While performing AES encryption using SunJCE provider, I did not see usuage of the mode in the program provided. I have few questions: Do we really need to specify the mode when using AES? Does PaddingException happen with AES and how do we prevent the PaddingException?

Please let me know.

AES mode on this page is insecure

The example for AES did not specify a mode which results in the default of ECB mode in most JCE providers!! I fixed that line and commented, but this will need some other work as it is not providing any Initialization Vector (IV) to the AES encryption since it was using ECB mode originally (bad). Will try to fix this with a working example.
