[jboss-user] [JBoss AOP] - Aspect scope and construction pointcuts
AOP 1.5.2 libs being used
I'm having problems with construction pointcuts and PER_INSTANCE scope. All other
scopes work as expected, but it is PER_INSTANCE that I need.
@Aspect(scope=Scope.PER_INSTANCE)
public class MyAspect {
private static final Logger log = Logger.getLogger(MyAspect.class);
@Bind (pointcut="construction(public MyAspected->new())")
public Object constructorAdvice(ConstructionInvocation invocation) throws Throwable {
Object master = invocation.invokeNext();
log.info("Constructed Aspect");
return master;
}
}
--
public class MyAspected {
private static Logger log = Logger.getLogger( MyAspected.class );
public MyAspected() {
log.info("Constructed");
}
}
--
public class TestMyAspected extends TestCase {
static {
BasicConfigurator.configure();
}
public void testMyAspected() {
MyAspected ta = new MyAspected();
}
}
All scopes work correctly except PER_INSTANCE. With that scope, I get a nasty exception
which looks like the AOP framework couldn't find the Advice for the aspected
constructor.

Any ideas?
