Kerberos authentication

[Igor Galić]

Hello Happy people,

I'm cross-posting this to tomcat and archiva.

In our company we have a well established Active Directory infrastructure,

I'm running an Apache Archiva 1.3.1 installation in Tomcat 6, on Solaris 10.
The OS has been Kerberos enabled and I would very much like to make
use of this for Tomcat/Archiva in order to provide secure authenticated
access to it.
We need to provide secure and scalable authentication.
Thus, everything else has been ruled out:

* No authentication -- not good, because we need some form of
auditing on who uploaded/deployed what (i.e.: who broke it)

* SSH/SCP doesn't scale from an administration point of view
(i.e.: we'd have to do something. That could be done wrong,
forgotten about or any number of things when people have to do
mundane tasks)

* Basic authentication -- not so good from an admin's point
of view, because clear-text passwords are stored in a
Developer's settings.xml. Not so good from a developer's
point of view, because s/he has to change their password
in settings.xml every month or so. (sic)

Given the lack of (official) documentation:
http://www.google.com/search?hl=ensitesearch=tomcat.apache.orgq=kerberos+OR+krbaq=faqi=aql=oq=gs_rfai=
http://wiki.apache.org/tomcat/FrontPage?action=fullsearchcontext=180value=kerberos+krbfullsearch=Text
http://www.google.at/search?client=operarls=enq=site:archiva.apache.org+kerberos+OR+krbsourceid=operaie=utf-8oe=utf-8
http://www.google.com/search?hl=endomains=cwiki.apache.org%2FARCHIVAsitesearch=cwiki.apache.org%2FARCHIVAq=kerberos+OR+krbsitesearch=cwiki.apache.org%2FARCHIVAaq=faqi=aql=oq=gs_rfai=

I was wondering if that's even in remotely in scope of
either Project.
It seems fairly simple to integrate Tomcat into a
Kerberos Infrastructure (although I haven't had the time
to do this so far), the question that remains unanswered
to me is how to make Archiva profit from such integration.

I appreciate any kind of feedback from people who similarily
are stuck between a rock and a hard place, and even more so
from those who have a sensible solution :)

So long,
i

That's probably true actually.  I misread* the exception.

Presumably you're catching and rethrowing the exception, using the wrong
exception, because these two shouldn't interact like this.

javax.comm is reporting that the port is already in use
(PortInUseException), possibly because you've left one of your other
versions of the program running in the IDE still.

Stop them, before running Tomcat.

If there are no other programs connected to the port, then we need to
know more about how and when the javax.comm code you've implemented runs
and how you are testing it.

Is it in a Listener or a Servlet?  Where is it defined in this class?

Either way, I suspect that this model isn't going to work very well.

Configuring which Servlet is invoked

[Christopher Dodunski]

Hello,

I have a slight problem, and am having difficulty determining which part
of the Tomcat documentation applies in my case.

Apache HTTP Server version (as proxy): 2.2.9 (Debian)
Tomcat version: 6.0.29

**My Problem**
Apache Roller weblogger is running on Tomcat with ROOT context, and is
hosting several blog pages, each with a unique domain (Roller supports
this).  Here are two:

http://blog.bread.co.nz
http://blog.christopher.net.nz

By way of mod_proxy, requests to the above are forwarded on to Tomcat, AJP
port 8009.  Moreover, mod_rewrite modifies the URLs thus:

http://blog.bread.co.nz/bread/
http://blog.christopher.net.nz/christopher/

Roller uses the last part of the URL to determine which particular blog to
serve up.  In the first example, bread.  However, the second isn't
working as intended.

Because I also happen to have an unrelated web application running at
webapps/christopher (bearing in mind that Roller is found at
webapps/ROOT), requests to the second URL above are being forwarded on to
webapps/christopher.  So the response comes from a Servlet found here, and
not from Roller.

I imagine adding a directive to server.xml will have the situation sorted.
 Obviously, webapps/christopher should respond to requests made to
http://my_main_domain:8080/christopher.  But webapps/ROOT should respond
to requests made to http://blog.christopher.net.nz/christopher.

I'd appreciate some help in getting this sorted.  In the meanwhile, I've
had to switch webapps/christopher off.

Thanks  regards,

Chris.

Well, in the former case, some class in javax.comm is throwing a
PortInUseException.

The latter case may be a separate problem.

Are you deploying a .war file to Tomcat?

