The CustomDatumExample.java only works if the Employee object has 2 attributes.

Question

The CustomDatumExample.java only works
if the Employee object has 2 attributes -
(EmpName and EmpNo). If I try to add
another attribute to the Employee object I get java.lang.ArrayIndexOutOfBoundsException: 2 on the getAttr3 method.
Anyone know why? Thanks.
Employee object
CREATE TYPE employee AS OBJECT
(empname VARCHAR2(50), empno INTEGER,
attr3 VARCHAR2(50));
Custom object class
public class Employee implements CustomDatum, CustomDatumFactory
public static final String SQLNAME = "EMPLOYEE";
public static final int SQLTYPECODE = OracleTypes.STRUCT;
MutableStruct _struct;
static int[] _sqlType =
12, 4
static CustomDatumFactory[] _factory = new CustomDatumFactory[3];
static final Employee _EmployeeFactory = new Employee();
public static CustomDatumFactory getFactory()
return _EmployeeFactory;
/* constructor */
public Employee()
struct = new MutableStruct(new Object[3], sqlType, _factory);
/* CustomDatum interface */
public Datum toDatum(OracleConnection c) throws SQLException
return struct.toDatum(c, SQL_NAME);
/* CustomDatumFactory interface */
public CustomDatum create(Datum d, int sqlType) throws SQLException
if (d == null) return null;
Employee o = new Employee();
o._struct = new MutableStruct((STRUCT) d, sqlType, factory);
return o;
/* accessor methods */
public String getEmpname() throws SQLException
{ return (String) _struct.getAttribute(0); }
public void setEmpname(String empname) throws SQLException
{ _struct.setAttribute(0, empname); }
public Integer getEmpno() throws SQLException
{ return (Integer) _struct.getAttribute(1); }
public void setEmpno(Integer empno) throws SQLException
{ _struct.setAttribute(1, empno); }
public String getAttr3() throws SQLException
{ return (String) _struct.getAttribute(2); }
public void setAttr3(String attr3) throws SQLException
{ _struct.setAttribute(2, attr3); }
}

You also need to add an appropriate element to the _sqlType array.
In practice, it is easiest to have JPublisher regenerate the CustomDatum class when you have changed your object type definition:
jpub -user=scott/tiger -sql=EMPLOYEE:Employee
