http:inbound-channel-adapter view problem

[rpssk]

Hi

I'm setting up an “http:inbound-channel-adapter” where I need to format validation messages to be sent back to the client and I'm having problems defining the view-name attribute.

I have:

<http:inbound-channel-adapter id="httpInboundAdapter"
channel="requestChannel"
supported-methods="POST"
message-converters="stringMessageConverter"
request-payload-type="java.lang.String"
view-name="myView"
/>

On the web.xml I have

<servlet>
<servlet-name>httpInboundAdapter</servlet-name>
<servlet-class>org.springframework.web.context.support.Http RequestHandlerServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>ordersInboundAdapter</servlet-name>
<url-pattern>/rest/*</url-pattern>
</servlet-mapping>

when I don't define the view-name, it works but on a validation error, it just sends back to the client the stack trace. When I add the view name, then it stops working and send the following error:

org.springframework.beans.factory.BeanNotOfRequire dTypeException: Bean named 'httpInboundAdapter' must be of type [org.springframework.web.HttpRequestHandler], but was actually of type [org.springframework.integration.http.inbound.HttpR equestHandlingController]

Does anybody know why? Is there any example of how to set up a “http:inbound-channel-adapter”.. maybe its the way I have set it up on the wed.xml file...

Any pointer will be much appreciated.

Thanks

The basic idea is that the 'view-name' support builds upon Spring MVC functionality. So, you would setup a Spring MVC DispatcherServlet (and potentially an explicitly configured ViewResolver). When not using a view, the MVC base is not required, and that is why the simple delegating Servlet option works in that case.

Does that help?

Thanks Mark for you answer, it makes perfect sense.
