Problem calling oracle SP from Java

Question

Hi I am trying to call an oracle SP from Java program and getting the error code 17060. Below is my code:
Oracle SP:
create or replace type item as object (itemnumber varchar2(9),itemdesc varchar2(35));
create or replace type uom as object (prodUOM varchar2(18), ratioDen NUMBER(1));
CREATE OR REPLACE TYPE uom_Arr aS VARRAY(100) OF uom;
create or replace package test_pkg_xml is
procedure test_sp_xml (item_rec item,
uom_tbl uom_arr);
end test_pkg_xml;
create or replace package body test_pkg_xml is
procedure test_sp_xml (item_rec item,
uom_tbl uom_arr)
is
begin
null;
end;
end test_pkg_xml;
Java Code
public class item implements SQLData {
private String sql_type;
public String itemnumber ;
public String itemdesc ;
public String getSQLTypeName() throws SQLException { return sql_type; }
public void readSQL(SQLInput stream, String typeName)throws SQLException
sql_type = typeName;
itemnumber = stream.readString();
itemdesc = stream.readString();
public void writeSQL(SQLOutput stream) throws SQLException
System.out.println("in write sql");
stream.writeString (itemnumber);
stream.writeString (itemdesc);

String itmname = DOMUtil.getSimpleElementText( itemMaster, "itemNumber" );

obj3.prodUOM = itmprodUOM;
String itmratioDen = DOMUtil.getSimpleElementText(
(Element)uom.item(i), "ratioDen" );
obj3[i].ratioDen = itmratioDen;
System.out.println( " "+ itmprodUOM +" ("+itmratioDen+")" );
try
Hashtable map = new Hashtable();
map.put ("item", Class.forName ("com.tgt.dstb.dwm.dstbtowm.dao.item"));
conn.setTypeMap(map);
System.out.println("here 11111 ");
CallableStatement stmt = conn.prepareCall("call test_pkg_xml.test_sp_xml(?,?)");
System.out.println("here 2 ");
stmt.setObject(1,obj1);
System.out.println("here 3 ");
stmt.setObject(2,obj3);
System.out.println("here 4 ");
stmt.execute();
System.out.println("here 5 ");
}catch (SQLException e)
System.out.println("exception :"+e.getErrorCode());
Can you please point out where I might be going wrong with the code? Any help would be greatly appreciated.
PS : I am getting the error 17060 after the stmt : System.out.println("here 2 ");
Thanks,

Avi, I changed my code to:
package com.tgt.dstb.dwm.dstbtowm.dao;
import javax.xml.parsers.*;
import org.w3c.dom.*;
import java.sql.Connection;
//import java.sql.CallableStatement;
import java.sql.*;
//import java.util.Map;
//import java.util.Hashtable;
import oracle.sql.ArrayDescriptor;
import oracle.sql.*;
import oracle.jdbc.*;
public class TestDOM
public static void test(Connection conn) throws Exception
     item obj1 = new item();
     Obj2 obj2 = new Obj2();
     Obj2[] obj3 = {new Obj2(), new Obj2()};
     String sql = " call test_pkg_xml.test_sp_xml(?,?)";
     DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder parser = factory.newDocumentBuilder();
Document document = parser.parse( "item.xml" );
Element itemMaster = document.getDocumentElement();
NodeList itemNumber = itemMaster.getElementsByTagName("itemNumber");
NodeList itemDesc = itemMaster.getElementsByTagName("itemDesc");
System.out.println("Item = ");
String itmname = DOMUtil.getSimpleElementText( itemMaster, "itemNumber" );
String itmdesc = DOMUtil.getSimpleElementText( itemMaster, "itemDesc" );
obj1.itemnumber = itmname;
obj1.itemdesc = itmdesc;
System.out.println("itmname = " + obj1.itemnumber );
System.out.println("itmdesc = " + obj1.itemdesc );
NodeList uoms = itemMaster.getElementsByTagName("uoms");
NodeList uom = itemMaster.getElementsByTagName("uom");
System.out.println("uom = ");
for( int i=0; i<uom.getLength(); i++ ) {
String itmprodUOM = DOMUtil.getSimpleElementText(
(Element)uom.item(i),"prodUOM" );
obj3.prodUOM = itmprodUOM;
String itmratioDen = DOMUtil.getSimpleElementText(
(Element)uom.item(i), "ratioDen" );
obj3[i].ratioDen = Integer.parseInt(itmratioDen);
System.out.println( " "+ itmprodUOM +" ("+itmratioDen+")" );
try
System.out.println("here 1 ");
OracleCallableStatement stmt = (OracleCallableStatement)
conn.prepareCall("BEGIN test_pkg_xml.test_sp_xml(?,?); END;");
System.out.println("here 1.1 ");
System.out.println("here 1.2 ");
ArrayDescriptor desc1 = ArrayDescriptor.createDescriptor("UOM_ARR", conn);
     ARRAY array_to_pass1 = new ARRAY(desc1, conn, obj3);
System.out.println("here 2 ");
stmt.setObject(1,obj1,OracleTypes.STRUCT);
System.out.println("here 3 ");
stmt.setArray(2,array_to_pass1);
System.out.println("here 4 ");
stmt.execute();
System.out.println("here 5 ");
     }catch (Exception e)
          e.printStackTrace();
However, now I the code is printing
"here 1 "
and then giving
"[1/4/07 11:37:28:133 CST] 00000036 SystemErr R java.lang.ClassCastException: com.ibm.ws.rsadapter.jdbc.WSJdbcCallableStatement"
at "OracleCallableStatement stmt = (OracleCallableStatement)
conn.prepareCall("BEGIN test_pkg_xml.test_sp_xml(?,?); END;");"
statement.
I am using Rational App Developer Version 6.0.1 and getting a connection using
the below code:
          DataSource     dataSource=null ;
          Context jndiContext = new InitialContext();
          dataSource =
(DataSource)jndiContext.lookup("java:comp/env/jdbc/DWM3DDS");
          Connection wsConn = dataSource.getConnection();
Looks like this exception occurs when I am casting java.sql.Connection object to OracleCallableStatement. Do you have any idea why this might be occuring? Have you encountered this kind of a problem?
Thanks,
Nitin
