Re: HELP with my first webapp thats live!

[Yucca Nel]

Yes you idiot it's easy to point me to google to google for a jsf tutorial. 
wELL they are all broken as is tomcat. During development I tested a hundred 
times and it worked on my machine. I used relativ links through combinations 
of command links and outputlinks  and they still work. But online my app is 
throwing 404 errors. I understand that jsf by default does a forward and 
therefore any new request by default is done from the same browser context 
as the last request. I have tried doing redirects in fsces config using 
keep http://www.lmgtfy.com/?q=jsf+tutorial because the information I find 
there is not helping.

Re: Keeping tomcat up-to-date on linux

[Harry Metske]

I agree with Hassan,

our reasons to use the tar.gz install method :

* in most serious Tomcat environments you need more control over the
installation and configuration than the distro managed version offers.
* most distro's (especially RHEL) are lagging behind, so you don't get the
latest stuff you need
* we also keep an eye on this list and the tomcat website for updates, and
for security patching we use some sort of subscription service from McAfee,
so that should tell us if there are any security patches that need to be
applied quickly.
* it is usable and the same for all platforms we use
* makes the separation of duty easier with our Linux administrators, at
least I am sure I don't get unsolicited updates to my tomcat installations
when they run an update on every package on every linux box
* we run multiple Tomcat instances on the same OS image, that is not what
the disto is facilitating
* better open source support

But the distro packaged version could be very usable for the masses and
non-pro use.

my two cents

Harry

Re: Keeping tomcat up-to-date on linux

[Thad Humphries]

Exactly right, Hassan. I think it is extremely unwise to leave any critical
portion of one's system--personal, development, or production--at the hands
of the distro. I've used Linux for over a decade, and install Apache, Java,
Tomcat, etc. by hand. ALWAYS. Oft times I build Apache myself.

Don't remember, actually; I've been using pretty much the same
basic version for a long time. I mean, it's just a shell script, eh?

As a consultant, whatever the client's running; my own dev desktop
system is SuSE, my own production server is RHEL, and I've got a
couple of different Linux VMs on my MBP for testing. That changes
periodically. And of course I'm running multiple Tomcats on the Mac
too :-)

Which, now that I think of it, is a good reason to install from the
tar file; it's the same everywhere. I don't have to use "yum" here,
"rpm" there -- the same simple drill works *everywhere*.

Obviously, your situation sounds quite different from mine :-)

RE: Keeping tomcat up-to-date on linux

[Dale Ogilvie]

 
Yes, the release gap is an issue for me as well. Hence this email trail
:-)

Parallelism is achieved for us for other software by package updating
the test/dev server and testing that prior to performing the same
updates on prod. There is no need for us to have two versions of tomcat
running on the same host. So, if the package manager would just stay
up-to-date with tomcat releases it would mean we wouldn't have to have
special practices for Tomcat 6.

I'm pleased to hear that the upgrade process is trivial with your setup.
If you're going to have special practices, they might as well be simple.

On what did you base your init.d scripts? And what is your underlying
distro? We use redhat/fedora.

I don't recall ever having to change anything but the paths in the init.d
script, but yes, I do use `tar xvfz` to install. Which means I can install in
parallel to any other running instance(s) and test before cutting over.

The inability to do that with any package managers I'm aware of, plus
the release gap, is why I don't bother with them. Untarring a file just
doesn't seem all that onerous to me.

I'm hoping for something a bit more distro managed. Presumably your
method means you have to maintain your own init.d scripts and use the
"tar xzvf" method of installation, outside of your distro package
management system.

On Windows, I at least have an installer that takes care of these tasks
for me.

Keeping tomcat up-to-date on linux

[Dale Ogilvie]

Hi,

The current release is 6.0.26, March 2010.

RHEL5.x is running with Tomcat 5.5.

Fedora 12 is on 6.0.20, June 2009 vintage. 

Ubuntu 10.04 is on 6.0.24 from Jan 2010.

Ideally, the equivalent of a "yum update" would track tomcat releases so
that soon after a tomcat release the tomcat6 package would move to the
next minor release. Does this happen for any distro out there?

What do people do to keep their tomcat patched up?

Thanks

Dale

Re: too man open files?

[Licht Jiang]

Thanks for your help. I found out that actually those 3 xml files:
._Push.xml, ._host-manager.xml and ._manager.xml should not be there.
There were there may be because an unexpected termination of tomcat. I
deleted them and actually removed Push.xml as well and everything goes
back to normal.