If so, exactly how are you doing that?

Please remove all of the comments  any passwords from your server.xml

Starting/Stopping Tomcat from Java program

[kshitij chandrasen]

 Hi,
 I've to write methods on calling which i'd be able to start and stop the 
 tomcat app server. I tried this -
 I'm using Tomcat 6.0.26.
 String[] command = new String[4];

 command[0] = cmd;
 command[1] = /C;
 command[2] = startup.bat;
 command[3] = C:\\;
 String x[] = {PATH=C:\\Program Files\\Apache Software Foundation\\Apache 
 Tomcat 6.0.26\\bin,CATALINA_HOME=C:\\Program Files\\Apache Software 
 Foundation\\Apache Tomcat 6.0.26,JAVA_HOME=C:\\Program 
 Files\\Java\\jdk1.6.0_21,JRE_HOME=C:\\Program Files\\Java\\jre6};

 Process p = Runtime.getRuntime().exec(command,x);

 This gives me a strange windows error saying - The system cannot find the 
 file -Djava.util.logging.config.file=C:\Program Files\Apache Software 
 Foundation\Apache Tomcat 6.0.26\conf\logging.properties, while it actually 
 exists.

 If instead of setting the path, I give the absolute path of startup.bat in 
 command[3], it works fine -
 Process p = Runtime.getRuntime().exec(cmd /C start 
 C:\\broadway\\bat\\startup.bat); //I copied the startup.bat to a folder and 
 ran it from there, it worked fine.

 Please give me pointers to the right direction!

Re: Configuring which Servlet is invoked

[Christopher Dodunski]

Hi,

Thanks, but I'm not quite clear on how to direct Tomcat to call the ROOT
application for a given domain.  I added the bottom Host element to
server.xml, but it doesn't appear to work correctly.

Engine name=Catalina defaultHost=localhost
  Host name=localhost  appBase=webapps unpackWARs=true
autoDeploy=true xmlValidation=false xmlNamespaceAware=false
  /Host
  Host name=blog.christopher.net.nz appBase=webapps/ROOT /
/Engine

Previously, the URL http://blog.christopher.net.nz/christopher called up
webapps/christopher, when it should instead have been handled by Apache
Roller running with ROOT context.  Now that I have added the above
directive, Tomcat reports The requested resource () is not available.

The URL http://blog.bread.co.nz/bread is handled by Roller, as intended,
because there is no competing application at webapps/bread.

Regards,

Chris.

It is difficult to respond clearly to your questions, because they seem to be based on the 
wrong premises, and/or they are confusing as to what you are really trying to achieve.

We also have no idea what the ROLLER application is, and how itself needs to be 
set up.

But here are some basic principles :

1) this line :
 Engine name=Catalina defaultHost=localhost
indicates which one of your Host below, is the default host.
The default Host is the one which will handle any request which arrives at this server, 
and for which the hostname does not match one of the other Host tags.

In you case thus, this
Host name=localhost..
is the default Host.

2) each separate Host should have a separate appBase, not overlapping the 
others.
So, having one Host with appBase=webapps, and another Host with appBase=webapps/ 
is a nono, you should not do that.
Create another directory, for example (tomcat_dir)/webapps-blog, and use that one to put 
the applications related to your host blog.christopher.net.nz, like

Host name=blog.christopher.net.nz appBase=webapps-blog /
(You can also define this directory totally outside the hierarchy of the main Tomcat, like 
at /var/websites/blog.christopher.net.nz, and then use

Host name=blog.christopher.net.nz 
appBase=/var/websites/blog.christopher.net.nz /

3) within each applications base (appBase), each application will correspond to a 
directory, with the same name as the application.
So for example, under (tomcat_dir)/webapps/, you can have one application called app1 
and another called app2, for a structure like this

  tomcat_dir/webapps/
app1/
app2/

4) To call any of these applications, you will use a URL like :
   http://host-name/app1
   http://host-name/app2
   etc..

5) the special name ROOT is reserved for the default application within a 
Host.
   That is the application which users would get if they simply entered
   http://host-name/

So, to modify the structure given above so that there would be, in addition to app1 anbd 
app2, a default application, you would have :


  a) a file structure like this :
  tomcat_dir/webapps/
ROOT/
app1/
app2/
and users could ask for :

   http://host-name/  (to get the default application)
   http://host-name/app1  (to get the app1 application)
   http://host-name/app2  (to get the app2 application)

Does this clarify things ?

