Hi,

At my company we can see NullPointerExceptions in the catalina.out files (see 
the attachments). We use Tomcat 6.0.14 on our 4 servers to handle web service 
calls from another tier of the application. The errors occur when the soap call 
was processed and ready to send the prepared response back to the clients. The 
errors force the web services client framework to resend the same soap request 
to the Tomcats when they are processed again. Some of our web services treat 
this as a business logic failure.

We can't reproduce the issue on our test and development environments, it is 
appearing only on the production environment. The errors are seen usually 1-2 
servers. When we restart the tomcats the errors can disappear from a server, 
but it may appear on another. The first errors were appeared after a restart of 
the platform, there were no new application deployed or configuration change 
made. Before the errors the same version of the application was running more 
than one and half month without problem. Different versions of the application 
was running fine for more than a half year.

Tomcat developers gave me a hint to try the 
org.apache.catalina.connector.RECYCLE_FACADES=true system property to avoid 
reuse of request and response objects, but it was not working.

We have no idea what can cause this. Can the clients cause the error?
I hope someone can help me find a solution for this issue.

The above is the spot you should be looking at, since that's the only stack 
entry for your code.

One possible problem is incorrect variable scope, such as using a static or 
instance variable in a filter or servlet when you should be using a local one.  
Static and instance variables are shared by all requests, so any concurrent 
threads using them can trip each other up.  The same issue applies to 
request-specific information being stored in a session while multiple requests 
are being processed.

RE: NullPointerException in MimeHeaders

Hi,

That piece of code was not changed since 2008 March and the application was 
working fine with this code more than half year.
I can't see any suspicious in that class, maybe you can:

public void doFilter(ServletRequest request, ServletResponse response,
FilterChain filterChain) throws IOException, ServletException {
if (isMetadataRequest(request)) {   
log.info(Metadata request (wsdl/xsd) received, performing 
synchronization.);

synchronized (lock) {
filterChain.doFilter(request, response);
}
} else {
filterChain.doFilter(request, response); // row 54
}
}

private boolean isMetadataRequest(ServletRequest request) {
return request.getParameter(wsdl) != null || 
request.getParameter(WSDL) != null ||
request.getParameter(xsd) != null;
}

Cheers,

Bertalan Kis

RE: one webapp - two security constraints

 From: rjgallac [mailto:rgallac...@ufi.com]
 Subject: one webapp - two security constraints

You didn't bother to tell us the version of Tomcat you're using, so the 
following comments are based on using a 6.0.x level (but should also apply to 
5.5.x).

 Host name=host1 appBase=webapps/files unpackWARs=true

The appBase setting is wrong; it should be just webapps, not webapps/files. 
 Having appBase the same as any docBase is illegal.

 Context path= docBase=${catalina.home}/webapps/files

It's really, really bad form to put Context elements in server.xml.  In 
addition, the above gets you *two* deployments for this Host, since the 
webapp will be deployed once as ROOT, and again as files.  Name the webapp 
directory or .war file ROOT (case sensitive), move the Context element to 
webapps/ROOT/META-INF/context.xml where it belongs, and remove the illegal path 
and docBase attributes.

   Host name=host2 appBase=webapps/files

Ditto.

 Context path= docBase=${catalina.home}/webapps/files

Ditto.

 So the question is two hosts. One web app.

No, you actually had four webapps, since there was double deployment for each 
Host.  Each Host will *always* have a separate copy of the webapp, even if 
they point to the same appBase.  (BTW, having two Host elements using the 
same appBase is a tad risky if you ever try redeployment on the fly.)  You 
cannot have multiple Host elements sharing a webapp in memory - it simply 
doesn't work that way.

You could use SecurityFilter to keep just one copy of the webapp and have that 
filter check for whether or not to apply the security constraint.  Look here 
for details:
http://securityfilter.sourceforge.net/

Maybe, but I think this means that we should see the errors on all the servers 
and not only some of them.
Currently we have 2 servers with errors and 2 without errors. It will change 
when we restart tomcats.

Threadlocal problem

2010-02-02 Thread Malcolm Warren

SEVERE: A web application created a ThreadLocal with key of type 
[org.apache.commons.lang.builder.ToStringStyle$1] (value 
[org.apache.commons.lang.builder.tostringstyl...@66a37d72]) and a value 
of type [java.util.HashSet] (value [[]]) but failed to remove it when 
the web application was stopped. To prevent a memory leak, the 
ThreadLocal has been forcibly removed.




I get this message with every hot redeploy, which is a little worrying. 
Anybody know what it's about?


This started with the latest Tomcat 6 version: 6.0.24.
I'm pleased with this new version because it also pointed out politely 
that I hadn't closed a thread I'd opened.


I've fixed my Thread but I still get the message shown at the beginning

I don't use ThreadLocal in my code at all, so it's Tomcat who's creating

I can't do much about, presumably.




Thanks for any help you may be able to give.

It isn't Tomcat's (Tomcat doesn't ship with commons-lang) so I am pretty
sure it is yours. Chances are it isn't something you are doing directly
but maybe something a library you are using is doing?

If a library is adding a ThreadLocal to a request processing thread it
*must* remove it before the request completes to avoid a potential
memory leak. If it doesn't, I would argue that is a bug in the library.
At a stretch, if the library provides a mechanism to clean these up on
web app shutdown that is just about OK but that could would need to be
carefully coded.

Re: Tomcat dies suddenly

2010-02-02 Thread Carl


Chris,

There appears to be some bling that openSuse has that Slackware doesn't but 
otherwise they seem to be the same.  I tried openSuse because 1) Dell stated 
they had tested their servers with that distribution and 2) Sun stated that 
the Java distribution had been tested using openSuse.  My thought was there 
might be a subtle difference that could either explain what I was seeing or 
give me a clue to what was happening.  No luck with either.


However, I have found a couple of things that might account for the 
failures:


1.  Slackware, by default, installs a version of Java (1.6.0_16.)  I knew 
this but apparently neglected to remove it using the package manager (I 
noticed it was still installed because nepomuk was starting a java process 
which was showing up in VisualJVM.)  So, there were two versions of Java 
running, one from /usr/bin/java and one from /usr/local/java.  Don't 
remember what JAVA_HOME was set to and not certain how Tomcat actually 
started but both JAVA_HOME and PATH are correct now.


2.  One of the servers had no swap.  Should not have been a problem since I 
don't recall ever getting to the maximum physical memory (4GB) on that 
machine.  However, I suspect if the system ever hit the physical memory 
limit, we could well see the OOM killer.


I did restrict the heap (yesterday) to 500MB and the garbage collection was 
hit frequently and performed properly so it seems my hypothesis that it 
might be the GC process is false.


So, the monitoring continues.

Thanks,

Carl

Is there an appreciable difference between OpenSUSE and Slackware in
your environment? They may be on slightly different kernel patch levels,
or glibc levels, etc. but it always boils down to the Linux kernel and
GNU libc.

Hello,

Your threadLocal variable is created by the reflectionToString feature
of Jakarta Commons Lang ToStringBuilder (1).

This thread local variable seems to be used to prevent infinite
recursion when ToStringBuilder traverse the objects.

I didn't see yet a way (servlet filter, etc) to cleanup this ThreadLocal.

Hi All:

I am getting the following error when I deploy a sinple service version to

Could not send command message ContextClusteringCommandCollection to group

Re: How to do error page forwarding...


 1) - Is Tomcats handling of an error page defined in web.xml broken
 when a response has already been committed?
 Inconsistent? Yes. Broken? Maybe.

 2) - Is there anything I can do to force the browser to a proper error
 page after a response has been committed?
 No. Adding the error page to the end of the content is the best you can
 do but that is still a very fragile solution.

 Mark


Thanks.

I'll note the inconsistency in the bug tracker, in case someone feels
like fixing it.

You don't mess with the classpath directly.
You add the jar to your web application lib directory.

 myapp/WEB-INF/lib

or, you add it to one of Tomcat's lib directories.

 tomcat/server/lib
 tomcat/common/lib
 tomcat/shared/lib

depending on what the jar contains and is supposed to do.

If you're asking this type of question, you probably need to read the

Re: Tomcat dies suddenly

Carl,

Maybe I missed it, but you still haven't clarified what you mean by
tomcat stops.

Does Tomcat do an orderly shutdown?
Does Tomcat appear to freeze (stop answering new requests)
Does the JVM hosting Tomcat crash?

Assuming you have a JVM crash issue here... you should try other JVMs
(32 bit, and/or other versions).
You should try different JVM switches.
And you should find the JVM crash log file - you should have one somewhere.

