Hi,
I think I am in the same boat as aschearer. I am just beginning at looking
at embeddable scripting languages. I see that it is possible to create New
java objects through Rhino and work with these objects. But is it possible
for Rhino script to interact with an existing running Java application?
For example,
I have a Java Application with a package with a class which has a private
variable int "count", a main function and another function called
jFunction(int num) { count += num; }
I run this application with Rhino embeded and then I would like to use Rhino
shell to call the jFunction from the running instance of the application
with the following script
function jFunctionCall(num) {
jFunction(num) // call the java function of the running application
}
jFunction(num)
calling this function would then add num to the count variable in the Java
object
Is this possible? I may be totally lost here at what Rhino can do. Please
let me know if you'd like me to clarify further..or if I am not making any
sense at all.
I guess the question comes down to, can I use Rhino as a command prompt /
command line interface to control my application.
Thank you very much for any help
Eric
