
user's certificate through IIS to Tomcat?

Thank you kindly!

Re: mod_jk reply_timeout and error state

2010-04-21 Thread Sean GAO

Hi Rainer,

Thanks for your informative and thoughtful reply.

Yes, we are definitely going with CMS. It's a product environment so
we have to be careful with whatever we plan to do. By tweaking
reply_timeout, be it hard or soft, we were actually circumventing the
problem rather than facing it. Which is lame, I know. Anyway, thank
you again for the help and insight.

Regards,
Sean

Could not get dir listing

2010-04-21 Thread Christoph Kukulies

Strange. Don't know whether this has happened since I upgraded to Tomcat 
6.0.26, anyway, my application doesn't start anymore.


It's a ROOT app, which replaces the stuff, that is normally put into 
ROOT by the tomcat distribution.

Tomcat isn't likely to recover from a situation where the webapps
directory disappears.

Any reason why not?

Yes.  There won't be a recovery issue, because the app won't fail when
the share disappears.

If you move the content directory to the top-level, it will become an
application in it's own right.  e.g.

  webapps\content

It will still appear in the URL space as /content

Re: How to run second instance of Tomcat 6.0.20 on separate port


Kapil Godara wrote:

Hi

I copied the entire folder Tomcat 6.0 at C:\Program Files\Apache Software
Foundation (where tomcat is installed) to Tomcat_instance2 .

...

Let's start again, from the beginning.

This has been discussed many times on this forum, but I believe it is 
worth repeating it, because it is probably the source of the confusion.


In the Tomcat website download page, there are several versions :

- one is for Unix/Linux. That is a "complete" version, with all the 
files packed together in one .tar.gz file.  To install it, you unpack 
these files under one new directory for Tomcat, and it creates a set of 
subdirectories conf, bin, etc..


But for Windows, there are *two* versions :
- one is a "simple" version, named "installer", which is destined for 
the quick and simple installation of a single Tomcat under Windows, to 
run as a Windows Service. This is apparently the one you downloaded and 
installed. This version does not contain /all/ the same files as the one 
for Unix/Linux above, only a subset of them.


- the other one is a "zip" version, which does contain all the same 
files as the Unix/Linux version, and even some additional ones.
This version /also/ allows you to install Tomcat as a Windows Service, 
but this requires a bit more work.  It also provides all the files 
necessary to install a second instance of Tomcat and run it as a second 
Windows Service.

This is the one you should download now.

My recommendation is :
- remove the first version of Tomcat that you downloaded and installed 
(the .exe version).

- download the zip version
- decide on a "main" and "second" directories where you will run your 
two instances of Tomcat.
I suggest that you pick directory paths that are simple, without spaces 
in the name.  Like "c:\tomcat1" and "c:\tomcat2".  That will save you 
time and problems later.

- unzip the downloaded Tomcat zip version in the first directory.
Note for the future that this is now your "CATALINA_HOME" directory.
- in the directory c:\tomcat1\bin, run the "service.bat" script, to 
install this Tomcat instance as the first Windows Service.  Give it the 
name "Tomcat1".

For this Tomcat, the "CATALINA_BASE" is also "c:\tomcat1".

When all the above is done and you have a running first Tomcat instance, 
then come back here for additional information on how to run an 
additional instance, using the same CATALINA_HOME, but a separate 
CATALINA_BASE.

Re: seperating content from the application

2010-04-21 Thread Electronjockey

Since Windows 2003 doesn't support symlinks to network shares, you might 
be able to use DFS. Though someone who knows DFS better than I might 
know for certain.


Something like this where "L:" is your local drive:

L:\path\to\local\webapps\Root\applicationfiles
L:\path\to\local\webapps\Root\publications  
-> \\DFS\network\target\publications
L:\path\to\local\webapps\Root\images

the application comes as a war file and the content is placed via another

the folder structure is placed on a windows share.


Our current problem:

Whenever there is a problem with the share, the application crashes,

When the share comes back online, tomcat does not recover from the failure

Now I have the following questions:

I think separating the application from the content and placing the

I know placing everything local to the tomcat will be the best way and

To get this running, I suggest you:
1) Download the .zip version of 6.0.20;
2) Unzip it somewhere safe;
3) Copy the missing .bat files to your second installation;
4) Carry on with what you were doing now that you have the files.

