[Trustedjava-support] error tpm emulator

[patrizia c. <pat...@in...>]

hi all!

i have a problem: i have done an interation between a client and a =
privacy CA using your example in the JTSS package. The only difference =
is that the client and the PCA are not in the same project, but i've =
realized the PCA as a servlet to simulate a real communication. the =
client and the Pca use the TSS stack. i have create a context in the =
client and in the pca, but when i do the context.connect() in the pca it =
gives me the follow error (i use the tpm emulator):

how can i do? i understand that if the client uses the tpm emulator, the =
PCA doesn't use it. Or not?

Can you suggest me any solution?

thanks patrizia cellesi
