Do I need an external jar for osgi?
回答1:
A class not found exception on a core osgi class, seems that you are missing a jar/framework jar that implements OSGi specification. Check which OSGi implementation your target system supports. If you have choice in choosing you can try,
- Apache felix OSGi
- Eclipse equinox OSGi

If you are trying to run example from IntelliJ it may be problem that you haven`t imported maven dependencies. When you import java project into IntelliJ you must also import its dependencies (they are not imported by default).