If you later want to install the second instance as a second service, you
can do that - but I'd get it running standalone first.  It's far easier to
debug startup errors on a standalone Tomcat, in my experience.

Re: How to run second instance of Tomcat 6.0.20 on separate port

Hi

I copied the entire folder Tomcat 6.0 at C:\Program Files\Apache Software
Foundation (where tomcat is installed) to Tomcat_instance2 .
(I installed tomcat 6.0.20 using apache-tomcat-6.0.20.exe, it does not
create any startup.bat or shutdown.bat file in bin folder. this installation
creates window service. tomcat6w.exe in turn calls tomcat6.exe)

I have set two environment variables as

CATALINA_HOME=C:\Program Files\Apache Software Foundation\Tomcat 6.0  and
CATALINA_BASE= C:\Program Files\Apache Software Foundation\Tomcat_instance2

Am I missing something? I did read RUNNING.txt it says in bin I should have
setenv.bat. Do i need to create this? What should be written in this bat
file?

I think you didn't copy the entire installation.

You can run two Tomcat instances from the same installed binary by
setting separate CATALINA_BASE and CATALINA_HOME environment variables.

Re: UTF-8 encoding in Tomcat 6.0

Also, my application will eventually be put on a web- based hosting provider 
and I may not have access to the server.xml file. What I want is my application 
to be fully UTF-8 based regardless of what the server is configured like.
The request javax.servlet.Filter system which is configured in the web.xml file 
seems to be the way to do it.

Thank you,

The filter does get called on my GET request.
In my understanding, a filter is the reccomended method of handling UTF-8 for 
both GET & POST (as well as other methods like HEAD, PUT etc.).

When the request is "test.jsp?Name=larevolu%C8%9Bie" as in the example page
the EncodingFilter.doFilter function is being called and it calls 
the EncodingFilter.check function as below

Name=request.getParameter("Name");
if (Name!=null)
check(Name, lang);

and the String Name is incorrect as mentionned in the comment below:


void check(String Name, java.util.Locale lang)
{
int c8=Name.codePointAt(8);//c8=200=C8 // should be 539=21Bh = ț
int c9=Name.codePointAt(9);//c9=155=9B // should be 105= 69h = i
char ch[]={Name.charAt(8),Name.charAt(9)};
int x=c8+c9;//to have eclipse (Galileo) display the above
String s=new String(ch); 
}


server.xml contains the following:

Hi Mircea,



That filter you wrote is for POST and it has nothing to do with GET request.



Have you check the documentation on the conf/server.xml on the following line?

I created an encoding filter with no luck.

Re: gc new capacity of JVM is gradually reducing when webapp(tomcat) started

2010-04-21 Thread Peter Crowther

This says that the JVM is tuning its memory boundaries to best suit your
application.

Do you have any evidence that this is bad for your application?  Or are you
simply trying to find out why it is happening?

to install the Poilcy agent I need to create a separate instance of tomcat
on different port say 8081.

My procedure:

Step 1 - Installed tomcat 6.0.20 using apache-tomcat-6.0.20.exe at path
TOMCAT_HOME=C:\Program Files\Apache Software Foundation\Tomcat 6.0. It is
running fine
Step 2 - Copied the contents of TOMCAT_HOME to new directory i.e. C:\Program
Files\Apache Software Foundation\Tomcat_instance2 (TOMCAT_HOME2)
Step 3 - Changed the ports (http, shutdown and ajp connecter ports) in
server.xml in TOMCAT_HOME2\conf
Step 4 - Set environmental variable CATALINA_BASE=C:\Program Files\Apache
Software Foundation\Tomcat_instance2 (There is no startup.bat in bin folder)

I start the tomcat from TOMCAT_HOME\bin tomcat6w.exe  In browser
http://localhost:8080/ runs fine but when I use http://localhost:8081 it
does not work.

Can you please help me how to run second instance of Tomcat on separate
port?

gc new capacity of JVM is gradually reducing when webapp(tomcat) started

2010-04-21 Thread 塗



hi,all

there is a problem with my webapp.

by manual configuration, i allocated 1G(1024M) memory for webapp.
where the gc new capacity automatically is 262M, the gc old capacity 
automatically is 699M, S0/S1 automatically is 43.6M/43.6M.


