java.sql.Types problem

Howdy,
I'm getting a java.sql.Types value of 16 for varchar field instead of the 12 
I expected.

I'm also getting a 15 for timestamp field instead of 93.

I don't have a clue as to why they are returning those values, does 
anyone have a hint?

Platform: jdk1.1, PostgreSQL 6.5.1

Where can I get the source for the jdbc driver; I seem to only have the 
class files.
