on the other node that I try to get the DID of. I have already put jna-4.5.1.jar file to jre/lib and each node's djvm folders. But still I'm getting the CNF exception. Can anyone help on this?

Steps to reproduce

  1. Copied cordentity-cordapp-0.5.0 to PartyA and PartyB cordapp dirs
  2. Start indy-pool and created indy.properties files for each node
  3. Start the flow on a PartyB using flow start com.luxoft.blockchainlab.corda.hyperledger.indy.flow.b2b.GetDidFlowB2B$Initiator authority: "O=PartyA,L=London,C=GB"
