Why is Jython not popular?

I think Jython wasn’t able to take advantage of its potential as an alternate JVM scripting language, not for any technical reason, but for marketing and product. For non-Java users, it doesn’t have benefits over the regular Python – and is lagging behind in version numbers.

Is Jython a compiler?

The jythonc tool generates actual Java source code, and then invokes a Java compiler over this source code to create the . class files. Thus, you will need access to a Java compiler in order to use jythonc. It is recommended that you use Sun’s standard javac compiler, or IBM’s excellent jikes compiler.
