How It Works
Setting Up a Spring-WS Application
To implement a web service using Spring-WS, you first create the following directory structure for your
web application context. Ensure that your lib directory contains the latest version of Spring-WS.
weather/
WEB-INF/
classes/
lib/*jar
temperature.xsd
weather-servlet.xml
web.xml
In web.xml , you have to configure the MessageDispatcherServlet servlet of Spring-WS, which is
different from DispatcherServlet for a typical Spring MVC application. This servlet specializes in
dispatching web service messages to appropriate endpoints and detecting the framework facilities
of Spring-WS.
<web-app version="2.4" 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">
<servlet>
<servlet-name>weather</servlet-name>
<servlet-class>
org.springframework.ws.transport.http.MessageDispatcherServlet
</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>weather</servlet-name>
<url-pattern> /services/*</url-pattern>
</servlet-mapping>
</web-app>
In the Spring MVC configuration file, weather-servlet.xml , you first declare a bean for the weather
service implementation. Later, you will define endpoints and mappings to handle the web service
requests.
<beans xmlns=" http://www.springframework.org/schema/beans"
xmlns:xsi=" http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation=" http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd ">
<bean id="weatherService"
class="com.apress.springenterpriserecipes.weather.WeatherServiceImpl" />
</beans>
