Integration of GP in a tool to calculate derived keys and install cap file

[Etantonio2016]

Hi,
I'd like to create a Java tool that communicates with the smart card reader and using GlobalPlatformPro sends something similar to gp -v -i -d the scope is to obtain the following highlighted fields , I need them to determine the keys derived from the master key

Later I would want also to install my applet on the smart card using SCP03 Mutual Autentication

What should I do to achieve this?
I think 2 solutions are available:

1. Call gp.exe from java like a command line application , parse the results and call again gp.exe to install the cap file

2. Do something similar to what is present in GPTool.java so make it all in java without call gp.exe as external application

Can you suggest me the recommended approach?

Thanks,
Antonio
