How to Map OraData to Java

Question

Hi
I'm trying to Map Oracle data to Java. Call some procedure which return nested table of object. I'm using thin driver. Here is my code.
type test1 as object
(data1 VARCHAR2(40),data2 varchar2(30));
type test2 IS TABLE OF test1;
procedure test (ven2 out test2);
Test Class:
OracleCallableStatement cstmt = (OracleCallableStatement)con.prepareCall("call Test(?)");
cstmt.registerOutParameter(1,OracleTypes.ARRAY,"TEST2");
cstmt.execute();
ARRAY array = cstmt.getARRAY(1);
Map map = con.getTypeMap();
map.put("SchemaName.TEST1", Class.forName(Test1Type.class.getName()));
// Retrieve array elements
Object[] myObjects = (Object[]) array.getArray();
// Each array element is mapped to MyObj object.
for (int i=0; i<myObjects.length; i++)
Test1Type obj = (Test1Type)myObjects;
Test1Type Class:
import java.sql.SQLException;
import oracle.jdbc.OracleConnection;
import oracle.jdbc.OracleTypes;
import java.sql.SQLData;
import java.sql.SQLInput;
import java.sql.SQLOutput;
import oracle.sql.STRUCT;
import oracle.sql.ARRAY;
import oracle.jpub.runtime.MutableStruct;
public class Test1Type implements SQLData {
public static final String SQLNAME = "SY_VCC.TEST2";
public static final int SQLTYPECODE = OracleTypes.ARRAY;
private String data1;
private String data2;
/* constructor */
public Test1Type ()
public void readSQL(SQLInput stream, String type)
throws SQLException
setData1(stream.readString());
setData2(stream.readString());
public void writeSQL(SQLOutput stream)
throws SQLException
stream.writeString(getData1());
stream.writeString(getData2());
public String getSQLTypeName() throws SQLException
return SQLNAME;
/* accessor methods */
public String getData1()
{ return data1; }
public void setData1(String xdata1)
{ data1 = xdata1; }
public String getData2()
{ return data2; }
public void setData2(String xdata2)
{ data2 = xdata2; }
The Test Class Throws the Exception
java.lang.ClassCastException: oracle.sql.STRUCT
Thanks in advance

This construction is working well, but I can't still remap the STRUCT Object to the Test1Type class.
for (int i=0; i<myObjects.length; i++)
STRUCT myObjects2 = (STRUCT) myObjects;
Object[] Object2 = (Object[])myObjects2.getAttributes();
// Test1Type obj = (Test1Type)myObjects[i];
for (int j=0; j<Object2.length; j++)
System.out.println(Object2[j]);
The line Test1Type obj = (Test1Type)myObjects[i]; is throwing Exception java.lang.ClassCastException: oracle.sql.STRUCT.Do anybody know, if the problem is in the Test1Type class or Test class?
