Integrating Python and Java in Eclipse


Python (specifically CPython) is heavily used in science, in part thanks to its fast powerful libraries such as numpy and scipy. It is still one of the best ways to handle and analyze numerical data today. While Python is for science, Java is for Eclipse but in industry there is a need for an optimal way to exchange data between the two.

This talks looks at various ways Java and Python can be integrated to give interoperability between Java, Eclipse based tools and Python modules. We look at the full spectrum of integration options, from loosely coupling tools to tight two way integration which involves technology such as PyDev, Jython, AnalysisRPC and Py4J.

Each type of technology has a particular sweet spot depending on the trade-offs of your application. This talk also takes a look at the Dawnsci project which utilizes a combination of these technologies to provide a powerful environment which seamlessly integrates Python and Java and gives scientists features such as the ability to perform operations in Python but visualize the results in Eclipse and code-completion of Java classes in a python console.
