QuerySyntaxException class is not mapped
----------------------------------------
Key: EJBTHREE-1441
URL: https://jira.jboss.org/jira/browse/EJBTHREE-1441
Project: EJB 3.0
Issue Type: Task
Environment: JBoss 4.2.0.GA - Seam 2.0.1.GA
Reporter: Kenneth René Sánchez Sánchez
I have a jar file (acad.jar) than contain TemaIcfes Entity:
package co.academico.entidades;
import java.io.Serializable;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;
import javax.persistence.GeneratedValue;
import org.jboss.seam.annotations.Name;
@Entity
@Name("TemaIcfes")
@Table(name = "temas_icfes")
public class TemaIcfes implements Serializable{
@Id
@GeneratedValue
private short tema;
private String descripcion_tema;
public short getTema(){
return tema;
}
public void setTema(short tema){
this.tema = tema;
}
public String getDescripcion_tema(){
return descripcion_tema;
}
public void setDescripcion_tema(String descripcion_tema){
this.descripcion_tema = descripcion_tema;
}
}
The problem is that when I use it in another application through an EJB shows the
following error:
Exception during request processing: Caused by javax.el.ELException with message:
"javax.ejb.EJBTransactionRolledbackException:
org.hibernate.hql.ast.QuerySyntaxException: TemaIcfes is not mapped [SELECT a FROM
TemaIcfes a ORDER BY tema]"
