轴 returns 错误 java.lang.NoClassDefFoundError

Question

我有一个基于 axis2 的 Web 服务，它调用另一个 WebService 来获取一些数据。尝试在 axis2 内某处调用另一个服务时（我不能确切地说出位置，因为它在某个 axis2 class 内）发生错误并作为响应返回：

java.lang.NoClassDefFoundError: org/apache/axis2/jaxws/catalog/impl/OASISCatalogManager

所以我想我没有安装某些库或 class。

在我的文件夹 WebService\WebContent\WEB-INF\classes\org\apache\axis2 中，我看到 2 个文件夹：Transport 和 WebApp。

据我所知，class 必须位于 axis2-metadata.jar 内，我已经检查过 - 我的 class 路径中有 "axis2-metadata-1.7.1.jar"。所以我拿了 jaxws/catalog/...etc... 个文件夹，其中包含缺少的 classes（我猜），并将它放在 axis2 文件夹中，就像传输和 webapp 一样，但错误仍然存在。

我的错误调用栈：

我该怎么办？我应该以某种方式配置 axis2 以使用那些 class 文件吗？

请帮忙。

Answer 1

您似乎错过了类路径中的 axis2-metadata.jar。添加它，错误应该消失了。
