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。我尝试过，但它没有用。我正在使用ubuntu 14.04 LTS和eclipse。我还尝试清理我的项目并再次构建。它没用。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。我试图实现的教程是http://codeoncloud.blogspot.gr/2012/12/create-java-web-service-in-eclipse_3982.html

我有同样的问题，并通过将qazxsw poi从qazxsw poi复制到qazxsw poi成功解决了它。

我正在尝试创建一个简单的Web服务（配置：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：

xmlschema-core-*.jar

第一个问题是[WARN]：

“[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”

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，当我创建一个使用Axis2配置的新动态Web项目时，xmlschema-core-2.2.1.jar（axis2 / WEB-INF / lib）未导入到WebContent / WEB-INF / lib。

解决方案：所以我必须将其粘贴到那里。

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uri：axis2-*/lib/无法解析web.xml或使用此应用程序部署的jar文件（...）

解：

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my_project_root_directory/WebContent/WEB-INF/lib/

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

这就是所有人。我希望它有所帮助。

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它工作正常。

这对我有用：

[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 abr 13, 2017 9:03:35 PM org.apache.catalina.core.ApplicationContext log GRAVE: StandardWrapper.Throwable java.lang.NoClassDefFoundError: org/apache/ws/commons/schema/resolver/URIResolver at org.apache.axis2.deployment.ModuleDeployer.deploy(ModuleDeployer.java:128) (...) Caused by: java.lang.ClassNotFoundException: org.apache.ws.commons.schema.resolver.URIResolver at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1332) ... 24 more abr 13, 2017 9:03:35 PM org.apache.catalina.core.StandardContext loadOnStartup GRAVE: Servlet [AxisAdminServlet] in web application [/AxisTestWebServer] threw load() exception java.lang.ClassNotFoundException: org.apache.ws.commons.schema.resolver.URIResolver at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1332) (...)

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

解决方案：手动将xmlschema-core-2.2.1.jar从$ AXIS2_HOME / lib复制到Eclipse项目目录WebContent / WEB-INF / lib，关闭并重新打开eclipse，然后再生成Web服务客户端。
