Hi all,

I just came accross a limitation (bug) of GlassFish : adding
a @DataSourceDefinition on a CDI bean doesn't work in an embedded
environment (
I had to put it in the EJB to make it work.

Why do I use @DataSourceDefinition on a CDI bean instead of an EJB ?
Because I thought I could use alternatives (i.e. defining several data
sources depending on the environment). But this doesn't work in CDI 1.0 (

Alternatives should work on definitions, don't you think ? In other specs,
are you aware of other kind of definitions (I know that JMS 2.0 will bring
similar features with @JMSConnectionFactoryDefinition and
@JMSDestinationDefinition) ? If yes, we should encourage the spec leads to
use similar behavior.

My 2 cents
