Calling a datasource

[Brian McGovern]

In my server config file I have a data resource "jdbc/MyData" and in my data 
layer i call it like this.

DataSource zDataSource = (javax.sql.DataSource)zContext.lookup("jdbc/MyData");

This works, but I dont want to hardcode the jdbc name in the data class.  How 
and where do I put this when I am not importing anything into the data class 
besides data specific classes?

Thanks