Connecting Tomcat 6.0.26 to MySQL 5.1

[m.oshea]

Hello

Having rebuilt my Windows PC, I am trying to get Tomcat running under NetBeans 
to connect to MySQL.

I believe MySQL is alright because the various tools retrieve data correctly. 
But when my Java web app is run from NetBeans, Tomcat shows the homepage but 
then gives a Java null pointer error. The logs tell me this is to do with 
retrieving user data from the database. So I'm assuming that the two system 
components are not able to talk to each other. But why?

I have mySQLConnector in the NetBeans library my web app is using. I've placed 
MySQL Connector in Tomcat's config folder, MySQL Connector is also in the 
classpath of the PC. The context.xml file in the web app is set to use the root 
user in MySQL and all relevant authorities in MySQL are set.

But I get nothing! Although I have the same tools on another PC and they are 
fine.

Any ideas? Is there something I've missed?

Thanks

Martin O'Shea. 

Thanks

RE: Starting/Stopping Tomcat from Java program

[Rob Gregory]

I call the scripts via code to both stop and start Tomcat. There is a
problem with even calling these scripts via Unix unless you change (cd)
into the bin directory before running startup.sh as the log paths are
generated relative to the startup.sh location.


String strCatalinaBin = System.getenv(CATALINA_HOME) +
\\bin\\;
File objDir = new File(strCatalinaBin);
r = Runtime.getRuntime();
p = r.exec(new String[] { cmd.exe, /C, start,
strCatalinaBin + catalina.bat, start }, null, objDir);

p.waitFor();
p.destroy();

Hope this helps.

 Subject: Starting/Stopping Tomcat from Java program
 
 
  Hi,
  I've to write methods on calling which i'd be able to start and stop
the
 tomcat app server. I tried this -
  I'm using Tomcat 6.0.26.
  String[] command = new String[4];
 
  command[0] = cmd;
  command[1] = /C;
  command[2] = startup.bat;
  command[3] = C:\\;
  String x[] = {PATH=C:\\Program Files\\Apache Software

  Process p = Runtime.getRuntime().exec(command,x);
 
  This gives me a strange windows error saying - The system cannot
find the
 file -Djava.util.logging.config.file=C:\Program Files\Apache Software
 Foundation\Apache Tomcat 6.0.26\conf\logging.properties, while it
actually
 exists.
 
  If instead of setting the path, I give the absolute path of
startup.bat in
 command[3], it works fine -
  Process p = Runtime.getRuntime().exec(cmd /C start
 C:\\broadway\\bat\\startup.bat); //I copied the startup.bat to a

  Please give me pointers to the right direction!

Re: disabling session management

[emerson]

Hi Christopher

 Which classes, specifically?

Thousands of Session instances inside the sessioins attribute of the
org.apache.catalina.session.StandardManager.
In theory we are not calling getSessions on the middle tier and as you
mentioned, we have no JSPs either.

However, we might be passing a jsession parameter from the frontend to
the middle tier. Would that be an issue, causing the session to be
created in the middle tier?

 What is the impact of using session-timeout = 0?

 Your sessions will never time out, and your problem will likely get worse.

In the only place I see any reference to it is here:
http://tomcat.apache.org/tomcat-6.0-doc/api/org/apache/catalina/session/StandardSessionFacade.html#setMaxInactiveInterval(int)

And it says that A negative time indicates the session should never
timeout.. there is no mention about setting as 0.

Regards
Emerson

 This is on our middletier servler, where sessions are irrelevant.

 Okay, great.

 Is there a way to disabled session management for this server?

 Don't call request.getSession(). If you have JSPs (in a middle tier?),
 make sure they all have session=false in their @page directives.

 What is the impact of using session-timeout = 0?

 Your sessions will never time out, and your problem will likely get worse.

 We currently use 30 minutes for the session-timeout.

 You could always set it to 1 minute just to be sure they don't last very
 long if they are accidentally created.

Subject: Connecting Tomcat 6.0.26 to MySQL 5.1



Hello

Having rebuilt my Windows PC, I am trying to get Tomcat running under NetBeans 
to connect to MySQL.

I believe MySQL is alright because the various tools retrieve data correctly. 
But when my Java web app is run from NetBeans, Tomcat shows the homepage but 
then gives a Java null pointer error. The logs tell me this is to do with 
retrieving user data from the database. So I'm assuming that the two system 
components are not able to talk to each other. But why?

