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)?

yes.

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.

not in the same classloader, but just as with the datasources this works fine with the "same" class in different classloaders.

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)

Collecting the jars needed for a particular driver to work can't be done in any automatic uniform way at the moment AFAIK. So we either have to show all the jars and let the user pick or require that some person figure out and install the metadata for each driver. My experience is that a metadata based solution will never be kept up to date.

I thought that a search feature that would find all the jars containing a particular class, given the fully qualified class name, was a reasonable compromise between having to look through all the jars with no clue about whats inside and hiding most of the jars based on what is sure to be out of date information.

Just remember that one of the main reasons that there's an awkward
display of tons of JARs now is that the DB2 driver (did?  does?)
require 3 JARs to all be added in order to function, and only one of
those has any kind of driver implementation AFAIK.  (I think one is a
license and not sure about the other.)  I think there is at least one
other multi-JAR driver out there too.

I think it would be nice if we showed a single combo box, perhaps with
just the driver JARs listed, and then had a checkbox where if you
clicked it then the page would adjust to let you select multiple
arbitrary JARs instead.

Thanks,

Well anyway, if you are going to filter by the class, you still have the "problem" of not seeing all its dependent classes/jars... But I really think
it shouldn't be a big deal in this context.

Talking about the performance hit related to this kind of filtering, it can be avoided if you keep track of those classes since you install it into your
repository folder. What do you think about it?

This initial idea in terms of filtering aims to make the information shown really useful to the console user (system operators and developers)...

And instead of just filtering the java.sql.Driver implementations, it could
be instructed to look at XAResource implementations as well...

David Jencks commented on GERONIMO-3106:
----------------------------------------

What we have now is surely annoying and hard to use, but there are at least
2
problems with the proposal:

1- it wouldn't show a jar that had an xa-only datasource implementation with
no Driver implementation
2- it wouldn't show utility jars that might be needed by some drivers

So, an option to filter the jars might be useful but it would certainly slow
down the ui and you'd need to be able to turn it off.

Perhaps a "find the jars containing this class" button would be useful?

When you are in the Create Database Pool wizard the jar driver list could
show only jars containing Driver implementations

URL: https://issues.apache.org/jira/browse/ GERONIMO-3106
            Project: Geronimo
         Issue Type: Improvement
     Security Level: public(Regular issues)
         Components: console
   Affects Versions: 2.0-M3
           Reporter: Daniel Alheiros
           Priority: Minor

The combo actually shows all the repository jars but could be organized in
an
easier way if are shown only the repository jars containing java.sql.Driver
implementations.
