Re: [equinox-dev] Regarding Lazy Activation

Hello,
 
Super help from both of u. I am now gng through the articles and seeing how it works...

Ajinka,

Do not do this. It is a common newbie mistake: there should be no
start-ordering dependency between bundles.

You do not state *why* you want B to start after A has started. I
assume that you want to publish a service from A and consume it from
B? The correct way to do this is have B *listen* for the availability
of the service it needs to use, then A and B can be started in any
order.

As Petar points out, using Declarative Services (DS) is a much easier
way to implement services, since it takes care of all the aspects of
listening for availability etc. I strongly recommend that you use DS
instead of coding against the low-level OSGi services APIs.

Regards,
Neil