Re: Question on workers.properties file

[savoym]

Yes.  The users are already being authenticated by IIS before IIS forwards
the request to Tomcat.  And yes, I am wanting to retrieve in my java app
this userid from what I thought would be through the HttpServletRequest
class.  However, that is not working.  I tried to retrieve it using this
class on the header Authorization but I am still getting a NULL value. 

I understood, that maybe through the workers.properties file I could SET a
server environment variable using the Request.ServerVariable("AUTH_USER")
method but I'm not sure how to accomplish that if that is a possibility.

I guess I'm just not sure how to get at the USERID that IIS should already
have in some form or fashion.

I hope that is more clear.  I appreciate very much the question and reply.

Regards.

Again, something that is easy to fix if you are using mod_proxy rather
than mod_jk.

You should be able to use mod_headers to re-write the cookie header on
the way back to correct the path.

Can you explain a little bit more in detail, or maybe just in another 
way, what you are trying to achieve ?
Are users already authenticated by IIS (as per their Windows Domain 
user-id), before IIS forwards the request to Tomcat ? And do you want to 
retrieve this user-id in Tomcat ?

Re: Question on workers.properties file

[savoym]

Ranier,

Thank you for the clarification.

As far as your instruction, let me ask the following if you don't mind:

What source are you referring to?  Do you have a URL for this source?

Also, I've been trying to pickup this "AUTH_USER" from the
HttpServletRequest.  Is that not where I can pick it up from?  I thought I
could access it from the client request via the tomcat connector but I did
not know how to do that.  

That is what I'm trying to get at to pass into my authentication method. 
Again, any help/direction would be greatly appreciated.

Thanks again so much.

Any idéas?


Yes: emptySessionPath does two things:

- it sets the cookie path to "/", so that all contexts receive the same 
same session cookie
- if a context gets a cookie and doesn't already have a session with the 
requested ID, it creates a new session with the requested ID.


The second feature is where it fails for you, because now the jvmRoute 
is wrong.


I would try working around using a servlet filter, but I'm not sure, how 
early in request processing emptySessionPath kicks in.


There is a patch proposed for inclusion in TC 6 to make the session 
cookie path configurable. Not unlikely it will make it into 6.0.27. You 
can have a look at


http://people.apache.org/~markt/patches/2010-05-18-bug48379.patch

Rainer

mod_rewrite to change the url:s of the backend application. Otherwise we
get a JSessionID with a "/path" rather than "/".

When I removed the emptySessionPath we got back a new cookie with the
correct route. When I have it on I get no sessionId back at all. So the
solution would be that the root-context and my application should have the
same JSESSIONID (is it possible) or I can deploy my applicaiton in the
root directory.

Hi,

We are load balancing 3 non-clustered tomcat 6.0 servers with the mod_jk

round-robin between the other two since none of them wants to accept the
JSESSIONID with the route of the crashed tomcat server.

How can I make one of the other servers to create a new session with its
own
jvmRoute for that tomcat? Because right now we have a huge problem when
taking down a server for maintenance. The user will change server on
each
request until the server that is down for maintenance is back up again.

Do we really have to setup the tomcats in a cluster to accomplish this?


Not sure I understand the real problem. If the app does "not accept" the
sessionid, I would expect it to create a new session (and a new
sessionid) using the correct local route.

Do you use emptySessionPath in the connector configuration inside
server.xml?

Can't you add a simple servlet filter overwriting the JSESSIONID cookie
if it's route doesn't match the local route?

Rainer

The source says: we forward GetServerVariable of "REMOTE_USER" to
Tomcat. in order to let Tomcat trust the forwarded auth data, you have
to set tomcatAuthentication="false" as an attribute on the connector
element in server.xml.

Microsoft docs say: AUTH_USER:  

The name of the user as it is derived from the authorization header sent
by the client, before the user name is mapped to a Windows account. This
variable is no different from REMOTE_USER. If you have an authentication
filter installed on your Web server that maps incoming users to
accounts, use LOGON_USER to view the mapped user name.

but it doesn't work.


That's not a file that supported versions of Tomcat are aware of.

Re: Question on workers.properties file

[savoym]

Ranier - Thanks for the reply.  I have some questions on your response.  The
INT value that your get_server_value method returns how do I determine from
that what the userid is and more importantly, what calls this method and
populates the values for this method to run?

