You can not get all contained packages and classes, you can get a
good approximation if you dont care about strange class loaders.
For a good approximation:
Look up the classpath, check all directories and jar/zip files in it.
For each directory: check if you have any *.class files in it, go down
in every directory and start over.
For each jar/zip file: open it and check what files it contains,
files that are called *.class are good candiates
You will have to filter out inner classes and such things...
If you have a project that uses an URL class loader (loads the class
from the internet, then this will not work, you will not be able to
search the internet) or a Random class loader (generates a class from
a ranom number generator (I have not seen this, but in principle it
could come upt))....
