Installing the calendar system is fairly simple.

1) Setup (or have access to) MySQL version 3.3 or later on any platform.  Create
   a database and login for the calendar application to use.

2) Run the calendar.sql script against your database to create the tables.

3) Copy the "calendar" folder to your web server in an appropriate location.
   If you're already running Apache or some other web server to host sites, the
   "calendar" folder does not need to be under an existing site.

4) Setup (or have access to) Tomcat version 5.5 or later.  (Actually, this
   package works just fine under Tomcat 4.1 or later, but the instructions
   below on editing the configuration files are 5.5-specific.  If you're
   comfortable configuring Tomcat, making the configuration below work on 4.1
   or 5.0 shouldn't be difficult.)

5) Setup Tomcat to host the "calendar" folder as a webapp.  If you're already
   familiar with Tomcat, skip to step 6.  If you've never used Tomcat before
   or if it's only installed for this one application, the following instructions
   should get you going.  If you have problems, see:
        http://jakarta.apache.org/tomcat/tomcat-5.5-doc/config/index.html

   a) Rename the "server.xml" file in Tomcat's "conf" folder to something else
      as a backup (e.g. server.xml.old).

   b) Create a new "server.xml" file with the following contents:
................................................................................
<Server port="8005" shutdown="SHUTDOWN">
  <GlobalNamingResources>
  <Resource name="UserDatabase" auth="Container"
            type="org.apache.catalina.UserDatabase"
     description="User database that can be updated and saved"
         factory="org.apache.catalina.users.MemoryUserDatabaseFactory"
        pathname="conf/tomcat-users.xml" />
  </GlobalNamingResources>

  <Service name="Catalina">
    <Connector port="#SERVER_PORT#" address="#SERVER_IP_ADDRESS#" className="org.apache.coyote.tomcat5.CoyoteConnector" compression="on" />

    <Engine name="Catalina" defaultHost="localhost">

      <Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="UserDatabase" />

      <Host appBase="/var/www/html" name="localhost" />

      <Host appBase="#CALENDAR_FOLDER_PATH#" name="#WEBSITE_NAME#">
        <Logger className="org.apache.catalina.logger.FileLogger" prefix="tomcat." suffix=".txt" timestamp="true" directory="#SYSTEM_LOG_DIRECTORY#"/>
        <Valve className="org.apache.catalina.valves.AccessLogValve" pattern="combined" directory="#WEBSITE_LOG_DIRECTORY#" fileDateFormat="yyyy-MM-dd" prefix="tomcat." suffix=".txt"/>
      </Host>
    </Engine>
  </Service>
</Server>
................................................................................
     Replace the markers in the above text with appropriate values.
     Specifically:
       #SERVER_IP_ADDRESS# should be replaced with your web server's IP address.
       #WEBSITE_NAME# should be replaced with your website address (e.g.
         www.example.com).
       #CALENDAR_FOLDER_PATH# should be replaced with the full path to the
         "calendar" folder you copied to your web server in step 4.
       #SYSTEM_LOG_DIRECTORY# should be replaced with the full path to a folder
         where you'd like Tomcat to put its system-level log file.  This is the
         file where Tomcat status and error messages will appear.
       #WEBSITE_LOG_DIRECTORY# should be replaced with the full path to a folder
         where you'd like Tomcat to put the website usage log.  This is the file
         where the record of every hit to the website will be recorded.
       #SERVER_PORT# should be replaced with the port number you want to run
         your Tomcat server on.  Normally, this should be port 80 but if you're
         already running another webserver (Apache, IIS, etc), you'll need to
         use another port such as 8080.

   c) If Tomcat will be serving requests on its own and you don't need to
      configure another web server to proxy connections to it, skip to step 6.

   d) If the other web server is not Apache, you're on your own.  Sorry.

   e) If you are already running Apache and you want Apache to proxy requests to
      Tomcat so it appears everything is running on one site with no port
      numbers, add the following line to server.xml, just below the
      "<Connector..." line (i.e. there will be two "<Connector..." lines):
................................................................................
    <Connector port="#PROXY_PORT#" proxyName="#WEBSITE_NAME#" proxyPort="#SERVER_PORT#"/>
................................................................................
     Replace the markers in the above text with appropriate values.
     Specifically:
       #PROXY_PORT# should be some other port that's not already in use on your
         web server.  Try 8081.  Remember this value -- you'll need it when you
         configure Apache.
       #WEBSITE_NAME# should be replaced with your website address (e.g.
         www.example.com).  This should be the same address you used in step 6b.
       #SERVER_PORT# should be replaced with the port you chose in step 6b.

   f) Reconfigure Apache to proxy connections to Tomcat using mod_proxy.  See:
        http://httpd.apache.org/docs-2.0/mod/mod_proxy.html

6) If it doesn't already exist, create a folder named "Catalina" (note the
   capital "C") in Tomcat's "conf" folder.

7) Inside the "Catalina" folder, create a folder named with the name of your
   website (e.g. "www.example.com").  This should be the same name you used in
   step 5b.

8) Decide where on your website you want the calendar application to appear.
   If you want it to be at the root of your site, create a text file named
   "ROOT.xml" inside the website folder.  If you want it to appear in a folder
   (e.g. "http://www.example.com/jonescalendar/"), create an XML file with the
   name of the directory you want (e.g. "jonescalendar.XML").  The case of the
   folder name is important.

9) In the new XML file, put the following text:
................................................................................
<Context crossContext="true" displayName="Calendar" path="/#WEBSITE_FOLDER_NAME#" docBase="#CALENDAR_FOLDER_PATH#" cookies="false">
  <Resource
    name="jdbc/calendar"
    auth="Container"
    type="javax.sql.DataSource"
    username="#MYSQL_USERNAME#"
    password="#MYSQL_PASSWORD#"
    driverClassName="com.mysql.jdbc.Driver"
    url="jdbc:mysql://#MYSQL_SERVER_NAME#:#MYSQL_PORT_NUMBER#/#MYSQL_DATABASE_NAME#?autoReconnect=true"
    maxWait="10000"
    maxIdle="30"
    maxActive="100"/>
</Context>
................................................................................
    Replace the markers in the above text with appropriate values.
    Specifically:
      #WEBSITE_FOLDER_NAME# should be replaced with nothing if the calendar
        is to appear at the root of your website.  Otherwise, it should be
        replaced with the name of the folder (the same name you gave the XML
        file).
      #CALENDAR_FOLDER_PATH# should be replaced with the full path to the
        "calendar" folder you copied to your web server in step 4.
      #MYSQL_USERNAME# should be replaced with the login name for the calendar
        database on your MySQL server.
      #MYSQL_PASSWORD# should be replaced with the password for the calendar
        database on your MySQL server.
      #MYSQL_SERVER_NAME# should be replaced with the name of your MySQL
        server.  If your MySQL server is running on the web server, this should
        be "localhost".
      #MYSQL_PORT_NUMBER# should be replaced with the port number your MySQL
        server uses.  If you don't know what this is, use 3306.
      #MYSQL_DATABASE_NAME# should be replaced with the name of the calendar
        database on your MySQL server.

10) Install the JavaMail API package from:
      http://java.sun.com/products/javamail/
    The JAR file can be placed in Tomcat's "common/lib" folder (which makes it
    available to every Tomcat application) or in the calendar application's
    "WEB-INF/lib" folder (which only makes it available to the calendar
    application).

    (The JavaMail file cannot be distributed with the Calendar package due to
    Sun's licensing policies.  If you find this annoying, feel free to join the
    millions who have already complained to Sun about it.)

11) Install the JavaBeans Activation Framework package from:
      http://java.sun.com/products/javabeans/jaf/index.jsp
    The JAR file can be placed in Tomcat's "common/lib" folder (which makes it
    available to every Tomcat application) or in the calendar application's
    "WEB-INF/lib" folder (which only makes it available to the calendar
    application).

    (The JavaBeans Activation Framework file cannot be distributed with the
    Calendar package due to Sun's licensing policies.  If you find this
    annoying, feel free to join the millions who have already complained to Sun
    about it.)

12) Edit the "calendar.properties" file under the calendar application's
    "WEB-INF" folder to provide appropriate values for the application settings
    The values have comments next to them to indicate their purpose.

13) (Re)Start Tomcat (and restart Apache if necessary) and hit the calendar site
    using your web browser.  If everything is working correctly, you should see
    a blank calendar grid for the current month.  If not, check for errors in
    the Apache and Tomcat log files.

14) Click the "Edit calendar" link in the upper-right corner of the calendar.
    To login, use:
      Email address: admin@example.com
      Password: admin
    When you login, you must change that email address and/or password before
    you can proceed.  This is for your own good.

15) That's it.  Start populating your calendar with events and info.
