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部署一个java Web服务。

我已经创建了 web 服务的演示，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..为什么会发生这种情况？

在部署该 Web 服务时，我遇到了这个异常

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，我包含三个库作为外部库 sphinx4.jar jsapi.jar wsj...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。

只需将你想要的所有jar复制到lib文件夹中，然后右键单击jar ->转到构建路径->添加到构建路径

只要这样，你就会成功。

感谢 Bhavik Kama 的回答。我遇到了同样的问题，从博客中得到了 ides，我的回答是 jar 文件应该复制到文件夹 webserviceproject\webcontent\web-inf\lib 中。
