Re: [science-iwg] Fwd: ICE EASE Jython integration picture

Thanks Tracy! I'll try to reach out to him. As you say, having all of these different technologies working under EASE would be ideal.

Jay,

The Py4J developer is Barthelemy Dagenais -  Jonah recently worked contributed some features to Py4J based on work on autocompletion for DAWNSci. He was very good to work with just very very busy so took a while before he could review the feature.

While Py4J is very good for some things, it still does not cover all of DAWNSci requirements, hence the need for custom written AnalysisRPC. The talk we just did at Eclipsecon talk (slides here: https://speakerdeck.com/tracymiranda/integrating-python-and-java-in-eclipse) discussed the various technologies used.

In summary, lots of different technologies that could stand to work better together and be more accessible. I think EASE might be a good place to unify them - it's good to hear that there is already some work done towards non-JVM based languages.

Christian,

Who is the developer? Maybe we can get him talking again.

We are also experimenting with Py4J. The drawback of this framework is that the bridge is uni directional. Python can access java, but when you use java to launch a python script you only get a String object as a result. Had some email traffic with the developer some weeks ago. i guess it would be fairly easy to extend the API to allow to return Objects instead of strings. The contact with the developer broke off, so we are missing someone to implement this into Py4J. Afterwards we could safely integrate it into EASE to have full interoperability between Python and Java.

Jay,

 

That’s good, but dawnsci can get OSGi services in CPython aswell… J

Just saying is all J. The video gets the plotting service stub which is connected via py4j. Still the EASE stuff is handy and with OSGi Jython we might be on to a winner!

Everyone,

Here's a screenshot of EASE and Jython running in Eclipse ICE. It is creating a new MOOSE job to launch.
