The gwtrpc-spring jar allows for simple integration of Spring and GWT 1.6. Instead of having a separate servlet for each service there is one RemoteServiceServlet that looks the configured SpringContext for a instance of a class that implements the Remote Service. So that means your services don't have to inherit RemoteServiceServlet just implement your RemoteService interface. That means any Spring POJO can become a Gwt RPC Service.

To set it up:

1. Add the gwtrpc-spring jar to your /war/WEB-INF/lib directory

2. Add the spring jars to to your /war/WEB-INF/lib directory (i.e. spring-core.jar, spring-beans.jar, spring-context.jar and spring-web.jar) 3. Edit your web.xml to add the dispatcher servlet

	<servlet>
		<servlet-name>dispatcher</servlet-name>
		<servlet-class>
			org.gwtrpcspring.RemoteServiceDispatcher
		</servlet-class>
	</servlet>

4. Edit the web.xml to add the Context Listener

	<listener>
		<listener-class>
			org.springframework.web.context.ContextLoaderListener
		</listener-class>
	</listener>

5. Edit the web.xml to add servlet-mappings for the services to the dispatcher

	<servlet-mapping>
		<servlet-name>dispatcher</servlet-name>
		<url-pattern>/myapp/greet</url-pattern>
	</servlet-mapping>

6. Create an applicationContext.xml with your services defined.

<?xml version="1.0" encoding="UTF-8"?>
<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.xsd">

	<bean id="greetService" class="org.gwtrpcspring.example.server.GreetingServiceImpl">
	</bean>

</beans>

That's all it takes.
