Ok Todd,  So I need to bind to the libraries of both v1.5 and v1.6.  I now 
have the Ant build defined and getting the warning about the different 
compliers.

I will play and sort this out.

thanks for the assist.

regards,

Kevin

Yes, unfortunately.  You'll want to take a look at the ant build script
- it has two different compile steps.  The first handles the pre-JDBC4
code baseline (which, as noted by the error message above, does not
implement the new-to-JDBC4 methods), and a second uses a Java 6.0+
compiler to handle the JDBC-specific classes.  Within C/J itself, the
driver does a check to see if we're running in a JDBC4-enabled JVM or
not, and if so, uses the classes in the com.mysql.jdbc.JDBC4* classes.

In short, use the ant build script to compile C/J (and you will need to
have a both a pre-6.0 and 6.0+ Java compiler).

Best regards,
