Problems Installing Jahia: JetSpeedEngineConstants not found!

Hi,

I am having a problem getting jahia running on my Tomcat server. I've
using mod_jk
to bridge between Apache Tomcat server and Apache httpd -- it works
fine with other
web applicaitons I've deployed thusfar. I've the following host context in my
tomcat/conf/server.xml. My jahia deployment base is /var/www/myhost/jahia, all
the directories are owned by a tomcat user/group accordingly and have
755 permission
(for now). I am trying to run The Jahia Community Edition, latest version, 5.0
(jahia5.0_CE_r14784.tar.gz)


  <Connector address="127.0.0.1"
    port="8009"
    minProcessors="5"
    maxProcessors="75"
    enableLookups="false"
    protocol="AJP/1.3"/>

   <Engine name="appserver">



    <Host        name = "bloo.ms"
              appBase = "/var/www/myhost/"
           autoDeploy = "true"
      deployOnStartup = "true"
            upackWARs = "false"
            deployXML = "true">


              <Valve className="org.apache.catalina.valves.AccessLogValve"
              directory="logs"  prefix="myhost_jahia_access_log." suffix=".txt"
              pattern="common" resolveHosts="true"/>

       <Context path=""
                docBase="jahia"
                reloadable="true">

         <WatchedResource>WEB-INF/web.xml</WatchedResource>

       </Context>

    </Host>

   </Engine>
   ...


The following is the snipet of tomcat/logs/catalina.out when I try to
start Tomcat
server. The line that is throwing an exception is `Caused by:
java.lang.NoClassDefFoundError:
org/apache/jetspeed/engine/JetspeedEngineConstants' so obviously
Tomcat classloader is failing to load this particular class for this
application. I've `jar tfv' the
entire jahia/WEB-INF/lib/*.jar looking for this class but couldn't
find any. And
why is jahia trying to create a particular brand of database before the inital
installation jahia run up? I thought I would be able to select my
database during
the installation (obviously I can't get the jahia application to work so I don't
know at what point of the installation I'll be able to create appropriate tables
and what not).

And yes, that's what Tomcat writes to catalina.out and nothing more. After that
it just seems to hang and I don't get my shell prompt back. Any ideas?
