Re: [Trustedjava-support] error in jTPM running!

This is described in the jTSS documentation (did you read it?):

"The non-volatile memory of the TPM emulator holding permanent state
information is located in:

/var/tpm/"

What you have to do is to remove the TPM emu storage file in /var/tpm 
and start the emu with the "clear" option.

The error message actually is very verbose. The libtspi.so.1 library can 
not be found by the linker. Check where TrouSerS installed this library 
(likely /usr/local/lib) and add this path to you linker search path 
(e.g. by modifying your /etc/ld.so.conf or by adding it to your 
LD_LIBRARY_PATH).

Reset the emulator as described above. Question about the IBM tools 
should be asked on IBM mailing lists.
