I will be writing a web app that hits an oracle db. I plan to use the oracle oci drivers so that I can use proxy authentication. My web server is the Sun Java System Web Server 6.1, and we use it's internal app server capabilities for our app server. I had planned on manipulating the oracle connection pool directly from java code using the oracle supplied driver and classes. However; I see that I can define a connection pool to my app(web) server. I assume this would let me use JNDI to get my datasource. Big deal. Any other reasons? I'm leaning toward not defining the connection pool to my web server.
Marshall, It is best to let the app server handle the connection pool and use datasources. Why would you want to write something that the app server already does?
