Re: keeping same session via apache2 mod_jk2 and tomcat5

[Vahid Hedayati]

Hi all

I had as a test used seperate engines for each virtual host but instead it
loaded up  one of the virtual hosts on both and the site that had the wrong
virtual host loaded up seemed to keep the session ID .

Anyhow here are the configs.
The first 2 is what is currently running the last 2 are what i tried as
seperate engines.

Subject: Data Truncation Error


Hello all,

I am using a MySQL 5.0.18 server with the 
mysql-connector-java-3.1.12-bin Connector/J driver to connect to it on a 
Tomcat 5.5.15 server.  The connection works fine but occasionally when I 
try to add a Java double value to the database (a row set to 
DECIMAL(10,2))I get the following error:


com.mysql.jdbc.MysqlDataTruncation: Data truncation: Data truncated for 
column 'TotalCost' at row 1


Now I believe to solve this you have to turn data truncation off in the 
connection url.  However, when I try


url=jdbc:mysql://localhost:3306/fyp?jdbcCompliantTruncation=falseautoReconnect=true 



Tomcat fails to start and I have to remove the truncation bit so it just 
reads url=jdbc:mysql://localhost:3306/fyp?autoReconnect=true with 
which Tomcat does start up.


So how can I get rid of this error?

Many thanks

Mark Whitby

connections not freed

[Edward Quick]

Hi,

I have the following scenerio:

I'm running a jsp on tomcat 4.1.31 fronted by apache 2.0.54. This jsp uses a 
tomcat jdbc pool connection with maxWait set to 1ms. At the moment the 
database is screwed up because one of the filesystems on there has filled up 
from an archive job.


Now when I run the jsp, the code stops after successfully getting the 
datasource, and hangs indefintely on getConnection.


DataSource ds =
(DataSource)ctx.lookup(java:comp/env/jdbc/pol);
Connection conn = ds.getConnection();= gets stuck 
here


The browser also hangs, and when maxClients have logged onto the jsp, 
apache doesn't take anymore connections even after the browser has been 
shut.


Are there any timeouts or other settings on Apache/Tomcat I need to 
configure to avoid this behaviour?


Thanks for any help.

Ed.

Re: FarmWarDeployer instructions

Thank you Filip, please bear me one more time. I understand that only the 
tomcat cluster master should have a watchDir configured and watchEnabled 
set to true. The deployDir of all tomcat cluster members should point to 
the clustered Host appBase attribute; in case the Cluster element is 
defined on the Service, the directory should be the parent of the enclosed 
Host appBase attributes. Is this correct?

The watchDir doesn't have anything to do with the appBase folders and can be 
exposed using any network filesystem (eg. CIFS, DAV or NFS) as long as the 
tomcat cluster master process can access it. Is this correct?

In order to get the farm deployment running I do not have to download the 
tomcat-deployer package. Right?

If directories don't exist (especially the tempDir) will Tomcat crash and burn 
or silently fail to farm deploy?

e


 only one server should have (watchEnabled=true), this is the location
 where you deploy all your files.
 if you enable it on all servers, then just be careful so that you don't
 deploy the same file in two locations and end up with a deployment
 collission.

 tempDir=/tmp/war-temp/ -- The directory the deployer uses to assemble
 file transfers
 deployDir=/tmp/war-deploy/ -- the directory where the deployer
 deploys the WAR file to
 watchDir=/tmp/war-listen/  -- the listen directory, this is where you
 drop in a new file so that the deployer can pick it up
 watchEnabled=false --true means we are watching for new deployments,
 false means we act as a slave, only get deployments from other nodes.

RE: apache(v2.0) front-end to jboss(v4.0.3)/tomcat5.5 webapp: context path prepend ?

You will probably want to set emptySessionPath to true

http://tomcat.apache.org/tomcat-5.5-doc/config/http.html
http://marc.theaimsgroup.com/?l=tomcat-userm=114082698006999w=2

Otherwise, the browser will send the cookie for /mywebapp as that is the
context which Tomcat will set JSESSIONID under.

Unless you don't need sessions.

Controlling contents of the localhost.date.log file

[Davidian]

I've posed this question recently, but I am going to try to phrase it better,
as I think last time it may have been poorly worded...

