call PL/SQL procedure in hibernate

/*GetStocks(stockcode VARCHAR2(20)) is procedure name created by PL/SQL*/
 
//1.Native SQL – createSQLQuery
//You can use createSQLQuery() to call a store procedure directly.
 
Query query = session.createSQLQuery(
	"CALL GetStocks(:stockCode)")
	.addEntity(Stock.class)
	.setParameter("stockCode", "7277");
 
List result = query.list();

	Stock stock = (Stock)result.get(i);
	System.out.println(stock.getStockCode());
}
 
 
//2. sql-query in XML mapping file
//Declare your store procedure inside the “sql-query” tag.
 
//<!-- Stock.hbm.xml -->
