NoClassDefFoundError when starting bundle extender

[MrVisser]

Hi all,

Through trial and error I've installed a chain of the SpringDM bundles, trying to get the extender to work.

These bundles I've successfully installed:

From lib/:

com.springsource.org.aopalliance-1.0.0.jar
org.springframework.aop-2.5.6.SEC01.jar
org.springframework.beans-2.5.6.SEC01.jar
org.springframework.context-2.5.6.SEC01.jar
org.springframework.core-2.5.6.SEC01.jar

From dist/:

spring-osgi-core-1.2.1.jar
spring-osgi-io-1.2.1.jar

After getting through those, spring-osgi-extender-1.2.1.jar gives me this error when I attempt to start it:

I checked the packages I added and I can't find any duplicates of ListableBeanFactory.

I'm running this in Apache Felix 2.0.4 (actually, Apache Sling 6 which runs in Felix, and includes logging bundles and such).

Any ideas why I'm getting this NoClassDefFoundError while the spring-beans bundle is installed and started?

Thanks,

After restarting the Felix container it seems to load properly now.. strange.

This seems to be resolved, but if anyone has any insight into what happened there I'd appreciate it

Thanks,