My web application logs information to the localhost.date.log file.  The
information that is being logged is doing so correctly.  However, here is my
problem:

In between every line of logging, an additional line is ADDED, which looks
like the following:

Mar 22, 2006 4:05:04 AM org.apache.catalina.core.ApplicationContext log

Again, a line like this appears every other line in the localhost.date.log
file.  The lines that I want logged already include the date, so these lines
are uneeded, and clutter up the log file quite a bit.

My question: how do I get rid of these lines?  I have already written my own
java.util.logging.Formatter subclass, but this doesn't work.  It appears
that the formatter does not insert these lines.  My Formatter only affected
the lines that my webapp is logging, not the lines in question.

Does someone know how to stop these extra lines from being logged?

Thank you very much.

Desupport for Tomcat 4?

Hello,
Do you know when the tomcat development group plans on not releasing any new
patches for Tomcat 4? Does this ever happen? If a bug is found in Tomcat 4
is it fixed in Tomcat 4 or are we forced to upgrade to Tomcat 5?

Thank you for your time!

Look at this:
http://tomcat.apache.org/whichversion.html
The fact that this section
http://tomcat.apache.org/whichversion.html#Apache%20Tomcat%204.x
cantains twice the encouragement to upgrade to Tomcat 5.x whenever possible, 
you might want to consider following this advice.

I know, this is not an answer to your question. It is simply a hint.

Supporting maximum number of keep-alive connections

[Rajeev Jha]

 On 3/17/06, Rajeev Jha [EMAIL PROTECTED] wrote:


 What's your ratio of Apache to Tomcat instances? You may want to look
 into using squid as a reverse proxy to Tomcat, it is very good at
 supporting a huge number of concurrent clients without having to spawn
 a thread or process for each one.

I think that may not be possible in our case. see one aspect of
keep-alive is you keep the pipe open because the same client can
request for more resources. But all such requests are alive for a
finite amount of time only ,so performance is always talked in terms
of through-put.

In our case,the servlet is interfacing to the back-end that sends
async events from time to time. So we really need to hold on to a
thread to receive notifications from the backend. The container spwans
a thread that enters the doGet() of servlet

doGet(){

initial_processing();
  while(pipeOpen) {
 data = pipe.read(); // will block for backend events
 process(data);
outputStream.flush();
}

outputStream.close();
}

Now we can not return this thread to some pool, because I do not know
when the events will arive. And I need to keep the connection open to
push the data + need one thread to block on events.

So I need one thread to server one request. The difference  from
previous case is , our processing of a request is not over in finite
time. we have to keep the same connection open.

I really donot see a way out w/o some support from the container itself.

Jetty has a feature called continuation that is supposed to solve this
issue.But for the moment, I want to try tomcat first. i want to see
how many threads i can support in such a scenario.

I will put a separate mail for that.

Thanks

return (HexUtils.convert(md.digest())) in RealmBase

[Alessandro Colantoni]

Hi All!
I saw that both method Digest(..) and digest(..) in RealmBase return (
HexUtils.convert(md.digest())) and not just
md.digest().toString.

My problem is that user table is maintained by another application developed
in an other technology.
My application uses this table just to authenticate.
The password of user table is encrypted with an algorithm I've been done.
I wrote a MessageDigestSpi for that algorithm, I wrote my provider, I
registered it and everything looks work fine.
Except that of course if I do:
 RealmBase.Digest(myCredentials,myAlgorithm);

I get a result different from doing
MessageDigest md = MessageDigest.getInstance(myAlgorithm);
md.update(myCredentials.getBytes());
md.digest().toString;

but the same result of
 MessageDigest md = MessageDigest.getInstance(myAlgorithm);
 md.update(myCredentials.getBytes());
HexUtils.convert(md.digest())

So the problem is that the other application stores without using the
HexUtils.convert method
but when tomcat authenticates it uses it.

One solution could be write a Realm class that extends the JDBCRealm (the
one I'm using) and overwrite these methods.
But I'm afraid that in different versions of Tomcat (i don't want link to
one) could be different signature of these methods.
There's another solution?
At least avoiding overwriting these very important methods?

And just for curiosity, why HexUtils.convert has been utilized?

Thanks in advance for help and have a nice springtime
Alessandro

RE: return (HexUtils.convert(md.digest())) in RealmBase

[Jay Burgess]

I think this is the right answer:

digest() returns a sequence of bytes.  Depending on the values of the individual
bytes, if you were to try and convert it to String, you can end up with
non-printable characters, etc. 

