Can or should a blueprint xml file be inside a Karaf KAR file?

Question

In a Karaf .kar file, should the blueprint xml file be inside the jar contained in the kar file OR should it be within the kar file itself.

Also, can a blueprint xml be inside a Karaf .kar file or must it be within the contained jar contained within the .kar?

Answer 1

Karaf allows to deploy plain blueprint.xml files but this is not covered by any standard. The blueprint spec conformant way to deploy a blueprint.xml is to put it into a bundle in the path OSGI-INF/blueprint.

You put the blueprint file into the jar and the jar into the kar.
