Two ideas:

1. If you don't include the variable in your insert statement, doesn't
the default value happen automatically? In this case
INSERT INTO TEST (varcharfield1) VALUES (?), should result in
varcharfield2 getting its default value.

2. This is a longer shot ...

does  this work?

INSERT INTO TEST (varcharfield1, varcharfield2) VALUES (?, DEFAULT)
