Script arrays are accessed via JSObject as well. You've
JSObject.get/setSlot methods to access array elements. Array length can
be accessed using JSObject.getMember("length")

To: [email protected] <mailto:[email protected]>
Hi guys,
I have resolved the earlier error that I reported, I thought I was
using the correct jdk but then I wasn't and switching to the latest
version of the OpenJDK (nashorn) source and then bootstrapping to the
image created by the build process fixed it (hinted by you) - thanks
for that.
I'm now able to access the member elements, returned by Javascript
through the JSObject. Although the JSON I created also contained an
array of string elements, which I wasn't able to access but got
[object Array] when I printed it to console.
I tried casting it to org.json.JSONArray but it was of no use. Then I
came across the link
http://cr.openjdk.java.net/~hannesw/8007060/webrev.01/src/jdk/nashorn/internal/objects/NativeFunction.java.html
<http://cr.openjdk.java.net/%7Ehannesw/8007060/webrev.01/src/jdk/nashorn/internal/objects/NativeFunction.java.html>,
and applying the checks on the object to see if it can be converted or
not I got the output:
function.apply.expects.array (didn't pass any of the checks, and
terminated at the last else).
Is there a JSONArray object within the nashorn package that I could
use? Do you have any other example for that?
Thanks.
Regards.
Mani

Thanks Sundar, Jim for the explanation.
I extracted the jsobjectTest() from ScriptEngineTest.java as it is
and compiled and ran it, when I run it I still get the same error
that I got with my example. I have put all of this in a gist to
demonstrate what I was doing:
https://gist.github.com/neomatrix369/5731520
I also ran the ScriptEngineTest using the jtreg command and that
ran successfully:
~/jtreg/linux/bin/jtreg -jdk:/usr/lib/jdk1.8.0
-Xbootclasspath/p:$HOME/sources/jdk8_tl/nashorn/dist/nashorn.jar
-verbose:fail test/src/jdk/nashorn/api/scripting/ScriptEngineTest.java
