UWS SOAP

[Dave Morris]

It is possible to do this fairly easily in Java.

In our VOSpace implementation one webapp can provide multiple VOSpace 
webservices.
The SOAP endpoint URLs contain the target identifier.
For example, if I have service identifiers 'abc' and 'xyz', then the 
SOAP endpoints would be :
    http://hostname/context/services/abc
and
    http://hostname/context/services/xyz

All http post requests are passed to a simple http servlet at
    http://hostname/context/services/*
the servlet extracts the identifier from the URL (e.g. 'abc' or 'xyz') 
and then passes the request on to the Axis SOAP servlet.

Alternatively, you can just read the http URL from the HttpRequest 
object from within the Axis service code itself.
Either of these techniques mean you can create a unique SOAP endpoint 
for each job and handle them with the standard Axis SOAP servlet.

Hope this helps,
Dave
