Subject Re: [jira] Commented: (GERONIMO-3106) When you are in the Create Database Pool wizard the jar driver list could show only jars containing Driver implementations
Date Thu, 19 Apr 2007 09:08:22 GMT
Sorry for the ignorance, but I'm a but confused about this jar selection...
Does it allows me to have more than one driver version for the same vendor
(like having a Oracle 8i and Oracle 10g drivers at same time being used by
different datasources)? If not, what is the point in selecting the JAR in
this form?

Does the Geronimo's classloaders allows me to have "one" class in different
versions available? I don't believe it could be managed safely, so I believe
it doesn't.

I like the idea of having a list containing eventual implementation options,
because it is much easier to take a look in an existing environment and be
aware of what drivers are available and avoid eventual incompatibilities
changing drivers (like Oracle 8i and Oracle 9 or 10g drivers)

Regards
