  1. i follow your source code, but i have error in row 93(in your Sourcode):
    or in this sourcode =>  image = getToolkit().createImage(imageBytes);
    error on getToolkit().createImage(imageBytes)..
    what declaration of getToolkit() and createImage(imageBytes)?
    or what should i import in lib for this code?
    please respons, and sorry for my english

  7. i have error in this line : img=getToolkit().createImage(imageBytes);
    Error:variable imageBytes might not have been initialised.. so i initialized as: byte[] imageBytes = null;
    now the runtime Error :
    java.sql.SQLException: Parameter index out of range (1 > number of parameters, which is 0). How to solve this
