Welcome to part 6 of the lecture on OSGI, OSGI Component Configuration.
After listing to this part, you should be able to
Declare component lifecycle methods.
Make your component configurable.
We will not review the older list five ways of configuring components. If
that is what is used in your project you should better read documentation.
In OSGI, to make a component configurable, the
developer defines a certain data structure called MetaType.
That MetaType has two important parts
Object class Definition
Object Class Definition defines Attributes, that determines the configurable properties of a component and
Designate binds the Object Class Definition to the component.
In a bundle this data structure exists as an XML document that is a separate
XML document plus entries in the main component configuration XML.
In the Java code this structure is defined using several annotations.
