有人可以帮忙吗？我在互联网上搜索，发现有一个文件httpcore-xx.jar必须放在apache tomcat lib目录中。我试过了，但它没有用。我使用的是ubuntu 14.04 LTS和eclipse。我还尝试清理我的项目并再次构建。它没有用。我面临的是页面正在加载到Web浏览器上，但是当我点击服务时，会出现上一个错误。我试图实施的教程是http://codeoncloud.blogspot.gr/2012/12/create-java-web-service-in-eclipse_3982.html

Answer 1

我遇到了同样的问题，并通过将xmlschema-core-*.jar表单axis2-*/lib/复制到my_project_root_directory/WebContent/WEB-INF/lib/成功解决了问题。

Answer 2

我也试图创建一个简单的Web服务（配置为：动态Web模块2.5），使用： - Tomcat 8.0和 - Axis2 1.7.4（axis2-1.7.4-war）。

我收到以下错误：

[WARN] Web application uses org.apache.axis2.transport.http.AxisAdminServlet; please update web.xml to use org.apache.axis2.webapp.AxisAdminServlet instead
[INFO] Clustering has been disabled
[WARN] Unable to instantiate deployer org.apache.axis2.deployment.ServiceDeployer; see debug logs for more details

第一个问题是[警告]：

＆＃34; [WARN] Web应用程序使用org.apache.axis2.transport.http.AxisAdminServlet; 请更新web.xml以使用org.apache.axis2.webapp.AxisAdminServlet而不是＆＃34;

解决方案：我解决了根据需要更新web.xml的问题。

第二个问题是：

java.lang.NoClassDefFoundError：org / apache / ws / commons / schema / resolver / URIResolver
引起：java.lang.ClassNotFoundException：org.apache.ws.commons.schema.resolver.URIResolver

出于某种原因，当我创建一个配置了Axis2的新动态Web项目时， xmlschema-core-2.2.1.jar（axis2 / WEB-INF / lib）未导入WebContent / WEB-INF / lib。

解决方案：所以我不得不把它贴在那里。

之后，jstl的其他问题：

当我尝试在WebService上以管理员身份登录时，出现了此问题

abr 13,2017 9:54:30 PM org.apache.catalina.core.ApplicationDispatcher 调用GRAVE：servlet jsp的Servlet.service（）抛出异常 org.apache.jasper.JasperException：绝对的uri：无法在web.xml中解析http://java.sun.com/jsp/jstl/core 或者使用此应用程序部署的jar文件（...）

解决方案：

我下载了这些罐子： - taglibs-standard-impl-1.2.5.jar和 - taglibs-standard-spec-1.2.5.jar

来自tomcat.apache.org/download-taglibs.cgi

所以我不得不将它们粘贴在WebContent / WEB-INF / lib中。

所有人。我希望它有所帮助。

Answer 3

IT也为我工作。 axis2-1.7和axis2-1.6都适用于我，只是将xml-core复制到web / lib文件夹并构建路径并且工作正常。

Answer 4

这对我有用：

https://yiingw.wordpress.com/2018/02/12/axis2-java-lang-noclassdeffounderror-org-apache-ws-commons-schema-utils-namespaceprefixlist/

原因：：Axis2 1.7.x使用的XmlSchema 2.2.x与   Axis2 1.6.x和Eclipse不会将新版本的XmlSchema复制到   Web应用程序。

解决方案：从$ AXIS2_HOME / lib手动复制xmlschema-core-2.2.1.jar   到Eclipse项目目录WebContent / WEB-INF / lib，关闭并   生成Web服务客户端之前，请重新打开Eclipse。

java.lang.NoClassDefFoundError：org / apache / ws / commons / schema / resolver / URIResolver
