Gettin Invalid column index error

[Sheeli Louis]

Hi,

i have a oracle stored proc at remote location and writing JDBC code to call the SP.That sP has both IN and OUT paramsas given below

CREATE OR REPLACE TYPE UDI_LIST AS TABLE OF VARCHAR2(14)


CREATE OR REPLACE TYPE UDI_GL AS OBJECT( UDI varchar2(14),GL_RF_NO number )
CREATE OR REPLACE TYPE UDI_GL_LIST AS TABLE OF UDI_GL


this is the java code.....

Session session =getSessionFactory().openSession();
        session.beginTransaction();
        
        session.doWork(new Work(){

			@Override
			public void execute(Connection con) throws SQLException {
				
				C3P0NativeJdbcExtractor cp30NativeJdbcExtractor = new C3P0NativeJdbcExtractor(); 
		        OracleConnection connection = (OracleConnection) cp30NativeJdbcExtractor.getNativeConnection(con);
		        System.out.println("Got Oracle Connection");
				
		        ArrayDescriptor descriptor = ArrayDescriptor.createDescriptor("UDI_LIST", connection);
				ARRAY in_param = new ARRAY(descriptor,connection,udis.toArray());
				//ArrayDescriptor desc = ArrayDescriptor.createDescriptor("UDI_GL_LIST",connection);
				
				Map map = con.getTypeMap();
				map.put("UDI_GL", PostRefSqlType.class);
				
				OracleCallableStatement cs = (OracleCallableStatement) connection.prepareCall("{call UDI_GLREF(?,?)}");
								
				cs.setArray(1, in_param);
				cs.registerOutParameter(2, OracleTypes.ARRAY, "UDI_GL_LIST");
				
				
				cs.execute();
				ARRAY out_param = (ARRAY)cs.getArray(1);
				
				Object[] objects = (Object[]) out_param.getArray();
				
				for(int i =0 ; i < objects.length; i++){
					PostRefSqlType obj = ((PostRefSqlType)objects[i]);
					ETFPostRef refObj = new ETFPostRef();
					refObj.setUniqueDealId(obj.getUniqueDealId());
					refObj.setPosRef((String)obj.getPosRef());
					refObj.setTimeStamp(new Date());
					refList.add(refObj);
				}
				connection.commit();
				connection.close();					
			}
       	
        });
