Welcome,
HThalesAdaptor is a java library for use with JPOS to connect to Thales RG7000 and RG 8000 HSMs
It expands JPOS FSDMsg functionality to process Thales Racal command set, and have a Q2/JPOS-EE compatible component, much like JPOS Q2 Channel Adaptor to maintain the connection with the HSM.
You can use it without JPOS, just make sure the jpos library is available in your classpath
It should be PCI compliant.