I'm assuming that HexUtils.convert() turns each 4 bits of each byte into a hex
character, so that you end up with a proper String representation of the digest
that can be sent as part of a URL.

I totally agree. Doing this with http is a lot of unnecessary sit-ups.
However, The existing application runs on a web server   that has
support for resuming/suspending requests and things work out well. we
need to migrate the app to some modern-day container and  trashing the
exisitng application is really not an option.

on the brigther side, hardware is not a big issue with us. if we can
run around 4k threads/box then we are okay. but i do not know if even
that is possible. most of the configurations i had used earlier were
like ~ 100 threads/box.

running two instances of tomcat

[Jim the Standing Bear]

Hi,

Is there a way to run two instances of tomcat 5.5 on the same machine?
Because me and a coworker were developing some webapps using the same node,
but under two different tomcat instances.  We just learned a painful lesson
that as soon as the second instance of tomcat is launched, the first one
dies.  Is there a way to get around the problem? Thank you.

Re: running two instances of tomcat

[Nic Daniau]

That was the case in 4.1 yes, but it doesn't work with 5.5 on Windows
platform, because of the way the service is set up from the nsi scrip (that
you can read from tomcat source). I've written down a procedure to overcome
this and I will post it tomorrow (its on my laptop which I left at the
office tonight). I've tested it on live servers it works fine.

Ideally I hope the guys who write the windows deployer will one day allow
the installer to ask for
1) the name of the servive and not force it to Tomcat5 (whic is the main
issue)
2) use that service name for setting up the reg keys (and not use constants)

Re: running two instances of tomcat

[David Kerber]

I got it working no problem on Windows, running 5.5.12.  Just had to 
mess with the service installation scripts a bit to give each of them 
different names.  A little hassle, but not a big one.

Re: robust Failover, mod_jk

[Vidya TR]

Our application which runs on Apache HTTP Server 2.0.54, TOMCAT 5.0.28 with
mod_jk 1.2.15 connector. In production while our application was running.
Our application had a thread dead Lock hosing up all the users trying to
connect our application. So started investigating the failover setup in
mod_jk. I have two tomcat instances nodeA (active node )  and nodeB
(failover node). When I run my test scenario of a thread dead lock on nodeA
it doesn't seem to be failing over to nodeB. Instead whole site becomes
inaccessible and based on the reply_timeout setting I have I receive a
Service Temporarily Unavailable message. It is very critical for me to
find an answer to this. Is mod_jk the best option? Or should I be
investigating at other High Availability Clustering solutions like Heartbeat
etc...? Please help.  Following is my worker.properties .

RE: running two instances of tomcat

 From: Nic Daniau [mailto:[EMAIL PROTECTED] 
 Subject: Re: running two instances of tomcat
 
 That was the case in 4.1 yes, but it doesn't work with 5.5
 on Windows platform, because of the way the service is set
 up from the nsi scrip (that you can read from tomcat source).

The service.bat script that comes with the .zip download allows you to
specify any arbitrary service name - no special procedures required.
You can use it to install any number of Tomcats running as services.

caldav implementation in webdavServlet

[jirina]

Goog day, my name is George and Im student of IT, and I should create calendar 
server application suporting CalDAV protocol (as an extension to WebDAV to 
publish calendaring data). And I would like to ask, about implementation.

I write it in java (servlet application working on tomcat server), but the 
problem is, that I have not found how to extend WebDAV servlet, to support 
CalDAV extension like MKCALENDAR, REPORT or other CalDAV requests? I tryed to 
find it myself, looking to many documentations or Tomcat's FAQ but I have't 
found, how to implement it.

So, If you know, how to work with servlet container or how to expand 
WebdavServlet to make some interface to recognize CalDAV requests or if you 
know about some useful links I would be very grateful to you.

Re: running two instances of tomcat

[Jim the Standing Bear]

Thanks, Chuck.  I will take a closer look at RUNNING.txt.  However, i still
think there is something else causing our problems..  We installed two
copies of the tomcat code, one running at root, and the other running as a
regular user.  Now, even if the ports were conflicting, it would prevent one
instance from being launched, instead of killing another instance, would
it?  At one time when i was playing with it on a testing platform (also
linux), the launching of the 2nd instance of tomcat 5.5 even killed a
running tomcat 4.1.31! It was incredible :P

 That should be it, just make sure yout get _all_ the ports.  By default,
 there are three for each Tomcat, one more if you enable SSL.  Also, you
 might want to look at RUNNING.txt in the distribution for hints about
 running multiple Tomcats with only one copy of the code installed.

