JRuby app throws exception in Spring

Question

I am trying to run a JRuby app in Spring. I use Eclipse to run it. But it doesn't compile. Does anybody know what's going on here?

Exception in thread "Launcher:/oflaDemo" [INFO] [Launcher:/oflaDemo] org.springframework.beans.factory.support.DefaultListableBeanFactory - Destroying singletons in org.springframework.beans.factory.support.DefaultListableBeanFactory@4a009ab0: defining beans [placeholderConfig,web.context,web.scope,web.handler,demoService.service]; parent: org.springframework.beans.factory.support.DefaultListableBeanFactory@f5d8d75

I don't have a lot of experience with Spring, so I would really appreciate hits.

If you're familiar with red5 - yes it's the oflademo app supplied by red5.

It's telling you you have a bean defined with the name "web.scope" and whatever application context or annotations it's found is telling it to plug an object with the implementation class org.springframework.scripting.jruby.JRubyScriptFactory into a property of that bean (thje one with the name "web.scope"), where the setter for the property takes a parameter of type org.red5.server.api.IScopeHandler, but the thing being plugged into the property does not implement that interface. In short it's telling you you're putting a square peg into a round hole.

Btw it's a runtime error, not a compile problem.
