Re: [Jython-users] Import/Use Jython class and method in Java

[Pierre T. <pie...@gm...>]

Thank you Josh. I am reading The Definitive Guide to Jython. I really like
it. The only thing I dislike is the covering about how to use Jython code
from the Java side. The chapter 10 on this subject gives some examples but
it does not go deep enough for me. What I believe is missing is how to match
the Jython types and Java types. Like the "PyString" in the code examples, I
don't know where this is coming from.

When I'll finish the book, I'll do a review for Apress. I didn't buy the
book, I received it from Apress. I'll write a positive review of course :-).