You can use these options on your JVM in your tomcat start sequence to
control where the JVM crash log will be written (And to force one for
an out of memory error)

-XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/logFolder

Re: Tomcat 100% CPU usage after moving from Java 5 to 6


 Well, as I said, Tomcat is working much more stable now than it did before.
 However, once in a few days it still becomes unresponsive, while CPU usage
 stays incredibly low.

Unresponsive, meaning what, exactly?  If the CPU is idle, but your
webapp isn't returning a response... it seems to indicate that your
webapp is waiting on something else... DB query, file read, whatever.
It seems unlikely that it would be blocked, consistently by a garbage
collection - especially with the heap sizes you are running with.

VisualJVM can give you a clue as to what threads are running, and
which ones are waiting when the system is unresponsive.

Active DataSource Connection count never decreasing with PostgreSQL

I have developed an application which accesses a database via Hibernate as well 
as directly via JDBC (datasource). The datasource is defined in the server.xml 
file as follows:

Context path= docBase=AddressBookServer.war 

  Environment name=LicenseFile value=Licensekey.license 
type=java.lang.String override=true/ 
  Environment name=BackupsFolder value=../backups 
type=java.lang.String override=true/   
 
  Resource name=jdbc/AddressBookDB auth=Container 
type=javax.sql.DataSource
 maxActive=25 maxIdle=5 maxWait=-1 removeAbandoned=true 
removeAbandonedTimeout=60 logAbandoned=true
 username=sa password= driverClassName=org.h2.Driver
 
url=jdbc:h2:tcp://localhost:28081/../db/AddressBookDB;LOCK_TIMEOUT=6/

  Realm className=org.apache.catalina.realm.JDBCRealm
driverName=org.h2.Driver

connectionURL=jdbc:h2:tcp://localhost:28081/../db/AddressBookDB;LOCK_TIMEOUT=6
connectionName=sa connectionPassword=
userTable=WEBUSERS userNameCol=USERID userCredCol=PASSWORD
userRoleTable=WEBROLES roleNameCol=ACCESSROLE/

/Context

By default I use an embedded H2 database and everything works great. The 
numActive count goes up during activity and decreases to 0 when there is no 
activity. Also the count generally matches the actual connections to the 
database as one would expect. If I use the same application with PostgreSQL 8.4 
however, the numActive count goes up and up, and only sometimes down. Generally 
sitting around 25 even though PostgreSQL only reports 4 idle connection. 

I already tried adding the following to my datasource configuration, however 
this did not make any difference so far.
removeAbandoned=true removeAbandonedTimeout=60 logAbandoned=true

I am using Tomcat 6.0.18 on OS X 10.6.2 with Java 1.6.

Any suggestion on how I can debug this further why Tomcat reports an incorrect 
numActive count and eventually runs out of possible connections. Currently it 
has to be restarted several times a day with PostgreSQL.

Thanks in advance
Alex

It works fine with the 32 bit version of the isapi_redirect.dll.   The problem 
I was having was that I was making the registry changes to the wrong location 
for a 64 bit OS.

32 bit OS registry location:
[HKEY_LOCAL_MACHINE\SOFTWARE\Apache Software Foundation\Jakarta Isapi 
Redirector\1.0]

64 bit OS registry location must be here:
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Apache Software Foundation\Jakarta 
Isapi Redirector\1.0]

The difference is this Wow6432Node.

OR save yourself some time and use the isapi_redirect.properties file instead 
of changing the registry.

That's 221760 minutes, and you only have two GC log lines near or after
that time:

It's interesting that there's no timing data for that last statement. It
/is/ possible this is where the JVM went down. (Did it go down?)

Both of these GC runs seem to be collecting a /lot/ of garbage:

3272635K-747297K

That's a reduction of roughly 75%... though I guess in .13 seconds, it's
not taking so long, so it should be fine. I guess your webapp generates
a lot of temporary data, fast. At least it gets cleaned-up quickly.

 Also, what happens if you remove all your *GC* options (other than
 logging) from your JAVA_OPTS?
 
 I am quite hesitant to try this. This is a production environment, and all
 in all Tomcat is performing pretty good now, in comparison to what the
 situation was before.

Do you have a place where you can really play around with this?

 By all GC options, do you also mean the UseConcMarkSweepGC? Wouldn't the
 GC become serial then (with pauses which stop the whole webapp for a while)?

I don't believe the GC will do serial collections unless explicitly
told to do that. The days of stop the world garbage collection are
long gone.

 And also the +DisableExplicitGC?

