OSX Script execution error -10810 in mac

I am trying to run an OSX script to bring the browser to front for selenium execution, but failing due to below error.

javax.script.ScriptException: An error of type -10810 has occurred.
oasscript errorAn error of type -10810 has occurred.

Below is the code which I am using to run the script.

public void bringBrowserToFront() {
    try {
        String script = "tell app /"Google chrome/" to activate";
        ScriptEngineManager mgr = new ScriptEngineManager();
        ScriptEngine engine = mgr.getEngineByName("AppleScript");
    } catch (ScriptException e) {
        System.out.println("oasscript error" + e.getLocalizedMessage());


Could some one please let me know where I have gone wrong.

You need to specify the extension of the app.

eg: Google Chrome.app

String script = "tell app /"Google Chrome.app/" to activate";
