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.我正在尝试实施的教程是http://codeoncloud.blogspot.gr/2012/12/create-java-web-service-in-eclipse_3982.html

Answer 1

我有同样的问题,并通过复制成功地解决了它xmlschema-core-*.jar的形式axis2-*/lib/来my_project_root_directory/WebContent/WEB-INF/lib/.

Answer 2

我也尝试创建一个简单的 Web 服务（配置为：Dynamic Web Module 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]：

“[警告] 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：我根据需要更新 web.xml 解决了这个问题。

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

由于某种原因，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) 未导入到 WebContent/WEB-INF/lib 中。

解决方案：所以我必须将其粘贴到那里。

之后，jstl 的其他问题：

• 当我尝试以管理员身份登录 WebService 时出现此问题

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： http://java。 sun.com/jsp/jstl/core无法在 web.xml 或使用此应用程序部署的 jar 文件中解析 (...)

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

所以我也必须将它们粘贴到 WebContent/WEB-INF/lib 中。

这就是大家。我希望它有帮助。
