Creating a Driver DataSource Object

The following Java code example creates a DataDirect Cloud Driver for JDBC DataSource object and registers it with a JNDI naming service.
Note: The DataSource class implements the ConnectionPoolDataSource interface for pooling in addition to the DataSource interface for non-pooling.
//************************************************************************
// This code creates a DataDirect Cloud Driver for JDBC data source and
// registers it to a JNDI naming service.
//
// This data source registers its name as <jdbc/CloudSparky>.
//
// NOTE: To connect using a data source, the driver needs to access a
// JNDI data store to persist the data source information.
// To download the JNDI File System Service Provider, go to:
//
//http://www.oracle.com/technetwork/java/javasebusiness/downloads/​java-archive-downloads-java-plat-419418.html#7110-jndi-1.2.1-oth-JPR
//
// Make sure that the fscontext.jar and providerutil.jar files from the
// download are on your classpath.