Tomcat 5.5.16 Virtual Hosting Problem

[Vamsidhar]

Hi all:

I have posted for help yesterday, but I think the post was poorly worded. So
I am posting again.

I am using Tomcat 5.5.16 (stand-alone) with JDK 5.0 on Windows XP and trying
to setup virtual hosting (to start with two hosts + localhost). Once I start
the tomcat server, three host folders are being created inside the work
directory.

As expected the localhost host has all the webapps that come with tomcat
5.5.16 installation like examples, etc. The work directory also has two
other host folders test1.mymachine.com and test2.mymachine.com. There is a
single root context for each of these hosts as shown below. The problem is
along with a folder for these root contexts tomcat is also serving up all
folders present in CATALINA_HOME as contexts. This is happening for both
test1.mymachine.com and test2.mymachine.com. Any help is appreciated.

Thanks in advance.

Context path= docBase=c:\websites\test1\webapps\test1
debug=5 reloadable=true crossContext=true

DB resources

/Context

Re: Connector Installation

[Scott Gravenhorst]

More stuff.  I found a tutorial (one of the many) and
in that it was said that the prefork .so file is the
one to copy as mod_jk.so to the directory containing
modules.  It also said to set the chmod permissions to
755.  After I added the loadmodule directive to
httpd.conf, I now get an error when starting Apache:

]# /etc/rc.d/init.d/httpd start
Starting httpd: Syntax error on line 191 of
/etc/httpd/conf/httpd.conf:
Cannot load /etc/httpd/modules/mod_jk.so into server:
/etc/httpd/modules/mod_jk.so: cannot open shared
object file: No such file or directory

What's odd at first is that the directory it's looking
(/etc/httpd/modules) is not where the file is and if I
spell out the entire path to mod_jk.so, I still get
the same error message except that the path to file is
correct.  However, the file does exist! 

Help?

 Greetings from a new guy...
 
 I have Tomcat 5.5 running under FC3.  I would like

 I know tomcat is working because I can display the
 samples via port 8080.  The Apache web server is
 also
 installed and it is working on port 80.
 
 In the docs for the connector, it suggests that it
 is
 better to use the precompiled binaries instead of
 compiling them from source.  I have no problem with
 that and I found the binaries for my platform, they
 are:

jakarta-tomcat-connectors-jk-1.2.14-linux-sles9-x86_64-prefork.so
 and 

jakarta-tomcat-connectors-jk-1.2.14-linux-sles9-x86_64-worker.so
 
 The docs talk about a mod_jk.so, which is not what
 I
 have (by name).  Perhaps I'm supposed to rename one
 of
 these files to mod_jk.so ?  If so, which one and
 what
 happens to the other one?  The docs don't mention a
 pre-fork module (that I can see).

Running webapp as root context

[Ryan Di Francesco]

Hello -
 
I've just finished my first installation of Tomcat 5.5 along with
Meeting Maker.  Right now the URL to access Meeting Maker is
http://localhost/mmwebclient.  As this is the only application this
server will be running, ideally I'd like to configure it so just
accessing http://localhost will direct one to Meeting Maker, instead of
the default Tomcat webpage.  D:\Tomcat 5.5\webapps\mmwebclient is where
the Meeting Maker application resides.  If anyone can provide me with
details on how to do this or point me in the right direction, it would
be greatly appreciated.
 
Thanks in advance for your time and consideration.

 Hello,
 Do you know when the tomcat development group plans on not releasing any new
 patches for Tomcat 4? Does this ever happen? If a bug is found in Tomcat 4
 is it fixed in Tomcat 4 or are we forced to upgrade to Tomcat 5?

I am currently working my way through all reported TC4 bugs (there is
just one left if you ignore the enhancement requests) and back porting
some connector enhancements that should make most of the connector
options in 5.5.x available in 4.1.x. Once this is complete I intend to
do a 4.1.32 release. Unless 4.1.32 has a major problem, it will almost
certainly be security fixes only after that point.

To pre-empt your next question, I am not working to any particular
date for 4.1.32. The job that pays the bills is taking up a lot of
time at present so 4.1.32 will happen when it happens.

