OSGi LogService error when deploying apache sling in an app container

Question

I am new to sling (and jackrabbit). I can start the standalone sling instance without any problem. When I try to deploy the webapp in an app container, I get the following exception in the server.log:

ERROR: Error starting slinginstall:org.apache.felix.http.bridge-2.2.0.jar (java.lang.NoClassDefFoundError: org/osgi/service/log/LogService)

I am using Java 6. I get the same error regardless of whether I use JBoss or Glassfish. I've also tried building the source from the latest subversion checkout and building from the latest official release of the source code. It seems like it is expecting some sort of logging service (or listener) to be active, but I don't know how to set one up.

Thanks for any help you all can offer!

Answer 1

This was resolved by an update to the code (revision r1609438) and the problem no longer occurs during deployment of the latest code. Many thanks to the Apache Sling team for their fast response time!
