[Jython-users] JSR-223, Jython 2.5.1 and implementing Java Interfaces from Python

Hi there,

TL;DR: Calling methods from an embedded Jython script does nothing when
using JSR-223 and Jython 2.5.1, while Jython 2.2.1 just works fine.

[Disclaimer: This is my first post on this list, so please go easy on me
:-)]

I'm currently trying to switch to Jython 2.5.1 from 2.2.1 and I'm having
a real hard time getting it to work...
Naively, I would've thought that replacing jython.jar with a new one
from 2.5.1 and removing jython-script.jar would just work.
I'm using the JSR-223 interface to embed the scripting engine. By
itself, everything seems to work as expected and the same way as in
Jython 2.2.1 (apart from the newer language that is).
The only thing that is not working for me is implementing a Java
interface from Python and calling methods on it. I have created a small
test program for this:

- ------------- myscript/ScriptingTest.java -------------
package myscript;

import java.io.InputStream;
import java.io.InputStreamReader;

import javax.script.ScriptEngine;
import javax.script.ScriptEngineManager;

public class ScriptingTest {
    public static void main(String[] args) {
        try {
            final ScriptEngineManager manager =
                new ScriptEngineManager();
	    final ScriptEngine engine =
                manager.getEngineByName("python");
	
	    final InputStream is =
                ScriptingTest.class.getResourceAsStream(
                        "/myscript/myscript.py");
            engine.eval(new InputStreamReader(is));
        } catch (final Exception e) {
            e.printStackTrace();
        }
    }
}
- ------------- myscript/PythonCallable.java -------------
package myscript;

public interface PythonCallable {
    String getAString();
    void callAVoid();
}
- ------------- myscript/myscript.py -------------
from myscript import PythonCallable as PythonCallable

class MyPythonCallable(PythonCallable):
    def getAString(self):
        return 'A string'

    def callAVoid(self):
        print 'Called a void method'

print 'getAString() returns: %s' % \
    MyPythonCallable().getAString()
print 'callAVoid():'
MyPythonCallable().callAVoid()
- ------------------------------------------------

Using Jython 2.2.1, I get:
  $ java -cp .:jython.jar:jython-engine.jar myscript.ScriptingTest
  getAString() returns: A string
  callAVoid():
  Called a void method

This is just the way I would expect things to behave (OT: embedding
JavaScript and using a similiar script gives similiar output).

Using a Jython 2.5.1 JAR, as created by the installer (with the default
options), I get this instead:
  $ java -cp .:jython.jar myscript.ScriptingTest
  getAString() returns: None
  callAVoid():

I also tried Jython 2.5.2 RC2 with the same result.

If it matters: my environment is Debian Linux 5.0 AMD64 with the Sun
Java 1.6 JVM, Windows seems to behave the same way.

Am I doing something fundamentally wrong? Is using JSR-223 this way
supported at all in Jython 2.5.1? If I missed relevant documentation,
can somebody point me in the right direction?

Cheers,

Jython 2.5.1 has serious JSR-223 issues -- use 2.5.2rc2 instead. Come 
back here if it still doesn't work.

Oops...sorry :(
I'll try running those and see if I can figure anything out.

Works fine for me. Jython 2.5.x contains its own JSR-223 engine so don't 
try to use the old engine jar with the new Jython. That leads to...well, 
you already know ;)

Mind you, using Jython itself works as expected, only interfacing with
Java doesn't work for me.

Same result with Jython 2.5.2 RC2, sorry:

                 +--- Jython 2.5.2 RC2 (full)
                 v
$ java -cp .:jython.jar myscript.ScriptingTest
getAString() returns: None
callAVoid():

Just tried with Windows 7 x64 and Java 1.6.0_22, also same result:

C:\TEMP>java -cp.:jython.jar myscript
getAString() returns: None
callAVoid():

Anything else I can do? I'd rather not use the interpreter directly and
only go through the JSR-223 API, since the application I'm embedding
Jython in also has to support Jruby and JavaScript and using a different
API would be a pain, maintenance and testing wise.

I'll also try with the latest trunk version to see if that changes
anything (I'll have to build it first, so it might take a while).

Thanks for you quick replies, guys.

Any news? Is there some bug id or something assigned to the issue (so I
can track it there instead of bothering you guys)?

Hi Christian,

you are right, no news so far.
I opened the following ticket: http://bugs.jython.org/issue1681
and I'll try dive into it.

best wishes,
