I ran across a similar problem, and was informed that MySQL was configured so
that host "localhost" and user "root" would not work together.  Instead, when
I ran configure, I used the name of the computer as host.  I'm sorry I don't
know enough to explain the details of MySQL, but try running configure again
using  "rocky.umeoce.maine.edu" as MySQL host and see if that works.

LAS v6 does use both the Apache and Tomcat servers, the latter being used
specifically as the Java Servlet container.  As far as the details go, I know
as much about this as I do MySQL, someone else please take over.
