Help needed to Intercept and overide getter and setter method calls

Hi All,

I have a weird requirement and pretty new to bean shell (I have been playing 
with it for couple of days)

I am having the following code.

------------------------------------------------------

import java.util.Properties;

import bsh.EvalError;
import bsh.Interpreter;

public class PropertyTest {
    public static void main(String[] args) throws EvalError {
        Properties property = new Properties();

        property.put("value1", new Integer(2));
        property.put("value2", new Integer(3));
        property.put("value2", new Integer(0));

        Interpreter i = new Interpreter(); // Construct an interpreter

        i.set("property", property);

        i.eval("property.value3 = property.value2 * property.value1;");

        // I want to intercept the calls to Properties getter and setter 
values and call the Property.get("value1") etc
        // Can I do it? If yes, please tell me.

        //The following line should print 6
        System.out.println("The value3:" + property.get("value3"));
    }
}

------------------------------------------------------

Basically, what I want is to intercept the getter and setter called by bean 
shell and translate it to properties.get("value1") or 
properties.get("value2") or properties.set("value3", value)

Is it possible? How would I go about it.

One option I figured out is to create commands for set and get and use it to 
set and get values. But the expression would have to change it to some thing 
like

set(property, get(property, "value2") * get(property, "value1"));

But my requirement is to let the user define it as in code above 
["property.value3 = property.value2 * property.value1;"]. Please help.


Thanks in advance,
_Jp
