Examples of org.apache.tomcat.jdbc.pool.DataSourceProxy

org.apache.tomcat.jdbc.pool.DataSourceProxy
The DataSource proxy lets us implements methods that don't exist in the current compiler JDK but might be methods that are part of a future JDK DataSource interface.
It's a trick to work around compiler issues when implementing interfaces. For example, I could put in Java 6 methods of javax.sql.DataSource here, and compile it with JDK 1.5 and still be able to run under Java 6 without getting NoSuchMethodException. @author Filip Hanik @version 1.0
