I'm developing a simple application. I'll like to implement the connection pooling in my application. When i searched the net i can able to see lot of examples but at end of the session i'm not able to understand even a single method.. Could any please explain me which is best and we can go for it..
Which connection pooling library were you looking at? Typically there is only one method - getConnection() if that. Most of the time there is just a connection pool driver. You say how many connections you want and everything happens behind the scenes.
A common free one used in the Java world is Apache Database Connection Pool (DBCP). http://commons.apache.org/dbcp. This is specifically for pooling of data sources and builds on the common pool library which provides generic object pooling functionality.
DBCP has a couple of versions, 1.4 is for Java 6 and 1.3 for Java 5 and earlier. It comes with a good set of examples and there is plenty of reference material on the web.
As to your post, were you looking for a recommendation then I can say I have used this before. If you need examples of how to use it, I would look first in the examples.
