Quando mando compilar o meu projeto (build), recebo a seguinte mensagem

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 :frowning:

[quote=schmidt]hi,

Schmidt[/quote]

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

[code]
package dao ;
/**
*
*

  • @hibernate.class
  • table="USER"

*/
public class User {

//
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;
}
//

//
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;
}
//
}[/code]

também fiz um arquivo facade

[code]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);
    }
    }[/code]

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

você tem alguma idéia? :wink:
