Hello everyone,

I am just starting with iPOJO and I was wondering what is the 
right/recommended way in iPOJO to select a service late at runtime. 
Imagine a textbox in a GUI that asks for a version and only after the user 
entered version=1.3.5 I can know that the service I want injected is 
v1.3.5. In this case annotations or xml don't work since they are static

What I am currently doing is using an aggregate dependency and then I loop 
myself over all the services (the version is a property of the service 
BTW) and return the one that matches the request

I though of multiple ways of doing this but I don't know if they are 
possible or make sense

1) doing some kind of service registry query where I can explicitly ask 
for the service with the given properties and I will have it returned 
right away
2) modifying the injection filter at runtime; however with this technique 
I would have to wait for the framework to do the injection whenever it 
wants instead of when I need it. i.e. it is asynchronous
3) using the iPOJO API to modify the dependency. Again this solution would 
be async
4) The one I mentioned first. Keep a list of all the services via an 
aggregate dependency and loop through them to find the one that matches
5) other?

Thank you in advance,
