Can Jython replace Java? [closed]

Question

So many server side and the mobile Java applications use the native Java language for Java. Can we use Jython instead to build the enterprise applications, e.g. websites, application servers etc.

Also what do you feel about Java ME applications in Jython.

P.S. Comments on question also welcome.

Answer 1

No, Jython is not a suitable replacement for Java. Consider, for instance, that it provides no way to implement interfaces without writing the interface in Java and then writing a class leveraging it in Jython.

What's needed is a JVM-targeted equivalent to Boo. Boo is a language targeting the .NET CLR which is roughly inspired by Python but not compatible, and which fully exposes the CLR's functionality (thus being feature-equivalent with C#). There presently is no Pythonic language with feature parity with Java -- and such a language would necessarily be incompatible with Python, as Python simply doesn't provide a way to express some of the relevant concepts (such as interface typing information).

Since there have been some questions about this, yet me clarify:

Jython is not a replacement for Java in the sense that you can't take an arbitrary Java project, decide to implement a random subset of that project in Jython instead, and not have anyone else on the development team know or care. Certainly, Jython is suitable for many of the same classes of projects that Java is, except when you're building an interface which will be called from Java, rather than the reverse. Given as "enterprise applications" tend to have a lot of components which operate closely with each other, being able to build a class with an arbitrary external interface is important... and is something which isn't readily done in pure Jython.
