generate a dynamic table on JSP page

Hi Experts,
           I am displaying the attached chart on my jsp page, Every new month is added in the X-axis as soon as the month gets populated in the Database Table.
           What I want to achieve is , Display the data (SLA Compliance column of the table) present in the chart in a tabular Form, with Column names as months, and with the addition of a new month, a new column should automatically be generated.
           Can someone please help me out with this.

           I have attached the Chart snap shot along with  a snippet of backend Table, used for this chart

1.  First create a bean with Application, Month, Year, SLA_COMPLIANCE and then Total_Metrics attributes and for example we will call it BeanA.

2.  Next in the servlet create a ArrayList named BeanA_ArrayList.

3.  Next loop thru database resultset and as you read each row from the result set, create a new BeanA.

4.  Once done creating BeanA from step3, then add it to a ArrayList called BeanA_ArrayList.

5.  Then store the ArrayList to the request object.

5.  Once done call your jsp page you want to display your table in.

6.  Next in your jsp add addressibility to the ArrayList from the request object.

7.  Next loop thru the arraylist and build the html on the fly.

Look at the below tutorial then go to booklist.jsp... will show you...

Heres their example, notice that arraylist books is retrieved from the request object.  The servlet prior to calling the jsp, set the attribute of books with the ArrayList they wanted.

<%                                    ArrayList arrayList = (ArrayList)request.getAttribute("books");                            //loope über die Liste von Büchern und gibt die Eigenschaften aus              for (Iterator iter = arrayList.iterator(); iter.hasNext();) {                    Book element = (Book) iter.next();                                      out.println("<tr>");                  out.println("<td>" + element.getAuthor() + "</td>");                  out.println("<td>" + element.getTitle() + "</td>");                  if(element.isAvailable())                        out.println("<td><input type="checkbox" name="available" value="true" disabled checked></td>");                  else                        out.println("<td><input type="checkbox" name="available" value="true" disabled></td>");                                    out.println("<td><a href="bookEdit?do=edit&id=" + element.getId() + "">Edit</a></td>");                  out.println("<td><a href="bookEdit?do=delete&id=" + element.getId() + "">Delete</a></td>");                  out.println("</tr>");              }        %>
