If all you want is to customize the Connector, then it is much easier to
simply put into server.xml:
<Connector protocol="com.myfirm.mypackage.MyHttp11ProtocolHandler" ... />
Then, if I understand what you want, something like:
public void init() throws Exception {
fixupSettings(); // your method to make configuration changes
super.init(); // let Tomcat handle the rest
}
should work for you.

Thank you.

Could it be that there are several threads that have access to the
same Response object? (That is illegal).
You can try setting the ...RECYCLE_FACADES property to "true", see the
full name of it and description in
http://tomcat.apache.org/tomcat-6.0-doc/config/systemprops.html
You can add it to the end of the catalina.properties file.

I do not see what else can cause randomness in writing out a response.
Different length of headers? I see that you have
maxHttpHeaderSize="50000"

Are you using Tomcat-Native (tcnative-1.dll, libtcnative-1.so)?
I see that you have an AprLifecycleListener in your server.xml. Does
it print a warning that tomcat-native is not present when Tomcat is
started? You can comment it out to disable Tomcat-Native and to
disable that warning message if you are not going to use it.
See
http://tomcat.apache.org/tomcat-6.0-doc/config/listeners.html

Never mind, got it. I was using JAVA_OPTS instead of CATALINA_OPTS.

Not really an expert, but 2 methods come to mind :

1) maybe the most serious :
Each Tomcat runs in its own JVM. There should be some JVM
system.properties which determine that kind of thing, which should be
settable with -D options on the java line that starts Tomcat.

Really, I don't really know this. But a previous issue of mine with a
webapp that was resetting the language for the whole JVM leads me to
believe this might work.

2) less serious :
Install VMWare server. Configure as many virtual machines as you need
Tomcats. Give each its timezone and run a Tomcat in each.

I Have Multiple Tomcat Instances, Now I Want Each to Run In a Different Time Zone

2009-11-24T16:34:58Z

I want to run multiple instances of tomcat on the same server, one
instance for each time zone. I have all the separate tomcats running
fine, but they are all using the server's time zone. I've been Googling
and have not found an effective way to do it. Can someone please tell me
how?

Re: Which version of Tomcat to use on Centos?

2009-11-24T16:27:01Z

Thanks guys, good responses, I think I'll not use the Centos packages
and go with the "official" versions for the reasons mentioned.

Re: config database in Tomcat

2009-11-24T16:12:00Z

As this is a part of the hibernate configuration rather than the
database / datasource configuration the SQL dialect has to be configured
in the hibernate configuration file, not in the context.

Here's my SessionFactory class just in case:

I don't think we got to the bottom of why that was happening. I was
hoping the problem would be in the same method, but it's not in exactly
the same location for both.

The append(byte[], int, int) method is implicated in both, and in both
cases an 8k byte buffer was in use in the app code.

@Geoffrey - can you try using a smaller (say 4k) byte buffer instead,
and adding some code to count how many bytes have been sent when the
error occurs?

Internet Telepathy is an unpleasant condition and it is fairly

Applying my psychic abilities... you're Tomcat running on a computer
with a firewall that's enabled by default, and you've not added an
exception for Tomcat (on port 80).

But since you've not told us about your OS, Tomcat version or anything
else, that's just a guess from being psychic and seeing the same
problem asked on the list about once a week for the last 3 years ;-).

Considering that this is the support list for "the official Tomcat", let
me give you a nevertheless measured and reasoned answer : it depends.

- If you want further support for your problems from this list, then I
strongly suggest that you de-install OpenJDK 1.6, and install the Sun
JDK 1.6 instead. Then, it will also simplify your future interactions
with this list, if you install the latest official Tomcat 6 version
available from the official Tomcat site, rather than the CentOS package.

- If on the other hand, you prefer to get all your future support not
from this list, but from the CentOS lists, then go ahead and install the
CentOS stuff.

Just don't mix and match.