That only causes the JVM to ignore calls to System.gc(), which aren't
guaranteed to do anything, anyway. Unless you are deploying unknown
webapps, this probably isn't doing anything at all.

 Is this reproducible?
 
 Well, as I said, Tomcat is working much more stable now than it did before.
 However, once in a few days it still becomes unresponsive, while CPU usage
 stays incredibly low. I have tried load tests using jMeter on our
 development environment, but it's working fine then. Must have something to
 do with the real (more diverse, less predictable/repetitive) traffic on
 the production environment, I guess..

I'd be interested in what a thread dump shows you during one of these
pauses. I agree with Dan: this sounds much more like your webapp is
waiting around for something like a db connection than doing anything
active. If the GC were running like crazy, I suspect you'd see more CPU
usage.

Can't Disable Apache Tomcat

2010-02-02 Thread A. Wolf


Tomcat is set to disabled on my Vista machine.  But it still appears in the
taskbar and in task manager.  How do I prevent it from loading entirely at
startup?  I've looked under Admin Tools -- Services, but it's listed as
Disabled there.

This is really bothering me.  I'm about ready to uninstall all Apache
services from my machine, as I rarely use Apache and I don't want it to load
into RAM at startup.  Any help on removing it from RAM, apart from selecting
Exit every time I start my machine, would be greatly appreciated.

Still unable to get a heap dump from Tomcat running on Windows as a service

I am still unable to get Tomcat to dump heap when it encounters an
OutOfMemoryError.  My StackOverflow topic sums up what I've tried so far:
http://stackoverflow.com/questions/2172220/can-i-get-tomcat-running-as-a-service-to-dump-heap

I'm using the graphical program that comes up when you select Monitor
Tomcat from the Windows Start Menu.  I assume this is TomcatW.exe?

I have Tomcat 6.0.20 running as a service under the default local user
account, set to be allowed to interact with the desktop (I don't know if
this is necessary; I've tried it both ways with no effect on the outcome).

I've attempted to switch the startup mode to java from jvm to see if
that would make a difference, but in that case the service simply won't
start.

I've specified -XX:HeapDumpPath=C:\crap, and -XX:HeapDumpPath=C:/crap to no
avail.  C:\crap is world readable and writable.

I've set the working path for the Startup and Shutdown tabs to C:\crap and
C:/crap with no effect.

I've set memory to a minimum of 512 and a maximum of 1024 MB.

Finally, following the example of what was already there in the text box, I
entered the JVM options one per line.  The tomcat documentation says to
enter them separated by either a # or a ;, but I suspect that the GUI
tool may be taking them and turning line breaks into # characters for me.

Does anyone have any other suggestions to try before giving up on Tomcat in
favor of either Jetty or (God help me) JBoss?

Thanks much,
Laird

Re: Can't Disable Apache Tomcat

2010-02-02 Thread Len Popp

What exactly is it that appears in the Task Manager? Is it
tomcat6.exe? Or tomcat6w.exe? Or java.exe?

tomcat6.exe is the Tomcat service.

tomcat6w.exe is the Monitor Tomcat program. It is not Tomcat, it is
a separate small program for managing the Tomcat service.

Tomcat 6.0 Manager role not working on RHEL 5.4

2010-02-02 Thread Ajay Tomar

Hi,
  I installed tomcat 6 on RHEL 5.4 and would like to get access to
manager app. But I am not able to get it work even after modifying
tomcat-users.xml.. Here is the output --- tomcat-users

I stopped and started tomcat... Any ideas what may be missing here.. I
can access localhost:8080 and see tomcat is running.. I am able to run
sample servlets and jsp

Thanks in advance..

Looks like your manager and user entries are still within the

something much more obscure.

RE: Still unable to get a heap dump from Tomcat running on Windows as a service

 From: Laird Nelson [mailto:ljnel...@gmail.com]
 Subject: Still unable to get a heap dump from Tomcat running on Windows
 as a service

 I am still unable to get Tomcat to dump heap when it encounters an
 OutOfMemoryError.

You appear to be unique in that regard, since no one else seems to be having 
that problem.

 I'm using the graphical program that comes up when you select Monitor
 Tomcat from the Windows Start Menu.  I assume this is TomcatW.exe?

Not quite; it's tomcat6w.exe (note the digit and no caps).

 I have Tomcat 6.0.20 running as a service under the default 
 local user account

What's a default local user account?  Try using a real account, possibly one 
in the administrators group to see if that makes a difference.

 set to be allowed to interact with the desktop

Not needed.

