Parse org.mozilla.javascript.NativeDate in Java.util.Date

Question

I'm trying to parse a date that i get from JavaScript script evaluated with rhino library into java.util.Date, can i convert a org.mozilla.javascript.NativeDate into a java.util.Date ?

If convert NativeDate into a string with the Context.tostring method i get a date in the following format :

Wed Oct 12 2011 16:17:59 GMT+0200 (CEST)

How can i parse this string date representation in to a java.util.Date object ?

In Rhino use

context.jsToJava(nativeDateObj, Date.class);

In case anyone wondered, that is a static method, you don't need access to the script context. – Michael Böckling Aug 01 '14 at 15:40

Bvesco's answer works well. However doing this the other way round (java to js) is not entirely as simple - Context.javaTojs() does not work for dates. I eventually found the solution here - use the javascript constructor:

Object js = context.newObject(scope, "Date", new Object[] {date.getTime()});

The above post also mentioned the following alternative to convert a date from js to java (I haven't confirmed this):

Date date = new Date((long) ScriptRuntime.toNumber(s));

Using the javascript constructor works when going to JS. Thanks! – bigspotteddog Apr 05 '13 at 04:19

The method valueOf(String) is undefined for the type Date – aleroot Oct 12 '11 at 14:51

Undefined? The method exists in SE Java: http://download.oracle.com/javase/6/docs/api/java/sql/Date.html#valueOf(java.lang.String) – lynks Oct 12 '11 at 20:38
The method still exists in 7: http://download.oracle.com/javase/7/docs/api/java/sql/Date.html#valueOf(java.lang.String – lynks Oct 12 '11 at 21:15

ok, the method is in the java.sql.Date package, but it doesn't work, if i try to parse that string i get : java.lang.IllegalArgumentException. HAve you tried to parse the string in the post ? – aleroot Oct 12 '11 at 21:15
it should be obvious that you will need to parse the string somewhat – lynks Oct 12 '11 at 21:20
