Compare dates using javascript engine
===

I am using Javascript engine to compare values. Values can be double or date. (strings)

    ScriptEngineManager factory = new ScriptEngineManager();
    ScriptEngine engine = factory.getEngineByName("JavaScript");
    // Date value is populated dynamically here
    engine.eval("dateValue = " + "01/02/2012");
    // The condition is populated dynamically here
    if ((Boolean) engine.eval("dateValue <=" + "12/31/2012")) { 
      System.out.println("TRUE");
    } else {
        System.out.println("FALSE");
    }


The above code works fine with double values, but gives wrong results with dates. For the above example it should display TRUE, but it displays FALSE. Please help.
