Kiev,

 

OSGi will not allow you any non-OSGi class loading tricks.

 

Yes, you can have a fragment for the system bundle. These are called framework extension bundles.

In order to be found by Equinox this fragment has to be co-located with the system bundle and you have to register it by the system property

osgi.framework.extensions=<FRAGMENT>

Thanks for the response.

I have tried to run in two different ways:

1 - If I put aspectJrt.jar in the classpath I get an explicit dependency error on the AJ classes
2 - Then, I've set the aspectJ\lib in the java.ext.dirs option and I've got the error that I sent.

I'll check on that other tip that you gave me.
Can I use fragment bundles with the bundle 0 (framework bundle) ?

Thanks again

Kiev,

 

Thank you for the information provided.

 

As far as I understand you are weaving some aspects into Equinox (into the FrameworkLogEntry), right?

 

This will create dependencies from Equinox to your classes and possibly to AspectJ (for example when using around advices). These dependencies cannot be resolved, because in OSGi only dependencies declared in the bundle manifest are visible.

 

Maybe you could put your classes and the AspectJ runtime library into a framework extension fragment (look for details in the Eclipse Wiki).

Any comments on this?

 

Another solution could be to use Equinox Aspects and load-time weaving.

Actually I'm not using the Equinox from the Equinox Aspects project.
I'm doing AspectJ compile-time (offline) weaving of a standard Equinox framework.

AspectJ 1.5
Equinox 3.2.0

Does the list allow the attaching of a file?
I can attach the weaved jar.

Thanks for the help.

Kiev,

 

Could you please provide some more information about your setting?

 

- Are you using compile-time weaving or loag-time weaving by Equinox Aspects?

- Which AspectJ version are you using?

 

Further it could be valuable if you could attach your project(s) …

 

Heiko

Hello,

I weaved Equinox framework v 3.2.0 with AspectJ and I am getting the following the weaved framework:

Exception in thread "main" java.lang.NoClassDefFoundError: org/eclipse/osgi/framework/log/FrameworkLogEntry
Caused by: java.lang.ClassNotFoundException: org.eclipse.osgi.framework.log.FrameworkLogEntry
        at java.net.URLClassLoader$1.run(Unknown Source)
        at java.security.AccessController.doPrivileged(Native Method)
        at java.net.URLClassLoader.findClass(Unknown Source)
        at java.lang.ClassLoader.loadClass(Unknown Source)
        at java.lang.ClassLoader.loadClass(Unknown Source)
        at java.lang.ClassLoader.loadClassInternal(Unknown Source)


The FrameworkLogEntry class is the weaved jar. Does anybody know in detail how the class loading works or why that is happening?

This version does not use digitally signed jars. I found errors regarding the hashing of classes with version 3.3 and that is why I've tried weaving a previous version.

Thanks,

Kiev Gama