When my webapp is started, I use the jvm's own tools(jstat) to trace the 
garbage collections.
when the 6th Young garbage collection has happened, gc new capacity(262M) is 
gradually reducing.

About 10 hours after, gc new capacity is only 40.6M.

Re: mod_jk reply_timeout and error state

Hi Sean,

On 20.04.2010 08:04, Sean GAO wrote:

According to online documentation
(http://tomcat.apache.org/connectors-doc/generic_howto/timeouts.html):

Long Garbage Collection pauses on the backend do not make a good fit
with some timeouts. Try to optimise your Java memory and GC settings.


So if JVM tuning doesn't help, what else could I do? Balancer worker's
method=Busyness setting may have some effect, but still this is
different. What do you think?


There is no kind of soft reply timeout which would mean a long response 
time indicates we shouldn't send more requests to that Tomcat but should 
still wait for the outstanding responses.


The best you can do is tweaking the timeouts and the GC. Modern CMS GC 
doesn't do stop-the-world, most of it runs concurrently. Yes, after some 
time you might run into an occasional stop-the-world because of 
fragmentation, but they will be much rarer than without CMS.


If your GC stop times are about 30 seconds, then that is not good, but I 
wouldn't reduce a reply_timeout to something much smaller anyhows. You 
don't want to make the error detection very sensible, because then it is 
not unlikely that you end up making your system more unstable than 
without. You wan to detect serious problems and react on them but you 
shouldn't want to react quickly on any indication of possible problems.


What might help you a bit is the ability to define reply_timeout 
depending on the URL of the request. So if you know there are e.g. some 
reporting URLs that you know will take longet than a minute, you could 
set a general reply_timeout to e.g. 30 seconds, and the timeout for the 
report URLs to e.g. 2 minutes.


If you use reply_timeout, never forget to also add a max_reply_timeouts.

Concerning your configuration below, please do als consult

http://tomcat.apache.org/connectors-doc/generic_howto/timeouts.html

Hi,

We are running apache 2.2.4 and tomcat 5.5.28 with mod_jk 1.2.28. 3
tomcat instances.

Referring to http://tomcat.apache.org/connectors-doc/reference/workers.html
, we came up with a workers.properties file like this:

worker.list=balancer
worker.maintain=30
#tomcat01
worker.tomcat01.port=18009
worker.tomcat01.host=localhost
worker.tomcat01.type=ajp13
worker.tomcat01.lbfactor=120
worker.tomcat01.retries=2
worker.tomcat01.socket_timeout=30
worker.tomcat01.reply_timeout=3
worker.tomcat01.recover_time=300
#tomcat02
worker.tomcat02.port=28009
worker.tomcat02.host=localhost
worker.tomcat02.type=ajp13
worker.tomcat02.lbfactor=100
worker.tomcat02.retries=2
worker.tomcat02.socket_timeout=30
worker.tomcat02.reply_timeout=3
worker.tomcat02.recover_time=300
#tomcat03
worker.tomcat03.port=38009
worker.tomcat03.host=localhost
worker.tomcat03.type=ajp13
worker.tomcat03.lbfactor=0
worker.tomcat03.retries=2
#loadbalancer
worker.retries=2
worker.balancer.type=lb
worker.balancer.sticky_session=False
worker.balancer.method=Busyness
worker.balancer.balance_workers=tomcat01,tomcat02,tomcat03

So basically tomcat01 and tomcat02 are the main request handlers, with
tomcat03 acting as a backup server which is accessed only when both
tomcat01 and tomcat02 are in error state (30 seconds without response,
not necessarily mean offline). If something bad happens, e.g.
excessively long GC, or redeployment, we assume each failed tomcat
instance to get back to business in about 5 minutes.

This meets our needs to a certain degree. However, there's one thing
that bugs me:
If we set the reply_timeout too high, we miss the whole point of
fail-over. If we set the value too low, it's likely we are going to
kill a lot of legitimate/would-otherwise-success request, which is not
what we wanted either.

