How To Pass the Request Scope To Another Class

Question

In my ListThread class, I first retrieve some of the text fields; i.e., request.getParameter( ... );
Thereafter, I want to pass the request scope together with some parameters to another class; SiteUtil.java., for some further processing. This is what I do:
public final class ListThread extends HttpServlet
      public doPost( HttpServeltRequest request, HttpServlerResponse response)
                  throws ServletException, IOException
      String offset = request.getParameter( "offset" );
      String size = request.getParameter( "size" );
      SiteUtil.prepareNavigate( request, offset, size,
           MessageInboxConfig.ROWS_IN_THREADS );
}This is my SiteUtil.java:
import javax.servlet.http.HttpServletRequest;
public class SiteUtil
   public static void prepareNavigate  
     (HttpServletRequest request, int offset, int   
                     collectionSize, int totalRows)
      int startOffset = offset + 1;
      int lastOffset = offset + collectionSize;
      request.setAttribute("StartOffset", new Integer(startOffset));
      request.setAttribute("LastOffset", new Integer(lastOffset));
}Can I pass the request scope and save attributes in the scope this way?

Answer 1

You can pass the request to that method as a parameter, yes, and you can even modify the request there. The request is just an ordinary Java object, so ordinary Java rules apply. Your code looks fine to me too.
However don't try to store the request for future use, since after the response is sent back to the client, the request object is never used again. A new one is created for the next request.
