问题描述

我是网络服务的新手.我正在尝试调用服务，但出现以下错误.根据我最初的谷歌搜索，这似乎是一个加载器问题，可能是由重复的 jars 引起的，但我无法找到是哪个导致了这个问题.非常感谢任何帮助.

I'm new to webservices. I'm trying to call a service but I'm having the below error. Based on my initial google search seems this is a loader issue that can be caused by duplicate jars, but I cannot locate which one causes this. Any help is very much appreciated.
