You did not say which version of Tomcat you were using, or what OS. It
appears you are using Windows - check the settings on any software
firewall
you may have configured as this may be preventing access. Can you ping
from
the other machine to your Tomcat server?

Subject: apache Tomcat webserver problem
Hello.
<p>I have set up tomcat's service catalina to have the default host
192.168.15.100 and have also changed the virtual host to be the same.
Also
added a context element with the sample app.
Now when I try to access the app using the following url
http://192.168.15.100:8080/sample from my machine it works fine.
But if i go to another machine, I am not able to access the website.
I get
the page cannot be displayed error. Followed by the usual ramblings
ending
with cannot find the server.
My question is how do you set up TomCat to be the webserver and what is
going on ..? Why is it not recognizing this address from another machine
while it does so from my machine?
Anyone who knows this will be great.
thank you
Here is my server.xml file

<!-- A "Connector" represents an endpoint by which requests are

By default, a non-SSL HTTP/1.1 Connector is established on port
8080.
You can also enable an SSL HTTP/1.1 Connector on port 8443 by
following the instructions below and uncommenting the second
Connector
entry. SSL support requires the following steps (see the SSL
Config
HOWTO in the Tomcat 5 documentation bundle for more detailed
instructions):
* If your JDK version 1.3 or prior, download and install JSSE
1.0.2or
later, and put the JAR files into "$JAVA_HOME/jre/lib/ext".
* Execute:
%JAVA_HOME%\bin\keytool -genkey -alias tomcat -keyalg RSA
(Windows)
$JAVA_HOME/bin/keytool -genkey -alias tomcat -keyalg RSA
(Unix)
with a password value of "changeit" for both the certificate
and
the keystore itself.
By default, DNS lookups are enabled when a web application
calls
request.getRemoteHost (). This can have an adverse impact on
performance, so you can disable it by setting the
"enableLookups" attribute to "false". When DNS lookups are
disabled,
request.getRemoteHost () will return the String version of the
IP address of the remote client.

<!-- Defines a cluster for this node,
By defining this element, means that every manager will be
changed.
So when running a cluster, only make sure that you have
webapps
in there
that need to be clustered and remove the other ones.
A cluster has the following parameters:
className = the fully qualified name of the cluster class
name = a descriptive name for your cluster, can be anything
mcastAddr = the multicast address, has to be the same
for all
the nodes
mcastPort = the multicast port, has to be the same for all
the
nodes
mcastBindAddr = bind the multicast socket to a specific
address
mcastTTL = the multicast TTL if you want to limit your
broadcast
mcastSoTimeout = the multicast readtimeout
mcastFrequency = the number of milliseconds in between
sending
a "I'm alive" heartbeat
mcastDropTime = the number a milliseconds before a node is
considered "dead" if no heartbeat is received
tcpThreadCount = the number of threads to handle incoming
replication requests, optimal would be the same amount of threads as
nodes
tcpListenAddress = the listen address (bind address) for
TCP
cluster request on this host,
in case of multiple ethernet cards.
auto means that address becomes
InetAddress.getLocalHost
().getHostAddress()
tcpListenPort = the tcp listen port
tcpSelectorTimeout = the timeout (ms) for the
Selector.select
()
method in case the OS
has a wakup bug in java.nio . Set to 0
for
no timeout
printToScreen = true means that managers will also print to
std.out
expireSessionsOnShutdown = true means that
useDirtyFlag = true means that we only replicate a session
after setAttribute,removeAttribute has been called.
false means to replicate the session after
each
request.
false means that replication would work for
the
following piece of code: (only for SimpleTcpReplicationManager)
<%
HashMap map =
(HashMap)session.getAttribute("map");
map.put("key","value");
%>
replicationMode = can be either 'pooled', 'synchronous' or
'asynchronous'.
* Pooled means that the replication
happens
using several sockets in a synchronous way. Ie, the data gets
replicated,
then the request return. This is the same as the 'synchronous' setting
except it uses a pool of sockets, hence it is multithreaded. This is the
fastest and safest configuration. To use this, also increase the nr
of tcp
threads that you have dealing with replication.
* Synchronous means that the thread that
executes the request, is also the
thread the replicates the data to the
other
nodes, and will not return until all
nodes have received the information.
* Asynchronous means that there is a
specific
'sender' thread for each cluster node,
so the request thread will queue the
replication request into a "smart" queue,
and then return to the client.
The "smart" queue is a queue where when a
session is added to the queue, and the same session
already exists in the queue from a
previous
request, that session will be replaced
in the queue instead of replicating two
requests. This almost never happens, unless there is a
large network delay.
-->
<!--
When configuring for clustering, you also add in a valve to
catch all the requests
coming in, at the end of the request, the session may or may
not
be replicated.
A session is replicated if and only if all the conditions
are
met:
1. useDirtyFlag is true or setAttribute or
removeAttribute has
been called AND
2. a session exists (has been created)
3. the request is not trapped by the "filter" attribute
The filter attribute is to filter out requests that could
not
modify the session,
hence we don't replicate the session after the end of this
request.
The filter is negative, ie, anything you put in the filter,
you
mean to filter out,
ie, no replication will be done on requests that match
one of
the filters.
The filter attribute is delimited by ;, so you can't escape
out
; even if you wanted to.
filter=".*\.gif;.*\.js;" means that we will not replicate
the
session after requests with the URI
ending with .gif and .js are intercepted.
The deployer element can be used to deploy apps cluster
wide.
Currently the deployment only deploys/undeploys to working
members in the cluster
so no WARs are copied upons startup of a broken node.
The deployer watches a directory (watchDir) for WAR files
when
watchEnabled="true"
When a new war file is added the war gets deployed to the
local
instance,
and then deployed to the other instances in the cluster.
When a war file is deleted from the watchDir the war is
undeployed locally
and cluster wide
