ant elder updated TUSCANY-2680:
-------------------------------
Affects Version/s: (was: Java-SCA-Next)
Java-SCA-2.0
> Domain: Webapp scenario
> -----------------------
>
> Key: TUSCANY-2680
> URL: https://issues.apache.org/jira/browse/TUSCANY-2680
> Project: Tuscany
> Issue Type: New Feature
> Components: Java SCA Core Runtime
> Affects Versions: Java-SCA-2.0
> Environment: windows
> Reporter: haleh mahbod
>
> 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.
