以下是netbeans根據實體自動生成的CURD模板：

/** To change this template, choose Tools | Templates* and open the template in the editor.*/package com.medea.order.session;import com.medea.order.entity.Storeorder;import java.util.List;
import javax.ejb.Stateless;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;/**** @author Administrator*/
@Stateless
public class StoreorderFacade implements StoreorderFacadeRemote {@PersistenceContextprivate EntityManager em;public void create(Storeorder storeorder) {em.persist(storeorder);}public void edit(Storeorder storeorder) {em.merge(storeorder);}public void remove(Storeorder storeorder) {em.remove(em.merge(storeorder));}public Storeorder find(Object id) {return em.find(Storeorder.class, id);}public List<Storeorder> findAll() {List<Storeorder> so=em.createQuery("select object(o) from Storeorder as o").getResultList();//  XmlUtil.writeXML(so, "aa");return so;}}

可以參考一下參數和返回值，然后自己根據情況修改。
