Creating Web services using Apache CXF (Part 3): Configurations

  • Web.xml Declarations

We have to declare Spring Context Listener, CXF Servlet, Spring Context Location and URL Mapping.

   1: <?xml version="1.0" encoding="UTF-8"?>
   2: <web-app id="services" version="2.5"
   3:     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee"

   7:     
   8:     <!-- Adding the Spring Context Listener. It will help to init Spring Context -->
   9:     <listener>
  10:         <listener-class> org.springframework.web.context.ContextLoaderListener 
  11:         </listener-class>
  12:     </listener>
  13:     
  14:     <!-- Context file location of Spring -->
  15:     <context-param>
  16:         <param-name>contextConfigLocation</param-name>
  17:         <param-value>/WEB-INF/applicationContext.xml</param-value>
  18:     </context-param>
  19:     
  20:     <!-- CXF Servlet -->
  21:     <servlet>
  22:         <servlet-name>CXFServlet</servlet-name>
  23:         <servlet-class> org.apache.cxf.transport.servlet.CXFServlet 
  24:         </servlet-class>
  25:     </servlet>
  26:     
  27:     <!-- Mapping with a URL Pattern -->
  28:     <servlet-mapping>
  29:         <servlet-name>CXFServlet</servlet-name>
  30:         <url-pattern>/*</url-pattern>
  31:     </servlet-mapping>
  32: </web-app>

Create a WAR out of this Project and deploy it in Apache Tomcat. And try to access the WSDL URL

 http://localhost:8080/CXFExample/ProductService?wsdl.
