retrieve all interfaces in jar static possible

[Petterson Mikael]

Hi,

I am curious to know if it is possible to extract all interfaces (
including methods and fields) from my jar. I know of refelection but
AFAIK the class has to be loaded in the jvm to use reflection on it.
True? Is there a static possiblity?

If no static possibility then will all my classes in jar be loaded when
I start my jvm ( java -jar myapp.jar). Is it possible to 'extract' all
classes ( to be put in a list) and run refelction on them?

Cheers,

//Mikael

And then if you want to extract the data from those entries in the Zip
file without actually loading them into your VM you might want to look
