Need Help About Connection Pooling

Question

I am new to WebLogic.
We have a Java based application hosted on WebLogic 6.1.
We have not used any Database Pooling utility.
We are just creating connection objects in JSP/Java files (Worst!!).
Now we want to use Database Connection Pooling facility of WebLogic.
So now if I create connection pool from WebLogic console, the database connection pooling will be automatically handle by WebLogic OR I have to develop a class using Database Pooling package of the WebLogic and than need to use that class in all file where I am accessing database.
Reg,

Chetan,
Once you have created a connection pool using the console the next thing to do is create a datasource with a JNDIname that uses that pool.
Then you can write a ServiceLocator to use JNDI to encapsulate the lookup code and cache the datasource, finally and you can use the datasource to retrieve connections from your connection pool.
By creating a datasource you decouple your apoplication from connection pools making it more flexible. If you don't like ServiceLocators you can always use something like the spring framework to hide all the plumbing.
For some example code to connect to a datasource see:

For a description of the service locator see:
http://java.sun.com/blueprints/corej2eepatterns/Patterns/ServiceLocator.html
And for completeness
http://www.springframework.org/
