运行Web服务时Axis2错误

Question

我是Java Web服务的新手。我准备了一个.aar文件，并使用axis2将其部署在tomcat5.5.35中。

现在，在运行Web服务时，我发现了一个奇怪的错误

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文件包含列出服务的services.xml。但是，为什么Axis尝试加载该ServiceData.xml文件。我正在使用axis2的jdk1.6和tomcat5.5。

完整的错误日志如下

如果有人可以帮助我解决这个问题，那就太好了。

Axis2检查服务元数据文件“ avax.xml.stream.XMLStreamException：服务存储库中不存在该文件！File = META-
INF / ServiceData.xml”。您的服务.aar文件夹结构正确吗？

在您的* .AAr文件中，您应该具有META_INF文件和您的实现。

test.aar|-----META_INF
