getConnectionProperties

protected Properties getConnectionProperties(Subject subject,

                                      throws javax.resource.ResourceException

Gets full set of connection properties, i.e. whatever is provided in config plus "user" and "password" from subject/cri.

Note that the set is used to match connections to datasources as well as to create new managed connections.

In fact, we have a problem here. Theoretically, there is a possible name collision between config properties and "user"/"password".

Throws:

javax.resource.ResourceException
