Subject Re: Doc question - Upgrading a database
Date Fri, 29 Sep 2006 01:13:05 GMT
Hi Laura,

Sorry missed your mail.
Yes I agree the step of manually updating the CLASSPATH to the latest 
jars will be useful.  Worthwhile
to mention  that the Derby version should be verified once the CLASSPATH 
is updated to make sure
no other older versions of Derby jars exist.

Regards,
Rajesh
