http://www.eclipse.org/aspectj/doc/next/weaver-api/org/aspectj/weaver/loadtime/WeavingURLClassLoader.html.
Here is a little old code snippet I found in one of my projects when I
implemented a plug-in concept in which I had the aspect code in my main
project, but wanted to advise plugin JARs which were loaded on demand. Feel
free to modify it according to your needs:
private void loadPlugin(String pluginJar, String pluginClassName)
throws Exception {
echo("Trying to load plugin JAR " + pluginJar);
ClassLoader loader =
Thread.currentThread().getContextClassLoader();
WeavingURLClassLoader weaver = new WeavingURLClassLoader(
new URL[] { new File(pluginJar).toURI().toURL() },
new URL[] { loader.getResource(".") },
loader
);
Class<?> pluginClass = weaver.loadClass(pluginClassName);
Plugin plugin = (Plugin) pluginClass.newInstance();
plugin.init(this);
plugins.add(plugin);
echo("Successfully loaded and initialised plugin '" +
plugin.getName() + "'");
}

Subject: [aspectj-users] Runtime weaving without agent
> Hi,
>
> I'm maintaining a project that is still using unmaintained
> aspectwerkz project. It's now time to move on ;)
>
> In this project, we are using a custom classloader "per thread"
> which "weave" class on the fly when class is loaded
> (Classloader#findClass(String)). [1]

> Since aspectj and aspectwerkz join forces in 2005, i'm trying

> But, i can find only documentation using agent [2], which is not
> possible in our use case.

> Is it still possible to do it with only runtime programmatic way ?
