Rhino Evaluating a javascript object in Java

Question

Im quite new to Rhino and trying to convert a javascript object to a java object but unable to do so. It doesnt seem to evaluate properly.

The javascript that I have is,

var myObject = new Object();
myObject.string1 = 'Hello';
myObject.string2 = 'World';
myObject.id = 1;
var parser = new Packages.com.MyParser();
var returnStr = parser.PrintObj(myObject);

And I have the following java class that I want to evaluate this to,

public class Person extends ScriptableObject {
 private int id;
 private String string1;
 private String string2;
 public Person() {}
 public void jsConstructor() {
 this.string1 = "";
 this.string2 = "";
 this.id = 0;
 }
 public int getID()
 {
 return this.id;
 }
 public void jsSet_id(int value)
 {
 this.id = value;
 }
 public int jsGet_id()
 {
 return this.id;
 }
 public String jsGet_string1()
 {
 return this.string1;
 }
 public void jsSet_string1(String value)
 {
 this.string1 = value;
 }
 public String jsGet_string2() {
 return this.string2;
 }
 public void jsSet_string2(String value)
 {
 this.string2 = value;
 }
 @Override
 public String toString() {
 return id + " " + string1 + " " + string2;
 }
 @Override
 public String getClassName() {
 return "Person";
 }

And the skeleton of my parser is,

public class MyParser {
 public String PrintObj(ScriptableObject obj) {
 // Need to convert to Person object here
 // Obviously casting doesnt work here
 return null;
 }
}

Thanks

OK figured it out !

First of all i needed to define the class in javascript as. It was complaining at first it couldn't find the class without the namespace "com". Had to add that...

defineClass("com.Person")
var myObject = new Person();
myObject.string1 = 'Hello';
myObject.string2 = 'World';
myObject.id = 1;
var parser = new Packages.com.MyParser();
var returnStr = parser.PrintObj(myObject);

And then in the parser I added the following,

public String PrintObj(ScriptableObject obj) {
 try {
 Person pObj = (Person)Context.jsToJava(obj, Person.class);
 System.out.println("Printing person: " + pObj);
 }
 catch (Exception e) {
 e.printStackTrace();
 }
 return null;
}
