Yes, but the internal "container" is very light weight.
So I would say that it is very far from the "almighty Cocoon syndrome".
Ok, sorry for implying that. The only alternative is probably to use
the shared application context as mentioned in the thread about
"interblock communication" [1].
I guess that would mean that each Cocoon block should be a war and have
its own web.xml and application context. I'm not certain that it would
simplify things.
With the current servlet service framework I just don't know how to
integrate JSPs - what this thread was actually about.
Isn't the standard way of integrating JSP to just call it through a
RequestDispatcher that you get from
ServletContext.getRequestDispatcher(String path)? The servlet protocol
just sets up request and response objects and call other servlets
through by the request dispatcher it gets from the current servlet
context. The servlet service fw executes each servlet (service) in its
own context, so you can't access other servlets (or JSP) through the
getRequestDispatcher method. To access other servlet services, one
instead use getNamedDispatcher.
Now currently there is no way to get the original context which is
needed to dispatch to e.g. JSP. But that is of course something that we
should make available. The simplest way to do it would be to have some
reserved name for the original context, "root" e.g. then one could
dispatch to that by asking for a named dispatcher with the name "root"
or by using the servlet service protocol: "servlet:root:/". Implementing
it would, AFAICS, as simple as extending
o.a.c.servletservice.ServletServiceContext.getNamedContext, so that it
returns the wraped root context (super) when asked for "root".
One could also think of registering a special purpose servlet service
that connects to the root context and that servlet services needs to
connect to if they want to call the root context, but I think that would
be overkill.
WDYT?
