Попробуйте использовать «grpcs: //» в своих URL-адресах - channel.addOrderer (client.newOrderer ("orderer.example.com", "grpcs: //192.168.99.100: 7050", ordererProperties)); channel.addPeer (client.newPeer ("peer0.org1.example.com", "grpcs: //192.168.99.100: 7051", peerProperties));
лал следующее в соответствии с предложением, которое я получил от моегопредыдущий пост для связи с локально работающей сетью Hyperledger Fabric V1.0 из Java-приложения. Но я получаю исключения, приведенные ниже, и не могу разобраться, почему это происходит.

И, запустив код в Java-проекте eclipse, получаю следующее исключение.

Кто-то, пожалуйста, посмотрите в коде, помогите мне найти, где я делаю неправильно.
