After getting fuseki with SDB working yesterday I check it this morning and got 
a 500 Server Error, with a  SQLException in executing SQL statement message.

This appears to be the same problem I was trying to fix by migrating from 
Joseki to Fuseki.  After a bit of searching I came across this thread 
(http://tech.groups.yahoo.com/group/jena-dev/message/35766) which describes the 
same problem when using Joseki.  The link I've included shows a class for doing 
database connection pooling but it appears to be a standalone class and there 
isn't any information about where it might be hooked into SDB.  I've been using 
database connection pooling for a long time and have had better success with 
the C3p0 db connection pooling library and have it wired into a Tomcat servlet 
container but it seems to me a ConnectionPooling class could be wired into SDB, 
but it would be nice if it pulled in the database connection values from the 
config file instead of hardcoding them in the java class as the URL shown above 
does.

I've seen numerous references to connection management and connection pooling 
with SDB but haven't seen any sort of recipe for how to put it all together.
