Hi there,
After a few days, I finally managed to "marry" OSGi and Jython. Briefly, the PythonInterpreter needs a ClassLoader, which can handle the OSGi bundles. So here is a StackOverflow article with my question and my answer there:
http://stackoverflow.com/questions/31001850/passing-osgi-bundles-for-jython-interpreter-on-the-fly
And the essential code:

Hope this email might save time, when you need to integrate Jython into your projects :)

Hi,
the python sample scripts were provided quite some time ago, when the project was part of the e4 incubator.
We changed lots of the code base since then, but no one updated the python scripts.
Regarding the one you mentioned:
The module names changed a bit:
eg "ResourcesModule" is called "Resources" by now.
Have a look at the js sample file that does the same:
http://git.eclipse.org/c/ease/org.eclipse.ease.scripts.git/tree/_javascript_%20Snippets/Java%20helpers/Add%20println%20Tasks.js
To see what modules/functions are available have a look at the 'Modules Explorer' view.
If you need more support, best subscribe to the ease-dev mailing list or go to the forums.

Hi Christian,
thanks for pointing out that blogspot. I tried loadModule() today using the example here:
http://git.eclipse.org/c/ease/org.eclipse.ease.core.git/tree/plugins/org.eclipse.ease.lang.python.examples/samples/scripts/Find_System_Prints.py
However whenever I run this script as an EASE script I get the following error.
Unable to find module "ResourcesModule"
Unable to find module "WorkbenchModule"
I got similar errors with the other examples.
Jython version: 2.7b3 (default:e81256215fb0, Aug 4 2014, 02:39:51)
[OpenJDK 64-Bit Server VM (Oracle Corporation)]
What am I doing wrong? :-)
Best wishes,

Hi there,
nice you discovered EASE. Our Jython interpreter is a full featured OSGI citizen. You may import any Java class from the JRE and from all available OSGI bundles.
loadModule() is a command we inject into the Jython engine. It allows us to load libraries written in Java (it' s easy, see http://codeandme.blogspot.co.at/2014/10/writing-modules-for-ease.html ) which basically wrap java functionality to script functions. Call it a more convenient way for users to call the java world. Loading modules is not necessary to access java classes!
For Jython we would love to find a way to get numerics in. We are missing numpy scipy support deeply there, so if you have any solutions/worarounds for this problem we would be glad to bring them to EASE.
best regards

Jay, Matt,
Thanks for the replies. I am looking at the python examples in EASE. They use e.g. loadModule("WorkbenchModule"). Does this mean, that integrating EASE in our Ecliple RCP-based software I could reach the our OSGi bundles?
Best wishes,
Janos
