Hi Doug,

Can you post the stack trace from the exception?
Are you sure Hibernate is mapping the column to the right column type?

Regarding the Derby version, one way to figure it out is invoke the 
command below with at least one of the Derby jars (i.e. derby.jar, 
derbyclient.jar etc) in the classpath:
java -cp <yourclasspath> org.apache.derby.tools.sysinfo
       		 or potentially
java -jar derbyrun.jar sysinfo

I don't remember exactly, but I think you can use JDBC meta data calls 
as well. You can also look at some files inside one of the jars, for 
instance the manifest file, and if you start ij the version is printed 
(not the full version, i.e. only 10.5).
