Calling Python code from Java by passing parameters and results

Try using Java ScriptEngine

to run your code like Jython.

Sample program:

import javax.script.ScriptEngine;
import javax.script.ScriptEngineManager;
import javax.script.ScriptException;

public class Main {

     /**
     * @param args the command line arguments
     */
    public static void main(String[] args) throws ScriptException {
        ScriptEngine engine = new ScriptEngineManager().getEngineByName("python");

        // Using the eval() method on the engine causes a direct
        // interpretataion and execution of the code string passed into it
        engine.eval("import sys");
        engine.eval("print sys");

        // Using the put() method allows one to place values into
        // specified variables within the engine
        engine.put("a", "42");

        // As you can see, once the variable has been set with
        // a value by using the put() method, we an issue eval statements
        // to use it.
        engine.eval("print a");
        engine.eval("x = 2 + 2");

        // Using the get() method allows one to obtain the value
        // of a specified variable from the engine instance
        Object x = engine.get("x");
        System.out.println("x: " + x);
    }

}

      

        
        
        
      

    

You will need to include the jython jar jar in your classpath. find here
