以下条目被写入wso2carbon.log：

我找到了原因。是我不小心在我导入的wsdl zip文件中包含了两个隐藏文件：deskop.ini和vssver2.scc。那些具有[使 wso2 greg 变得疯狂的性格。

皮尤，我想我应该将此报告为错误。WSO2 GREG 中的 WSDL zip 文件处理程序不应接受此类文件！

基于异常，我认为 wsdl 文件中存在语法错误...希望有一个未正确编写的标签...

错误 {org.apache.axis2.rpc.receivers.RPCMessageReceiver} - com.ctc.wstx.exc.WstxUnexpectedCharException：序言中出现意外字符“[”（代码 91）；预期'<'

谢谢，
