Best way to store your database connection is
- Configure DataSource & ConnectionPool on application server.
- Make use of JNDI to obtain DataSource.
- Properties file for database connectivity.
- XML file database connectivity.
For reading property file you can make use of java.util.ResourceBundle and any XML parser like X-Stream for XML parsing.
Though if you want can make use of your web.xml to store database connection configuration parameters.
For global variable you can use simple a Constant class where you can define those variable and can use them throughout your application.
