Hi again.
I do understand the meaning of the error i'm getting now:
2008-05-13 19:16:52,781 ERROR [STDERR] [warn] AOP Instrumentor failed to transform
com.mitalteli.bolsaDeTrabajo.vo.VacanteVO

jar:file:/C:/jboss-4.2.1.GA/server/default/tmp/deploy/tmp4165bolsaDeTrabajo-1.0-SNAPSHOT.ear-contents/bolsaDeTrabajo-aop-1.0-SNAPSHOT.aop!/META-INF/jboss-aop.xml7
is trying to apply an already existing methodgetRequisitos for class
com.mitalteli.bolsaDeTrabajo.vo.VacanteVO
| ...
The problem is that I'm not doing it on purpose. I guess I don't know how to
define introductions-mixins and aspects in the jboss-aop.xml file. I don't get it.
I did read the reference guide and the user manual, but I can't find out why it
doesn't work. Maybe I'm skipping the exact paragraph that has the answer, I
don't know.
I guess it is correct to define both a mixin to add attributes and method's that the
class don't have and also an advice to modify the behavior of other already existing
methods. Right?
The original class:
public class VacanteVO
| implements java.io.Serializable
| {
| /**
| * The serial version UID of this class. Needed for serialization.
| */
| private static final long serialVersionUID = -1038158559825459105L;
|
| public VacanteVO()
| {
| this.id = null;
| }
|
| public VacanteVO(java.lang.Long id)
| {
| this.id = id;
| }
|
| /**
| * Copies constructor from other VacanteVO
| *
| * @param otherBean, cannot be <code>null</code>
| * @throws java.lang.NullPointerException if the argument is
<code>null</code>
| */
| public VacanteVO(VacanteVO otherBean)
| {
| this(otherBean.getId());
| }
|
| /**
| * Copies all properties from the argument value object into this value object.
| */
| public void copy(VacanteVO otherBean)
| {
| if (otherBean != null)
| {
| this.setId(otherBean.getId());
| }
| }
|
| private java.lang.Long id;
|
| /**
| *
| */
| public java.lang.Long getId()
| {
| return this.id;
| }
|
| public void setId(java.lang.Long id)
| {
| this.id = id;
| }
|
| }
The mixin interface:
public interface IAspectoVacanteVO {
|
| public java.lang.String getNombre();
| public void setNombre(java.lang.String nombre);
|
| public java.lang.String getRequisitos();
| public void setRequisitos(java.lang.String requisitos);
|
| public java.lang.String getDescripcion();
| public void setDescripcion(java.lang.String descripcion);
|
| public com.mitalteli.bolsaDeTrabajo.domain.VacanteHorario getHorario();
| public void setHorario(com.mitalteli.bolsaDeTrabajo.domain.VacanteHorario
horario);
|
| public com.mitalteli.bolsaDeTrabajo.domain.RangoSueldo getSueldo();
| public void setSueldo(com.mitalteli.bolsaDeTrabajo.domain.RangoSueldo sueldo);
|
| public java.lang.String getContacto();
| public void setContacto(java.lang.String contacto);
|
| public com.mitalteli.bolsaDeTrabajo.domain.VacanteStatus getStatus();
| public void setStatus(com.mitalteli.bolsaDeTrabajo.domain.VacanteStatus status);
|
| public java.lang.Long getEmpresa();
| public void setEmpresa(java.lang.Long empresa);
| }
I won't put here the implementation since it compiles, and I don't think makes any
difference. (Am I right?)
A jboss-aop.xml fragment:
<!-- ****************************************************************************

| </bind>
|
| <!-- FIN: com.mitalteli.bolsaDeTrabajo.vo.VacanteVO -->
VacanteVO is not used anywhere else, but, here (further down in jboss-aop.xml):
<aspect
class="com.mitalteli.bolsaDeTrabajo.useCaseSlices.specific.consultarVacantes.AspectoVacanteDaoBase"
scope="PER_VM"/>
| <bind pointcut="execution(*
com.mitalteli.bolsaDeTrabajo.domain.VacanteDaoBase->toVacanteVO(com.mitalteli.bolsaDeTrabajo.domain.Vacante,
com.mitalteli.bolsaDeTrabajo.vo.VacanteVO))">
| <advice name="methodToVacanteVOAdvice"
aspect="com.mitalteli.bolsaDeTrabajo.useCaseSlices.specific.consultarVacantes.AspectoVacanteDaoBase"/>
| </bind>
| <bind pointcut="execution(*
com.mitalteli.bolsaDeTrabajo.domain.VacanteDaoBase->vacanteVOToEntity(com.mitalteli.bolsaDeTrabajo.vo.VacanteVO,
com.mitalteli.bolsaDeTrabajo.domain.Vacante, boolean))">
| <advice name="methodVacanteVOToEntityAdvice"
aspect="com.mitalteli.bolsaDeTrabajo.useCaseSlices.specific.consultarVacantes.AspectoVacanteDaoBase"/>
| </bind>
But in these cases it's only used as method parameter. That's the way they are
defined in the original coding. It wouldn't be able to catch exactly that method if
the pointcut binding is defined differently, right?
I'm getting the same error for another two classes in which I define a mixin and some
advices. But there is one that it's not being reported as an error. I can't see
any noticeable difference in the coding.
This is the one that is not being reported as an error:

I hope someone knows what is happening.
Thank you all in advance.
