there is one more style.css is there but it is not showing anything while execution note all source file is present in same folder please tell me where am lacking

According the documentation of autocomplete, you need a javascript json object. This is a container for all your data. I miss this container in your source code which you have posted.

If you click on Demos of utocomplete, scroll to the end of this page. I think the last demo represents what you look for.

<% 
 String countries[] = {"Afghanistan","Albania","Algeria","Andorra","Angola","Antigua and Barbuda","Argentina","Armenia","Yemen","Zambia","Zimbabwe"};
 String query = (String)request.getParameter("q");
 response.setHeader("Content-Type","text/html"); 
 String javascriptContent = new String ("");
 int cnt = countries.length;
 if(cnt > 10)
 {
  cnt = 10;
 }
 for(int i=0;i<cnt;i++)
 { 
    if(countries[i].toUpperCase().startsWith(query.toUpperCase()))
    {
        javascriptContent.concat(countries.get(i));
        if (i < (cnt -1))
        {
            javascriptContent.concat(",");
        } 
    }
} 
%>

Here they are and have fun. I copied athe html source code from the mainpage of autocomplete. Please check the java syntax first.
