Question

当我尝试从客户端建立RPC连接时，Node日志上出现以下异常。client.start（）方法似乎被卡住了。代码如下。我正在Jetty托管的servlet中运行此代码。

        final NetworkHostAndPort nodeAddress = NetworkHostAndPort.parse("localhost:10008");
        final CordaRPCClient client = new CordaRPCClient(nodeAddress, CordaRPCClientConfiguration.DEFAULT);
        // Can be amended in the com.example.Main file.
        CordaRPCConnection clientConn= client.start("user1","password");

        rpcOps =clientConn.getProxy();

        rpcOps.waitUntilNetworkReady();

以下是我在节点日志中看到的异常。

我在测试中遇到了类似的问题，结果发现我的客户端库与服务器版本不同。错误日志显示服务器具有3.2。您在客户端上使用的RPC是什么版本？
