Hi.
(Sorry for such a long message)
I've been trying for the past few weeks now to add some aspects to my application with no success.
What I want to do, as my first step, to add some interceptors to add functionality to already existing classes.
My questions are:
a) I managed to run the inJbos example (great one, by the way), and it wasn't clear if it's possible to aop the classes of an ear file with a .aop file in it, or if it must wave the classes at runtime. What I mean is: Can I run apoc with the intercepted classes before I pack my .aop file?
b) If I modify some entity classes, how should hibernate configuration files get modified? For instance, if I add a new attribute that should be referred by a database field? (I'm not sure about how to add completely new functionalities to classes)
c) I managed to create a maven2 structure in order to have my bpm2struts, spring, hibernate, etc added with an “aop†project. I hope someone can help me
What should happen with the example, is that some messages should get printed on the adviced constructor. I could send the sources if needed.
When I deploy the project, nothing get's transformed. I'm sure the jboss-aop.xml is being parsed by JBoss.4.2.1.GA server because I didn't put all the “ org.andromda.samples.aop.sades.domain.SolicitudProfesorGrupoDaoImpl†name but only the class name (SolicitudProfesorGrupoDaoImpl) and it complained.
Two days ago I discovered an error message on compile, and I can't figure out how to fix it:

The jboss-aop.xml file:

My app pom.xml (is the one that builds the final ear)
...
| <dependencies>
| ..

| <artifactId>sades-aop</artifactId>
| <bundleFileName>${application.id}-aop-${pom.version}.aop</bundleFileName>
| <includeInApplicationXml>true</includeInApplicationXml>
| </javaModule>
| ...
This way I obtain an ear file with the correct structure (as far as I can tell):
anonymous wrote : sades-1.0-SNAPSHOT.ear
| META-INF
| application.xml
| ...
| sades-aop-1.0-SNAPSHOT.aop
| META-INF
| jboss-aop.xml
| ...
And also my regular jar files, and the war file.
Thank you all in advance.
