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
