Re: [Springframework-developer] Access to ServletConfig in WebApplicationContext

[Juergen H. <ju...@in...>]

At the core web MVC level, such an abstraction is arguably not worthwhile.

The control flow in a Portlet environment is quite different, which needs to
be reflected in the corresponding controller model. Furthermore, web
controllers should have full access to the native Servlet/Portlet
facilities, not just to a least common denominator.

On the view side, we have full reuse anyway, so it's really only about the
dispatcher / controller side, including handler mapping and co.

Higher-level web UI frameworks such as Web Flow, JSF or Tapestry are a
different matter here. To a large degree, they abstract from the underlying
request model, so can more naturally abstract from the concrete
Servlet/Portlet facilities, or in fact even the dispatcher facility they run
in.

Sounds good to me... While you are at it have you considered if it's
possible to abstract the http and portlet request and response similar to
webflow so that the code doesn't have be so duplicated?

Subject: [Springframework-developer] Access to ServletConfig in
WebApplicationContext

I posted a question about this to the user list last week and no one had any
secret tricks for this, so I'd like to propose a minor change to
WebApplicationContext and to FrameworkServlet as follows:

I'd like to provide beans running in a WebApplicationContext with access to
the ServletConfig that they are running in.  I'd like to do this in order to
provide access to the portletName and the initParameters for the Servlet.  I
know several other developers have expressed an interest in this.

This can be done in the same way that Spring currently provides access to
the ServletContext.  In fact, we can also provide a ServletConfigAware
interface and inject the ServletConfig directly into any bean that wants it.

I will then also provide equivalent functionality in the Portlet MVC code so
that beans running in a PortletApplicationContext have access the
PortletConfig they are running in.  I'd like to do this in both frameworks
in order to keep them relatively synchronized.

Any objections to all this?

Juergen, I'd be happy to email you the code prior to committing it into CVS
if you would like to review the changes first.  Please let me know.

Thanks for your support.

John Lewis
