  Hi Dale,
 I had a similar error 'Could not create a DBCP pool' when I first installed
 XEM on a Suse linux box, while all the rest seemed OK.
 So I tried to look inside Tomcat installation: open .../conf/server.xml  and
 go to the line that starts with
 <Connector port="8080" protocol ="HTTP/1.1" .....
 Comment all this section.
 Immediately after starts a section that is commented by default that starts
 witn the line
 <Connector executor="tomcatThreadPool"
 Make this section live and add as suggested somewhere in the tutorial the
 line
 URIEncoding="UTF-8"
 Restart everything.
 It worked for me, even if I don't really know why (I am not a programmer or
 Java/Tomcat guru).
 Hope that can help you, too

I did the following:
    <!-- DMA20110804 Commented out as suggested by AngeloG-->
    <!-- A "Connector" represents an endpoint by which requests are received
         and responses are returned. Documentation at :
         Java HTTP Connector: /docs/config/http.html (blocking & non-blocking)
         Java AJP  Connector: /docs/config/ajp.html
         APR (HTTP/AJP) Connector: /docs/apr.html
         Define a non-SSL HTTP/1.1 Connector on port 8080
    <Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               URIEncoding="UTF-8"
               redirectPort="8443" />
    -->
    <!-- A "Connector" using the shared thread pool-->
    <!-- DMA20110804 Uncommented and added URIEncoding as suggested by AngeloG-->
    <Connector executor="tomcatThreadPool"
               port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               URIEncoding="UTF-8"
               redirectPort="8443" />
Rebooted the VM even, But I still get:

not initialize main XWiki context
