Dear all,

I have a problem with load-time weaving and equinox aspects.

My setup is the following: I have a supplemented bundle 'B' and a bundle 'A' containing an aspect. According to http://java.dzone.com/articles/aspect-oriented-programming I created bundle A as OSGi bundle on the Equinox framework and converted it to an AspectJ project. According to http://wiki.eclipse.org/Equinox_Weaving_QuickStart I have :

1) AJDT (2.2.1.e42x-RELEASE-20120921-1400) and Equinox Weaving (Equinox Weaving SDK 1.0.200.I20120427-0800) installed in my Eclipse Juno (20120620-1657)
2) defined the aspect in a package
3) configured my Manifest.MF to:

Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: A
Bundle-SymbolicName: a.a
Bundle-Version: 1.0.0.qualifier
Bundle-RequiredExecutionEnvironment: JavaSE-1.6
Require-Bundle: org.aspectj.runtime,
 b.b;bundle-version="1.0.0",
Export-Package: a.a;aspects="AspectA"
Eclipse-SupplementBundle: b.b;bundle-version="1.0.0"


4) in the plug-ins tab off my run configuration (for an Eclipse application) I made sure that the following plugins are selected:
org.aspectj.weaver (Start Level: default Auto-Start: default)
org.eclipse.equinox.weaving.aspectj (Start Level: 2 Auto-Start: true)
org.eclipse.equinox.weaving.caching (Start Level: default Auto-Start: default)
org.eclipse.equinox.weaving.hook (Start Level: default Auto-Start: false)


5) I added the following VM arguments:
-Dosgi.framework.extensions=org.eclipse.equinox.weaving.hook
-Dorg.aspectj.osgi.verbose=true
-Dorg.aspectj.weaver.showWeaveInfo=true

My problem is that LTW cannot be performed. The bundles org.eclipse.equinox.weaving.hook cannot be found and the bundle org.eclipse.equinox.weaving.caching cannot be started, what results in ClassNotFoundException and NoClassDefFoundError exceptions, see the trace below.

What do I have to do or what did I configured wrongly?

I have the impression that the erroneous behavior is caused by step four. First, I am not sure if I should run my code as an Eclipse application or if I should choose an OSGi framework application? Second, I cannot modify the Auto-Start for the org.eclipse.equinox.weaving.hook from false to true or to default. I observe that unlike the other plugins the *.hook plugin has a violet not a blue plugin icon. I do not know what this means but perhaps it is important. Is there anyone using AJDT and LTW in Eclipse Juno who could help me out?


Best regards,
Helge
