Bean database access concepts

[Joao Araujo <jo...@wireless-networks.com>]

	
	I am not using EJB but plain beans to access the database.
	I defined everything in such a way to isolate  database access from action 
bean.
	Now, I have some doubts about how to access the database connection.
	Should I pass the connection as a parameter to the beans that accesss the 
datdabase, or
	should I use another method?

	Thanks a lot for your attention,


Joao,

Bean does not access the db!

DAO access the db. (DAO can be implemented several ways)
Bean has a DAO helper.

DAO can get JNDI pool from container or make its own pool, based on 
properties.

Also, you should be able to unit test you beans for CRUD.

I wonder where the sample code that does this would be? I know, if I go 
to struts resources page and look for a DB sample, that would do it.

JNDI is a pretty good way to get connections.  You'll probably want to 
provide alternate signatures of your methods for allowing a connection 
to be passed to a "save" method though - so you can involve multiple 
beans in a single transaction.
