Hi all.
I hope my question is not too dumb.
I have a project in which I need to specify via AOP all the functionalities of each use
case by it self.
So, I have an almost empty structure with hibernate, spring, and struts (an AndroMDA
structure with jbpm, etc).
In it's various layers I need to add new methods and attributes using introductions.
My problem is that, for example, I add a new "find" method in the Dao object and
when I add a method that uses it in a service object I get an error on compilation,
because this new method can't be found.
I hope I can explain it clearly with code:
For example, the jboss-aop.xml has:
<introduction class="com.mitalteli.bolsaDeTrabajo.domain.VacanteDao">
| <mixin>
| <interfaces>
|
com.mitalteli.bolsaDeTrabajo.useCaseSlices.specific.consultarVacantes.IAspectoVacanteDao
| </interfaces>
|
<class>com.mitalteli.bolsaDeTrabajo.useCaseSlices.specific.consultarVacantes.MixinAspectoVacanteDao</class>
| <construction>new
com.mitalteli.bolsaDeTrabajo.useCaseSlices.specific.consultarVacantes.MixinAspectoVacanteDao(this)</construction>
| </mixin>
| </introduction>
and
<introduction
class="com.mitalteli.bolsaDeTrabajo.service.ServicioConsultarVacantesBase">
| <mixin>
| <interfaces>
|
com.mitalteli.bolsaDeTrabajo.useCaseSlices.specific.consultarVacantes.IAspectoServicioConsultarVacantesBase
| </interfaces>
|
<class>com.mitalteli.bolsaDeTrabajo.useCaseSlices.specific.consultarVacantes.MixinAspectoServicioConsultarVacantesBase</class>
| <construction>new
com.mitalteli.bolsaDeTrabajo.useCaseSlices.specific.consultarVacantes.MixinAspectoServicioConsultarVacantesBase(this)</construction>
| </mixin>
| </introduction>
and their respective mixins contain:
/**
| * @see
com.mitalteli.bolsaDeTrabajo.domain.VacanteDao#encuentraConCriterios(com.mitalteli.bolsaDeTrabajo.vo.CriteriosBusquedaConsultarVacantesVO)
| */
| public java.util.List encuentraConCriterios(final
com.mitalteli.bolsaDeTrabajo.vo.CriteriosBusquedaConsultarVacantesVO criteria)
| {
| if (criteria == null)
| {
| throw new IllegalArgumentException(
|
"com.mitalteli.bolsaDeTrabajo.domain.VacanteDao.encuentraConCriterios(com.mitalteli.bolsaDeTrabajo.vo.CriteriosBusquedaConsultarVacantesVO
criteria) - 'criteria' can not be null");
| }
| try
| {
| return this.handleEncuentraConCriterios(criteria);
| }
| catch (Throwable th)
| {
| throw new java.lang.RuntimeException(
| "Error performing
'com.mitalteli.bolsaDeTrabajo.domain.VacanteDao.encuentraConCriterios(com.mitalteli.bolsaDeTrabajo.vo.CriteriosBusquedaConsultarVacantesVO
criteria)' --> " + th,
| th);
| }
| }
and
/**
| * @see
com.mitalteli.bolsaDeTrabajo.service.ServicioConsultarVacantes#encuentraVacantes(com.mitalteli.bolsaDeTrabajo.vo.CriteriosBusquedaConsultarVacantesVO)
| */
| public /*protected*/ com.mitalteli.bolsaDeTrabajo.vo.ResumenVacanteVO[]
handleEncuentraVacantes(com.mitalteli.bolsaDeTrabajo.vo.CriteriosBusquedaConsultarVacantesVO
criteria)
| throws java.lang.Exception
| {
| //List vacantes =
servicioConsultarVacantesBase.getVacanteDao().encuentraConCriterios(criteria);
| List vacantes = getVacanteDao().encuentraConCriterios(criteria);
| getVacanteDao().toResumenVacanteVOCollection(vacantes);
| return (ResumenVacanteVO[])vacantes.toArray(new ResumenVacanteVO[0]);
| }
So, as I told before, the Dao class should have now a find method called:
encuentraConCriterios, so the call to getVacanteDao().encuentraConCriterios(criteria);
should be found, but that's not the case. I get the error message:
...\useCaseSlices\specific\consultarVacantes\MixinAspectoServicioConsultarVacantesB
| ase.java:[162,39] cannot find symbol
| symbol : method encuentraConCriterios(com.mitalteli.bolsaDeTrabajo.vo.Criterios
| BusquedaConsultarVacantesVO)
| location: interface com.mitalteli.bolsaDeTrabajo.domain.VacanteDao
I'm trying to do loadtime waving on a jboss-4.2.1.GA with jboss-aop-1.5.6 with jdk 6
update 3, and jre 6 update 5 on my WinXP pro Service pack2 computer.
So I'm not waving the classes yet, just compiling them. I guess I'm doing some
thing wrong.
Is this even possible? Maybe If I compile and wave the first mixin, and then compile and
wave the second one, instead of doing loadtime waving?
Any Ideas?
I'm very very new to all this AOP technology, so maybe I don't understand
something right.
Thank you all in advance.
Ely.
