Command prompt that knows Java?

Question

Java REPL shell

Is there a project that makes a command prompt that can execute Java statements? Why not? I'm looking for something like the builtin shell of Python but for Java.

I see there is http://www.beanshell.org/ but that project does not seem very active. But it appears to be what I'm looking for. Are there any other projects like this?

I want to be able to do something like this

$ import org.foobar.Bletch

$ new Bletch();

or similar. Has anyone done this?

Without any offense, could you tell what you do you find in a java shell? — zeller, Aug 22 '12 at 13:08
How about [jython](http://www.jython.org/)? While this is actually a python shell built on top of java, you would be able to access all java features with it. So practically it's a java shell with python syntax and additional python features... — l4mpi, Aug 22 '12 at 13:08

You could always use a Clojure REPL - I do this for dynamically playing with Java objects at runtime.

(import 'my.package.SomeClass)

(def a (new SomeClass))

(.methodName a arg1 arg2)

Works pretty well as long as you know the Clojure syntax.

Or a Scala REPL, which has syntax that's closer to Java than Clojure. – Jesper Aug 22 '12 at 13:32

Look at Groovy Shell - this is not exactly Java, but very close.

You can use http://www.beanshell.org/

It is more than 12 years old and is used in a number of IDE's debuggers.
