无法部署 IBM Bluemix 提供的 java 链代码

Question

来自 restclient 的请求：

发布http://localhost:7050/chaincode

请求：
{ "jsonrpc": "2.0", “方法”：“部署”， “参数”：{ “类型”：1， “链码ID”：{ “名称”：“拉贾” }, “ctorMsg”：{ "args":["init", "a", "100", "b", "200"] } }, “身份证”：5 }

用链码id名称注册java链码：

rajasekhar@rajasekhar-VirtualBox:~/mychaincode/src/github.com/hyperledger/fabric/examples/chaincode/java/chaincode_example02/build/distributions/chaincode_example02/bin$ CORE_CHAINCODE_ID_NAME=raja  ./chaincode_example02

您需要提供更多信息，说明您目前所做的工作。仅使用错误消息 - 无法确定失败的原因。

这里有关于如何为区块链编写 Java 链代码的优秀文档：https://www.ibm.com/developerworks/library/j-chaincode-for-java-developers/index.html

我希望您已经看过上述文档。请一一完成这些步骤。该文档在设置环境以使用 Java 编写您的第一个链代码方面非常广泛。

希望这会有所帮助。
