Hi,

I am writing a Data Access Layer. At first I made this a Singleton class, so that the same DB connection is used everytime, to avoid creating many connections. Then I changed my code to use DataSource and connection pooling with Tomcat, and now I'm not sure how to go about.

I need the DataSource lookup code to run only once, and use this one DataSource to get connections to the DB. Should I keep the class a singleton?

Not sure if that will work as I am thinking to make my Connection object a member variable.

Below is my current DA class, any advice would be much appreciated:
