Re: [Trustedjava-support] NullPointerException in TcIRsaKey.certifiyKey()

[Ronald T. <ron...@ia...>]

Hi,

Hmmm, the line that throws the Exception
is as simple as
long resultCode = ((Long) outDataTpm[0]).longValue();
and there should always be some return value..
Also, the HW TPMs should be fine. Perhaps there are different software 
setups on the two machines?

Please try LocalTCSBindings and do some more detailed debugging / 
perhaps stepping through the code to narrow the problem down.

Ronald
