War not "Spring Powered" despite using lots of spring [message #1030169]

Hi, I've upgraded Virgo 3.5's Spring to 3.1.3.RELEASE but I don't know if that upgrade is relevant to this problem.
I've built a war which seems to work fine, with Spring - however, it's marked as "Spring Powered: No" in the admin console. I've only noticed this because I came to investigate if a bean I was making was actually being created. By this stage though, I've used a whole bunch of spring things successfully, including Spring Security, Spring Social, Spring JPA, Spring MVC... etc.

The configuration files involved are quite large so I can't really attach them. However, previously, I've noticed some of the following configurations have prevented bundles from utilising Spring.
Manifest:

Import-Library: org.springframework.spring;version="[3.0, 3.2)"
Import-Package: org.eclipse.virgo.web.dm;version="[2.0.0,3.6.0)"
Bundle-ClassPath: .,WEB-INF/classes

Web.xml:

    <!-- Creates the Spring Container shared by all Servlets and Filters -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath*:META-INF/spring/applicationContext*.xml</param-value>
    </context-param>

So the question is, what else does the "Spring Powered" detection rely on?
Thanks, Dan.

  public String getSpringName()
  {
    Bundle realBundle = this.quasiBundle.getBundle();
    if (realBundle != null) {
      ModuleContext moduleContext = this.moduleContextAccessor.getModuleContext(realBundle);
      if (moduleContext != null) {
        return moduleContext.getDisplayName();
      }
    }
    return "";
  }

I got this far, but by this stage I don't really know what I'm looking at. Is there a way for me to put a breakpoint or something in this via Eclipse?

Thoroughly embarrassing!

Missing:

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

I came back to this post to see if there were any replies, and happened to look at the web.xml I posted and knew immediately it wasn't right... I'm so used to relying on OSGi that I assumed the line above was so essential that nothing could be working without it. However, I haven't split this project out yet so haven't used any OSGi from Spring yet - I guess that's why it was able to work?

Humbly,
Dan.

Thanks for posting the fix. Responses were probably slow due to some of us being at EclipseCon. Glad it's all working now.

The idea of the forum is that the user community can help itself which often works, but not always. Every so often, we committers tend to have a look at unanswered threads and if we can add any value, make a comment.
