http://localhost:8081/Spring_hibernate/search?keyword=core

this is dao part

public Offer getSearchByName(String companyName) {
        Session session = sessionFactory.openSession();
        Query<Offer> query = session.createNamedQuery("findBy.app", Offer.class);
        query.setParameter("offerDetails", companyName);

        <td><a href="/Spring_hibernate/updateOffer?offerId=${temp.id}">Update</a></td>
       </tr>
   </c:forEach>

CodePudding user response：

You can only iterate valid Object array such as Collection, Map, Iterator, Enumeration or String. Anything else can't be iterated by <c:forEach>.

CodePudding user response：

You want to show a list. Get your query result in a collection, set that collection in "searchObject".

If the query result is not a collection, then remove forEach iterator and simply access the fields (searchObject.price).
