já apaguei o arquivo do banco de dados e criei um novo, o que devo fazer?

OBS: estou usando HSQLDB

hi,

As versões do seu driver jdbc e o banco são compatíveis?

eu apaguei o arquivo gerado pelo hsqldb e ele criou de novo sem problemas, mas continuo sem conseguir acessar as tabelas

Schmidt

você tinha razão, as versões estavam diferentes (a do plugin e a que baixei).
agora estou com o seguinte problema.
criei a seguinte tabela.

CREATE MEMORY TABLE "User"("id" INTEGER NOT NULL PRIMARY KEY,"name" VARCHAR)

e fiz o seguinte arquivo .hbm.xml

package dao ;
/**
 * 
 *
 * @hibernate.class
 *     table="USER"
 *
 */
public class User {
 
  // <editor-fold defaultstate="collapsed" desc=" Property:   String name ">
  private String name;
/**
  *   @hibernate.property
  *     column="name"
  *     type="java.lang.String"
  *   @hibernate.column
  *     name="name"
  */
   public String getName () {
      return name;
   } 
   public void setName (String name) {
      this.name = name;
   }
   // </editor-fold>

  // <editor-fold defaultstate="collapsed" desc=" PrimaryKey:   Long codUser ">
   private Long codUser;
/**
  *   @hibernate.id
  *     generator-class="uuid.hex"
  *     column="codUser"
  *     type="long"
  *   @hibernate.column
  *     name="codUser"
  *     not-null="false"
  */
   public Long getCodUser () {
      return codUser;
   } 
   public void setCodUser (Long codUser) {
      this.codUser = codUser;
   }
   //</editor-fold>
}

também fiz um arquivo facade

package dao;

import org.hibernate.Session;
import org.hibernate.Transaction;

/**
 *  @netbeans.hibernate.facade beanClass=dao.User
 */
public class UserFacade { 
    public void saveUser(User user) {
        Session session = dao.HibernateUtil.currentSession();
        Transaction tx = session.beginTransaction();
        session.save(user);
        tx.commit();
        dao.HibernateUtil.closeSession();
    }    
    
    public void generate() {
        User user = new User();
        user.setCodUser(new Long(0));
        user.setName("alex");
        saveUser(user);
    }
}

mas quando executo o método generate do facade, recebo o seguinte erro
