Hi everyone,
I'm developing an application which will use load time weaving feature, so
that I can control whether my App classes should be weaved at runtime.
I read
http://www.eclipse.org/aspectj/doc/released/devguide/ltw-configuration.html,
learned AspectJ comes with the WeavingURLClassLoader probably can help me.
but there's no concrete example I can take a look, so could someone please
tell me how to use WeavingURLClassLoader? I have checked the source code,
there's 2
constructors available,
(1)public WeavingURLClassLoader (ClassLoader parent)
(2) public WeavingURLClassLoader (URL[] classURLs, URL[] aspectURLs,
ClassLoader parent)
Which one I should use? Could you please explain the meaning for the
parameters in detail?
Do I still need to use <iajc> to compile my aspect source code, and buit
them into a jar file, and pass the jar file URL to the constructor as the
second parameter?
or only package the source code as jar file, and WeavingURLClassLoader will
do all for me?
Thanks

Hi
What JVM version is this for? If its for JDK 5 then you just have to add
-javaagent:lib/aspectjweaver.jar as JVM startup parameter to enable
weaving

Hi,
I try to use around advice for a general use. I would like to use around for all the methods of a class which one does not know in advance the functions. For example, for a class A has which has 6 methods and a file aspectJ which defines a pointcut A.* for all the methods of A, is it possible to define a generic around for example:
pointcut methods (): execution (public A.* (...));
Object around (): methods () {
….
return proceed ();
}
knowing that the methods of A have different signatures ! I tested the code written above and it does not function, it never passes in the around method whereas with a before or an after for the same pointcut, it works very well. If somebody already had to deal with this problem, I am waiting your answers!
Cordially
Antoine

Hi.
As far as I can see this advice should be correct (in the sense that
it executes but has no visible effect on the program).

Your "methods" pointcut is missing the return type for the method and
you should have 2 periods for the method argument list:
> pointcut methods (): execution (public * A.* (..));
Actually, AspectJ might infer the return type. I always put it in the
definition. The 2 periods is important! 3 periods should give a
compilation error.
Also, make sure that "A" is visible without the fully-qualified
package name, etc. I don't believe that AspectJ will flag an error if
no "A" is visible, but you will get a warning that no join points were
advised.
