JDBC not accepting null Oracle object parameters to PL/SQL procedures

I am calling an Oracle Stored Procedure (Oracle 9i), passing in Oracle defined objects.
It is possible that these objects are null. I am using JPublisher to generate the java objects directly based upon the Oracle Object definitions.
Problem is that I am getting the following exception
java.sql.SQLException: Invalid column type

Here is an example of one such parameter
if (convFeeConsPayee == null ){
  stmt.setNull(7, java.sql.Types.STRUCT);
}
else {
  stmt.setObject(7, convFeeConsPayee);
}

>>stmt.setNull(7, java.sql.Types.STRUCT);

Is Struct the correct column type?

Kind of :)
The Java object representing the Oracle object definition implements wraps a MutableStruct but it is not strictly one itself.
These objects are also out parameters and the following works as expected
stmt.registerOutParameter(1, java.sql.Types.STRUCT, SITE_TYPE._SQL_NAME);
where SITE_TYPE._SQL_NAME just resolves to the real Oracle oject name

What if you try: stmt.setNull ( 7,  java.sql.Types.NULL ) ;

Try

stmt.setNull ( 7,  java.sql.Types.OTHER ) ;

The solution is to specifiy it as a STRUCT and to specify the sqlType as well
e.g.
stmt.setNull(7, java.sql.Types.STRUCT, CONSUMER_PAYEE_TYPE._SQL_NAME);

Thanks
