EJB, Spring Remoting, and Web Services - Spring Enterprise Recipes: A Problem Solution Approach - page 224

Solution
Spring comes with several service exporters that can export a bean as a remote service based on the
RMI, Hessian, Burlap, or HTTP Invoker remoting technologies, but Spring doesn't come with a service
exporter that can export a bean as a web service. However, there's an external framework called XFire
( http://xfire.codehaus.org/ ) th at supplies one. XFire is an open source Java SOAP framework that can
export a simple Java object as a web service. XFire supports Spring by providing facilities such as a
service exporter and a client proxy factory bean, whose usage is consistent with those provided by Spring
for other remoting technologies.

How It Works

Exposing a Web Service Using XFire
To expose a web service using XFire in Spring, you first create the following directory structure for your
web application context.

■ Note To expose a web service using XFire, you have to download and install XFire (e.g., v1.2.6). Then copy

xfire-all-1.2.6.jar (located in the root of the XFire installation), activation-1.1.jar , jdom-1.0.jar ,
stax-api-1.0.1.jar , wsdl4j-1.6.1.jar , and wstx-asl-3.2.0.jar (all located in the lib directory) to the
WEB-INF/lib directory.

lib/*jar
weather-servlet.xml
web.xml

In web.xml , you configure Spring MVC's DispatcherServlet and map all the URLs under the
services path to it.