Sorry for the ignorance.

Thanks again.

What does "each" mean?  Is the system running with 4 GB of memory or something

When you do an export of a variable, followed immediately by a set of the same 
variable, what do you think happens?  (The exact effect depends on the shell 
you're using.)

Because your CATALINA_OPTS settings are not visible.

Again, why do you think it's an error?  Have you compared that catalina.out 
with a normal Tomcat startup?

Is there anything else of interest in the logs (not just catalina.out)?

Re: Tomcat Jconsole

Hi,
Again:

-Rhel 5.3 x64

-java version "1.6.0_16"
Java(TM) SE Runtime Environment (build 1.6.0_16-b01)
Java HotSpot(TM) 64-Bit Server VM (build 14.2-b01, mixed mode)

-Apache tomcat 6.0.26

-Dual core Intel(R) Xeon(R) CPU E3110  @ 3.00GHz  and 4 GB memory each.


The startup.sh configuration is not broken. I didnt wipe out anything.

It is not firewall

Im using nmap and netstat to see the connecions open. I do not see the port
open in local, I do not see the port open, logically  from remote.

The error in catalina.out comes up when I add  the jxm options. Since it is
in Catalina.out I am asking if it is important..


Any more ideas?

I'll concentrate on that same one too.

We have an issue on some systems, which may be similar.  Sometimes the 
system becomes apparently incapable of responding to TCP connections at 
all, and we have linked this to a high number of connections in the same 
CLOSE_WAIT state.  In our case, they are due to a webapp (of which we do 
not have the source), which allocates some kind of "connection object" 
which itself contains a socket.  When the webapp terminates, it discards 
this "connection object", but does not previously close() the socket.
These objects then sit on the Heap until the next GC, and meanwhile they 
keep their socket in the CLOSE_WAIT state.
When there are "enough" of them in that state, we start having severe 
problems on the system with other applications needing to connect to, or 
from, the system. ("enough" is a vague number ranging from hundreds to 
thousands, depending on the system).
Triggering a GC of Tomcat solves the problem, immediately : the 
discarded objects get cleaned up, which frees the underlying sockets, 
and the CLOSE_WAIT list disappears, and the system is back to normal.


I am not the great authority in those matters, but intuitively I would 
imagine that a socket is an OS-level structure, and that it uses some 
system resources, like RAM.  And if you have thousands of them lying 
around, it may matter.


The funny part about this, is that if you increase the Heap size, you 
actually make the matter worse : there will be more room for these 
discarded objects, delaying the time when a GC would occur.  So you can 
accumulate a lot more of them, and freeze a lot more resources with them.


To force a GC, one useful command line tool is available here :
http://code.google.com/p/jmxsh/

clustering errors in 6.0.26 with multiple contexts

[Ronald Klop]

Hello,

Since I'm running 6.0.26 I have clustering errors on startup of some contexts. 
I only see this on servers with multiple clustered contexts. I don't know if 
that is related.
In 6.0.24 everything worked ok for months.
Today I caught the stack below on startup after which I get a 60 second timeout 
on sessionreplication. Can this be anything which has changed in 6.0.26?

Ronald.

Problem with IIS 7.0 plugin isapi_redirect on Windows 2008 64 bit

[Ganesan, Chandru]

Hi

I'm trying to configure the IIS 7.0 with latest isapi_redirect.dll (Ver 1.2.30) 
on Windows 2008 Server (64 bit). When I try to login to the Apache Tomcat 5.5 
Servlet container, it fails with
the error:

404 - File or directory not found.
The resource you are looking for might have been removed, had its name changed,
or is temporarily unavailable.

Also I don't see any logs getting generated in isapi.log file, so I'm at a loss
as to the root cause of this issue. I don't see isapi_redirect.dll getting 
loaded, however I notice isapi.dll being loaded.


Attaching isapi_redirect.properties file below. Thanks in advance for your 
input.


# The path to the ISAPI Redirector Extension, relative to the website
# This must be in a virtual directory with execute privileges
extension_uri=/jakarta/isapi_redirect.dll

# Full path to the log file for the ISAPI Redirector

# Log level (debug, info, warn, error or trace)

You shouldn't be modifying startup.sh; create a setenv.sh script to contain 
environment variable manipulations.

