 From: Christopher Schultz [mailto:ch...@christopherschultz.net]
 IMHO, you either
 have control of your production environment yourself (and can do
 whatever you want) or you have an ops team with complete
 control of your
 production environment (and they ought to be able to handle
 scary stuff
 like scheduling cron jobs and running shell scripts) or you have no
 control whatsoever and therefore do not have a production environment.

Chris, how would you handle the case of writing software for installation by 
third parties in environments over which you have no control?  Those third 
parties' environments are still production environments, but you have no 
control over them.

Wrong Time Shown in Catalina.out of Tomcat.

2009-02-17 Thread kashif_tomcat


Hi All,

These days i am facing a strange problem on Production Server. here is my
issue.

We are running tomcat 6.0.18 in QA and Production environment. 

ON QA Server, When i start tomcat, its catalina shows the same time as of
OS. 

[r...@qatest ~]# date
Tue Feb 17 10:04:53 GMT 2009
[r...@qatest ~]# tail -f /usr/local/apache-tomcat-6.0.18/logs/catalina.out
2009-02-17 10:04:38,333 INFO [com.


On Production Server. When i start Tomcat, its catalina shows time OS Time
+1 hour.

[r...@production ~]# /usr/local/apache-tomcat-6.0.18/logs/catalina.out 
2009-02-17 11:20:00,840 INFO [com.


i am unable to understand that why tomcat is not picking the time of OS to
put in Catalina.out and from where it is getting that time??? 

can anyone tell me that from where Tomcat reads this time to put in
Catalina.out. and what can be the reason of this wrong time in Catalina.out?

Thanks in advance.

Re: Wrong Time Shown in Catalina.out of Tomcat.

2009-02-17 Thread Ben Stringer

The Java runtime (JRE or JDK) maintains it's own timezone files. Most
likely there is a mismatch between the timezone for the OS and the Java
runtime (eg. daylight savings time).

Try installing the latest Java runtime and rechecking. For more info,
google for Java Olson timezone.

Cheers, Ben

Tomcat vs deflate

2009-02-17 Thread Gabor 'Morc' KORMOS


 Hi Guys/Gals,

 I tried to search for an answer whether Tomcat can support deflate as 
compression but I found nothing really except that it supports gzip by 
adding the compression parameter to the Connector definition. Is there a 
way to enable deflate besides/instead of gzip in any version of Tomcat 
(preferably recent ones, not 1.0 ;) ? If deflate is not supported then 
why not? Reason I need deflate is we use Adobe Air for an interface 
which receives a huge amount of XML data and it's not bandwidth 
economical to send it uncompressed and Air does not support gzip out of 
the box. Answers like use Apache instead of Tomcat as front-end web 
server can be spared.


 Thanks,

 Gabor 'Morc' Kormos.

Re: ssl_error_handshake_failure_alert

2009-02-17 Thread Siddhartha Purkayastha

It looks as if tomcat is configured for 2-way SSL. So the client (browser)
should have a certificate that the server can trust.
I think you could try to install a certificate from a good CA in your
browser truststore, and try using that.

I wonder if the other apps are running because tomcat selectively allows
apps to be 2 way ssl configured - I am not sure of this.

2009/2/17 gmail_ber berh...@gmail.com


 Hi all
 A colleague has set up a web app via https using tomcat on a server that I
 have access to.  When I try to access the web app via a browser (Firefox 3)
 from my own PC or from a browser (IE) on the server running the web app, I
 get an ssl_error_handshake_failure_alert error.

 Something else to note: I can access other web apps running on that same
 Tomcat on that same server (via https), but I just cannot access the one my
 colleage added.  He's on a week's leave as of today and I really need to
 access this web app!

 My question: how can i get the needed certificate to access this web app
 from my PC (bearing in mind that I have access to the server running Tomcat
 and the web app).  Can I check somewhere in the Tomcat conf directory or
 the
 webapp's directory for security settings or can I somehow export the
 certificate from the server and import it on my own PC?

 Thanks in advance.

Can support  - yes

Out of the box - no.

