An implementation of com.mysql.jdbc.ConnectionPropertiesTransform that the driver will use to modify URL properties passed to. For more information, see “Integrating the JDBC Driver" in GlassFish Server Open Source Edition Administration Guide, available at GlassFish Server Documentation. You are now ready to create JDBC Connection Pools and JDBC Resources. Creating a Connection Pool. In the GlassFish Administration Console, using the. When you are using JDBC outside of an application server, the DriverManager class manages the establishment of connections. Specify to the DriverManager which JDBC drivers to try to make Connections with. The easiest way to do this is to use Class.forName() on the class that implements the java.sql.Driver interface. setDriverClassName("com.mysql.jdbc.Driver"); dataSource.setUrl("jdbc:mysql://localhost:3306/data"); dataSource.setUsername("USERNAME"); dataSource.setPassword("PASSWORD"); } private Database() { // } public static Connection getConnection() throws SQLException { return dataSource. These jars need to be in the CLASSPATH, apart from MySQL JDBC driver. package org.mano.example; import java.beans.PropertyVetoException; import java.sql.Connection; import java.sql.SQLException; import com.mchange.v2.c3p0.ComboPooledDataSource; public class C3P0DataSource { private. Step 1a: Manually Adding the MySQL driver to the GlassFish Domain. Before we even start NetBeans we must do a bit of preliminary work. With the exception of Derby, GlassFish does not include the MySQL driver or any other driver in its distribution. Go to the MySql Connector/J download site at. I have implemented a MySQL Connection Pool in Java by using GenericObjectPool that provides robust pooling functionality.
