19.4.1 Exposing the service object with spring mvc doesn't work

To expose the AccountService (mentioned above) within a Spring Web MVC DispatcherServlet, the following configuration needs to be in place in the dispatcher's application context:

HTML Code:

---

<bean name="/AccountService" class="org.springframework.remoting.httpinvoker.HttpInvokerServiceExporter">
    <property name="service" ref="accountService"/>
    <property name="serviceInterface" value="example.AccountService"/>
</bean>

---

Such an exporter definition will be exposed through the DispatcherServlet's standard mapping facilities, as explained in the section on Hessian.

This I can't make it work.

I manage to make work the alternative way by declaring in the web.xml

HTML Code:

---

<servlet>
    <servlet-name>accountExporter</servlet-name>
    <servlet-class>org.springframework.web.context.support.HttpRequestHandlerServlet</servlet-class>
</servlet>

---

but the first mentionned way doesn't work, it's not automagically bound to an already existing spring mvc dispatcher servlet

after debugging spring I finally found I needed to instanciate in the spring servlet context xml
<bean class="org.springframework.web.servlet.mvc.HttpReq uestHandlerAdapter"/>

please update the docs, how can we guess this is needed ?

javax.servlet.ServletException: No adapter for handler [org.springframework.remoting.httpinvoker.HttpInvok erServiceExporter@f80123]: Does your handler implement a supported interface like Controller?

it says there is no adapter as if it's definitive and doesn't say you might just instantiate some appropriate adapter that will register themselves automagically
