Re: [aspectj-users] AspectJ classes in Cortona VRML Browser

[Andrew Clement <CLEMAS@xxxxxxxxxx>]

Hi,

Forgive my ignorance, I don't know much
about VRML browser plugins. It looks like a 
problem with the JVM level being used
inside the browser to run the
VRML plugin.  
Can you tell me which browsers worked
or failed and the JVM levels of those that
were failing?

cheers,
Andy.

Subject	[aspectj-users] AspectJ classes in Cortona VRML Browser

Hello,

I've tried to use classes compiled with AspectJ in the Cortona VRML Browser
as 
part of the VRML file, but all I get is the following error message (repeated
quite often):

org.aspectj.lang.NoAspectBoundException: Exception while initializing 
EventOut: java.lang.IllegalAccessError: EventOut: field 
ajc$perSingletonInstance is final
        at EventOut.aspectOf
        at Movement.eventIn_timeChanged
        at Movement.processEvent
        at vrml/node/Script.processEvents
        at com/parallelgraphics/cortona/vrml/PassiveScriptImpl.callUser
        at com/parallelgraphics/cortona/vrml/PassiveScriptImpl.execute

The same aspect used in a standalone application works fine, so I suspect
it 
has something to do with using the Cortona engine.

The aspect looks like this (I've tried lots of other ones too):

public aspect EventOut
{
                
// this is for the cortona class
                
after() : call(public * Movement.*())
                
{
                
                 System.out.println("Cool
" + thisJoinPoint + " was hit!");
                
}
                
// this is for the standalone class
                
after() : call(public * TestClass.*())
                
{
                
                 System.out.println("Cool
" + thisJoinPoint + " was hit!");
                
}
}

I used the -target 1.1 compiler switches for both, the Cortona VRML class
and 
the standalone application, so this should not be the problem.

I have no idea how I could make them work together, any help will be 
appreciated.

Additional Note:
I have tested this with another browser and it worked, so it might be a
Cortona bug?


Background:
The Movement class is a subclass from the vrml.node.Script class which
is used 
to move some objects of the VRML scene around.


Greetings Ben