Why not out of the box? Because gzip is there and most people use apache

Re: Tomcat vs deflate

Sadly no. As I rethink the previous statement - I wonder how true it is. 
   For small self contained webapps - Tomcat is usually enough. But 
once you introduce clustering or use it as public face to the world, 
instead of a internal app - I would kind of expect apache to be out 
front to handle lots of the goofy issues that apache httpd is good at. 
(But now I venture into off topic my own opinion land .. and place where 
bad things usually happen)

Fatal error: Cleaner terminated abnormally

Hi Guys,

Our application is a servlet running in a container in Tomcat
standalone. It uses the following NIO connector definition:

Connector port=80
protocol=org.apache.coyote.http11.Http11NioProtocol
   connectionTimeout=65000 keepAliveTimeout=1
maxKeepAliveRequests=1000
   redirectPort=443 maxThreads=2000/

Lately we've been experiencing a fatal error, related to gc, with Tomcat
that causes it to stop and unload, which I hoped you could give some
advice for.

I'm still unclear on what is causing the cleaner to terminate, but I
guess that's more of a question for the java forums (I cannot find
anything related to tomcat when I cross reference)

Following the gc trail, it looks like an oom situation (maybe a mem leak
in our application, our heapsize is 4GB), is it normal behavior for
tomcat to destroy itsself like this?

Has anyone experienced a similar problem before? What are usual causes
for Tomcat to stop like this?

*Any* advice or feedback is welcome. Either way, thanks in advance.

Re: [OT] of the different methods to get a user-id

2009-02-17 Thread André Warnier

Just in case it was missed in the subsequent conflagration (and I always 
marvel at how easy it is to start a conflagration by saying something 
like language X is better than language Y), I would just like to state 
that my blurb was meant to be taken lightly, with ;-) and so on.


Comparing programming languages is a lot like comparing Microsoft 
software to Open Source, or comparing car brands, or (in my younger 
times) comparing stereo brands, etc..


One more thing I would like to add however to all the Java crazies 
around here, at least the open-minded subset of them : perl is fun.  I 
am not saying that it is the ideal language to develop a large 
application with a team of people, and I am not saying that it is faster 
or better or uses less memory or any of these things (though it does, 
really).  But it is, definitely, more /fun/ than Java.  And you can do 
serious things with it too.


And a serious tip : if you are ever in the situation of having to start 
a new project on some theme you know nothing about (say, credit card 
payments, or talking to Amazon, or filtering emails, or reading 
meta-data in photos, or stemming German words, or authenticating against 
OpenId,..), then you could do worse than first having a look at the Perl 
module library (http://kobesearch.cpan.org/), and perusing the perl 
modules documentation. Even if you know nothing of perl and don't want 
to know anything about it, the documentation of these (hundreds of) 
modules, all in one place and searchable, is one of the best sources of 
information I know.  It is like a Wikipedia of everything one can do 
with software.


And if in addition to be a Java fan, you're also an OO fan, search for 
class.  Don't the names just sound like fun ?


Is there, by the way, any comparable source for Java libraries ?

Re: Apache/mod_jk serves random files from tomcat

2009-02-17 Thread rnilsen

Hi,
We had similar behaviour on our server, apache in the front serving tomcat
on SSL, mostly servlets. First off, this is what we installed: Tomcat 5.5.27
and Apache 2.2.11 with mod_jk 1.2.26. The server is a 64 bit version of
Windows Server 2008 (2 CPUs). We got some strange problems with constant
high CPU usage. A thread suggested to change the tcnative.dll to an older
version since there was a bug in that, so we did and changed to version
1.1.6.0 (somewhere in the process we have misplaced the tomcat version this
file came with..) , and that got rid of the CPU usage problems.

But then another problem arose. After uploading documents into our system,
we could not download them successfully - this was first seen with PDF
files. And the larger the file, the more likely the problem. Then we noticed
that going directly towards Tomcat (on 8080) worked like a charm, so did
accessing static files under apache - but when trying the same static files
under tomcat - going through apache - it failed again.

We have tried different versions of mod_jk with no success, and experimented
with mod_expires settings etc. Then we got reports of issues where large
servlet generated reports got messed up, and it seemed the stream had just
left out parts of the produced HTML code, only to continue further down in
the expected report. And finally, to top it, we also got data from one user
showing up at another user!

After having no success we finally decided to try to remove the tcnative
DLL, and what do you know, it worked! No more problems with PDFs, and so
far, no more cut or mixed servlet response!

