JDBC: Using Serialize.create()

Hi, 

has anyone been successfull in using public static void
create(Connection con, Object o) in Class Serialize to create a
postgresql table. 

I have a simple class Atom that has an int and a float, that's it. 
When I do a

Atom a = new Atom();
postgresql.Connection pc = (postgresql.Connection)db;
System.out.println(pc);
System.out.println(a);
Serialize.create(pc, a);

then I get 

postgresql.jdbc2.Connection@25ab41

nmrshiftdb.Atom@e3e60

java.lang.NullPointerException


The Connection db is valid since I can create tables using regular SQL
statements. 
Also, as one can see, my instance of Atom is not null.

Any hints? 

TIA, 

Chris
