Re: [science-iwg] About java-python integration

[Marek Jagielski <marek.jagielski@xxxxxxxxx>]

In my case (https://www.youtube.com/watch?v=qvY3V9Ujoa0) I enabled two ways of java-python integration. 

One is via Jython. However, in this solution it would be hard to use numpy, etc.

Second one is running a separate python process from Java and establish bidirectional communication using thrift (https://thrift.apache.org/). I used on the python side thriftpy library (https://thriftpy.readthedocs.io/en/latest/). However, you are limited to predefined data types. In some situations, I had to do objects serialization to binary type and restore them on the second side.

Best,

Marek

Hi Michele,

you may have a look at this slides:

or the DAWNSci workbench:

Hi,

recently I was looking around for a handy solution to setup bidirectional communication between Java and Python. I know that this is not a trivial issue. However, looking at the past EclipseCon presentations, I noticed that jpy libraries (licensed under GPL3) have not been mentioned.

http://jpy.readthedocs.io/en/latest/intro.html
https://pypi.python.org/pypi/jpy/

Do you know any reason that might discourage to implement them?
Do anyone has any experience with these libraries?

Cheers,

Michele.
