Question

我现在在Eclipse中使用Web服务一直在努力。每当我得到一些工作，它似乎只是基于运气，我已经以多种方式尝试了一切。

我的最新问题涉及以下方面：我有一个使用大量外部引用（jar）的java应用程序。我已经使用Fat-jar插件（http://fjep.sourceforge.net/）将这个java项目导出到一个简单的jar文件中，以确保导出的jar包含所有需要的资源。然后，我创建了一个动态Web项目，并将之前的jar添加到此项目中。当我做一些基本测试时，一切正常，即Eclipse找到所有需要的引用。

但是，当我尝试创建一个Web服务时，其方法使用与测试完全相同的逻辑，我得到错误。我不明白为什么我得到一个ClassNotFoundException，因为就像我之前说过的那样，在进行本地测试时，Eclipse会找到所有需要的资源。

如果有人有想法，我会非常感激。

谢谢，托马斯

Answer 1

实际上，您正面临NoClassDefFoundError，当在运行时找不到所需的lib时会发生这种情况...检查libs是否在您的运行时类路径中。

Answer 2

你的意思是在eclipse环境中你的web服务工作正常，但在你的动态web项目中不起作用？你的动态网络项目中缺少jar？

Answer 3

确保至少这些激活1.1.jar，公理-API-1.2.8.jar，公理-DOM-1.2.8.jar，公理IMPL-1.2.8.jar， Axis2的-ADB-1.5.1.jar， Axis2的内核-1.5.1.jar， Axis2的运输-HTTP-1.5.1.jar， Axis2的运输和本地1.5.1.jar，公地编解码器1.3.jar，公地文件上传-1.2.jar，公地httpclient的-3.1.jar，共享记录-1.1.1.jar， Geronimo的StAX的api_1.0_spec-1.0.1.jar，的HttpCore-4.0.jar，邮件1.4.jar， neethi-2.0.4.jar，沃登-API 1.0M8.jar，沃登-IMPL-DOM-1.0M8.jar， WSDL4J-1.6.2.jar， wstx-ASL-3.2.4.jar， XMLSchema的1.4.3.jar

Answer 4

我也遇到了这个问题。就我而言，我没有在[1]文章中清楚地遵循这些步骤。在步骤12中，不要更改“服务项目”名称。

使用Axis2的Eclipse中的Web服务：ClassNotFoundException
