JDBC driver: Method not implemented

I got this error while writing some code ...

This method is not yet implemented.
at org.postgresql.Driver.notImplemented(Driver.java:440)
at
org.postgresql.jdbc2.ResultSetMetaData.getColumnClassName(ResultSetMetaData.java:476)

I guess this means that not all of the MetaData methods or implemented
yet in the jdbc2 driver?

The reason I ask is that I have a column of type date and Java does not
seem to recognize it and gives it a Class type of null ...

Does Java have trouble recognizing pg's date type as a date Class?

I use ResultSet.getObject() to load in my data into a TableModel and
this method to retrieve what Class a particular column is:

public Class getColumnClass(int col) {
Class c = null;
try {c = getValueAt(0, col).getClass();}
catch (Exception e) {}
if (c == null) {
System.out.println("COL " + col + " was NULL");
try {
c = Class.forName("java.lang.String");
}
catch (ClassNotFoundException e) {}
}
return c;
}

For column of type date, the reported Class is always null ... this is a
small problem for me :)
