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?