So what I want to know is, what could have caused this? My knowledge of both
Apache server and Tomcat is rather limited, so I hope someone can come up
with a good answer :)

We started restarting apache on a regular basis but if a user is in

I moved all static content to apache so tomcat is now only delivering
the actual jsp file. The result was that the mix up took longer to
appear, however when it did USERS STARTED SEEING EACH OTHERS DATA!!!
(before that, the mixup was usually with images etc just because
there are more of them).

I am actually amazed that this can even happen in such a mature
version and that such a small number of us are experiencing it. This
is slowly killing our project. Trying to move to proxy_ajp did not
help which makes the whole thing even more mysterious - these are two
separate code bases, no? (BTW - are mod_jk developers reading this?)

We are contemplating two approaches:
1) moving to proxy_http. My only concern is that this won't help -
maybe the problem is unrelated to AJP? Upgrading has helped some
users but not all and the problem exists in both mod_jk and proxy_ajp.
2) getting rid of apache and moving tomcat to the front (much harder
to configure but ensures we are rid of this problem).

Any Thoughts?

I suspect that it's related to 1.2.27 - I have been playing around with
older versions. .24 and .25 have had issues forwarding certain request
headers, but so far .26 seems to be working OK.

Is periodically restarting apache a suitable (if not hackish) work-

That'd be my fallback position.

Are you on a 64-bit JVM? If not, the process heap is limited to 4GB so the Java
object heap (set with Xmx) needs to allow for this. I would use 3.5GB as a

RE: Fatal error: Cleaner terminated abnormally

 From: Taylan Develioglu [mailto:tdevelio...@ebuddy.com]
 Subject: Fatal error: Cleaner terminated abnormally

 Lately we've been experiencing a fatal error, related to gc,
 with Tomcat that causes it to stop and unload

It's not really a GC problem - rather a silly bug in NIO.  You might try the 
standard HTTP connector to avoid the problem.  Sun seems to be continually 
fixing NIO, so there may be something for this in 6u12, if you want to keep 
using the NIO connector.

 I'm still unclear on what is causing the cleaner to terminate

The Cleaner terminates if the run() method of the registered object throws 
*any* kind of exception - and then takes the entire JVM down with it, via a 
System.exit() call (bloody brilliant, that one).  In this case, the NIO 
Selector Closer object didn't like the fact that its peer had gone away, and 
puked.  Not quite as robust as one might hope.

Re: Resource JDBC connection pooling USING LDAP

2009-02-17 Thread trames

Thanks, that is exactly what I did.

Since the documentation stated that it used apache (tomcat's version) dbcp
and the BasicDataSourceFactory, I looked at the source for this class
through SVN. It fairly simply creates a BasicDataSource. So that is what I
did. I retrieved all the parameters from LDAP within my factory class.
Worked out great.

Tomcat in-memory (session) cookie

2009-02-17 Thread makaira nigricans


Hello... 
As I understood (maybe I understood wrongly) with every GET and POST request
Tomcat generates cookie which it do not write on hard drive (so it cannot
be seen in browser cookie manager). It is some kind of in-memory (session)
cookie which is active only while browser's page is opened.
Does this in-memory (session) cookie exists? 
What exactly is bothering me? In one servlet I need to generate THIS cookie
(in-memory cookie which nobody can't find on hard drive) and than other
servlet will try to find that in-memory cookie and if this cookie exists and
caries one value (true) to redirect to one page and if it does not exits
only to inform user. So if this cookie exists can I edit it's value?
What I found by google and little experiments, JSESSIONID cookie. Is this
what I am looking for, JSESSIONID cookie? And I found also that you can set
session attribute with request.getSession().setAttribute(), get value with
getAttribute() . Is this what I am looking for? Is there any relationship
with all this? What are JSESSIONID, session, are those cookies?

You seem to be referring to HttpSession objects, which are not cookies.  
Session objects are created when a user is authenticated or when a webapp

Sounds like you need some basic education; try the servlet spec first:

Re: Apache/mod_jk serves random files from tomcat

2009-02-17 Thread Yuval Perlov

Is APR part of tomcat or apache? If I am running on linux and have  
no .so files in my tomcat directory does that mean I have no APR  
installed?


On a more positive note, we switched to proxy_http (after making the  
necessary code changes) and everything works now - no more mixed  
content.