People on this list generally do not use OpenJDK 1.6, and do not know
how the packagers of the CentOS Tomcat package arrange the files over
the file system, nor what they put in their Tomcat configuration files.
So it is really difficult to help someone in case of trouble with these
other packages.
That does not mean that the CentOS packages are bad, it just means that
on this list you will not get much help with them.

You should always use the versions obtained from http://tomcat.apache.org
.
Unless you have some particular reason to use Tomcat 5, you should
install Tomcat 6.

Hmm. I don't know, but I'll make some guesses :

Which version of Tomcat to use on Centos?

2009-11-24T14:11:21Z

Hi All,

I've got a new server running the latest Centos. I want to install
Apace tomcat on there.
Should I use tomcat5 installed via yum, or instead use the "original"
version from http://tomcat.apache.org?
Also, my server currently has OpenJDK1.6. For max. reliability and
least hassles is this the best JVM to use with Tomcat or should I use
the original version from Sun?

Tomcat in Embedded mode

2009-11-24T12:08:42Z

Hi guys,

I spent my day into struggling with Tomcat 6 and I just wanted to ask you
for some ideas and whether what I'm doing seems right to you.

So, I'm trying to port a legacy application which is using Tomcat 5.0.28 to
Tomcat 6.0.20.
While most of the Tomcat 5.0.28 properties are read from the server.xml,
some of the Connector properties(keyStore, keyPass, protocols, connector
address, port ...) are retrieved from other configuration files which are in
fact related to the application.
Using Tomcat 5.0.28 this is implemented by providing a custom implementation
for the CoyoteConnector and CoyoteServerSocketFactory.

Obviously, I can't do this with Tomcat6.
What I intend to do is write a class that extends the Catalina class (so
that the Digester can read my server.xml file) and then just overwrite the
addConnector method in order to overwrite the Connector properties "on the
fly" and the load method ( so that I can push my implementation in the
digester).

Then in order to use the Bootstrap (to load classes), I'll have to extend it
so that I can change the Catalina implementation with my own.
Then for starting tomcat I'll use my bootstrap.

Please, have in mind that I really don't like this hacky approach. However,
I can't do much to change it since I'm not the one who tells the
requirements.

So, what do you think? Some easier way to achieve this?

Thanks,
Ivelin

What connectors are you using? Is it HTTP, or AJP? What is your
configuration as a whole?

There was the following bugreport recently:
https://issues.apache.org/bugzilla/show_bug.cgi?id=48105

The reporter of issue 48105 wrote that he saw exceptions in 6.0.18,
.20 as well, but no stack traces were provided, so it is unconfirmed.

Not entirely true. Check the bottom of this page :
http://wiki.apache.org/tomcat/Tomcat_and_IIS_Howto

Now, don't ask me how I got to that page. I started with the FAQ about
JK Connectors, and followed various links from there..

Ah ok, fair enough. I was following this http://tomcat.apache.org/connectors-doc-archive/jk2/jk/iishowto.html and on the IIS side I was probably relying too much on past experience.

But hopefully information about that Web Extensions setting will help others. I googled a lot of posts where people were stuck at the same stage. And many thanks for your replies.

Re: IIS redirect stops at [xxx] is a servlet url - should redirect to ajp13

Thanks for your help. There is a new IIS permissionings section for filters, I had to add a new web extension there and all was good.

The doc says that userPattern can be used *instead of* userSearch, userSubtree, and userBase; no mention is made of what happens when you specify all of them, but it wouldn't surprise me that things get confused.

Also, it seems odd that the roleName attribute is part of the roleBase - that doesn't seem to make any sense.

> I note that I get a warning message about the debug="99" property,

The debug attribute hasn't been used in quite some time, but the doc lags behind.

Not directly related to what your current issue is, but just as
information :
http://www.ioplex.com/jespa.html

I am using that in Windows environments, and it really works out of the
box, for thousands of users.

