Subject Re: Dynamic web services in AXIS
Date Wed, 15 Oct 2003 23:34:17 GMT
Hi,
I have also come across similar requirements for implementing WSMF 
(http://devresource.hp.com/drc/specifications/wsmf/index.jsp ). In this 
specification, each managed resource is represented by a managed object (Web 
Service) of its own. In certain applications, the number of managed resources 
is quite large and they come-and-go quite often. Full fledged Axis web services 
do not seem to make sense for representing such light-weight web services.

I am trying to simulate multiple web-services within a single Axis Web Service 
by constructing URL addresses that have a QUERY_STRING. However, this screws up 
WSDL generation (currently, I have a seprate Servlet to take care of WSDL 
generation). The other issue I see is if and when I decide to use HTTP GET 
binding.

Regards,
Pankaj Kumar.
