In the above output from your generator, you need to reference the
actual resources of the listed servlet services. And to be able to do
that you need an URI.
The URI is data/myconfig.xml, resolved against all available servlet
services.
And right now we have not any protocol that is suitable for that.
AFAIU we only have to create ServletConnection objects. Currently the
constructor expects the connection name as parameter but it shouldn't be
difficult to create those objects by implementing a second constructor
that uses the bean id or a bean reference.
For the use case we are discussing, the assumption is that the caller
of the servlets generator is not connected to all the servlet
services. Thus we cannot use the servlet: protocol that by design
assumes an explicit named connection.
So we need a protocol that allows (webapp) global servlet service URIs
anyway. And then we could as well make it listable as a source is
usable in more contexts than a generator.
ok. What I still don't understand is, why we want to make the bean id
being part of this URI at all? Or do I misinterpret your discussion with
Grek here?
I guess that main reason is that we need unique URIs.
Isn't having an URI
servlets:/data/myconfig.xml
good enough to configure a listable source? The getChildren() method of
the created source will return all child sources that return true on
childSource().exists().
What would "servlets:" source return if getInputStream() was called for
"servlets:/data/myconfig.xml" URI?
I don't see the need to lookup not configured servlet services by their
name. The only use case I can think of is optional servlet services. To
solve it, I'd rather introduce an "optional" parameter for servlet
service configurations. However, I'm not convinced that we need this
feature at all if we can resolve servlets:/data/myconfig.xml URIs which
would return servlet service sources that are unknow in the context of
the current servlet service.
I can't parse the above. What does mean "to lookup not configured servlet services
by their name"? How they can be not configured?
