嘗試在wso2 greg中列出wsdls時發生異常

當我在WSO2 Governance Registry的管理控制檯中單擊Main/Metadata/List/WSDL時，顯示空白屏幕。嘗試在wso2 greg中列出wsdls時發生異常
有關我如何開始故障排除的任何想法？
它可能已經開始與我導入一些WSDL文件有關，但我不確定。

基礎上例外，我認爲這是在WSDL文件中有語法錯誤...希望有這是不正確寫入標籤.. ;在序言意外字符 '['（代碼91）：com.ctc.wstx.exc.WstxUnexpectedCharException -
ERROR {org.apache.axis2.rpc.receivers.RPCMessageReceiver}預計 '<'
感謝，

謝謝，但它實際上既不是一個wsdl也不是一個xsd有這個字符，但另一個資源，與wsdl zip一起偶然導入。 – nize 2013-04-26 13:01:53
我找到了原因。這是我偶然在我導入的wsdl zip文件中包含兩個隱藏文件：deskop.ini和vssver2.scc。那些字符[使wso2 greg去香蕉。
皮尤，我想我應該報告這是一個錯誤。 WSO2 GREG中的WSDL zip文件處理程序不應接受這些文件！

嘗試在wso2 greg中列出wsdls時發生異常
