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);")
                .append("}")
                .append("myFunction();").toString();
        System.out.println(engine.eval(myJSCode));
    } catch (ScriptException ex) {
        ex.printStackTrace();
    }
}