A bit of explanatory philosophy, because this subject comes up so often :

I have found that in the practice, there is a certain amount of
confusion at the interface between the Java/Open Source world, and the
corporate Windows-centric world.
When a Unix/Linux/Open Source developer type asks the corporate
MS-Windows sysadmin type what the "network user authentication method"
is, very often the answer will be "Active Directory".

In fact, it isn't.

AD is just the database back-end used by Windows Domain Controllers,
which are, for all the Windows workstations, the real authenticators.
The real authentication which happens is the Microsoft "NTLM"
authentication, which is a complicated and sometimes annoying multi-pass
exchange between browsers and Windows domain Controllers. Workstations
never talk directly to the AD server, they talk to the DCs.
Workstations do not talk LDAP protocol, they talk NTLM protocol.
Similarly, IIS webservers, and MS proxy servers, talk to a DC to
authenticate the users accessing them from their browsers. They do not
talk directly to the AD server.

That the Windows DCs themselves use a back-end AD server is pretty much
irrelevant in the end.

Jespa is a servlet filter, which you install like any servlet filter,
"around" a webapp. It automatically authenticates a Windows workstation
user accessing the webapp, on the base of his network domain login-id,
which he entered when he turned on his PC this morning and logged in to
the Windows domain.
Jespa does that by talking to the DC, just like IIS would do.
If it gets a valid domain user-id from the browser, it passes this
user-id to Tomcat. A webapp can then retrieve it in the normal way, via
calls such as getRemoteUser(). The Jespa module, in its later
incantations, can also "translate" Windows user's group membership in
the Tomcat concept of "user role".
The additional benefit is that in most cases, all this happens
transparently to the user, who never even sees a login dialog.
So basically, you also get SSO for free.

There used to be an open source similar solution available, made by the
same people who make jCIFS (at samba.org). It was called the "jCIFS
HTTP NTLM authentication filter" or similar. But that software is no
longer developed or maintained, and does not work with recent revisions
of the Windows NTLM protocol (v2, as standard since Vista and beyond).
Jespa works with all NTLM versions.

Allthat I am saying in the paragraphs above, applies totally only if all
the Tomcat users which you wish to authenticate, are first logged-in in
a Windows domain, before they call up a Tomcat-based application.
If you also have users who contact the Tomcat servers from outside a
Windows domain (such as from the Internet without a corporate VPN e.g.),
then you are out of luck, and you will have to do another kind of
authentication, such as presenting users with a login screen and using a
direct interface to the AD server.
But in 99% of the corporate cases, what I describe above is the easiest
solution. (and it also works with Firefox, not just with IE).

These must be opened by some webapp, not Tomcat itself.

Removing the redirectPort attribute merely causes it to have the default value of 443. It does not eliminate the redirection should an HTTPS request every show up.

Something is ringing a bell. Search the list archives & see if you can
find anything similar, I have a feeling that someone had a similar
problem recently.

I'll look myself when I get a chance later.

AD Authentication

2009-11-24T09:44:50Z

Hi all,

I'm trying to get Tomcat to authenticate against Active Directory, but
failing
in that all I seem to get back is the following error:

24-Nov-2009 17:10:18 org.apache.catalina.realm.JNDIRealm authenticate
SEVERE: Exception performing authentication
javax.naming.NamingException: [LDAP: error code 1 - 000020D6: SvcErr:
DSID-031006CC,
problem 5012 (DIR_ERROR), data 0 ]; remaining name
'sAMAccountName=spenn'
at com.sun.jndi.ldap.LdapCtx.mapErrorCode(LdapCtx.java:3081)
...

I've no idea what this error means, and googling for it seems to find it
listed in several log files, but never as the subject of a post, and hence
no answers about what it means or how to resolve it.

So, onto the details...

