OSGI LogService.log method does not work!

Question

I have the weirdest bug, when writting my LogHelper class.

I am using org.osgi.service.log.LogService (with Apache Felix implementation).

Now I can call the:

LogService.log(int level, String message)

with no problems, but when I try to use the one with the exception:

LogService.log(int level, String message, Throwable exception)

Eclipse highlights the call as wrong, and gives me this wierd error message:

The type org.osgi.framework.ServiceReference cannot be resolved. It is indirectly referenced from required .class files

Answer 1

According to nice folks at apache felix this is because Eclipse does not see ServiceReference in my classpath.

Putting the "org.osgi.core" into my (maven+osgi) dependencies, fixed it.

Answer 2

Your bundle should import package org.osgi.framework that is used by LogService.