Between now and 4.1.32, if a bug is reported against 4.1.x my
intention is that it will get fixed. If a flood of 4.1.x bugs appear
in bugzilla, then all of the above may change.

Problem configuring webapp with Tomcat 5.0.28 on RHE3

[Rachel McConnell]

I've got a web application that runs succesfully on Win/Tomcat 5.0 and 
on RH/resin 2.x.  I am pretty sure my problem is with the container 
configuration.  I need to run several versions of the app and I'd like 
to do this using several different Tomcat instances, with different 
$CATALINA_BASE directories.  (There is an Apache front-end but that 
isn't relevant yet.)


I cannot seem to get the app to start.  I have a directory set up as the 
CATALINA_BASE with the following content (I've left out a couple 
unrelated dirs for simplicity):


base_dir
  apps
myWebAppBaseDir (which contains WEB-INF and so forth)
  conf
Catalina
  localhost
ROOT.xml
context.xml (the default that comes with Tomcat)
server.xml
web.xml (the default that comes with Tomcat)
(other default files: catalina.properties, tomcat-users.xml, etc)
  logs
  temp
  webapps (empty)
  work


I believe the necessary configuration is only in the server.xml and the 
ROOT.xml files, and the rest are OK to use the defaults.  I've pasted 
the server.xml and ROOT.xml files below for reference.  As you'll 
notice, I am attempting to run the app from a directory structure, not 
from a WAR file, and it is intended to run as the root application with 
no context path.


Using the configuration I've currently got (below), I can start Tomcat 
and no errors show up in the logs, although the startup process my app 
normally goes through does not seem to occur (that is, the messages from 
it don't show up).  If I try to hit a page on the server, I get an 
exception (below) that I can't find anywhere on Google nor in this 
list's archives.


I tried configuring the app by placing the content of ROOT.xml into the 
host element of server.xml, as is recommended AGAINST in the Tomcat 
docs.  This produced the same exception.


In all cases I start Tomcat using a script I wrote that sets JAVA_HOME 
and CATALINA_BASE and then calls CATALINA_HOME/bin/catalina.sh (full 
script below).


Any ideas on what to do, or pointers to further research, are much 
appreciated!


Thanks,
Rachel McConnell

You can specify parameters on the various tabs under the servicew app (the

alongside the start option.

RE: overheads on multiple connectors

[Chris Fong]

Thanks for the replies.

 : Where are you getting this 20 connection count from? Those must be
 : currently open connections to clients?

Actually, I am talking about connector (Http Connector) instead of
connection.  

 To the Chris, I personally don't think it is the norm since your
average
 site usually don't get that kind of load. I would start with 2 or 3
and
 scale up as needed.

I have gotten request to separate traffic to multiple ports so that
Network Engineer can manage/debug network traffic easier (by port).  I
totally agree this will make troubleshooting easier, but I am also
afraid there is performance cost in implementing this.

The tomcat instance could get very busy some times with only 1
connector.  (3k+ requests every minute)  Therefore, I am wondering once
I starts having 20 connectors (listening on 20 different ports), will
the performance be affected by a lot.

Thanks,

 Well, it is possible to configure multiple AJP connectors, each

multiple Tomcat realm

Would like to track googlebots, or spiders from site

[Scott Purcell]

Not necessarily a tomcat problem, but I have created a webapp on Tomcat 5.x. I 
would like to be able to track any robot activity in a log file, but not really 
sure where to begin looking for this functionality? If this is possible, is 
there  a debug level that could be used so I could find out what pages it hits, 
etc? Or is this something that needs to be written and tired into the 
container. This is Tomcat standalone, no Apache front end.


If anyone has this knowledge, links, etc. I would certainly appreciate.

Regards
Scott

mod_jk failover loadbalancing doesn't recognize hung tomcat

[Vidya TR]

Our application which runs on Apache HTTP Server 2.0.54, TOMCAT 5.0.28 with
mod_jk 1.2.15 connector. In production while our application was running.
Our application had a thread dead Lock hosing up all the users trying to
connect our application. So started investigating the failover setup in
mod_jk. I have two tomcat instances nodeA (active node )  and nodeB
(failover node). When I run my test scenario of a thread dead lock on nodeA
it doesn't seem to be failing over to nodeB. Instead whole site becomes
inaccessible and based on the reply_timeout setting I have I receive a
Service Temporarily Unavailable message. It is very critical for me to
find an answer to this. Is mod_jk the best option? Or should I be
investigating at other High Availability Clustering solutions like Heartbeat
etc...? Please help.  Following is my worker.properties .

