This example demonstrates the following aspects of the Web Services (WS) support available with Spring Integration:

1. WS Outbound Gateway
2. Content Enricher
3. Composed Message Processor

A very simple example that show you how easy it is to invoke a service based on the [Simple Object Access Protocol][] (SOAP) using Spring Integration.

• A Message is sent to a Channel, where it is retrieved by a Chain which consists of a Header Enricher and a WS Outbound Gateway.
• The Header Enricher enriches the Message with the SOAP action header.
• The WS Outbound Gateway converts the Message to a SOAP request and sends it to a remote service, which converts a temperature from Fahrenheit (90F) to Celsius (32.2C) and the result is printed to the console:

<?xml version="1.0" encoding="UTF-8"?><FahrenheitToCelsiusResponse xmlns="http://tempuri.org/"><FahrenheitToCelsiusResult>32.2222222222222</FahrenheitToCelsiusResult></FahrenheitToCelsiusResponse>````

## Running the Sample

To run the sample simply execute **WebServiceDemoTestApp** in package *org.springframework.integration.samples.ws*. You can also execute that class using the [Exec Maven Plugin](http://mojo.codehaus.org/exec-maven-plugin/):

    $ mvn clean package exec:java
