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]" Classes: HacerMantenimiento.java: package co.academico.admin;
