I am completely at a loss of what i can do to fix this.
It seems to be working fine in my core project, but i am not doing anything different. It seems like it doesn't recognize the osgi:reference tag, but the namespace definitions should be correct.
Does anyone know what might cause this?
Thnx in advance!

Answer 1

Your xsi:schemaLocation is missing a reference to osgi, it only has osgi-compendium.
You also need to add this:
http://www.springframework.org/schema/osgi
http://www.springframework.org/schema/osgi/spring-osgi.xsd
