Image corruption

I do not have much experience in image manipulation. I am trying to take an upload from webapp place into the database and retrieve with a servlet (which dynamically resizes the image). Everything works except sometimes the image, which are all jpg, turn grey halfway through the drawing process. Since this occurs no matter how the image is dynamically sized, I can only assume that it is being stored in the db that way during the upload. Could someone browse through my code and see if there is anything that would cause this?

BTW, getInputStream() is called on a struts FormFile, so that shouldn't be the problem.

ImageIO.read() returns a BufferedImage, so there's no need to "convert".
I don't see anything else obvious here. You should try writing the image out to a file before resizing it. Then you can see if your problem is on the input or output side.

BTW, I solved the problem!

The column that I am storing it in was a BLOB, which only holds 16KB. I changed to MEDIUMBLOB with holds 16MB. Thanks for the help.
I agree. Here's the link: http://aspose.com/file-tools
