Title: Message
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

How to use load time weaving?
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