 I've specified -XX:HeapDumpPath=C:\crap, and -XX:HeapDumpPath=C:/crap
 to no avail.

Try just leaving that parameter out.

 I've set the working path for the Startup and Shutdown tabs
 to C:\crap and C:/crap with no effect.

The Shutdown working path doesn't matter, since that's not normally used.  Try 
setting the Startup path to the Tomcat installation directory after 
reinstalling Tomcat.  The direction of the slash doesn't seem to matter; I get 
the .hprof file generated in the designated directory regardless of which I use.

 I've set memory to a minimum of 512 and a maximum of 1024 MB.

You normally want those to be the same for a server environment to avoid heap 
thrashing.

 I entered the JVM options one per line.

That is a requirement.

 The tomcat documentation says to enter them separated by either 
 a # or a ;

That's for command-line usage, not the GUI.

 Does anyone have any other suggestions to try before giving up on
 Tomcat in favor of either Jetty or (God help me) JBoss?

Sounds like a baby with the bathwater solution...

I would try removing the existing Tomcat service, reinstalling the current 
(6.0.24) Tomcat from the .zip download, using the service.bat script to create 
the service, and only then try recreating the OOM problem.  Unpack the .zip 
download into someplace other than C:\Program Files.  Also try setting the 
Level on the Logging tab to Debug rather than Error to see if that shows 
anything interesting.

 I removed a file and a directory named WebApplication2, and that

It's fully documented:

Context elements may be explicitly defined:
...
* In individual files (with a .xml extension) in the 
$CATALINA_BASE/conf/[enginename]/[hostname]/ directory. The name of the file 
(less the .xml extension) will be used as the context path. Multi-level context 
paths may be defined using #, e.g. foo#bar.xml for a context path of /foo/bar. 
The default web application may be defined by using a file called ROOT.xml.
* Only if a context file does not exist for the application in the 
$CATALINA_BASE/conf/[enginename]/[hostname]/, in an individual file at 
/META-INF/context.xml inside the application files. If the web application is 
packaged as a WAR then /META-INF/context.xml will be copied to 
$CATALINA_BASE/conf/[enginename]/[hostname]/ and renamed to match the 
application's context path. Once this file exists, it will not be replaced if a 
new WAR with a newer /META-INF/context.xml is placed in the host's appBase.

RE: Can't Disable Apache Tomcat

 Tomcat is set to disabled on my Vista machine.

That's the Tomcat service, not the GUI interface.

 But it still appears in the taskbar and in task manager.

That's the GUI management tool.

 How do I prevent it from loading entirely at startup?

Somewhere, you've got a registry entry or startup script referring to 
tomcat?w.exe //MS// (where the ? is Tomcat base level - which you didn't tell 
us).  Delete the registry entry or startup script.

 This is really bothering me.

Why?

 I rarely use Apache and I don't want it to load into RAM 
 at startup.

Perhaps you're confusing Windows with DOS - we have virtual memory now, so 
anything that's not being used pages out to disk rather quickly if the real 
memory space is needed.

Not sure it's promoted; I think it's mostly there for the casual Windows

RE: Still unable to get a heap dump from Tomcat running on Windows as a service

 From: Laird Nelson [mailto:ljnel...@gmail.com]
 Subject: Re: Still unable to get a heap dump from Tomcat running on
 Windows as a service

 I'm not a Windows guy, so bear with me for a moment:

I'm not sure there's anyone who really understands Windows security.

 Or is there some other privilege setting that says even if there's
 permission granted to the filesystem, the system account shalt not
 write even unto it?

Windows security settings are truly bizarre, and the Local System Account is 
subject to restrictions that don't seem to make any sense.  It certainly *can* 
write some files, otherwise Tomcat wouldn't be able to function at all.  BTW, 
on Vista, you can't seem to change the account the Tomcat service runs under 
with the GUI tool - it has to be done with the Administrative Tools - Services 
snapin; don't know if that's true for Server 2K3.

I just tried forcing an OOME dump with Tomcat running under the Local System 
Account - and it worked.  This is under Vista 64, not Server 2K3, and starting 
with the .zip download.

You could always try downloading and installing the .zip version in an 
alternate location, and install the service under an alternate name just for 
testing.  I don't have access to a Server 2K3 system to play with.

Nope, but I'm not an expert with these (at all).

