Thanks for the anwer.
At the moment I've unzipped the pear so, and the AAE descriptor points 
to the two directory. Maybe I've written a bad java code, but it's 
copied from another project where I used one of the two unzipped simple 
AE and it works fine.
What is the right way to call an AAE from a java sofware?

Thanks

Andrea
