Hello Andy,
Thank you very much for your answer. I've studied your code. It does not
work from our side because we do not specify a particular class but all
classes from a specific packages. We use "com.nested.my.concurrent.*"
which means for us, If I do not make a mistake, all classes from this
package ? and then also the inner classes. But it seems it does not work
like this.
So the other question, does it mean we have to declare in a separate
aspect (physical file) to avoid such duplicate mixin because in the code
below, the class CiaWebThreadFactory has 2 mixins - One from the
"com.nested.my.concurrent.*" and the second from
"com.nested.my.concurrent.CiaWebThreadFactory.*"
Then does it means there is no syntax to targeted class and inner class
at the same time by specifying only "all.classes.from.this.package.*" ?
@Aspect
public class LoggingConcurrentBehavior extends LoggingBaseBehavior {
@DeclareMixin("com.nested.my.concurrent.*")
public static Loggable createLoggerDelegate(Object o) {
return new ServantLogger(o.getClass());
}
@DeclareMixin("com.nested.my.concurrent.CiaWebThreadFactory.*")
public static Loggable createLoggerDelegate2(Object o) {
return new ServantLogger(o.getClass());
}
Regards,
Jean ANDRÉ

Sorry I didn't reply earlier, I was at eclipsecon. I tried to scaffold
your situation but it just works for me. Are you loadtime weaving or
compile time weaving? Here is my complete code:
=== CiaWebThreadFactory.java
package com.foo.bar;
public class CiaWebThreadFactory {
public static void main(String []argv) {
new CiaWebThreadGroup().foo();
System.out.println("works");
}
static class CiaWebThreadGroup {
public void foo() {
Loggable cwtg = ((Loggable)new CiaWebThreadGroup());
cwtg.log("hello");
}
}
}
=== Loggable.java
package com.foo.bar;
interface Loggable {
void log(String msg);
}
=== ServantLogger.java
package com.foo.bar;
class ServantLogger implements Loggable {
public ServantLogger(Class clazz) {
System.out.println("ServantLogger for "+clazz.getName());
}
public void log(String message) { System.out.println(message);}
}
=== LoggingConcurrentBehaviour.java
package com.foo.bar;
import org.aspectj.lang.annotation.*;
@Aspect
class LoggingConcurrentBehaviour {
//works:
@DeclareMixin("com.foo.bar.CiaWebThreadFactory.CiaWebThreadGroup")
@DeclareMixin("com.foo.bar.CiaWebThreadFactory.*")
public static Loggable createLoggerDelegate(Object o) {
return new ServantLogger(o.getClass());
}
}
===
ajc -1.5 *.java -d . -showWeaveInfo
Mixing interface 'com.foo.bar.Loggable' (LoggingConcurrentBehaviour.java)
into type 'com.foo.bar.CiaWebThreadFactory$CiaWebThreadGroup'
(CiaWebThreadFactory.java)
Type 'com.foo.bar.CiaWebThreadFactory$CiaWebThreadGroup'
(CiaWebThreadFactory.java) has intertyped method from
'com.foo.bar.LoggingConcurrentBehaviour'
(LoggingConcurrentBehaviour.java:'void
com.foo.bar.Loggable.log(java.lang.String)')
and then when I run it:
java com.foo.bar.CiaWebThreadFactory
ServantLogger for com.foo.bar.CiaWebThreadFactory$CiaWebThreadGroup
hello
works
In terms of mixin pattern matching I was using:
@DeclareMixin("com.foo.bar.CiaWebThreadFactory.*")
and that was fine (as you can see from the weave info messages).
I tried AspectJ 1.7.2 and 1.6.12 - worked on both.
If you can perhaps edit my code to be more representative of your failing
sample, I could investigate further. I wouldn't be surprised if there were
inner class problems (I half expected my code to fail) but at the moment
I'm not having luck finding problems.
cheers
Andy

Hello,
A quick question, is it possible to declare Mixin (@DeclareMixin) in order
to have it in inner class ? If yes, we have difficulty to find the right
syntax.
We use aspectJ 1.6.12 under WAS 8.0.0.3
Here is our stuff - The mixin is perform well for the class
CiaWebThreadFactory but not for the inner class. We have tried different
syntax without any success.
Any help ? - and if we have several inner class, is there a shortcu to
catch all of them in a single syntax ?
Thank you very much.
