Hi all!
I'm interested in knowing how I could compose iPOJO components, but only
in terms of components. Let me better explain.
Imagine that I am a service developer (a single service developer). In
this case, from the OSGi point of view, I should implement a Java
interface that describes/represents this service and then publish my
service (suppose that there is only this service inside of a bundle).
But before implementing this interface, I need to well design and
develop my component-based application.
In other words, I need to take advantage of the iPOJO component model
when composing *without taking into account services*, I just want to
plug/unplug components. In some tutorials, I could only see
relationships among iPOJO components through OSGi services.
Let's take an example: suppose that the following illustration is my
application design (a single OSGi service inside of a bundle):
D-->-C-->-B-->-A
where letters are components;
arrows are the connections among them; and
A is the component that finally implements the service interface.
Here is my question: How can I compose D, C and B with no services?
I know it may sound strange the fact of avoiding service interactions.
Actually, I'm interested in both components and services, but I must
also know how much iPOJO component model can help me when developing
"pure" component applications. I've read in another thread about other
OSGi-based component models (Blueprint, DS, Spring-DM, Peaberry),
however I don't know them. Please, feel free to report something even it
is about other OGSi component models rather than iPOJO.
Thank you in advance,
André Lage.
