RE: [aspectj-users] Applet problems...

[Eyon Land <myjavaland@xxxxxxxxx>]

Thank you for responding!

I do use cflow pointcuts but I can alter security
permissions to grant all.  The error I get is
java.lang.NoClassDefFoundError:
org/aspectj/lang/NoAspectBoundException.

It's acting as though I forgot the aspectjrt.jar as a
dependency.  The strange thing is that all the other
jars are visible to me.  My applet can see the classes
in the other jars, but it can't see the classes in
aspectjrt.jar.  

Specifically  I can put...
	static{
		try{
	
Class.forName("org.apache.axis.message.BodyBuilder");
		}catch(Exception ex){
			throw new RuntimeException(ex);
		}
	
	}
in my applet and see the axis classes (no exception!),
but if I put in a class from aspectjrt.jar I get a
class not found exception.

I'd love to see a working example...

Thank you for your help!
