That’s an interesting idea. I didn’t realize that OSGi had built-in weaving capabilities. I looked at the spec and saw that there’s a partial example of how to use WeavingHook, but it didn’t talk about how to actually perform the bytecode manipulation, leaving it instead as an “exercise to the reader”. Where can I find an example of how to do this? Or would it be easier if I simply used a tool like AspectJ? Does AspectJ play nicely with OSGi?

If you want to get really crazy you can go to full Weaving (Chapter 56 of Core spec). - Ray On Thu, Feb 18, 2016 at 11:17 AM, elias vasylenko <eliasvasyle...@gmail.com<mailto:eliasvasyle...@gmail.com>> wrote: The standard OSGi way I suppose would be to use service hooks to intercept service registrations, and re-register proxied versions.

For example, if I have a service defined with a method that takes a “name” string and queries a database to return an “address” string, I want to be able to build a separate component that will listen for these method calls and invoke a callback both when the method is called, where I can see the name string that was passed, and a callback when the method returns, where I can see the address string that comes back. I could do this manually using something like aspect-oriented programming, but if there is a way to do this that is built into OSGi, then it will save me the trouble.
