[prantik bordoloi]

can somebody please help me in making a connection pool class for postgresql using type 4 driver. if the possible a sample code !!
where can i get some good coding examples of connection pooling in the net ?

Prantik,
what JDBC drivers are you using? Most likely, if they are JDBC 2.0 compliant, they come with an implementation of the <code>javax.sql.ConnectionPoolDataSource</code> interface, which can be be used for connection pooling.

Not necessarily. The <code>javax.sql.ConnectionPoolDataSource</code> interface is not part of JDBC 2.0 Core. It belongs to the JDBC 2.0 Optional Package (a.k.a. Standard Extensions). Therefore, if it doesn't support the JDBC 2.x spec, you can either write your own connection pooling framework or use an existing one such as PoolMan, which is free and open source.
