Christian,

You probably want to look at the Clamp project (https://github.com/jythontools/clamp/), which supports the singlejar use case. See https://github.com/jimbaker/clamped for more details.

Incidentally, I will be at EuroPython, and Clamp is a major part of what I be discussing:
Lastly, I will also be at JavaOne where my colleague Werner Mendizabal and I have a presentation about related efforts to run OpenStack on the JVM, using Jython. In particular, we are working on a production deployment of the Keystone identity service using Jython, going against a Java backend that we have at Rackspace. We plan to use Clamp as part of this deployment process.

Hello everybody,

unfortunately I can't get it to work combining Python scripts, Java
classes and the Jython runtime in a single jar as mentioned in the wiki:
https://wiki.python.org/jython/JythonFaq/DistributingJythonScripts

I noticed the following with the released jars from version 2.7b2 (and
2.5.4rc1 too):


header for both:
Jython 2.7b2 (default:a5bc0032cf79+, Apr 22 2014, 21:20:17)
[Java HotSpot(TM) Client VM (Oracle Corporation)] on java1.7.0_60
Type "help", "copyright", "credits" or "license" for more information.


jython.jar from the regular installation (without Python standard
library /Lib inside jar):
>>> import org; dir(org)
['__name__', 'apache', 'ietf', 'jcp', 'omg', 'python', 'w3c', 'xml']
>>>


jython.jar including /Lib, like the standalone.jar:
>>> import org; dir(org)
['__name__']
>>>


So while the jython.jar allows adding Java classes and accessing them,
it won't work with the standalone.jar.

How can I have both, the /Lib and access to Java classes, in a single jar?

Thanks,
Christian
