Problem with getObjet

Hello,

I have the following code:

try
{
rs = stat.executeQuery(SQL);
}
catch (SQLException ex)
{
throw ex;
}

while (rs.next())
{
sim.addNoeud(rs.getObject(1), rs.getObject(2), rs.getByte(3));
}

where stat is a Statement, rs a ResultSet and SQL my SQL query.
My problem is that the rs.getObject commands return null. But if I use
rs.getString() it returns the correct value (ie a string that is not
null)...

I am wondering if this means that I can't use the getObject to get a
String ??? I used to do it with Oracle database....
The program used to work with Oracle, so I need to know the changes I
have to do to make it work under Postgres.
Thanks for your help.
