basic questions for Rhino
javanewbie
Call Java class's method from Javascript
What I did so far:
1) I downloaded rhino1_7R2
2) added js.jar (this was located right under directory rhino1_7R2) to
my project library
3) created fooclass with ScriptableObject
Problems I am getting
I am getting an error
var pn = new Packages.foo.foo.fooclass();
Error message from FireBug:
uncaught exception: Error calling method on NPObject! [plugin
exception: java.lang.ClassNotFoundException: foo.foo.fooclass].
Disclaimer:
Pardon me if this question might be too simple to ask on this forum..
Any help would be greatly appreciated.
thank you,

I am running into some problems and I was wondering if anyone can shed some
light for me.

Pardon me if this quesiton is too basic. I just found out about this Rhino
few days ago and I've been trying to get this foo example to work..
Any help would be appreciated.
thank you,

By "3) created fooclass with ScriptableObject," I meant I extended
fooclass with ScriptableObject
Please email me if any of my poins are unclear.
thank you,

Do you want to call (from JS) a method on a Java applet from running in
Firefox? If so, then you shouldn't need Rhino/ScriptableObject at all.
Methods on your the applet object will be reflected on to the <object>
or <applet> object in the DOM.
(I just guess that you're using Java applets/Firefox because you mention
Firebug.)
If you're trying to do something else, please explain in more detail.

I want to call Java method (not on applet, public method that exists
in a package) from js embeeded inside servlet. Is it possible? If so,
how?
If it's not possible, I want to call Java method (not on applet,
public method that exists in a package) from js embedded in a jsp. Is
it possible? If so, how?

that will ofcourse not work then rhino will not be used at all
You can exactue that embedded rhino js script only on the server

I have some procedure (written in java package) that takes about 10
min to run and it keeps track of how many more minutes left before it
complets its task (MinutesLeftToComplete).
I woud like to show on UI this MinutesLeftToComplete. Without having
to reload page, would there be any way to show MinutesLeftToComplete
on UI and updates the value on UI?
I thought that javascript is a way to go.. but any other suggestions
would be appreciated.
thank you!
