Hi all,

I wonder which area do i need to research on for this problem.

Right now i want to invoke some javascript function in the java
program.

For e.g.

String result = evalExpression(" "Hello World".toUpperCase() ");

public String evalExpression(String javascript){
evaluate the javascript string and return the result
}

Appreciate any advice

Java has no eval, but I think JPython does, and possibly Ruby. You
could use on-the-fly compilation to cook one up for Java.