Re: overheads on multiple connectors

[Long]

 To the Chris, I personally don't think it is the norm since your
average
 site usually don't get that kind of load. I would start with 2 or 3
and
 scale up as needed.

I have gotten request to separate traffic to multiple ports so that
Network Engineer can manage/debug network traffic easier (by port).  I
totally agree this will make troubleshooting easier, but I am also
afraid there is performance cost in implementing this.

 Chris, I think it is fair to say each connector instance will take up
 a finite amount of computing resources so the more you have
 they will push the server towards its upper limit. Whatever that
 might be depends on CPU speed and RAM.


The tomcat instance could get very busy some times with only 1
connector.  (3k+ requests every minute)  Therefore, I am wondering once
I starts having 20 connectors (listening on 20 different ports), will
the performance be affected by a lot.

 Well 3000 / 60 is 50 requests per second. If you know how long
 it takes to service a request then you are in a better position to
 tackle the performance issue.

 Let's assume, conservatively, your server can do 10 per second.
 Then having the load balancer with 5 workers (linked to 5 connectors)
 should cover your situation. So having 20 might be a bit excessive at
 this point.
 
 Note that workers don't have to link to a local tomcat. If you find
 that your server is maxing out, you can add another server to scale up
 further.

SSL handshake times out on Tomcat 5.5

[Aust, Christian]

Hi,

although I've read all the docs and FAQs I could find, I can't get Tomcat 
5.5.15 to do SSL on Windows with SUN JDK 1.5.

I've imported the keys according to the docs, starting with the root CA cert 
and going all the way up until the cert that matches my key request. Then I've 
copied the keystore file keystore into CATALINA_HOME and configured Tomcat 
like such:

!-- Define a SSL HTTP/1.1 Connector on port 443 --
Connector port=443 maxHttpHeaderSize=8192
   maxThreads=150 minSpareThreads=25 maxSpareThreads=75
   enableLookups=false disableUploadTimeout=true
   acceptCount=100 debug=99
   scheme=https secure=true clientAuth=false sslProtocol=TLS
   keystoreFile=keystore keystorePass=changeit
/

All environment variables are set, JAVA_HOME plus CATALINA_HOME pointing to the 
right directories. When I start Tomcat, there's nothing special in the logs. 
Pointing a browser to https://localhost/ just times out. Doing the same using 
the OpenSSL tool gives me

$ openssl s_client -connect localhost:443 -showcerts -state
CONNECTED(0003)
SSL_connect:before/connect initialization
SSL_connect:SSLv2/v3 write client hello A
2644:error:140790E5:SSL routines:SSL23_WRITE:ssl handshake 
failure:s23_lib.c:188:

Interesting point: Pointing the browser to http://localhost:443/ works. Since I 
don't find anything in the logs, I'm lost. Remaining issues are:

1) Should I import the server certificate under the alias tomcat oder the 
name of the host? There's different documentation about this.

2) Can I increase logging somehow, to see what's going on inside the SSL 
factory/connector?

Any help is appreciated...

Kind regards

Realm defined within my webapp

[Dustin Sallings]

	I have several webapps I am trying to bring over from Resin that  
make use of various types of authentication that needs to live solely  
within my webapp (I may have multiple deployed instances of one with  
different versions, for example).


	I have attempted to add it to META-INF/context.xml in my web  
application, but I get a ClassNotFoundException when the app starts up.


	I would think it'd be common for applications to have code to  
perform their own authentication.  Is this possible?

Re: Running webapp as root context

[Per Johnsson]

Hi!
I think the easiest way is to put all the contents in your folder 
mmwebclient in the webapps/ROOT. Not put the whole folder just the 
contents.

Running webapp as root context






Hello -
 
I've just finished my first installation of Tomcat 5.5 along with
Meeting Maker.  Right now the URL to access Meeting Maker is
http://localhost/mmwebclient.  As this is the only application this
server will be running, ideally I'd like to configure it so just
accessing http://localhost will direct one to Meeting Maker, instead of
the default Tomcat webpage.  D:\Tomcat 5.5\webapps\mmwebclient is where
the Meeting Maker application resides.  If anyone can provide me with
details on how to do this or point me in the right direction, it would
be greatly appreciated.
 
Thanks in advance for your time and consideration.
