getServlet() is deprecated its corresponding replacement

Question

I am coding for my changes from Struts1 to Struts2. In this we find many instances where the getServlet is being used like the following code snippet. Now, getServlet() is being deprecated. I would like to know what to use instead. I tried looking at google a lot but no luck till now.

protected XXXServlet getYYYActionServlet() {
        try {
            return (XXXServlet)getServlet();
        } catch(ClassCastException ex) {
            return null;
        }
    }

Please provide your suggested course of action with example. Also, please let me know the remediation steps for processActionPerform() in Struts1.

Answer 1

Modified the answer, I am using core java concepts to get the instance of the servlet:-

    private static XXXServlet xxxServlet = null;

    public static XXXServlet getInstance() {
        return xxxServlet; 
    }

    public XXXServlet() {
        super();
        xxxServlet = this;
    }
