All Implemented Interfaces:

Wrapper, CommonDataSource, DataSource

public class JPPFDataSource
extends Object
implements DataSource

A non-pooled, non-XA datasource that provides connections using the DriverManager API. The JDBC driver and connection information are retrieved from the JPPF configuration, for example:

 # Datasource name
 jppf.datasource.<configId>.name = myDS
 # JDBC driver class name
 jppf.datasource.<configId>.driver.class = com.mysql.jdbc.Driver
 # Database connection user
 jppf.datasource.<configId>.user = testjppf
 # Database connection password
 jppf.datasource.<configId>.password = testjppf
 # Database connection url
 jppf.datasource.<configId>.url = jdbc:mysql://localhost:3306/testjppf
