Anyone run into mapping an unsigned BIGINT? I don't see how its possible
in Java?

Judging from the exception the driver is throwing, I don't think either is
possible. Remember, Java doesn't do unsigned. All the JDBC driver seems to
know is that its a BIGINT. It has no concept of UNSIGNED BIGINT.

Assuming you are using MySQL...

Connector/J documentation states that you should use
ResultSet.getObject(), and then cast to java.math.BigInteger.

So in iBATIS, you should set your bean property type to Object, and
then cast it to BigInteger after the result is returned from iBATIS.
Or, you could create a type handler that would do this within the
iBATIS processing.

Why can't you use Long or long?