I have mySQLConnector in the NetBeans library my web app is using. I've placed 
MySQL Connector in Tomcat's config folder, MySQL Connector is also in the 
classpath of the PC. The context.xml file in the web app is set to use the root 
user in MySQL and all relevant authorities in MySQL are set.

But I get nothing! Although I have the same tools on another PC and they are 
fine.

Any ideas? Is there something I've missed?

Thanks

Martin O'Shea.

Re: Starting/Stopping Tomcat from Java program

[André Warnier]

Hi.

I do not really understand the issue here.
If you are under Windows, with Tomcat running as a Service, then you can just run the 
commands net start tomcat6 / net stop tomcat6 to start/stop tomcat.
If you are under Linux, then you can just issue the command /etc/init.d/tomcat6 
(start|stop).

Under most Unixes, the procedure is similar.
So where is the problem ?

RE: [OT] Disable class monitoring for reloading container classes

[Jeffrey Janner]

I really think all times should be stored Zulu Standard Time, and then 
converted only for display purposes. 
This does make the conversion process more complicated, as the system has to 
have all timezone/dst tables for Forever to properly display the time to the 
user for that particular point in time to whatever the user's TZ was at that 
time.  All comparatives are done on raw standardized data.  (Yes, you don't 
have to do GMT for your base, but you might as well.)

RE: JSESSIONID weakness Severity in Tomcat 6.0.29?

[Brian]

Hi Mark,

Well, it seems that www.securitymetrics.com got crazy! They already told me
that they made some changes in their system, and now they are having
problems (bugs).
I was just asking myself: How can their automatized procedure know if I am
vulnerable to the session fixation problem, if it doesnt know a valid
user+password, so it is not being able to actually login to my system?

Anyway, something good came from this: I realized that actually my system
was not safe to session fixation. After the login process, it was not
invalidating the session and creating a new one. Now it is. I just had to
program the system to save the attributes, invalidadte the current session,
create a new one, and recreate the attributes. Fortunately, Tomcat generates
a new session ID for the new session. It seems that it was not happening in
the previous versions of Tomcat and in other containers (according to what I
have read in some forums), but now it is.

Thanks for all your help!

  What do you mean exactly with app managing its own authentication?
  Sorry if it is a dumb question.
 
 If you use Tomcat's authentication (BASIC, FORM, etc) then Tomcat will
change
 the session ID on authentication and therefore protect against session
fixation.
 
 If the app has its own authentication mechanism it is possible that the
session ID
 will not be changed on authentication creating the possibility for a
session
 fixation attack.

 Yep, although that is looking at Tomcat 7. The session fixation protection

back-ported
 to Tomcat 6.

Re: Tomcat 5.5.25 | Memory leak in Web Application

[Anurag Kapur]

The objects holding references to the character arrays that ultimately
consume all the memory are of type
org.apache.jasper.runtime.BodyContentImpl as indicated in the object
reference tree below:

There was a bug reported in Tomcat 5.5.9 which says

The problem is that this huge array never gets reset due to the object pooling
implementation in Jasper (JspFactoryImpl maintains a pool of PageContextImpl
objects. Each PageContextImpl object maintains an array of BodyContentImpl
objects), so the memory it consumed is never returned to the heap.

https://issues.apache.org/bugzilla/show_bug.cgi?id=37793

We do not use the suggest JVM argument in our Tomcat 5.5.27 JVM
-Dorg.apache.jasper.runtime.BodyContentImpl.LIMIT_BUFFER=true

Could adding this argument to the Tomcat JVM resolve the problem?

I suspect it would only work if the app has JSPs which were pre-compiled

Re: Error 503 ocurring when server under load

[Rob G]

Christopher Schultz wrote This directive has been deprecated since 1.2.16.
 Cachesize defines the number of connections made to the AJP backend that
 are maintained as a connection pool. It will limit the number of those
 connection that each web server child process can make.

 Cachesize property is used only for multi threaded web servers such as
 Apache 2.0 (worker), IIS and Netscape. The cachesize property should
 reflect the number of threads per child process. JK will discover the
 number of threads per child process on Apache 2 web server with
 worker-mpm and set its default value to match the ThreadsPerChild
 Apache directive. [...]
 