I'm using Tomcat 6.0.20 with JDK 1.6 on Windows Vista 64. In my server.xml
I have
the following:

<Host name="localhost" appBase="webapps"
unpackWARs="true" autoDeploy="true"
xmlValidation="false" xmlNamespaceAware="false">

<Context path="/l3">
<Realm className="org.apache.catalina.realm.JNDIRealm" debug="99"
connectionURL="ldap://172.17.10.100:389"
connectionName="cn=SvcUser,cn=users,dc=myorg,dc=local"
connectionPassword="********"
userBase="ou=staff,dc=myorg,dc=local"
userPattern="sAMAccountName={0}"
roleBase="cn=users,dc=myorg,dc=local"
roleName="cn"
roleSearch="(member={0})"
roleSubtree="false"
userSubtree="true"
authentication="simple"
referrals="follow"
/>
</Context>
</Host>

I note that I get a warning message about the debug="99" property, saying
"Setting property 'debug' to '99' did not find a matching property." I
don't
think this is serious, but it's copied out of various example files so I'm
surprised it doesn't appear to work.

In my web.xml for my application, I have the following:

<security-constraint>
<web-resource-collection>
<web-resource-name>L3 Application</web-resource-name>
<url-pattern>/*</url-pattern>
</web-resource-collection>

<auth-constraint>
<role-name>ECM Team</role-name>
</auth-constraint>
</security-constraint>

<security-role>
<description>
The role that is required to log in to the L3 Application
</description>
<role-name>ECM Team</role-name>
</security-role>

<login-config>
<auth-method>BASIC</auth-method>
<realm-name>L3 Application</realm-name>
</login-config>

If I search for (sAMAccountName=spenn) with ldapsearch from Linux, using
the
above credentials, then ldapsearch pulls back the entry. If I try to login
to Tomcat however, it just displays the login dialog ago, and I get the
above error in the logs.

The values for login and userbase etc I've pulled from an Apache HTTPd
config,
which works, so I'm pretty certain these bits are correct.

I'm not certain about the role config however. I'd be happy at this point
if I could just authenticate and not check a user's role (though at some
point this needs to work as well), but can't figure out how to disable the
role checking (my attempts result in no authentication at all).

I've tried several variations of the above, all to no avail. Does anyone
have any ideas what I'm doing wrong? Or at least, how to get more debug out
of it so that I can see what it's actually trying to do?

Thanks for any help,

Sam.

Re: ArrayIndexOutOfBoundsException

2009-11-24T09:38:23Z

Perhaps change your code from
while((bytesRead = in.read(buf)) > 0) {

while((bytesRead = in.read(buf)) != -1) {

From api:
Reads the next byte of data from the input stream. The value byte is
returned as an int in the range 0 to 255. If no byte is available
because the end of the stream has been reached, the value -1 is
returned. This method blocks until input data is available, the end of
the stream is detected, or an exception is thrown.

There is a different amount of data sent each time before it crashes. I also tried byte by byte and gets the same error but it seems that it is less often.

At what point is the error occuring, same place each time?
If not known, try adding some debug logging to count bytes or some such.

What happens if you write byte-by-byte?

The files are up to 30GB so it is not a solution. When I try without the buffer it doesn't seem to work at all. What I mean is that the servlet sends some data before the error occurs when sending with the buffer but I get 0KB without.

How big is the file you're sending?
Is there any particular reason to use a buffer?
What happens if you try without it?

Not entirely true. Check the bottom of this page :
http://wiki.apache.org/tomcat/Tomcat_and_IIS_Howto

Now, don't ask me how I got to that page. I started with the FAQ about
JK Connectors, and followed various links from there..

Re: ArrayIndexOutOfBoundsException

2009-11-24T09:17:59Z

The bytesRead returns the size of the buffer (8KB) every time. I also debug and I can't find anything wrong. Input and OutputStream are not null, bytesRead is the correct size and the buffer is also filled.

Any other ideas?

Best Regards

Geoffrey
