I'd like to get the result of a javascript method (executed in a web

Yes it is possible. Take a look at the javax.script package (which exists
since Java 6).

Here is an example, executing a JS method called "myFunction" :

public static void main(String[] args) {
    try {
        ScriptEngineManager mgr = new ScriptEngineManager();
        ScriptEngine engine = mgr.getEngineByName("JavaScript");
        String myJSCode = new StringBuffer()
                .append("function myFunction() {")
                .append("return (4 + 5);")
    } catch (ScriptException ex) {

Ah. That is also a possibility.

I read it as calling some JS embedded in the HTML, but it
could also be embedded in (or fetched by) Java.

And since the embedded JS can use Java classes, then the forms
of JS can actually interact using Java as glue.
