Hi,
I am not sure if DataDirect Driver is expected to work with WmDB package.
Most likely it will only work the WmJDBCAdapter package.
JDBC Pool Alias for internal functions is considered as embedded application.
Please check if it is really neccessary to use WmDB package for your custom implementation.
Most likely you want to redesign it to use WmJDBCAdapter package to benefit from the DataSource approach with Connection-Pooling facilities.

Holger
