Subject SOAP Semantics
Date Tue, 30 Apr 2002 12:20:41 GMT
  The SOAP processing rules in v1.2 are pretty clear that
all headers *and body* that are targeted for this Node
must be understood before *any* processing can begin
(we'll leave out the notion of 'undo' for the moment).
  In a typical Axis deployment where something like the
URL mapper is used, Axis "assumes" that if there's a
mapping from the URL to a service that it "understands"
the Body.  This technically isn't true.  If the URL
has  .../services/StockQuote but the Body has a
QName of   .../PurchaseOrder then there's an error but
the error will not be noticed until *after* processing
has begun (and after the Handlers have been invoked)
which violates the SOAP rules.
  It seems like Axis needs to have a QName associated
with each service so that the AxisServer can verify that
the QName of the Body is "understood" before _any_
processing begins.