I use something pretty similar, the only real difference is that I
haven't turned on the CMSIncrementalMode.  My apps haven't shown an

Consider using DataSourceRealm instead of JDBCRealm: JDBCRealm uses a
single Connection object (thereby serializing logins) and has had a
bunch of concurrency issues in the past. DataSourceRealm can use your
previously-configured DataSource for Connections. Or, you can define an
authentication-only DataSource that is used only by the DataSourceRealm.

By default I use an embedded H2 database and everything works great.
The numActive count goes up during activity and decreases to 0 when
there is no activity. Also the count generally matches the actual
connections to the database as one would expect. If I use the same
application with PostgreSQL 8.4 however, the numActive count goes up and
up, and only sometimes down. Generally sitting around 25 even though
PostgreSQL only reports 4 idle connection.

I already tried adding the following to my datasource configuration,
however this did not make any difference so far.
removeAbandoned=true removeAbandonedTimeout=60
logAbandoned=true

Did you look at your log files after setting these parameters?

I am using Tomcat 6.0.18 on OS X 10.6.2 with Java 1.6.

Any suggestion on how I can debug this further why Tomcat reports an
incorrect numActive count and eventually runs out of possible
connections. Currently it has to be restarted several times a day with
PostgreSQL.

While there are other possibilities, you might want to read this:
http://blog.christopherschultz.net/index.php/2009/03/16/properly-handling-pooled-jdbc-connections/

I would /highly/ recommend running with maxActive=1 in all
environments except for production, as you will likely trigger any
Connection leaks much more quickly that way.

 From: Richard Sickler [mailto:richard.sick...@avagotech.com]
 Subject: Re: Problem on Tomcat 6.0.20

 I removed a file and a directory named WebApplication2, and that
 cleared up that problem.  On to the next undocumented feature!

 It's fully documented:

 Context elements may be explicitly defined:
 ...
    * ... If the web application is packaged as a WAR then 
 /META-INF/context.xml will be copied to 
 $CATALINA_BASE/conf/[enginename]/[hostname]/ and renamed to match the 
 application's context path. Once this file exists, it will not be replaced if 
 a new WAR with a newer /META-INF/context.xml is placed in the host's appBase.

Documented, yes.  Astonishingly silly and surprising behaviour?  Also yes.

Good luck getting them to improve it.
https://issues.apache.org/bugzilla/show_bug.cgi?id=45979
https://issues.apache.org/bugzilla/show_bug.cgi?id=32284

Near as I can tell, this surprising and bizarre behaviour occurs
because Remy likes it that way.

In my opinion, Tomcat should remember if it copied the file out of a
war file... and if the war file is replaced, it should overwrite the
file with the new file from the new war file.

Is it trivial?  Not exactly, Tomcat would have to somehow keep track
of if the file was manually modified or not... but really, it just
needs to keep a hash of the file somewhere so it can check if the file
has been changed since it put it there.

I think Tomcat should also log a warning message when it doesn't copy
a context.xml from a war file... because the developer has made a
mistake at this point - someone manually changed one version, but
didn't change the one in the war file.

The current design leads to people having problems like you have -
because beginning developers aren't (and really) shouldn't have to be
aware of this nasty gotcha of Tomcat.

The Local System account is the usual local built-in account used to 
run Services. It has quite extensive privileges on the local machine 
(like the permission to run Services), but has no access to Windows 
network resources.  That includes stuff like network shares, network 
printers etc..
It can however run programs that open TCP/IP sockets to/from anywhere. 
Go figure.


The suggestion of Chuck to run Tomcat as an Administrator is, I believe, 
just a temporary measure to verify if the fact that you are not getting 
the logfiles you expect, would be due to a permission problem to some 
local directory. It would be nice to eliminate that possible source of 
trouble.



Later on, you can revert to LocalSystem, or to some other user, local or 
domain-based.  Which one you choose is a matter of your in-house 
policies, or which resources the apps running in Tomcat will need to 
access later.
Just make sure that while you are running as Administrator, your Tomcat 
does not inadvertently create some files to which later, when it runs as 
another user again, it would not be able to write anymore.




While we are at it, the difference between the .exe version, and the 
.zip version :


The .exe version is like a shortcut, for people used to Windows 
installer programs and who just want to install and run Tomcat as a 
Windows Service, with a gui program (tomcat?w.exe) to set the run 
parameters in the Registry.  With that version, you cannot run Tomcat in 
a command-line window for instance.


The .zip version is more similar to the way you install Tomcat under 
Unix/Linux : you get a bunch of additional scripts and files in the 
tomcat/bin directory, which allow you to run Tomcat in a command-line 
window, which sometimes makes it easier to debug a problem.
It also contains scripts to install and configure Tomcat as a Windows 
Service, but they are a bit more command-line oriented rather than 
graphical.


The real pros tend to prefer the .zip.
;-)

It's the same Tomcat in both cases however.

LocalSystem can impersonate any user on the computer, but has no
rights over the network.  It's actually a very highly privileged
account - if an application running as LocalSystem wanted to, it could
impersonate the local Administrator account without requiring a
password.  There are a few niceties about what that impersonated
Administrator account could do... but not many.

If you doubt this, note that IIS runs as LocalSystem and uses
impersonation to handle integrated login - it just sets the thread
handling the request to the required identity before handling the
request, and sets it back afterwards ;-).

 I believe you can also download resource kit from Microsoft that has tools
 that lets you watch all objects opened by a process ( so, look if Tomcat is
 even trying to open the file ). Its been a while, so don't recall tool
 sytax.

Process Explorer (

I am still unable to get Tomcat to dump heap when it encounters an
OutOfMemoryError.

You appear to be unique in that regard, since no one else seems to be having 
that problem.

I'm using the graphical program that comes up when you select Monitor
Tomcat from the Windows Start Menu.  I assume this is TomcatW.exe?

Not quite; it's tomcat6w.exe (note the digit and no caps).

I have Tomcat 6.0.20 running as a service under the default
local user account

What's a default local user account?  Try using a real account, possibly one 
in the administrators group to see if that makes a difference.

set to be allowed to interact with the desktop

Not needed.

I've specified -XX:HeapDumpPath=C:\crap, and -XX:HeapDumpPath=C:/crap
to no avail.

Try just leaving that parameter out.

I've set the working path for the Startup and Shutdown tabs
to C:\crap and C:/crap with no effect.

The Shutdown working path doesn't matter, since that's not normally used.  Try 
setting the Startup path to the Tomcat installation directory after 
reinstalling Tomcat.  The direction of the slash doesn't seem to matter; I get 
the .hprof file generated in the designated directory regardless of which I use.

I've set memory to a minimum of 512 and a maximum of 1024 MB.

You normally want those to be the same for a server environment to avoid heap 
thrashing.

I entered the JVM options one per line.

That is a requirement.

The tomcat documentation says to enter them separated by either
a # or a ;

That's for command-line usage, not the GUI.

Does anyone have any other suggestions to try before giving up on
Tomcat in favor of either Jetty or (God help me) JBoss?

Sounds like a baby with the bathwater solution...

I would try removing the existing Tomcat service, reinstalling the current 
(6.0.24) Tomcat from the .zip download, using the service.bat script to create 
the service, and only then try recreating the OOM problem.  Unpack the .zip 
download into someplace other than C:\Program Files.  Also try setting the 
Level on the Logging tab to Debug rather than Error to see if that shows 
anything interesting.

Re: Active DataSource Connection count never decreasing with PostgreSQL

The URL is interpreted by the JDBC driver / database. If you take a look at the 
database documentation even tilde ~ is suggested. Otherwise the database is 
relative to the working directory

http://www.h2database.com/html/cheatSheet.html

However this has got nothing to do with my issue which is only apparent on 
postgresql and now H2.

I had a look at the article you posted a link to. I am using JSTL SQL 
statements which use the datasource and otherwise an hibernate entitymanager. I 
guess it could be that I missed an entityManager.close somewhere, yet I do 
apply the same close handling with try catch finally suggested by your article. 
I was hoping that the logAbandoned flag would produce any warnings, however so 
far I have not seen anything. It's also strange that this is only apparent on 
PostgreSQL and not H2. It could well be that H2 is more forgiving to unclosed 
connections though.

Thanks again for all your suggestions.

 Put this into either META-INF/context.xml within your WAR/webapp
 directory, or into CATALINA_BASE/Catalina/[hostname]/ROOT.xml
 
 Remove the path and docBase attributes when you move the
 Context element.
 
 I really like it that way as it allows me to configure what I need to
 in one central place without having to touch or expand the WAR file.
 
 And it breaks things.  You are now getting double deployment, once under the 
 name AddressBookServer and once again as ROOT.  Do it the right way, by 
 renaming your .war file to ROOT.war, and placing the Context element in 
 conf/Catalina/[host]/ROOT.xml - that also avoids having to change the 
 contents of the .war file.  (Note that Chris' suggesting was missing part of 
 the path.)  As Chris said, when you do that, remove the path and docBase 
 attributes.
 
 This also works great for me. My database folder is relative the the
 startup script.
 
 That's really asking for trouble.  A parser has complete freedom to ignore 
 any .. entry in a URL, so if it happens to be working now, you're extremely 
 lucky, and there's no guarantee it will work tomorrow.  The URL is *not* 
 relative to any current directory, since it doesn't target the file system 
 per se.

Re: Still unable to get a heap dump from Tomcat running on Windows as a service

Thanks for sticking with me, guys.  No luck so far.  I will begin the
laborious process of requesting a reinstall.  :-(

(Incidentally, no service logs either, anywhere; this is all very bizarre.)

  set the HeapDumpPath option, so you can actually write to a
  location on disk

 You're late to the party; that's already been tried, to no effect.  It's
 not needed if the Startup tab has the Working Path set - which Laird has
 also tried.  Seems to work for everyone but him.

 Subject: Re: Problem on Tomcat 6.0.20

 I removed a file and a directory named WebApplication2, and that
 cleared up that problem.  On to the next undocumented feature!

 It's fully documented:

 Context elements may be explicitly defined:
 ...
* ... If the web application is packaged as a WAR then 
 /META-INF/context.xml will be copied to 
 $CATALINA_BASE/conf/[enginename]/[hostname]/ and renamed to match the 
 application's context path. Once this file exists, it will not be replaced 
 if a new WAR with a newer /META-INF/context.xml is placed in the host's 
 appBase.

 Documented, yes.  Astonishingly silly and surprising behaviour?  Also yes.

 Good luck getting them to improve it.
 https://issues.apache.org/bugzilla/show_bug.cgi?id=45979
 https://issues.apache.org/bugzilla/show_bug.cgi?id=32284

 Near as I can tell, this surprising and bizarre behaviour occurs
 because Remy likes it that way.

 In my opinion, Tomcat should remember if it copied the file out of a
 war file... and if the war file is replaced, it should overwrite the
 file with the new file from the new war file.

There are two opposing opinions on what is the correct behaviour here.
That is one, the other is that if I want to edit the context.xml Tomcat
should a) make this easy so I don't have to muck about with the WAR and
b) not overwrite my changes.

 Is it trivial?  Not exactly, Tomcat would have to somehow keep track
 of if the file was manually modified or not... but really, it just
 needs to keep a hash of the file somewhere so it can check if the file
 has been changed since it put it there.

The simpler solution is just not to expand it. Tomcat doesn't need to
expand it to read it.

 I think Tomcat should also log a warning message when it doesn't copy
 a context.xml from a war file... because the developer has made a
 mistake at this point - someone manually changed one version, but
 didn't change the one in the war file.

That is a good idea for an enhancement. As ever, patches welcome.

 The current design leads to people having problems like you have -
 because beginning developers aren't (and really) shouldn't have to be
 aware of this nasty gotcha of Tomcat.

And overwriting an edited context.xml has similar gotchas.

One idea I have seen proposed in the past is to make the extraction of
context.xml configurable per host. That should be fairly simple. Again,
patches welcome.

I've added https://issues.apache.org/bugzilla/show_bug.cgi?id=48662 to
track these ideas. Feel free to add to that.

 ¿does somebody knows what I have to do to change trace level of
 jakarta_service_date.log  and stdout_date.log from 'info' to 'warn'?

 jakarta_service_date.log :

Start  All Programs  Apache Tomcat 6.0  Configure Tomcat

then switch to the Logging page and choose Level, one of: Error,
Info, Warning, Debug.

 stdout_date.log:

java.util.logging.ConsoleHandler.level = WARNING
(in conf\logging.properties)

See java.util.logging log level names here:

This will definitely help :
http://www.ioplex.com/
Look for Jespa
It is free up to a number of users, and very reasonably priced after 
that.  It works perfectly, and is very easy to set up.


Otherwise, as someone else suggested and if you are using an Apache 
httpd front-end, you can also use an Apache httpd-based authentication, 
and pass the resulting user-id to Tomcat.
In a pure Windows environment, it should be possible to do soething 
similar with IIS as a front-end.
