    Thank you for all your work on what looks like a great product!

    I just completed the install process on our server and running into what I assume is a simple issue. I have searched Google, your wiki site, this SF site and have not found the answer.

    - Server
    CentOS 4.4 i686 (WHM / cPanel)

    I created a domain specifically for the use of this software, I do not as much car if the software is available to other domains on the server.. I have a fixed IP for the domain. When I start dimdim and get status I see the service is running, but when I go to the URL/dimdim/ I get an error 404. My goal is to access all dimdim services / functions via http://www. GatherCast.com/ (or dimdim/ if needed).

    Do I have to install some html in a subdirectory, do I have to add an Alias in httpd.conf? Do I have to create an index file for the url I am going to be using? Are there notes on how to customize / integrate the software to a domain? Included below are my configuration file information.

    Thank you in advance for your assistance.

             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 1.0.2 or
               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.

                 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

                 clusterName = 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

                 mcastBindAddress = 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

      It looks like you have Dimdim running off of port 80? I would try changing the Dimdim port numbers to something like 8050 it may be having issues with other programs running on that port. You would then access it by typing http://www.yourdomain.com:8050/dimdim.

      Thank you very much - I am not getting an error 404 from Tomcat, and not Apache:

      type Status report
      message /dimdim/

      UPDATE:

      I changed the port to 8080 and received the 404 error from Tomcat (see previous post). I then changed the port to 8050 and now the system appears to be working. Does this make sense ? How do I run the software on port 80, and what would be causing this not to work (apache setting, server setting, etc) ?

      Thank you,

      Scott
