How do you display the image in your database? I mean, I want to display the image i stored in my database to my jsp.

This code is perfectly working , I could store an image into database using this program but i am unable to retrieve the page. The image is getting decoded but when i am trying to send the content to a file and open it, it is giving me the name fo the file but the picture is not getting opened. So any one can help me.
Thanks advans

Yes, at http://examples.codecharge.com/CCSExamplePack2/FileUpload/FileUpload.php
You can create it with CodeCharge Studio, of course.

i think this only inserted nothing but a string into image, so you can never open it... and the string is something like "java.io.FileInputStream@121cc40".

Dear Sir,
I tried your code. But I'm not sure to which directory does it save the file.
This directory should be on the server. Isn't it?
I tried adding a path but I still can't find the file. Can you help?
I'm really new to JAVA programming.
Regards,

I was really happy when i found this topic, because I thought it could save all my problems, but I have the next problem on my server when I execute your code:
java.lang.IndexOutOfBoundsException: The supplied offset + length did not fit into the supplied byte[] (offset + length = 7619 + 21580 = 29199 vs byte[].length = 21580)
Do you have any solutions to this???
Thank you very much...
