有人可以帮忙吗？网上查了一下，发现apache tomcat lib目录下有一个文件httpcore-xx.jar必须要放。我试过了，但没有用。我正在使用 ubuntu 14.04 LTS 和 eclipse。我还尝试清理我的项目并重新构建。它没有用。我面临的是该页面正在 Web 浏览器上加载，但是当我单击服务时，出现了之前的错误。我正在尝试实现的教程是 http://codeoncloud.blogspot.gr/2012/12/create-java-web-service-in-eclipse_3982.html

我遇到了同样的问题并通过复制 xmlschema-core-*.jar 成功解决了它表格 axis2-*/lib/至 my_project_root_directory/WebContent/WEB-INF/lib/ .