Of course we lost a lot of necessary functionality:
1. request.isSecure() doesn't work
2. we don't know the server name we are hit with (since it is hard  
coded in httpd.conf)

3. we have no access to the source IP (for geo location)
4. We had to some make all  client redirection code use the full URL  
with the server name - turns out client redirect uses the server name  
from the request so it tries to hit the 8080 port (tomcat) instead of  
80 (httpd).


BTW - Am I the only one that is seriously worried that this kind of  
problem can even exist on a platform of this maturity?

The mixup occurs only in tomcat originated data - the static stuff
coming from httpd stays fine.


Good to know.


Moreover, in the past I had it setup so the static stuff came from
tomcat as well. This naturally resulted in significantly more hits
between apache and tomcat which made the problem appear much faster
(hence my theory that some resource is being depleted over time).


Is this something you can reproduce reliably in a test environment?  
Does
it require heavy load in order for this behavior to manifest  
itself? Or,

is it just after 5M requests everything goes to hell? I'm wondering if
concurrency is the problem or maybe something silly like logging or
maintaining worker status that somehow corrupts something.

It's very odd that responses would be crossed. I don't think any of  
that
stuff is shared between threads/processes in mod_jk/httpd, but I  
suppose

when you overwrite memory (which is the only explanation I can think
of), you can't really expect the program to operate properly.

Oh, are you using worker or prefork MPM?

 Our application is using a SSL connection to communicate with Tomcat.

If we were using a browser I might expect to see a connection denied

response or an invalid certificate message in the Tomcat logs.

SSL does not allow or deny connections by itself, it's just a means to
verify the validity of the connecting party.It is upto the
implementation to
verify if the certificate is valid.
SSL operates on top of IP and encrypts all traffic whether the other
party
is trusthworty is up to the application that is setting up the
connection to
determine. Certificates are a means to verify the other party is who
they
say they are by means of acknowledgement of a recognized authority.
If you wan't your application to deny the connection if the certificate
is
expired, the application must be written to do so.

Hope this helps,

RE: Tomcat in-memory (session) cookie

2009-02-17 Thread Jorge Medina


Hi Makaira, 

I also found hard to understand the concept of sessions and its relation
to cookies. After all, HTTP is a stateless protocol, right?

Well, a servlet engine (as stated in the Servlet Engine specification
pointed by Charles) must provide a way to provide some state. This is
done by a special cookie with the name JSESSIONID. This value is passed
back and forth between the client (a browser) and the server. If the
request has the cookie JSESSIONID, then the server looks for the active
sessions and joins the request to that session.

 My confusion came from the fact that through the HttpSession object,
you can access the cookies with methods that names then Attributes
(getAttribute/setAttribute). It was unclear -to me- that it is the same
stuff as a cookie. 

The JSESSION attribute is handled by Tomcat, you don't have to set it.
It is enough to add the attribute(s) you will later use.

By the way, cookies are stored -as files- by the browser just to persist
them and made them available later on; but a cookie is not neccesarily a
file; certainly, you won't find them in the server filesystem, they live
only in the Tomcat memory.

Thanks Chuck and Jorge...

My English is not so great and maybe my questions did not had good
grammatical form. 
Chuck thanks for answer, and I know what cookie is :) but I was confused...
Just for practice I created two jsp, one calls another through form tag. And
after that I created one servlet who prints all cookies. Than for experiment
I run jsp A who on-click called (opens) jsp B, than after that I run servlet
C to print current cookies and it printed JSESSIONID cookie. 
I was confused what is relation between session (HttpSession) and JSESSIONID
cookie because JSESSIONID has session in it's name and through my
cookie-printing servlet I saw that JSESSIONID is cookie? And is there
in-memory cookie which generates on every get and post request? 
I thought that this Tomcat in-memory (session) cookie which I am looking
for is JSESSIONID. I could print it value but I was wondering could I change
it value? Or add more values to this cookie?
In manual Chuck gave me I found this: Session tracking through HTTP cookies
is the most used session tracking mechanism and is required to be supported
by all servlet containers. The container sends a cookie to the client. The
client will then return the cookie on each subsequent request to the server,
unambiguously associating the request with a session. The name of the
session tracking cookie must be JSESSIONID. So after my all my dilemmas
JSESSIONID is simple cookie! But I still do not know is this the cookie
which exists only when browser is opened because I closed browser and run my
cookie-printing servlet which printed this cookie again?!
Jorge, thanks, you cleared some of my dilemmas but I still have few... :)
You said that through the HttpSession object I can access the cookies and
you said and that JSESSIONID attribute is handled by Tomcat but you said It
is enough to add the attribute(s) you will later use. Does this means that
I can add more values to JSESSIONID cookie?!
If I can this is great, it solves my problem, I can check with my second
servlet is JSESSIONID present and I can check does it contains my value and
if it does I redirect, if it doesn't I inform user.

