運行Web服務時Axis2錯誤

Question

我是Java Web服務的新手。 我准備了一個.aar文件，並使用axis2將其部署在tomcat5.5.35中。

現在，在運行Web服務時，我發現了一個奇怪的錯誤

org.apache.axis2.dataretrieval.DataRetrievalException: Failed to load from file, META-INF/ServiceData.xml

我不知道背后的原因。 我的.aar文件包含列出服務的services.xml。 但是，為什么Axis嘗試加載該ServiceData.xml文件。 我正在使用axis2的jdk1.6和tomcat5.5。

完整的錯誤日志如下

如果有人可以幫助我解決這個問題，那就太好了。

Axis2檢查服務元數據文件“ avax.xml.stream.XMLStreamException：服務存儲庫中不存在該文件！File = META-INF / ServiceData.xml”。您的服務.aar文件夾結構正確嗎？

在您的* .AAr文件中，您應該具有META_INF文件和您的實現。