Instead of breaking the long request (say,>30 seconds) and put the
worker into "error" state, is there anyway, anyway at all, we can tell
mod_jk to mark a worker "busy", so that future requests are routed to
alternative workers? mok_jk can still check every 30 (or the default
60) seconds whether it is able to resume one of the "busy"-marked
workers, just like it does with the ones in "error" state.

Tomcat does not create gzipped logfiles.
I would venture that the most likely candidate for this is that you have 
a logrotate script which runs under cron from time to time, and which 
does it.
If you are under Linux, start with the /etc directory and look for 
anything that mentions logrotate, maybe starting in the /etc/cron.* 
directories.

Re: Tomcat fails on restart: BindException

2010-04-21 Thread Lara Spendier


hi,


/usr/local/tomcat6/bin/shutdown.sh
/usr/local/tomcat6/bin/startup.sh



The shutdown.sh script will probably return before Tomcat has completely
stopped running, which means that the startup.sh script will try to
start Tomcat before the previous instance has exited.
  

yeah, I thought so as well.


What does the log indicate when you're shutting down Tomcat?
How long does it take?
  
Good point, I have to look into this, but at the moment it is not 
possible for me to shut down the instance.

Maybe you have a problem that you're not aware of. A more recent
version of Tomcat may assist you with this, as it contains some
detection that adds messages to the logs when it finds potential
problems during shutdown.

Once you know how long it *should* take to shutdown, under normal
conditions, have a look at the usage statement of
/usr/local/tomcat6/bin/catalina.sh for some options on forcibly shutting
Tomcat down after a time limit.
  
Okay, then this is what I'm going to do next. Thank you very much for 
your quick response and your advice (also regarding the warnings etc.)!

Lara

(I need a coffee.)

So, I'm not asking the right questions here.  To recap:

1. What log files *are* being generated?  Are you getting
catalina.2010-04-01.log, catalina.2010-04-02.log etc?

2. If so, are they in addition to the catalina.1.tar.gz type files?

3. How big are is the compressed tar.gz and and how big is the file when
it's unpacked?

4. Did you post the entire log4j.properties or are there other parts to
it?  E.g. Are there MaxBackupIndex and MaxFileSize settings?  If not,
try adding one set to -1 and 0.

Description: OpenPGP digital signature

seperating content from the application

2010-04-21 Thread M.H.G. Emmerig



Hello

Our current configuration:

We are running tomcat 6.0.16 on windows 2003 enterprise.

We have a website which consists of an application part and a content part.
Both are in the same folder structure, eg.

webapps\Root\applicationfiles
webapps\Root\content\publications
webapps\Root\content\images

the application comes as a war file and the content is placed via another
process.

the folder structure is placed on a windows share.


Our current problem:

Whenever there is a problem with the share, the application crashes,
because tomcat can't find the application files anymore.
When the share comes back online, tomcat does not recover from the failure
and a restart is the only option.

Now I have the following questions:

I think separating the application from the content and placing the
application local to tomcat (basically on the same machine)
will solve the recovery issue.
I know placing everything local to the tomcat will be the best way and
gives the best performance, but at the moment that is not an option.

The questions

- Will placing the app local to the tomcat solve the recovery issue?
- Is there an easy way to seperate the app and the content, ie. some sort
of pathsetting ?

Sorry, my mistake, I misread your email.

Also:

seems to say that DailyRollingFileAppender isn't a good choice.

Tomcat doesn't tar & gzip files by default.  How are you starting
Tomcat, using a script like /etc/init.d/tomcat?

UTF-8 encoding in Tomcat 6.0

Hello,


I'm having trouble convincing tomcat 6.0 to take UTF-8 strings.
I created an encoding filter with no luck. 

/**
Here is the Utf8 Filter that fails for me in 
Tomcat 6.0.20 / Eclipse-Galileo / Windows Vista (6.0.6002) <---> Firefox 3.6.3.

Everything is on my  laptop (http://localhost:8060).

What I do is create a GET string (based on parameters from a

by script and send it (from Firefox) to the (localhost) server 
which is running under eclipse with a breakpoint in the EncodingFilter.

Re: Logging Requirement in Tomcat 5.5.16

Oops, type too fast. I want catalina.out to be rotate daily but Tomcat give
me extra files (catalina.out.1.gz, catalina.out.2.gz...catalina.
out.30.gz). I don't want those extra files. Any chance to disable that?

