You might be interested in looking at the support we put in Equinox for load
time weaving of aspects. See
http://www.eclipse.org/equinox/incubator/aspects/index.php
This approach addresses issues around the actual weaving, the discovery of
aspects and the addition of dependencies required to load the woven code.
Further issues/questions about this stuff should be directed towards the
equinox mailing list ([EMAIL PROTECTED])

> Hi all,

> it right now. If I got it right, OSGi uses classloaders to implement
> the
> modularity and to expose classes that are exposed as services. Now, I'm
> working on a framework that applies AOP-like techniques at class
> loading
> time, and since it is a framework, I'm thinking of making it OSGi
> compliant.
> My doubt is about my use of classloaders: should I worry about my

> classloaders? Please note that the classes that implement services do
> not
> change their definition, but change the definition of application-side
> classes. Also the classloader that provides such manipulation is a
> class that
> does not change at runtime, so my service classes and objects are
> "stable",
