[aspectwerkz-user] Problem with Plug-in org.codehaus.aspectwerkz.ide.eclipse.core

Hi all,

I m new in using Aspectwerkz.
I have downloaded the eclipse plugin IDE from
http://docs.codehaus.org/display/AW/Eclipse+plugin

and I m trying to run the HelloWorld example from
http://docs.codehaus.org/display/AW/Tutorials

I have compiled the program and this message in the log of eclipse:
!ENTRY AspectWerkz 1 0 2006-05-01 10:34:50.678
!MESSAGE annotate MyAspect.class

!ENTRY AspectWerkz 1 0 2006-05-01 10:34:50.688
!MESSAGE annotate HelloWorld.class

!ENTRY AspectWerkz 1 0 2006-05-01 10:34:50.718
!MESSAGE weaving MyAspect.class

!ENTRY AspectWerkz 1 0 2006-05-01 10:34:50.728
!MESSAGE notified for testAOP.MyAspect, 0 jp(s)

!ENTRY AspectWerkz 1 0 2006-05-01 10:34:50.728
!MESSAGE weaving HelloWorld.class

!ENTRY AspectWerkz 1 0 2006-05-01 10:34:50.748
!MESSAGE notified for testAOP.HelloWorld, 1 jp(s)

From the message above, I can see that the weaving was successfull.

I get a problem when trying to run the Main method of my code.
I get this error:
Plug-in org.codehaus.aspectwerkz.ide.eclipse.core was unable to load class
org.codehaus.aspectwerkz.ide.eclipse.core.launch.LaunchConfigurationDelegate
.


Can anyone please help to fix this problem ?

Thx in advance for your quick replies.

Best regards,

Karimou
