hi, from what i can see in the errorlog it can find the class org.andromda.samples.aop.sades.domain.SolicitudProfesorGrupoDaoImpl. can you think of any reason why it says that it doesnt find the class? i cant see any jboss aop related messages in your log; do you precompile the introduction, or is it done at loadtime? hm, if you deployed the injboss example in the same appserver and it worked its possibly only a packaging issue thats causing it, but im not sure. - im rambling a bit here, but if youre still stuck try to provide some more info and ill look into it.
