Py4J on Eclipse

[Naz Alan]

Hello,

i'm currently developing a python program and would like to access data from Java using Py4J. I would like to use Eclipse instead of NetBeans to do this. I had a success running the program using NetBeans but have difficulty using Eclipse. 

According to Py4J documentation, I need to install some plug-ins before I can run Py4J on Eclipse. Since i'm a complete begineer in Java and Eclipse, could anyone please tell me all the steps I have to do in order to install the plugins and run py4j on eclipse.

I'm trying to run a single additional function on Py4j, this is what the code looks like (on NetBeans): 

package py4j;
public class Py4j {

public int addition(int first, int second, int third) {
    return first + second + third;
  }
  
    public static void main(String[] args) {
     Py4j app = new Py4j();

    GatewayServer server = new GatewayServer(app);
    server.start();
    }
}

Any help would be much appreciated! Thank you so much.

Best Regards,

Naz

Hi Naz

Please look at the Eclipse EASE project. It fully integrates py4j into Eclipse.

https://www.eclipse.org/ease/

I did an in person tutorial on this a few years ago, the reference may still be useful to you. I updated the setup instructions of the tutorial about a year ago so hopefully that will work for you.
