Hi

Basically i have a web.xml with roughly the same structure as the greenpages demo app:

...
	<context-param>
		<param-name>contextClass</param-name>
		<param-value>org.eclipse.virgo.web.dm.ServerOsgiBundleXmlWebApplicationContext</param-value>
	</context-param>

	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
	<servlet>
		<servlet-name>novonet</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
	</servlet>


 	<servlet-mapping>
		<servlet-name>novonet</servlet-name>
		<url-pattern>*.do</url-pattern>
	</servlet-mapping>

I have my applicationContext.xml where i use the osgi namespace to identify a list of services:

	<osgi:list id="messageSourceList" cardinality="0..N" interface="org.springframework.context.MessageSource" context-class-loader="service-provider" filter="(name=portal)" />

and then my novonet-servlet.xml where I try to use this bean:

	<bean name="messageSource" class="com.ibm.healthconnect.modules.HealthConnectMessageSource">
		<property name="messageSources" ref="messageSourceList" />
	</bean>

but when running the application i get the following (as if the servlet context cannot see the application context) - what is going on?

Hmm...could be due to the fact that I'm using Snaps.
I found http://dev.eclipse.org/mhonarc/lists/virgo-dev/msg00366.html and this seems to indicate this.

Snaps is the reason you are seeing this.

With snaps you should only use DispatcherServlet app-context not the root.webapp context (the one listener sets up).

Because you are attaching to the context or the host web application, there needs to be some level of scoping done on the servlet context attributes.
