Run it with all the flags set for debug and trace:
-Daj.weaving.verbose=true -Dorg.aspectj.weaver.showWeaveInfo=true
-Dorg.aspectj.tracing.messages=true -Dorg.aspectj.tracing.enabled=true
-Dorg.aspectj.tracing.factory=default
You will see trace but also 'I' entries which are info messages from the
weaver. The setup would be that you need the aspects on the aspectpath and
and on the classpath, there is no aop.xml required as you are directly
telling the weaver what the aspects are through the constructor. I just
tried it and it worked for me:
public class Sample {
public static void main(String[] args) throws Exception {
URL[] cpath = getClasspath("foo.jar", "aspects.jar");
URL[] apath = getClasspath("aspects.jar");
WeavingURLClassLoader wucl = new WeavingURLClassLoader(cpath, apath,
Thread.currentThread().getContextClassLoader());
Class foo = wucl.loadClass("Foo");
Method m = foo.getMethod("m", null);
m.invoke(foo.newInstance(), null);
}
public static URL[] getClasspath(String... files) throws Exception {
URL[] urls = new URL[files.length];
int pos = 0;
for (String file : files) {
urls[pos++] = new File(file).toURL();
}
return urls;
}
}
In the verbose output from tracing I see:
12:09:05.578 main I [WeavingAdaptor] info AspectJ Weaver Version DEVELOPMENT
built on Tuesday Oct 21, 2008 at 18:57:36 GMT
12:09:05.812 main I [WeavingAdaptor] info adding aspect library:
'C:\asc\ws\aspectj16_2\A\aspects.jar'
12:09:06.312 main ? [WeavingAdaptor] weaveinfo Join point
'staticinitialization(void Foo.<clinit>())' in Type 'Foo' (Foo.java) advised
by before advice from 'X' (aspects.jar!X.class:2(from X.java))
And my advice runs.
