Yes, you can retrieve the function from the scope and call it, which
should be much faster than compiling a new script to do that. The code
would look something like this (Callable being the
org.mozilla.javascript.Callable interface, not the one in
java.util.concurrent):
Callable fn = (Callable) ScriptableObject.getProperty(scope, "myfun");
Object result = fn.call(cx, scope, scope, new Object[] {"hello
world"});