The above looks very broken: you've wiped out the heap size and -server

JMX requires use of additional ports that are normally dynamically allocated; 
likely that your firewall is blocking them.  If you're running on a current 
version of Tomcat, look here to get around the problem:

http://tomcat.apache.org/tomcat-6.0-doc/config/listeners.html

See the section describing the JMX Remote Lifecycle Listener.

> When I start tomcat I do not see 8999 open.

Tomcat Jconsole

[Ozgur Ozdemircili]

Hi,

Im trying to connect to my tomcat server using Jconsole. I do get
"Connection Failed"

I have the following parameters in my tomcat startup.sh

export CATALINA_OPTS="-XX:MaxPermSize=512m -Xms512m -Xmx2048m -server"
 set CATALINA_OPTS="-Dcom.sun.management.jmxremote \
-Dcom.sun.management.jmxremote.port=8999 \
-Dcom.sun.management.jmxremote.ssl=false \
-Dcom.sun.management.jmxremote.authenticate=false"

And My hostname resolves to my ip:

hostname -i
10.5.xx.xx

I can connect locally by openig vnc conneccion yet when I try from my
workstation it does not connect.

When I start tomcat I do not see 8999 open.I see the following error on my
catalina out:

java org.apache.catalina.startup.Catalina [ -config {pathname} ] [ -nonaming
]  { -help | start | stop }



Any ideas why I cannot connect remotely?

will be thrown to the wind.  Thus, instead of relying on tomcat to manage my 
session, I am instead managing the session via manual cookies and a database.

Being that I cannot leverage the tomcat session, I don't want to create a 
session at all.  This has a two-fold benefit:

1)  Slight performance increase due to avoiding session creation overhead

2)  I can put a session listener in place to log an error if ever a session 
is created, to ensure that we are not using the tomcat session in the 
development environment where everything would appear to be fine until we 
deploy to the cloud.

According to JSP spec, I believe I should be able to use the following 
directive to prevent a session from being created by my JSPs: <%@ page 
session="false" %>.  However, even when doing so, I am still getting a session 
created by the internals of the JSP container.  Is there something I am doing 
wrong?  Is it possibly a bug in Tomcat 6.0.24 (couldn't find it on Bugzilla)?  
Or is it simply a "necessary evil"?

The generated JSP code that is triggering the session is:  pageContext = 
_jspxFactory.getPageContext(this, request, response, null, true, 8192, true);

Below is the relevant portion of an exact stack trace:

CORBA and Tomcat

[privat]

Hello,

Does somebody know something about this:
java.lang.SecurityException: ORBSingleton: access denied

com.sun.corba.se.impl.orb.ORBSingleton.string_to_object(ORBSingleton.java:348)


I tried to connect to a CORBA-NameServer by using
a Servlet on Tomcat.

I also grant all premissions in the webapps.policy, but it doesn't work.
Thanks for your help.

What version of c3p0?

What JVM?

What platform?

Are you running with a security manager?

The above would indicate that the version of c3p0 you're using is not quite 
spec compliant.

Is there anything else in the logs, such as a stack trace?

You'll never be able to get that many threads going on a 32-bit Windows system. 
 You need to scale it down to something reasonable (like the other config).

You're not out of RAM, you're out of virtual space for the process.

No; I'm not aware of it being shown anywhere.

It's reserved for the Java heap.

OK, so one possibility is that the Windows thread table is full.

That's a huge number of threads for one process.

That's merely massive.

That has nothing to do with threads.

Yes.  But that's not the error you're getting.

Task manager, Processes tab, View, Select Columns..., tick "Thread Count".

You are reserving heap and permgen memory when the JVM starts.  Thread
memory, and kernel resources for threads, are outside of this total.

That has nothing to do with threads (and CLOSE_WAIT is a feature of
TCP, not of threads).  That link contains no information about
increasing the maximum number of threads in Windows.  It links to
TCP/IP tuning.  Wrong link, or wrong assumption?

That has nothing to do with threads.

> Does anyone have an idea to get rid of the exception?

*Decrease* the number of threads in use in Tomcat 1.  If you set the
HTTP and JK maxima to the same as Tomcat 2 (which is still very
large), what happens?  Why?

