No, it's not possible. For this to make sense you would be setting up a
transaction manager and connection pool on your client. You should configure
these explicitly in your client along with the datasource.
In trunk we have recently added support for looking up @Datasource defined
datasources set up in the java:global namespace from javaee 6 geronimo app
clients. In this case the transaction manager is already set up and accessible
in a known way and we only have to set up the connection pool. I don't think
doing this is ever a very good idea, but it's required by the ee6 spec.
