[Java] Deploy Spring Web Service

To run a standalone web service, we may see this post. To create a WAR file, we need extra work. Here is the Project Explorer view of EchoService project:

Step-by-step:

1. We copy all Spring framework JAR files and commons-logging JAR file to WebContent/WEB-INF/lib/ directory.
   
2. We copy applicationContext.xml to WebContent/WEB-INF/directory.
3. Provide web.xml in WebContent/WEB-INF/directory.
   

   <?xml version="1.0" encoding="UTF-8"?>
   
   <web-app xmlns="http://java.sun.com/xml/ns/j2ee"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
                           http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
       version="2.4">
       <listener>
           <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
       </listener>
       <servlet>
           <servlet-name>EchoService</servlet-name>
           <servlet-class>com.sun.xml.ws.transport.http.servlet.WSServlet</servlet-class>
       </servlet>
       <servlet-mapping>
           <servlet-name>EchoService</servlet-name>
           <url-pattern>/EchoService</url-pattern>
       </servlet-mapping>
   </web-app>
   

4. Export a WAR file. (May see this post.)
   

Enjoy!
