No special setup. The dump output should go into an folder called "_ajdump" (the .class files before weaving will go into a subdir of that called _before). "_ajdump" is created relative to the current directory in which the application runs. A warning message should come out if there is a problem dumping, if you don't see that then the files should be somewhere... Sorry if I'm a bit vague, I'm a bit rusty on LTW at the moment ;)
