Code Listing 2: Using OrdHttpUploadFormData to upload an HTML form

// Create an OrdHttpUploadFormData object and use it to parse the
// multipart/form-data message.
//
OrdHttpUploadFormData formData = new OrdHttpUploadFormData( request );

formData.parseFormData( );

// Get the description, location, and photograph.
//
String id = formData.getParameter("id");

String description = formData.getParameter("description");
String location = formData.getParameter("location");
OrdHttpUploadFile photo = formData.getFileParameter("photo");

// Prepare and execute a SQL statement to insert a new row into
// the table and return the sequence number for the new row.

// Disable auto-commit to allow the LOB to be written correctly.
//
conn.setAutoCommit(false);
PreparedStatement stmt = conn.prepareStatement("insert into photo_album (id, 
     description, location, photo) " + " values (?, ?, ?, ORDSYS.ORDIMAGE.INIT( ))");
stmt.setString(1, id);
stmt.setString(2, description);

stmt.setString(3, location);
stmt.executeUpdate( );

// Prepare and execute a SQL statement to fetch the new OrdImage
// object from the database.
//
stmt = conn.prepareStatement("select photo from photo_album where id = ? for 
     update");

// Load the photograph into the database and set the properties.

//

// Prepare and execute a SQL statement to update the image object.
//
