Is the actual content of this byte[] the same as the image file? I.e.:
- was the file read fully?
- saving this byte[] back to a FileOutputStream with different name gives a correct image?
- use this byte in your next code (the one to display the image from the blob) and see if it works
Another option would be to convert the initial byte[] (from the inputstream) to a non-binary array (base64 or hexa values) and save it to the blog. Then when reading it back, converting to the original format. But this solution needs processing time and takes more space in the DB.
