Return the primary data source to use. The data source will automatically use the given context's user name and password on calls to DataSource.getConnection(). If the given context is null, the data source will use the configuration's default connection user name and password. If those too are null and the first context has been obtained already, then the user name and password for that context will be used, as we know they represent a valid combination. This method avoids casting the result of OpenJPAConfiguration.getConnectionFactory(), and avoids having to pass in the user name and password to obtain connections.


getDataSource2

DataSource getDataSource2(StoreContext ctx)
Return the non-enlisted data source to use. If there is a valid non-xa connection factory configured, then it will be returned. Its default user name and password on calls to DataSource.getConnection() will be the specificed connection 2 user name and password. If those are null and the given context is non-null, its user name password will be used instead. If the context is null too, then the user name and password used to retrieve the first context will be used. If there is no second connection factory the primary connection factory is used.
