You don't. You deploy the class-files and they are purely Java compliant.

You might wanna use an around advice that "shadows" your actual method,
saves a timestamp before execution of this shadow, then invokes the shadow
using proceed() and finally reports the timestamp-difference.

I am not an expert on J2EE but I could not think of any issues here since
AspectJ is doing purely compliant bytecode transformations. They are of
course J2EE compliant as well.
