RE: [uddi-dev] Multiple access points II

[Ramesh Sakala <rsakala@digev.com>]

While we are on this topic, I would like to ask a related question.

What is the suggested modeling approach for two load balanced services?
If two services are load balanced, do we create two business services
with each one having the access point for one service or do we create
two binding templates in one business service representing each access
point?

Because both of these services (access points for the same service)
implement the same interface, they have essentially one WSDL.

Any insights would be helpful...

Thanks,
Ramesh.

Paul,

The new Technical Note on using WSDL and UDDI, being developed by the
OASIS
UDDI Specifications Technical Committee, restricts a UDDI
businessService to
represent at most one WSDL service so if Explode is one WSDL service and
Implode is a different WSDL service then they should be represented as
different UDDI businessServices.

This Technical Note should be released in the not-too-distant future.

Hi,

Second question regarding multiple access points per service. A proposal
has
come up to allow someone to register a service and have multiple
accessPoints for the service.  The issue here is that each accessPoint
points to a different service.

Let me give an example:

The service is registered as Bill of Materials.  It has two
accessPoints:

Bill of Materials Explode
http://hostname/bomExplode

Bill of Materials Implode
http//hostname/bomImplode

These are two different services with different associated WSDL docs.

I am personally uncomfortable with this model because I believe that
each
businessService should be mapped to one service implementation. I feel
that
BOMExplode and BOMImplode are two different services and should be
registered separately.

However, I would like here what your experience and opinions are in this
area.

If this model is acceptable, how do you find a specific accessPoint
programmtically (JAXR) in UDDI v2.0?  Do you use the
tModelInstanceDetails
object?

Any feedback in this regard would be very helpful.

Thanks,
Paul
