- All Implemented Interfaces:
Serializable
,AutoCloseable
,Wrapper
,Referenceable
,CommonDataSource
,DataSource
A pooling DataSource
appropriate for deployment within
J2EE environment. There are many configuration options, most of which are
defined in the parent class. All users (based on username) share a single
maximum number of Connections in this datasource.
User passwords can be changed without re-initializing the datasource.
When a getConnection(username, password)
request is processed
with a password that is different from those used to create connections in the
pool associated with username
, an attempt is made to create a
new connection using the supplied password and if this succeeds, idle connections
created using the old password are destroyed and new connections are created
using the new password.
