Re: Javascript object to Map

[A. Sundararajan]

Hi.

Yes, that is expected. A nashorn script object is not a java.util.Map. 
You've to walk through each property and put prop-name-vs-value into the 
Map. Something like:

var obj  = { key1: value1, key2: value2 };

for (i in obj) {
    map.put(i, obj[i]);
}

Hope this helps,
-Sundar

Hi,

Reading the point 3.10 from this link:

If I didn't misunderstand that, if I have a javascript object I can pass it
to a java method that accepts a java.util.Map.

So, this code is supposed to work:

[code]

var HashMap = Java.type("java.util.HashMap");

var map = new HashMap();

map.putAll({key:"value",key2:"value2"});

[/code]

But when executing this using the jjs I got this error:


*"Exception in thread "main" java.lang.ClassCastException: Cannot cast
jdk.nashorn.internal.scripts.JO to java.util.Map"*

Is this the expected behavior?

Thanks,
