Creation of JPG file

Question

Hi,
I have a jsp page that display's data from the database in html table format.Now i have a button called "image" at the bottom.I want that when the user clicks on the image button a jpg file should be reandered to the user that would contain the table data (from the database) that is displayed in the jsp.
I am fairly new to image creation in java.I know that i need to use the
response.setContentType("image/jpeg"); to render the jpg back to the user but don't know how to write the data that is displayed in the table in the jsp to this jpg file and generate this file and show back to the user.
I also know that i need to use a byte [] but dont know how to do this.
Is there any way to achieve this?Thanks in advance.
Regards,
Aditya
