conflict between hessian remoting and <mvc:annotation-driven />

[luca.preziati]

I have declared some expose bean,

	<bean name="/CoreChecklistService" class="org.springframework.remoting.caucho.HessianServiceExporter">
		<property name="service" ref="coreChecklistService" />
		<property name="serviceInterface" value="it.ubiss.gedi.gfs.service.CoreChecklistService" />
	</bean>

Now I need to declare a spring controller and add <mvc:annotation-driven />

So remoting bean are not more reachable.
Why????

Web.xml

<servlet>
		<servlet-name>remoting-servlet</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>
				/WEB-INF/spring/application-config.xml
			</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>
	<servlet-mapping>
		<servlet-name>remoting-servlet</servlet-name>
		<url-pattern>/hessianRemoting/*</url-pattern>
	</servlet-mapping>

Use [ code][/code ] tags when posting.

Remoting doesn't work anymore because the DispatcherServlet doesn't know what to do with it (anymore). This is due to the annotation-driven namespace, it registers 2 HandlerAdapters which override the defaults. Next to mvc:annotation-driven also include a HttpRequestHandlerAdapter.

Sorry for code tags, I didn't know that exist, but I corrected the post.

I have declared a bean as follow:

  <bean id="httpmapper" class="org.springframework.web.servlet.mvc.HttpRequestHandlerAdapter">
  </bean>

but now I don't reach nothing

No mapping found for HTTP request with URI [/gedi-gfs-webapp/hessianRemoting/clearTypeRegistryCache.htm] in DispatcherServlet with name 'remoting-servlet' my controller
No mapping found for HTTP request with URI [/gedi-gfs-webapp/hessianRemoting/pdc/Search] in DispatcherServlet with name 'remoting-servlet' my hessian element

Should I attach the bean to servlet?

You also need a BeanNameHandlerMapping to map the beanname to a url (which is what you want for the Hessian stuff).

[luca.preziati]

This is the solution:

add the following bean, one required by the annotated spring controller, another one required by Hessian Remoting

 <bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">
    <property name="order" value="1" />
  </bean>
  <bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping">
    <property name="order" value="2" />
  </bean>

In any case I think the documentation doesn't contain this aspect: expose Hessian bean and have a administrator front end on the same webapp can be useful: in my case I have t clear cache for exposed bean
