> Message heading on ml:: Question on Tomcat / webapp support in SCA Java
> High level: I'd be interested if other users have any cases where multiple webapps would have to access a
> single SCADomain containing back-end services in the same JVM as the web container.
> Detail: 
> know it has been a while since we exchanged information on this thread, but I wanted to
> point out that the scenario we want to support, which is a single SCADomain in the JVM
> supplying services to multiple webapps is similar to a case that Spring Framework already
> supports, which is sharing a parent application context across multiple webapp application
> contexts.
>  
> In the Spring case, they have this thing called SingletonBeanFactoryLocator that, from
> any number of webapp application contexts, can locate the back-end services application
> context.  This can be made the parent context of the webapp contexts, which makes the
> back-end context beans available to the webapps.
>  
> Here's a link to a web page that describes it:
>  
> http://blog.springsource.com/2007/06/11/using-a-shared-parent-application-context-in-a-multi-war-spring-application/
>  
> It would be really nice if Tuscany could support something similar to this for SCADomains
> to allow multiple wars to reference the same set of SCA components and services.
>  
> I also don't mind at all having to configure Struts to delegate everything through Spring to do
> dependency injection, and I would also not mind having to do this to get SCA to inject service
> references.  This would be better than requiring a modified Tomcat runtime with "deep SCA
> integration", at least for our purposes.
>  
> I'm curious if there has been any progress in the area of shared services in the same JVM as
> multiple wars.  If so, can you send me a pointer?
>  
> Thanks.
