Many provider URLs in jndi.properties?

Hi,

I am deploying a J2EE application on Oracle IAS.
I need the same EAR file to be deployed on many environments (client
requirement for deployment automation).

I thought about passing the "environment" parameter to the JVM, for
retrieving a custom PROVIDER_URL value from my jndi.properties file, which
is containing all needed provider URLs.

For example :
java.naming.provider.unit.url=iiop://myserv1:27001
java.naming.provider.fonc.url=iiop://myserv2:27002
java.naming.provider.acce.url=iiop://myserv3:27003
java.naming.provider.prod.url=iiop://myserv4:27004

I don't know how and when retrieving that custom PROVIDER_URL key associated
value... is the retrieving operation of standard "java.naming.provider.url"
immutable and implicit to the J2EE container?

Any help would be appreciated...

Martin.

My? So, is this jndi.properties file included in the application?

My opinion lately has been that the less information applications have
about their environment (such as supporting servers, port numbers, ...),
the better. Environment information is then provided to the application
at installation/deployment time.

Not my jndi.properties file, but the one in the services library, which is
part of the EAR to deploy.

I agree with you about the applications and their environment infos, but it
is a requirement...

Still searching a solution, if you have any suggestion... Thanx.
