ERROR receivers.RPCInOnlyMessageReceiver：尝试调用服务方法placeOrder时发生异常

时间：2015-07-25 11:05:20

标签： wso2esb wso2is wso2carbon

我是＆＃34; WSO2 ESB＆＃34;的新手平台。我正在尝试从https://docs.wso2.com/display/ESB481/Sample+800%3A+Introduction+to+REST+API运行WSO2 ESB Rest API示例，所以我按照所有步骤进行操作

1）在一个终端上，我执行

C:\wso2esb-4.8.1\samples\axis2Server>axis2server.bat

2）在另一个终端上

C:\wso2esb-4.8.1\bin>wso2esb-samples.bat -sn 800

当我运行以下Rest URL时，它给了我错误。请帮助我知道为什么最后一个CURL命令没有提供所需的输出？

Edit-1 ：我在/wso2esb-4.8.1目录下创建了placeorder.xml文件。

C:\WSO2-ESB\wso2esb-4.8.1>curl -v -d @placeorder.xml -H "Content-type: application/xml

从链接中，似乎＆＃34; ESB将202响应返回给客户端＆＃34; 。这是对的吗？

1 个答案:

答案 0 :(得分：1)

  

ERROR receivers.RPCInOnlyMessageReceiver：发生异常时   试图调用服务方法placeOrder   java.lang.IllegalArgumentException：参数数量错误

在终端中运行以下命令时会发生上述错误。

  

curl -v -d @ placeorder.xml -H“Content-type：application / xml”   http://127.0.0.1:8280/stockquote/order/

您必须从您拥有placeorder.xml文件的目录运行上面的curl命令。你在同一目录中有placeorder.xml文件吗？如果没有，则必须从您具有placeorder.xml的目录运行命令，或者在运行上述curl命令时必须提供placeorder.xml文件的路径。

修改-1 您应该使用以下内容创建placeorder.xml文件并将其保存在您的计算机中。 

<placeOrder xmlns="http://services.samples">
  <order>
     <price>50</price>
     <quantity>10</quantity>
     <symbol>IBM</symbol>
  </order>
</placeOrder>
