I recently had to deal with the same problem, some bi-directional
communication between Java and Python. Several options were discussed
between me and my fellow programmer. In the end we settled for XML-
rpc. It works remarkably well in our case. We use it to pass test and
simulation data to GUI code. XML-rpc is very well supported in python.
Basic types (lists, dicts etc.) are encoded automatically. If the
arrays are very large, I would probably use an intermediate database
(e.g. Hdf5) for storage and then use some sort of messaging to inform
the Java code of any changes.