 Since mpm_winnt (like mpm_worker) uses ThreadsPerChild to set the number
 of worker threads (and therefore simultaneous requests that can be
 accepted), you'll have to know what ThreadsPerChild is set to. That's
 easy: just search for that directive in httpd.conf. If it's not there,
 or commented-out, the default is 64 on mpm_winnt
 (http://httpd.apache.org/docs/2.0/mod/mpm_common.html#threadsperchild).

 If you've left it as the default (64) and you've set worker.cachesize
 (really worker.connection_pool_size) to 10, then you can accept 64
 connections from clients but only call-out to Tomcat over 10 of those
 connections: the others will have to wait. I'm not sure what the
 scheduling algorithm is for choosing which thread gets the next
 available connection from the pool (FIFO?), but it's very possible to
 starve your clients even after 10 simultaneous connections.

So if I'm reading your email and the docs correctly. I should just
comment out the cachesize=10 from the workers.properties. And since
for connection_pool_size (that replaced it)  JK  will discover this
number for the Apache web server automatically and set the pool size
to this value, I don't need to add anything to the workers.properties
file?

Re: Configuring which Servlet is invoked

[Christopher Dodunski]

Hi,

Thank you André for your clear explanation below.  I am aware already of
how the directory structure relates to URL formation and, thanks to you
and others, now understand the significance of Host elements within an
Engine.  And I see how the default host is configured.

It doesn't, though, quite answer my particular issue.  Apache Roller is a
weblog server, that handles multiple domains - e.g. blog.host1.com,
blog.host2, etc.  But, at the present time, to correctly form URLs within
the HTML it serves up, Roller must run as the default Tomcat application. 
Therefore, it is installed at /usr/local/tomcat/webapps/ROOT.

Here is what is happening:

1) HTTP request comes into my webserver with the URL:
http://blog.christopher.net.nz
2) Apache HTTP server receives this on port #80
3) mod_rewrite appends /christopher to the end of the URL of the request
header (Roller recognises this as the handle, so it serves up the
correct blog page)
4) mod_proxy forwards request on to Tomcat's AJP port #8009
5) Tomcat receives this but, with the current configuration, invokes the
application at webapps/christopher.  Instead, I would like it to invoke
the default (Roller) application at webapps/ROOT.

Interestingly, if I browse to another domain hosted by Roller -
http://blog.bread.co.nz(/bread) - as I don't happen to have an application
at webapps/bread, Tomcat handles this fine.  The default application
(Roller) serves up the weblog for handle=bread.

Thanks  regards,

Chris.

 Hi,

 Thanks, but I'm not quite clear on how to direct Tomcat to call the ROOT

 Previously, the URL http://blog.christopher.net.nz/christopher called up
 webapps/christopher, when it should instead have been handled by Apache
 Roller running with ROOT context.  Now that I have added the above
 directive, Tomcat reports The requested resource () is not available.

 The URL http://blog.bread.co.nz/bread is handled by Roller, as intended,
 because there is no competing application at webapps/bread.

 It is difficult to respond clearly to your questions, because they seem to
 be based on the
 wrong premises, and/or they are confusing as to what you are really trying
 to achieve.
 We also have no idea what the ROLLER application is, and how itself needs
 to be set up.

 But here are some basic principles :

 1) this line :
   Engine name=Catalina defaultHost=localhost
 indicates which one of your Host below, is the default host.
 The default Host is the one which will handle any request which arrives at
 this server,
 and for which the hostname does not match one of the other Host tags.
 In you case thus, this
 Host name=localhost..
 is the default Host.

 2) each separate Host should have a separate appBase, not overlapping
 the others.
 So, having one Host with appBase=webapps, and another Host with
 appBase=webapps/
 is a nono, you should not do that.
 Create another directory, for example (tomcat_dir)/webapps-blog, and use
 that one to put
 the applications related to your host blog.christopher.net.nz, like
 Host name=blog.christopher.net.nz appBase=webapps-blog /
 (You can also define this directory totally outside the hierarchy of the
 main Tomcat, like
 at /var/websites/blog.christopher.net.nz, and then use
 Host name=blog.christopher.net.nz
 appBase=/var/websites/blog.christopher.net.nz /

 3) within each applications base (appBase), each application will
 correspond to a
 directory, with the same name as the application.
 So for example, under (tomcat_dir)/webapps/, you can have one application
 called app1
 and another called app2, for a structure like this
tomcat_dir/webapps/
  app1/
  app2/

 4) To call any of these applications, you will use a URL like :
 http://host-name/app1
 http://host-name/app2
 etc..

