Hi, Those zero-size files are my fault - sorry! - but I agree with Jeremy that they shouldn't be responsible for the ClassNotFoundException. I guess we better raise a tracker to clear out the empty files, just in the interests of code cleanliness. (Now done - ARIES-312.)
When I made my patch with svn diff, no amount of 'svn delete' would give a patch which when applied produced anything other than an empty file. Is this a natural limitation of the patch format, or did I miss a step creating the patch?

However, this isn't causing the NoClassDefFoundError. I feel you are getting that because the level of the BlueprintExtender class you are using is old. Either * your checkout of the blueprint module isn't at HEAD (unlikely since you said you had checked out the trunk) * the blueprint bundle in you local maven repo are out of date and you need to rebuild the blueprint module * the blueprint bundle in your trunk/samples/blog/blog-assembly/target is out of date compared with the one in your local maven repo and you need to mvn clean install the blog-assembly module. * none of the above :-) but I'm pretty certain the trunk/samples/blog/blog-assembly/target/org.apache.aries.blueprint-0.2-incubating-SNAPSHOT.jar you have doesn't contain the latest BlueprintExtender class.
