I'm constantly getting the following exception:

<osgi:service ref="referenceDataManager"

	</aop:config>

Before using pointcuts in the blueprint configuration I tried the @Transactional annotation and it was working fine. Now using pointcuts I have this classloading trouble. I'm wondering if it is possible to use pointcuts in the blueprint configuration file?

Presumably the bundle that contains org.aspectj.weaver.tools.PointcutParser does not import the package com.qualitype.genetics.ref.io. This is one of the issues of attempting load time weaving in an OSGi environment. I guess you could try adding the appropriate import (see this Virgo FAQ if you want to avoid hacking 3rd party bundle manifests). There is also some historic information on this subject here, but my feeling is that you are trail-blazing... Wink

Adding the package to the aspectj.weaver bundle did not help. Instead I had to add my com.qualitype.genetics.ref.io package to org.springframework.orm, org.springframework.transaction and org.eclipse.gemini.blueprint.core. All these bundles try to load the class during startup. Sad

Well, my intention was to avoid any hard-coded spring dependencies, but for now I switched back to using the @Transactional annotation.

Btw. The OSGi Early Draft 2012.10 describes how to use transactions in osgi. Is using @Transactional "supported" or should I use bean-managed transactions?
