Answer 1

Download Java Card documentation and look into Java Card Virtual Machine specification. It explains every detail of CAP file format and is (to the best of my knowledge) completely correct and contains just one minor error which is not relevant to you.

Answer 2

I tried following approach and succeed:

• Extract .cap file with any zip extractor (for eg WinZip)

• After extraction you will get a MF file (normally named as MANIFEST.MF)

• This file contains all information you are asking for
