场景：

  1. 我正在Linux实例上运行irs-demo应用程序
  2. NodeExplorer已安装在Windows实例上

  3. 我尝试连接到irs-demo的BankA节点，以使用NodeExplorer的帮助查看节点库和事务 以下命令：

    java -jar corda-tools-explorer-3.2-corda.jar

  4. 以下是我用来登录NodeExplorer的PartyA凭据

      Corda Node: <IP_address_of_Linux_instance>
  Port: <RPC_port_number>
  Username: <RPC_user>
  Password: <RPC_password>

观察：

  1. 当PartyA不执行任何交易时，我可以使用大约凭据成功登录到NodeExplorer并连接到PartyA

  2. 当我使用Web浏览器为PartyA进行少量交易，然后尝试使用相同的凭据登录到NodeExplorer时，抛出以下异常：

注意：
如果我在单个Windows实例上运行irs-demo应用程序和NodeExplorer，则会遇到相同的例外情况

2 个答案:

答案 0 :(得分：0)

主要例外是：

Caused by: java.lang.ClassNotFoundException: net.corda.irs.contract.InterestRateSwap$State

这表明节点浏览器未安装IRS CorDapp，因此无法反序列化InterestRateSwap$State对象。

这似乎是一个错误。我在这里提出了它：https://r3-cev.atlassian.net/browse/CORDA-1992。

答案 1 :(得分：0)

这是您需要手动将小姐类文件放入Node Explore中的临时方法，之后您将发现事务流进入Explorer。
