Hi Owen, This indicates that the before advice is in fact applying in
your test. Could it be that you aren’t seeing log output because the Log4jExecutionTracing
aspect traces to a log4j logger at debug level, and that you need to enable
debug output in your log4j configuration? From:

parents is or is not working? Andy. 2008/10/15 Owen Corpening <owencorpening@xxxxxxxxx> Probably a syntactical error,
the before() in Log4jExecutionTracing never gets executed, I bet my
"declare parents" isn't right, first time I ever came across that, I
guess I haven't been keeping up with aj1.5: package com.AjlibTest; import org.codehaus.ajlib.util.tracing.Log4jExecutionTracing; public aspect TestTraceAspect
extends Log4jExecutionTracing { declare
parents: com.AjlibTest.DummyObject implements Traced; } my package looks like this: ./com/AjlibTest/DummyObject.java ./com/AjlibTest/HelloWorld.java ./com/AjlibTest/TestTraceAspect.aj Anyone see my goof? thanks, owen ----- Original Message ---- Sent: Tuesday, October 14, 2008
12:00:12 AM Hi Owen, Traced is a protected interface
that is defined within Log4jExecutionTracing itself. You just use the aspect by
extending it and using declare parents to make the relevant classes you want to
trace implement traced, as in: public aspect
MyLog4jExecutionTracing extends Log4jExecutionTracing {
declare parents: com.bigboxco.myapp..* implements Traced; } From: aspectj-users-bounces@xxxxxxxxxxx
[mailto:aspectj-users-bounces@xxxxxxxxxxx]
On Behalf Of Owen Corpening With regards to ajlib: There is a
class Log4jExecutionTracing not covered in the unit tests and for which
there are no examples of its usage. It uses a class called "Traced"
that I don't see anywhere and I *think* that is at the core of my not
comprehending how to use this class. Basically if I have a test
tracing aspect like this it works great (DummyObject is the class whose methods
are to be traced): package com.AjlibTest; import
org.codehaus.ajlib.util.tracing.ExecutionTracing; public aspect TestTraceAspect
extends ExecutionTracing { public
pointcut scope() : within(DummyObject); before():
scope() {
System.out.println("Tracing"); } } But if I
change ExecutionTracing to Log4jExecutionTracing it doesn't weave anything
(advice defined in com.AjlibTest.TestTraceAspect has not been applied
[Xlint:adviceDidNotMatch]). much appreciated, Owen
