java - 为什么我不能部署包含一些外部 jar 文件的 java webservice ..？

Question

我正在使用 axis2 部署 java Web 服务。

我已经创建了 Web 服务演示，我的 Java Web 服务中没有包含外部 jar，而且效果很好。但是当我尝试使用一些外部库创建 Java 的 Web 服务时，同样的事情不起作用。为什么会这样？

在部署该 Web 服务时出现此异常

我认为在创建 .aar 文件时我需要进行一些更改？如果是，那么更改应该是什么？

在下图中，我包含了三个库作为外部库sphinx4.jarjsapi.jarwsj...jar

Answer 1

我已经通过在项目中添加 lib 文件夹并在构建路径中包含 jar 解决了这个问题。

只需将所有你想要的jar复制到lib文件夹中，然后右键单击jar ->go to build path->add to build path

只有这样，你才会成功。
