Newb JDBC Connection best practice

amy

I have inherited a web app that uses a SingleConnectionDataSource, which I just read in the docs is quot;not multi-threading capablequot;.  
I am concerned about the scalability of the app as it will be public facing.  Could someone suggest best practice for connection and connection pooling in Spring, please?
If I want this app to be 'multi-thread capable', what Spring Connection class should I migrate the app to?  Is there a standard for quot;productionquot; use?

Thanks.
