I agree, largely - it's long been an ambition of mine to improve things,
but I haven't been able to make much progress yet.  Was a bit more
complicated than I thought it would be when I started experimenting.

This sounds increasingly like your application isn't returning
connections to the pool properly.  Switching pool implementation won't
help if this is the case.

You should carefully examine the code where the database is used to
ensure that DB resources are returned to the pool in a finally block,
after use.

Chris's question regarding 'what has changed' is still relevant.

Please tell us exactly which version of Tomcat (and anything else that's
relevant, e.g. HTTPD), or we may incorrectly assume the wrong one.
There are now 25 versions of Tomcat 7.0.

The browser throws an exception or Tomcat does?

Where is the XSL file and which part of the system needs to access it?
For example, is Tomcat rendering the output or is the browser rendering it?

I don't understand, what does "and this request used to be POST" mean then?

The login form defines the method used to send the request, the browser
sends it, not Tomcat.

When Tomcat receives an unauthenticated request for a protected resource
it intercepts and saves that request, then forwards to the resource
defined in the login config.

If the login form action is successful, the previous request is restored
and executed.  So I asked if the request is not being restored properly...

So either you're telling us that there's a bug in Tomcat, or you're
telling us something else and I don't know what that is.

Can you reproduce the error using a clean & simple application config?

I work for a fairly large & well known company that ships a commercial
version of Tomcat with the default heap size set to 512Mb.

I regularly see heaps of 2Gb and more at work with customers.

Quibbling about memory size because the number 'seems a bit large' is a
waste of your customer and your own time.  If they're not paying for you
for the time you take to explain, just tell them it's normal & move on.

So, you're saying that the method value 'POST' is not preserved after
successful authentication and appears to be converted to a 'GET'?

And of this, a Tomcat instance with just the ROOT application can be
observed to consume from ~6Mb to ~10Mb of RAM in the object heap with
a nice stable sawtooth on most systems.

VisualVM connected to Tomcat will provide you with a nice graph
demonstrating this, which you can compare to a graph from the
customers application.

In single threaded startup mode, the process uses 2 cores?

You refer to system and host separately, is it virtualised?

You should not send the same message twice, using different emails
addresses, for a start.

Reading the following guide will help you understand how to ask
questions on technical mailing lists and get the solution to your

So, just to confirm, did you stop this Tomcat instance and then generate
the thread dump?

I ask because all of the application threads are daemon threads and
don't appear to be blocked...

That's great - and thanks for letting us know.

If you have time, I think it would be interesting to know your
application sizes, individual startup time and how many
startStopThreads you are using.

The maxThreads in the Connector only applies to Tomcat request
processing threads, it is not a limit imposed on the whole JVM.

You will usually have 20-30 threads running doing various things in
addition to those that your app starts.

If Tomcat is at 500 + 20 then the rest are likely to be started by your
application or dependencies.  As Dan states, a thread dump is the way to
understand this.

No, it's not.

If you want to build a multi-tenant application, you should:

1. Make your application the ROOT application.
2. Then use the first part of the path to determine which tenant.
3. Use the path data to select a configuration as required.

What is the benefit in making it one application?

(Please don't top post.)

It's worth noting that some browsers appear to cache certs and sometimes
changes are not immediately apparent.

So Spring 3.1 is now out and the internetz says that Spring 1.2.8 was
released 8 May 2006.  Is this a production system, might I ask?

There are 35 versions of Tomcat 6.0.
I will assume that you are using Tomcat 6.0.3.

Upgrade! Upgrade! Upgrade!

So stop the process that is using port 8009, OR change the port 8009
value on the AJP connector in server.xml.

If you are not actually using AJP to connect an HTTPD instance to
Tomcat, then you can just comment it out.

Yes, it certainly looks like one, but as I asked you to remove the XML
comments and you haven't, I can't be bothered to read any further.

Please reply below the question, not at the top of the email.
Top-posting makes the conversation really hard to follow.

If you are saying that you *have* changed the port and the problem still
persists, you might want to consider stopping Tomcat before you try to
start a new version with the same configuration.

If you have tried to stop Tomcat, and it is still running, you probably
have a bug in your application.

We can't help you unless you provide the following:

- Exact versions of OS, Java and Tomcat.
- Error messages from Tomcat log files
- Cut & paste server.xml into your reply AFTER removing all XML comments
and sensitive information like passwords & ip addresses

The system is using swap.  What else is running on the system?

The top output should also be able to tell you how much memory Tomcat is
consuming.


> I see there is 8 Gb swap unused, so Tomcat does not bother claiming it.

That is not clear from the above.

The JConsole and VisualVM applications provided with the JDK will tell
you how much memory is being consumed by the application in various
areas of the Java program's process heap.

You may use them to observe behaviour during the operation you are
experimenting with.

There are a number of log files in the 'logs' directory of your Tomcat
installation.  Have a look in each file for additional information and
report back.

What is changing the log level and where is the code doing it located,

Probably not.  Have you looked at the JMX MBeans for JUL?

Are you expecting the timeout to fire at this point, for those requests?

The request seems to think it is in the "DISPATCHING" state - is this
perhaps a long running stream of events?

Did you mean to send two copies of this email?

Have you read the relevant sections of the appropriate version of the
Servlet Spec?  (You didn't say which version of Tomcat, so I'll guess
6.0.x) See: SRV.3.7

You may also benefit from reading:

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

and

The Common Name must match the domain name of the server as seen by the client.

You would need to purchase a different one to comply with the terms of

So what Mark & are both saying is this: in the JSP there is some code
which imports, via a wildcard, two packages that both contains a Part class.

We are not talking about importing things on the file system.  We are
talking about a specific Java command which is part of the code.  E.g.

If both of the packages below contain a class called "Part", then the
compiler can't tell which one you are trying to use.

 import com.examples.stuff.*
 import com.examples.other.*


You can use an editor to look in the the JSP file in question for the
word "import" somewhere near the top of the file and the '*' character.

If there is more than one '*', you can report the error to Serena
Dimensions or try to fix it yourself.

The error message says you have a bug in the JSP.

The bug appears to be that the "Part.class" reference is ambiguous.

This means that more than one Part.class reference is visible in the
scope of the JSP, possibly via an import statement inside the JSP.

Can you examine the JSP code?

Session counts are per-application.
You can connect via a (secure) JMX connection and extract this
information to do whatever you want with it.

Yes, but I would limit access to known IPs using the RemoteIpValve.

... and that URL is unlikely to work anyway, unless you've got a really
broken Tomcat.  (It's missing a 'lib' directory in the path.)

It's can be tricky and it's application specific.

You'll need to add specific policy rules that permit the application to
do whatever it needs to do.  E.g. access to network, file system, jars etc.

Is there a particular reason you want to enable the Security Manager?
Are you hosting untrusted 3rd party applications for example?

So does org.apache.catalina.connector.ResponseFacade.

When you do Response.getResponse() you get a ResponseFacade, just like
an application does, with a different implementation.

So call that one instead.

 Reproducible on Tomcat 6.35.

 To reproduce this, you may use the attached test materials:

Queue of what?  Tomcat doesn't have any queues.  Queuing is usually
associated with messaging products or applications.

Sounds like an application problem.  A messaging application problem.

You are referring to the Connector.  The Connector processes requests.
You could extend it yourself to do whatever you wanted, but you are
probably just better creating a separate instance for each tenant and
starting it in its own JVM.

See RUNNING.txt for details of how to separate CATALINA_HOME and
CATALINA_BASE so you can use a common runtime for multiple instances.

Endorsed is for overriding classes supplied in the JDK.

 http://docs.oracle.com/javase/6/docs/technotes/guides/standards/

If you want to share JARs (why do you want to do that?) between webapps
in Tomcat 6.0.x you just need to put them in tomcat/lib.

What does "update a couple of jar files" refer to?  Tomcat or InetSoft?

Does this procedure also involve updating Tomcat and if so, how did you
do that?

You didn't actually say, but I assume from the error that you are using
Windows.  Did you check the Tomcat log files and find any errors there?

1. Don't top-post.
2. Don't hijack threads.
3. If you're going to reply to a thread, at least read it beforehand.
4. Particularly this: http://catb.org/~esr/faqs/smart-questions.html

You can replace the contents of XML attributes in server.xml with variables.

 

The variables are taken from conf/catalina.properties which is a Java
Properties file.

You could programmatically update that file and then restart the Tomcat
instance.  You will need to restart the Tomcat instance if 'talks to an
LDAP server' refers to a Realm or DataSource defined in server.xml.

I will assume you have read the RUNNING.txt file in your distribution.

These are the relevant documentation pages:

You can use an executor to provide a common thread pool for all linked
connectors - to reduce the overhead of unused threads.

keystoreType has the default, you can remove it.
I don't like the look of those paths, this is neater:

 keystoreFile="${catalina.base}\conf\wcmdev-ssl.jks"

 truststoreType has the default, you can remove it.

sslProtocol is also the default, you can remove it.

Are you actually using the AJP connector?

Can you remove all of the client auth config and just configure the
keystore alone, first to try to get the SSL working?

Did you follow the steps here?

Right now & for me: hard, because I'm using an iPhone.

Tomorrow easier: but having a minimal test case for reproducing the

There are now 3 threads with non-obvious issues referencing 7.0.23. I
don't yet see any common ground.

Following them all and comparing notes isn't unreasonable.

Are you having an issue with Netbeans rather than with Tomcat?  If so,
you may find more help with that community.

There is no Servlet API for this.

It might be possible to access the web.xml file (on the file system or
by JMX) and reparse it, but I would be cautious about doing this myself.

Seems like a lot of work for very little return.

Can you make a minimal test that reproduces the problem?

Is it reproducible with Tomcat's own Comet support?

When did the problem start occurring and what else has changed?

Can you stop monitoring with Munin and see if the problem goes away?
If it does, I would consider that Munin may not be properly closing the
connections it makes.

Can you please remove the XML comments and obscure username/password/ip

Yes and no.

It is not possible to split web.xml into separate parts and subsequently
merge them.

It is possible (in Servlet 3.0) to create web-fragment.xml files with
distinct application components.  Read the Servlet Spec to understand more.


The server.xml file is parsed separately and can use XML entities, and
can therefore include external files.


> The web.xml file & server.xml is getting large and I want it to be more

Most people just put up with a verbose web.xml file.

Why is server.xml getting so big?  Have you removed all of the XML comments?

Are you using RMI for anything in your application or is this a

Are you using JMX for something specific?

Is this exactly as you have it, or is it a typo?

If it is accurate it is a thoroughly broken configuration and will
mean that every directory in there is deployed as an application.

FarmWarDeployer doesn't do that.
It is a push mechanism rather than a repository of applications queued

How on earth are you supposed to meet all of these requirements?

If you want to have a sane security scheme then you will have to make
it clear to your client that all things are not possible at the same
time and they will have to choose from a list of compromises.

Right now you are up against limitations that you are imposing on
yourself. We can't fix that.

If you can't simplify the requirement then you will need a more
complex security layer. You can either write this yourself, or use an
existing component like Spring Security*.

It is not too hard to write a Filter based controller/router with
integrated security. If you were to embark on this, I would recommend
you take a thorough look at what you have already and consider what
you can reuse and what you can't - you are effectively working to a
whole new requirement.
