Specify the parser in the server-side toolkit configuration file
(dse.ini) for the appropriate device handler. This allows the parser to be
dynamically created at runtime.
Configure the channel handler in the server dse.ini file for the
device type with the registered handlers and optional parameters.
Establish the session between the client and the server by invoking
the XmlEstablishSessionServlet using the "GET" or "POST" protocol. The session
ID must be sent as part of the XML message and all subsequent requests. This
can be sent as part of the HTTP request header or in the XML message. Passing
the session ID is not required if all operations are to run out of session.
Ensure that the XML message format is validated against the DTD.
This step will be performed automatically by the toolkit if you are using
the XML for Java™ Parser. The current DTDs are expected to reside
in the root directory.
