在我尝试获取 DID 的另一个节点上。我已经把jna-4.5.1.jar文件jre/lib和每个节点的djvm文件夹。但我仍然收到 CNF 异常。有人可以帮忙吗？

重现步骤

  1. 复制cordentity-cordapp-0.5.0到 PartyA 和 PartyB cordapp 目录
  2. 启动 indy-pool 并为每个节点创建 indy.properties 文件
  3. 使用在 PartyB 上启动流程flow start com.luxoft.blockchainlab.corda.hyperledger.indy.flow.b2b.GetDidFlowB2B$Initiator authority: "O=PartyA,L=London,C=GB"
