Problem in uploading image greater than 500KB

Question

This is a servlet method which is being called by the doGet() or doPost() method. I have developed this code to store an image in sql server 2005. This code is working very fine with image size < 500 KB but when i try to upload a file of even 501 KB it gives me error listed below. What exactly is the problem and how can i overcome it?
protected void processRequest(HttpServletRequest request, HttpServletResponse response)             throws ServletException, IOException {         response.setContentType("text/html;charset=UTF-8");         PrintWriter out = response.getWriter();         Part p = request.getPart("file");                      //part of servlet API 3.0         out.println(p.getSize());//part of servlet API 3.0         InputStream in = (InputStream) p.getInputStream();//part of servlet API 3.0       //  byte[] b = new byte[(int)p.getSize()];//part of servlet API 3.0       //  in.read(b, 0, b.length);         Connection connection = null;         PreparedStatement stmt = null;         HttpSession session = request.getSession();         String username = (String) session.getAttribute("username"); //part of servlet         try {             Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");             Properties properties = new Properties();             connection = DriverManager.getConnection("jdbc:odbc:sn", properties);             stmt = connection.prepareStatement("UPDATE Photos SET Photo = ? WHERE username = ?");             stmt.setBinaryStream(1, in,in.available());             stmt.setString(2, username);             int rows = stmt.executeUpdate();             if (rows > 0) {                 RequestDispatcher view = request.getRequestDispatcher("Home.jsp");                 view.forward(request, response);             }         } catch (ClassNotFoundException ex) {             out.println(ex);         } catch (SQLException ex) {             out.println(ex);         } finally {             in.close();             try {                 connection.close();                 stmt.close();             } catch (SQLException ex) {                 ex.printStackTrace();             }             out.close();         }     }
The error message which i am receiving while uploading the image < 500 KB is
java.sql.SQLException: [Microsoft][ODBC SQL Server Driver][SQL Server]The text, ntext, or image pointer value conflicts with the column name specified.
Please help me thanks in advance.
