Class BasicConnectionPool

java.lang.Object
  |
  +--gnu.beanfactory.jdbc.BasicConnectionPool

All Implemented Interfaces:

ConnectionPool

Direct Known Subclasses:

BitmechanicConnectionPool

public class BasicConnectionPool

extends java.lang.Object

implements ConnectionPool

Implementation of the ConnectionPool interface that does not implement pooling. This class is useful with batch processing where a pooling mechanism can cause problems. It is also useful in conjunction with the WebLogic connection pool, which exposes itself as a "normal" JDBC driver.
