JSF 1.2 javascript execution from java bean code

Question

Hello I am trying all day to execute window.alert('aaa'); javascript from java bean code

I've tried all hints from: Calling a JavaScript function from managed bean

• cant use PrimeFaces 6.2+ because i don't have JSF 2.0
• cant use PrimeFaces 6.2- because I don't have JSF 2.0
• cant use Omnifaces because i don't have JSF 2.0
• JSF 2.3+ cant use because I do not have 2.3+
• JSF 2.2- does not work because h:outputScript is not used in JSF 1.2
• IceFaces JavaScriptRunner.runScript - cannot use because it automatically update jsf package to 2.0
• also tried FacesContext.getCurrentInstance().getResponseWriter().write("window.alert('aaa')"); but does not work

Iam using this dependency and cannot update. Also using richfaces 3.3.1.GA