Thanks Chuck and Jorge...

My English is not so great and maybe my questions did not had good
grammatical form.
Chuck thanks for answer, and I know what cookie is :) but I was confused...
Just for practice I created two jsp, one calls another through form tag. And
after that I created one servlet who prints all cookies. Than for experiment
I run jsp A who on-click called (opens) jsp B, than after that I run servlet
C to print current cookies and it printed JSESSIONID cookie.

 Subject: Re: Fatal error: Cleaner terminated abnormally

 search the sun database, some results there
 http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6521677

It's somewhat related, but I don't think it will cover the case reported here, 
which looked like a simple socket closure rather than anything to do with 
memory mapping of files.

I think a new bug submission is in order (preferably by the OP).

RE: Tomcat in-memory (session) cookie

 From: makaira nigricans [mailto:liame.e...@yahoo.com]
 Subject: RE: Tomcat in-memory (session) cookie

 And is there in-memory cookie which generates on every get
 and post request?

First, let's do the terminology: there's no such thing as an in-memory 
cookie.  A cookie is just a piece of information passed back and forth between 
a client and a server that preserves state information for an otherwise 
stateless connection.  Clients (browsers) usually persist cookies on disk, but 
Tomcat and webapps running therein don't know or care about that.

What Tomcat keeps track of is the HttpSession object, one attribute of which is 
the JSESSIONID value.

 Or add more values to this cookie?

To repeat: it's not a cookie, it's an HttpSession object.  If you look at the 
servlet spec and the API doc for HttpSession, you'll see the setAttribute() and 
removeAttribute() methods, which you may utilize as you see fit.  If you want 
to send additional cookies to the client, you'll need to use the addCookie() 
method of HttpServletResponse, again documented in the spec and API pages:
http://java.sun.com/products/servlet/2.5/docs/servlet-2_5-mr2/index.html

 You said that through the HttpSession object I can access
 the cookies

No, he said you can access *attributes*, not cookies.

 Does this means that I can add more values to
 JSESSIONID cookie?!

No, but you can add more attributes (names and values) to the *session* object.

RE: Fatal error: Cleaner terminated abnormally


Sadly there is no mention of a fix related to NIO in the 6u12 release
notes. This comes as kind of a bummer, as we were hoping to make a comet
implementation soon.

The native/apr connector looks like it could be a replacement for NIO
for us, but after searching I could not find anything conclusive about
the scalability and performance compared to NIO. 
Opinions on native vs nio in discussions I have found seem to be
divided.

I'm also not sure if the native/apr implementation is completely
separate from the NIO api.

Does anyone know of any downsides/pitfalls I should look out for when
using native/apr ? 

As always, any comment is appreciated.

 Subject: Fatal error: Cleaner terminated abnormally

 Lately we've been experiencing a fatal error, related to gc,
 with Tomcat that causes it to stop and unload

It's not really a GC problem - rather a silly bug in NIO.  You might try
the standard HTTP connector to avoid the problem.  Sun seems to be
continually fixing NIO, so there may be something for this in 6u12, if
you want to keep using the NIO connector.

 I'm still unclear on what is causing the cleaner to terminate

The Cleaner terminates if the run() method of the registered object
throws *any* kind of exception - and then takes the entire JVM down with
it, via a System.exit() call (bloody brilliant, that one).  In this
case, the NIO Selector Closer object didn't like the fact that its peer
had gone away, and puked.  Not quite as robust as one might hope.

Are you on a 64-bit JVM? If not, the process heap is limited to 4GB so
the Java
object heap (set with Xmx) needs to allow for this. I would use 3.5GB as
a
starting point.

Since we put this change into production, we haven't seen the problem.
