In the best case you only have to make sure your java classes
are on the class path when you invoke jython, and then
you can use them directly in jython. No conversion needed.

Like python, jython is not statically typed. You can use
anything at any place. You might get runtime errors,
but no compilation error (provided the syntax is correct.)

Yes. In case you want to access jython classes from java code
have a look at:
