connection..
This is a WORD document !!!!
The error message is quite clear:
java.lang.ClassNotFoundException: com.mysql.ODBC.Driver
ClassNotFoundException => not on classpath.
and it says "ODBC" - not "jdbc".
Try googling for error messages - there are lots of hits.
You are using the out-of-date Jena RDB storage. It is no long part of
the codebase or the distribution.

That depends.
What is the relational database going to be used for or by?
Would using Jena's SDB -- which stores RDF in a SQL database do the
job?
Do you already know how to use a database from Java?
Who defines what the table layout is -- you, or someone else?
