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

James,

Sounds like we should put our heads together on this. The persistence model
serializes/deserializes objects to XML and provides remote property setting.
It does a crude form of remote invocation using a command tag inside of the
Request packet. The container parse the Request and sends back either a
Response object or the serialized component if the Request identity targets
a component.

A standard web services interface would greatly boost acceptance and
sercurity and could, I believe, support the existing persistence by wrapping
the serialized packets in a web services envelope.