 5) the special name ROOT is reserved for the default application
 within a Host.
 That is the application which users would get if they simply entered
 http://host-name/

 So, to modify the structure given above so that there would be, in
 addition to app1 anbd
 app2, a default application, you would have :

a) a file structure like this :
tomcat_dir/webapps/
  ROOT/
  app1/
  app2/
 and users could ask for :

 http://host-name/  (to get the default application)
 http://host-name/app1  (to get the app1 application)
 http://host-name/app2  (to get the app2 application)

Hi André,

So, based on your explanation below, Tomcat can actually have more than
one default application?  It can have one for each and every Host?  This
is most interesting.  I had assumed that the default application had to be
installed at webapps/ROOT (or anywhere else the default host's appBase
happened to be).

RE: Configuring which Servlet is invoked

Hi,

Okay, I have now set up two Host elements inside server.xml with
appBases in two entirely different places...

Engine name=Catalina defaultHost=localhost

  Host name=localhost  appBase=webapps
unpackWARs=true autoDeploy=true
xmlValidation=false xmlNamespaceAware=false
  /Host

  Host name=http://blog.christopher.net.nz;
appBase=/home/roller/application
unpackWARs=true autoDeploy=true
xmlValidation=false xmlNamespaceAware=false /

/Engine

Have restarted Tomcat, but Tomcat isn't unpacking
/home/roller/application/ROOT.war as expected.  The catalina.out log
doesn't seem to give a reason.  Have I missed an important step?

Thanks,

Chris.

RE: Configuring which Servlet is invoked

[Christopher Dodunski]

Hi Chuck,

The unpacking matter is now sorted - Tomcat didn't have write access.

Regarding which is default host, I already have several applications
hosted on Tomcat, and these are called by Apache HTTP (proxy) server like
so:

ProxyPass /tomcat ajp://127.0.0.1:8009/christopher/
ProxyPassReverse /tomcat ajp://127.0.0.1:8009/christopher/

My preference would be to leave localhost/127.0.0.1 as the default host. 
All applications (except Roller) are installed at
/usr/local/tomcat/webapps.

Roller hosts multiple domains, and so I can't see how this can be the
default host.  I thought the best option might be to set up a Host for
each domain Roller serves, all with appBase=/home/roller/application. 
Is this the best solution in your opinion?

Thanks,

Chris.

 can be the default host.

That is exactly the situation where you want it to be the defaultHost, so you 
don't have to configure a Host per domain.  However, that does restrict you 
to one default webapp servicing all of the domains.  Either that webapp or a 
filter can route each request to the proper domain-related webapps, if needed.

 I thought the best option might be to set up a Host
 for each domain Roller serves, all with
 appBase=/home/roller/application. 

Not good.  You should have a separate appBase for each Host.  If you don't, 
incorrect deployment may occur based on the timing of each Host seeing the 
webapps underneath the shared appBase.  If you run with expanded directories 
rather than .war files, it may work, but it's not recommended.

RE: Configuring which Servlet is invoked

What I probably omitted to say is that localhost is likely to be
associated with many more domains than the Roller application alone.  So
marrying the default host to Roller isn't likely to save me work. 
Instead, I have added Alias elements to the Roller host for each blog
domain.

And so far so good!  Roller serves up the bread blog with
http://blog.bread.co.nz, and Tomcat no longer invokes webapps/christopher
(a localhost app) with http://blog.christopher.net.nz.  However, it
doesn't appear to invoke Roller either.  Instead Tomcat reports The
requested resource () is not available.  Why is host below invoking
Roller for some of the Alias elements, but not all?  Puzzling!

  Host name=blog.optomus.com appBase=/home/roller/application
unpackWARs=true autoDeploy=true
xmlValidation=false xmlNamespaceAware=false
Aliasblog.bread.co.nz/Alias
Aliasblog.capereinga.co.nz/Alias
Aliasblog.doubtlessbay.co/Alias
Aliasblog.christopher.net.nz/Alias
Aliasblog.isaac.net.nz/Alias

Is it a Tomcat requirement that additional hosts (appBase) must each
contain manager and host-manager?  This appBase currently contains
ROOT (Roller) only.

The first two errors above make no sense to me.
