I will try it tomorrow at work. But one question before.
I'am new to the JBoss 7 module technology and I think that when I work with a jar deployment then I have to declare all library dependencies in my
META-INF\jboss-deployment-structure.xml
Your recommended option one means that I should add the snowdrop-weaving jar to the classpath by my maven pom.xml. I'am not sure how it works.
