构建carbon组件时出错

Question

我一直在做http://wso2.com/library/tutorials/2014/03/how-to-write-a-wso2-carbon-component/，但是当我使用wsdl文件创建客户端时，我得到了这个错误。我该如何解决这个问题。

这个警告到底是什么意思呢？这是我不能理解的地方..

[java] WARNING: No schemaLocation for import of http://data.mgt.student.carbon.wso2.org/xsd; compilation may fail

看起来目标代码中的../data/xsd目录中的域类尚未更新。我怀疑后端组件已更新，wsdl已更改，但存根尚未更新/创建。因此，客户端组件并不知道这些修改。我建议您可以更新存根资源中的wsdl文件，重新构建存根和客户端可能会解决这个问题。
