Hello, thanks for the information.
For me it's really unclear and the documentation provided is very misleading.
My problem is that I need to sign XML documents with XaDES. So far we recieved our certificates as files - co we created a small Java app that was able to do the work (background job that was runing app and signing XMLs) . Nowadays policy has changed and we need to use security tokens / smart cards.
I found information about SSF and I thought it has all I need - smartcards and envelopes - but you say it's not working 
Do you know any 3rd party product that we could use for this purpose?
Best regards
Ana
