Answer 1

Join restrictions are supported by Hibernate but the syntax is not the same than SQL. You have to replace the ON keyword by WITH in Hibernate !

Answer 2

productList = (List<Object[]>) session.createQuery("SELECT op.username, op.email, orders.p_id, orders.o_id, product.listed_price " + "FROM Orders  orders " +"INNER JOIN orders.OrderProcessing as op " +  "ON op.u_id = orders.u_id"+ "INNER JOIN orders.Product as product " + "ON product.p_id = orders.p_id "+ "WHERE product.p_id = '"+p_id +"'" "ORDER BY op.username").list();

You have to check the Orders table. orders.orderProcessing is not a table its a column from orders table.

Answer 3

Chetter Hummin is right, "on" isn't supported in HQL. See this: http://docs.jboss.org/hibernate/orm/3.3/reference/en/html/queryhql.html
