jTSS is a standalone TSS, it can communicate directly with the
/dev/tpm in Linux and to the Trusted Base Services (TBS) in Vista.

TrouSerS is a standalone C TSS. In Linux TrouSerS talks directly to
the /dev/tpm.

Only one TSS can access the TPM device, thus you cannot run both TSS'
at the same time.


However, if you want to do both C and Java TPM development you can use
the jTSSWrapper package which maps the jTSS high-level API to the
TrouSerS C API via Java JNI magic.

So you can run jTpmTools with standalone jTSS as well as jTSS via
jTSSWrapper on top of TrouSerS. Note, however, that jTSS and TrouSerS
do not implement the same set of TSS commands. Some commands may only
work on jTSS, some only on TrouSerS.

It's available from http://jce.iaik.tugraz.at/
You need to register to download the free demo versions.
