LTW Weaving AspectJ in OSGi is a bit tricky I had done it with a WAS ( OW2 JOnAS based on Felix) and it needs some JVM parameters to work around the MANIFEST configuration. To allow the parent classloader to load the agent Aspectj and/or other classes that are not bundlized, you have to set properties as described here
http://felix.apache.org/site/apache-felix-framework-configuration-properties .html The main properties are org.osgi.framework.bootdelegation org.osgi.framework.bundle.parent These operations are suitable for limited tests or monitoring, for a more strong architecture, you have to bundle your aspects with MANIFEST files as Martin said.

You can weave aspects into OSGi bundles at compile time, but you need to take care of the dependencies that the weaving creates. 1. The woven class will depend on types from org.aspectj.lang or org.aspectj.runtime. So you need to change the OSGi manifest of your host bundle to import those packages. 2. The woven class will depend on the type of the aspect. So depending on where the aspect actually is, you need to add that dependency to the OSGi manifest as well. If you put your aspect into your host bundle, there is nothing you need to do. If your aspect resides in a different bundle, you need to import the package of the aspect into your host bundle via the manifest.
