Service Locator for versioned services

Service Locator for versioned services

Good morning people.

I'm hoping that some of you can help stimulate ideas in my mind with regards
the Service Locator.

After writing an initial application which was all contained in one large ear,
we have recently embarked on a process of splitting up the application into a
number of services each of which have their own ear. Now that the next
application is in development and modifications need to be made to the base
services we would like to deploy different versions of the same service. So we
deploy two ear files.

service-1 (See http://ice-1.ora-code.com).0.ear
service-2 (See http://ice-2.ora-code.com).0.ear

and within them we have JNDI names something like

/CompanyName/ServiceName/VersionNumber/ejb

I would like to include a properties/xml file as part of the deployment for my
application that says it should use version 1.0 of service X and version 1.3
of service Y etc and have the Service Locator use this file to look up the
correct version of the EJBs.

Have people done or thought about this before?

Are there any resources about that can help me? (I can not find anything on the
Sun Java site)

Does anyone have any words of wisdom for me?

Any help is most appreciated

Thanks in advance
IV
