In the past, I used to make use of connection pool when connecting to MySQL using Servlet; now, I will connect Oracle via Servlet, I wonder if I still need to make a connecting pool in Servlet? Or Oracle already have this kind of function so that I don't need to take care of this when programming? Thanks

It's my understanding that a DataSource is the preferred way to connect to a database from Servlets. It will do it's own pooling, so you don't have to worry about it.