Tomcat 6.0.20 "unable to create new native thread"

[tomcat]

Hi all,

we have a problem with our tomcat 6.0.20 which throws occasionally the 
following exception:
java.lang.OutOfMemoryError: unable to create new native thread
 
Information about the system:
- Win2003 Server Standard Edition 32 bit
- 2GB RAM
- Apache 2.2.13 with open SSL and mod_jk 1.2.28 for the communication with 
tomcat
- 2 instances of tomcat 6.0.20 on different ports. No redundancy / clustering. 
Each tomcat serves different webapps.
- JDK 1.6.0_06

Only one tomcat throws the above noted exception.

Configuration-Details:
- Tomcat 1 (with the problem)
   - MaxPermSize=256m
   - JvmMs 128 
   - JvmMx 768
   - maxThreads for HTTP: 450
   - maxThreads for jk: 3000

- Tomcat 2 (no problem yet)
   - MaxPermSize=256m
   - JvmMs 128 
   - JvmMx 512
   - MaxThreads for HTTP: 800
   - MaxThreads for jk: 450

When Tomcat 1 was throwing the exception the server status was showing the 
following:
   - mem Free  116 MB
   - mem Total 242 MB
   - mem Max   739 MB
   - current Thread jk355
   - busy Threadjk333
   - current Thread HTTP  5
   - busy ThreadHTTP  3

   - all connections shown by netstat -an (not filtered): 4595
   - connections in state close_wait: 3152

The tomcat was not totally stuck. Already connected sessions seemed to have no 
problem, but new sessions (new login) threw the exception and did could not be 
created. The Taskmanager shows that all in all 1.39 GB of RAM are used - much 
below the 2GB Limit. 

On the other hand: Shouldn't  windows start to swap if the ram is full?

In which memory-area does windows handle the memory which is used for the 
threads? Is it shown in the taskmanager?

Can the OS take the mem which is still unused by the JVM (memMax-memTotal) for 
handling threads or is it reserved for the JVM after starting tomcat?


Due to problems with one of our webapps which sometimes does not close the 
threads completely (they stuck in close_wait-state) we increased the max 
threads of windows:

http://publib.boulder.ibm.com/infocenter/pvcvoice/51x/index.jsp?topic=/com.ibm.websphere.wvs.doc/wvs/tun_conwin.html

maxUserPorts have been set to about 30k if i remember correctly.

Does anyone have an idea to get rid of the exception?

kind regards,
Andreas

C3p0 datasource

[Woude, Alexander van der]

Hello guys,

I have some trouble in getting c3p0 ComboPooledDataSource working in Tomcat 
6.0.26.

I have the following config in my server.xml:





 



During startup of the server things already go wrong. 
In the http://localhost:8080/manager/resources I get an error.

the error is : 
FAIL - Encountered exception javax.naming.NamingException: Could not create 
resource factory instance 
[Root exception is java.lang.IllegalAccessException: Class 
org.apache.naming.factory.ResourceFactory 
can not access a member of class com.mchange.v2.c3p0.DataSources with modifiers 
"private"]

Any ideas?

Regards
Alexander

Re: Jmxproxy issue

[Anurag Kapur]

>From what I know, you do not get detailed memory information on the jmx
proxy servlet without the JMX agent enabled.

You can enable it by adding the following JVM argument.
-Dcom.sun.management.jmxremote

I have tested this on Tomcat 5.5.27 with Java 1.5.0_14. With the above JVM
argument added to the Tomcat process you get detailed memory information
including Garbage collections stats on the jmxproxy servlet.

Hope this helps.

Re: JAAS getRemoteUser security custom

[Neville Peter]

Hi,

I'm still not satisfied with the options so far and I'm sure I do not fully 
understand it:

Although the valve works in that I can set the principal on the catalina 
request, realm.authenticate("username","credentials") within the valve is not 
actually passing anything to my JAAS login module although the login module is 
being used. Therefore, I can not currently authenticate the user within the 
JAAS module correctly as there appears to be no data passed from the valve. 
Also, if I use the valve then what is the point of the servlet using 
LoginContext.login()?

If I choose not to use a valve then I appear to not have any access to the 
request object within JAAS. 
Even if I use org.apache.catalina.realm.JAASCallbackHandler, I do not get 
access to the request. So how are you able to add the principal to the request 
like you can do with the valve?

SecurityFilter not an option as it does not support SSO.

Thanks for the comments so far.

Because the first thing that that Valve does is to look if clustering or
a persistent manager is configured and does nothing neither is the case.
Hence my previous response. See the source code for details.
