Or is a Service really just a Container?
Speaking in definitions, a Service is a Component that performs an
action (as
opposed to represent a thing like EntityBeans).
Services would include your different J2EE containers, and the things
that
they do.
Surely then it makes it desirable to have a 'Thing' and 'Service'
supertypes to distinguish between them?
I'm not sure what you mean by 'Thing' here, but JSR77 makes a
distinction between a resource and an instance of a resource (a
service). So they have things like a JDBC Driver (a resource) and a
JDBC connection pool (a service). Is that what you mean?
Essentially yes.
I.e. the difference between a URL and a URLConnectionHandler (on the microscale
service).
