JSP function output in wrong location ? Why?

Question

I have a weird problem ..

That is , in my program, a called a function after body tag. But the output comes in unexpected location that is above html tag !!!

Program : JSP page [server]



    <%
         if (request.getParameter ("query") != null)
         {
         String query2 = request.getParameter ("query");
         String srch2 = request.getParameter("searchby");
        SimpleSuggestionService smp =new SimpleSuggestionService ();

         if (!srch2.equals("No")) 
         {
       //below the mentioned out function call
       smp.Suggest(response.getWriter(), query2,config.getServletContext().getRealPath("/")+"WEB-INF/wordlist/spin/",config.getServletContext().getRealPath("/")+"WEB-INF/wordlist/whole_2_2.txt");
          out.println ("hello");
}      
         }

         else out.println("suggestions :");
         %>

In the above program , the output of the function smp.Suggest(...) have to printed inside body tag.

but it printed above HTML tag starting !!
