getting data from servlet class

I have a class that gets data from the servlet like so : 

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    response.setContentType("text/html");{
        ServletOutputStream  out = response.getOutputStream();
        try {
            out.println("<html><head><title>" +  "</title></head>");
            out.println("<body><h1>" +  "</h1>");
            name = request.getParameter("username" );
            message = "hi there";
            //String  comment = request.getParameter( "comment" );
            out.println("Name:" + name + "<BR>");
            //out.println("Comment: " + comment + "<BR>");
        }
        catch(Throwable  t ) {
            out.println("<P><pre>");
            t.printStackTrace( new PrintStream(out) );
            out.println ("</pre><P>");
        }
        out.println ("</body></html>");
    }
}

And that works fine, but I want to use the name parameter in a different class on the server too. Can I use something like : 

getServletContext().setAttribute("package", "name");

And call the attribute from the class like that? Or is there another way I can save the value in the servlet context or in the servlet so I can call it again? all i really want to do is after the servlet is loaded, to keep the last value it's processed somewhere and use that in another class when needed.

All Help is appreciated!! :)

getServletContext() is one of the ways to share data between servelts. So, yes your approach should be fine.

If the data is specific to user, instead of getServletContext(), it is better to use HttpSession.
