The advantage of letting the container (Tomcat) setup a JNDI DataSource
is abstraction. It abstracts out the source of data from the web application.
You no longer have to configure somewhere within your web application the
db connection, user, password, etc.
This allows you to have a developmen
Hi,
A Question about JNDI, to use it i have to configure
it in server.xml file, suppose if i have to change my
app server , say to JRun, or Weblogic or

these are J2EE compliant servers, they must have some
place for defining it,
also what if i ke
Yes, any J2EE compliant app server will have the ability to create
a JNDI DataSource.
The choice of whether to use a container provided DataSource or your
own connection pool within the webapp is up to you.
I prefer a container managed JNDI DataSource.

Using a JNDI Resource, tomcat has connection pooling built-in. Since tomcat
is the reference spec for Java application servers, my guess is that the
pooling in Websphere is simply the same.
Here is the how-to for JNDI:

That would all depend on the pooling implementation you're using.
Commonly, its pool.free(conn) or pool.freeConnection(conn).
Remember *not* to close the connection if you're using connection
pooling, as this should be handled by the pool itself.

depends on what connection pool you use. but in almost all causes, its a pretty
trivial thing (unless your code is funky of course)
in our system, all we did was to switch the driver name (to the pooled driver),
and it would pick up our connection pool.

Because the MySql driver is a javax.sql.DataSource and that's what gets
passed back by the pool, making the pool transparent (no pun intended).
That way you can later change the driver or the pooling details without
changing your code (assuming the SQL dialect still works).

javax.sql.DataSource itself is not returning Connections.
DataSource is an interface -- what this means in practice is that some
random class (in this case, BasicDataSource) is implementing that interface.

The main problem if you are using apache or not, is the "connector". I
don't

the
who needs foreign keys, they only slow your DB down anyway :)
DBCP can support any DB, you will need an ODBC bridge for Access, then you
just give DBCP the odbc bridge driver info, and it should work
