私はネットビーンズを使用しています。エンティティ クラスを作成しました。現在、テーブルの作成方法がわかりません。そこで、persistence.xml ファイルで「drop-and-create-tables」を使用しました。サーブレットを使用してデータベースにデータを入力すると、そのエラーで失敗します。そのエラーについてGoogleには何もありません。

ここに私の永続化ファイルがあります...

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.0" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">
  <persistence-unit name="com.uc.ermis_BookUCReadyTalk_war_1.0-SNAPSHOTPU" transaction-type="JTA">
    <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
    <jta-data-source>jdbc/sample</jta-data-source>
    <exclude-unlisted-classes>false</exclude-unlisted-classes>
    <properties>
      <property name="eclipselink.ddl-generation" value="drop-and-create-tables"/>
    </properties>
  </persistence-unit>
</persistence>

編集 - データを永続化するコードの追加 - netbeans を使用してエンティティ クラスからこれらのクラスを生成しました。- テーブルがデータベースに存在しません。persistence.xml を value="create-tables" に変更しました

@Stateless
public class EventFacade extends AbstractFacade<Event> {
    @PersistenceContext(unitName = "com.uc.ermis_BookUCReadyTalk_war_1.0-SNAPSHOTPU")
    private EntityManager em;

    @Override
    protected EntityManager getEntityManager() {
        return em;
    }

    public EventFacade() {
        super(Event.class);
    }

}

public abstract class AbstractFacade<T> {
    private Class<T> entityClass;

    public AbstractFacade(Class<T> entityClass) {
        this.entityClass = entityClass;
    }

    protected abstract EntityManager getEntityManager();

    public void create(T entity) {
        getEntityManager().persist(entity);
    }

    public void edit(T entity) {
        getEntityManager().merge(entity);
    }

    public void remove(T entity) {
        getEntityManager().remove(getEntityManager().merge(entity));
    }

    public T find(Object id) {
        return getEntityManager().find(entityClass, id);
    }

    public List<T> findAll() {
        javax.persistence.criteria.CriteriaQuery cq = getEntityManager().getCriteriaBuilder().createQuery();
        cq.select(cq.from(entityClass));
        return getEntityManager().createQuery(cq).getResultList();
    }

    public List<T> findRange(int[] range) {
        javax.persistence.criteria.CriteriaQuery cq = getEntityManager().getCriteriaBuilder().createQuery();
        cq.select(cq.from(entityClass));
        javax.persistence.Query q = getEntityManager().createQuery(cq);
        q.setMaxResults(range[1] - range[0]);
        q.setFirstResult(range[0]);
        return q.getResultList();
    }

    public int count() {
        javax.persistence.criteria.CriteriaQuery cq = getEntityManager().getCriteriaBuilder().createQuery();
        javax.persistence.criteria.Root<T> rt = cq.from(entityClass);
        cq.select(getEntityManager().getCriteriaBuilder().count(rt));
        javax.persistence.Query q = getEntityManager().createQuery(cq);
        return ((Long) q.getSingleResult()).intValue();
    }

}

モデル

@Entity
@XmlRootElement
public class Event implements Serializable {

    private static final long serialVersionUID = 1L;
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private String id;
    private String title;
    private String description;
    private boolean allDay;
    @Temporal(TemporalType.TIMESTAMP)
    private Date start;
    @Temporal(TemporalType.TIMESTAMP)
    private Date end;
    private String url;
    private String className;
    private boolean editable;
    private boolean startEditable;
    private boolean durationEditable;
    private String color;
    private String backgroundColor;
    private String borderColor;
    private String textColor;
}

データベースにデータを入力しようとしているサーブレット

@EJB
    EventFacade eventFacade;

private void recreateDb() {
        Event ev = new Event();
        ev.setTitle("Sample item");
        ev.setDescription("Sample description");
        ev.setAllDay(true);
        eventFacade.create(ev);
    }

データベースの予約語 ( END) を使用している可能性があります。@Columnアノテーションを使用してみてください。

@Temporal(TemporalType.TIMESTAMP)
@Column(name = "START_DATE")
private Date start;
@Temporal(TemporalType.TIMESTAMP)
@Column(name = "END_DATE")
private Date end;
