You have to set the criteria as parameters to get result in ItemsDAOImpl

public List searchitems(String category_id, String publsiher_id) {

        return sessionFactory.getCurrentSession().createQuery("from Items E where E.category_id = :category_id AND E.publisher_id= :publisher_id")
                .setParameter("category_id", category_id)
                .setParameter("publisher_id", publsiher_id)
                .list();

    }

In your searchResult.jsp you are iterating over listItems2 but you added is attribute as items in your controller.

Change

On an other note, please name the entities properly. Entity name should be Item and collection name should Items. But do that later, first try to fix the current problem.
