Fabian,
The recommended approach to binary weaving is to maintain the original modularity of the application i.e. weave each JAR file separately and (optionally) give each one a modified name. This will avoid difficulties deploying and configuring the application.The definition of a cross-cutting concern and the packaging of the affected application should be orthogonal.

Hi,
thanks for your prompt help.
As I see there is no direct way to get only the affected classes. So I have to
think about a workaround here.
A .class scanner might be one solution. Or you take the weaveInfo string and
extract the class information from it to copy only affected files. This could be
done in a self written Ant task...
regards,
Fabian