The extra files are generated by Tomcat by default? I do not specify those
file rotation anywhere.

You've configured a DailyRollingFileAppender with DatePattern
DatePattern set to ".-MM-dd" so the log files are being rotated daily.

What were you intending it to do?

Logging Requirement in Tomcat 5.5.16

Hi,

I am using Log4j logging in Tomcat 5.5.16 with JDK 1.5.0 update 7 on RedHat
Linux server.

I followed the instructions on
http://tomcat.apache.org/tomcat-5.5-doc/logging.html to copy the
commons-logging-1.0.4.jar and log4j.jar into $CATALINA_HOME/common/lib
directory.

and created log4j.properties in $CATALINA_HOME/common/classes directory as
below:

log4j.rootLogger=info, CATALINA
log4j.appender.CATALINA=org.apache.log4j.DailyRollingFileAppender
log4j.appender.CATALINA.DatePattern='.'-MM-dd
log4j.appender.CATALINA.File=${catalina.home}/logs/catalina.out
log4j.appender.CATALINA.threshold=info
log4j.appender.CATALINA.layout=org.apache.log4j.PatternLayout
log4j.appender.CATALINA.layout.ConversionPattern=%d:%p %c{2} - %m%n

After couple of days, I saw some catalina.out files suffix with ".x.gz",
where x is number range from 1 to 30. May I know to get rid of these files?

I only want log4j to handle the file rotation as configured in
log4j.properties.

Thank you.

Regards,
SamKong Goo

6.0.18 is getting on now, plan an upgrade of your server(s).

The shutdown.sh script will probably return before Tomcat has completely
stopped running, which means that the startup.sh script will try to
start Tomcat before the previous instance has exited.

You have a debug attribute on the Server element, remove it to clear
this error.

Same here.

There's already a service running on port 8081.
Check that the previous Tomcat actually shutdown completely.

You have a Servlet API jar in your webapp (you definitely shouldn't
have), remove it to remove this error.

As above, same error.

What does the log indicate when you're shutting down Tomcat?
How long does it take?

Maybe you have a problem that you're not aware of.  A more recent
version of Tomcat may assist you with this, as it contains some
detection that adds messages to the logs when it finds potential
problems during shutdown.

Once you know how long it *should* take to shutdown, under normal
conditions, have a look at the usage statement of
/usr/local/tomcat6/bin/catalina.sh for some options on forcibly shutting
Tomcat down after a time limit.

Re: JSESSIONID being lost

Hi Jim

There may be another mis-configured server out there that produces 
JSESSIONID cookies with a domain-wide scope. SAP portals are a known 
problem.


Best of luck

Subject: JSESSIONID being lost



I'm hoping someone may have some insight into a difficult problem we are
having.  We have a situation where the JSESSIONID seems to get lost
somewhere in a users transaction - the result is they get kicked back to 
the
applications login page (no sessionid so the app thinks they haven't 
logged

in).

Our current setup is two hardware load balancers (layer 4) in front of two
Apache servers (2.2.14) which sit in front of two tomcat servers (6.0.20).
The hardware load balancers load balance apache and apache load balances
tomcat using AJP via mod_proxy.  Apache and Tomcat are running on RHEL4
32-bit.  The JVM is 1.6.

This issue first popped up when we moved to the above architecture -
previously we had no hardware load balancers and only one apache server
balancing two tomcat servers (still with AJP via mod_proxy).  Initial
thoughts were that it had something to do with either the 2nd apache 
server

or the load balancers.

One way we have made this better (but not fixed) was to turn off one of 
the
tomcat servers so that requests could only go to one place - we thought 
that

the users session was being sent to the other tomcat server even though we
were using sticky sessions.  This was our temporary fix until we could
implement clustering, but today we found that users were still being 
kicked

back to the login page even with only one tomcat server running.  In the
interim we have turned off one of the apache servers to see if that helps
(so two hardware load balancers, one apache server and one tomcat server).

This problem is intermittent and almost impossible to reproduce, but it 
does

seem to happen more under heavy load.  Any insight would be very much
appreciated.  If it would help I can post our apache and tomcat
configurations.


Thanks in advance.
