RE: [Embedlets-dev] Building Latest CVS Version Problems

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

I must admit that I develop it based on the version 2 of the embedlet
container prior to the persitance. When I was in there building the
service it really became obvious how important the persistance was going
to be. I noticed you also included some sockets for creating remote
sessions with the container and so-on which is exceptionally nice idea.

I think parts of the technique is similar.. WebService also uses XML as
the return description from the WebService

Basic Concepts

1) WebService - A remote device has a set of webServices which when it
is pinged it returns as an XML WSDL (Web Service Desription Language) -
Actuall what comes out of a uVM device is a very basic XML rather than
the full microsoft WSDL. Muvium now supports webServices transparently -
just extend the WSDL interface and the WebServices are enabled for
remoting those methods - a bit like the [WebService] tag in .Net

2) A RemotingProxy is created by the service which is basically a
wrapper for the HttpGetClientProtocol access to the remote device. If
you look at .net I have basically copied their 'stack' for pluggable
remote service access to allow simple remoting to uVM devices using
Http. Your xml-lite parser would/could come in handy as I use a
ultra-simple specialised parser for results generation right now.

3) The service includes some additional services such as ip scanning for
'discovery' and others.

I will look again for the populated org.japl.net.* stuff but it didn't
come down of CVS from cork nor was it available when I browsed the cork
csv folders.. Perhaps I am crazy

James,

It will be interesting to see your underlying model. The Peristence
model that I submitted uses  an XML packet to accomplish similar
results. Can you give a brief description?
