* The AS400JDBCDataSource class represents a factory for IBM i database connections.
*
* The following is an example that creates an AS400JDBCDataSource object and creates a
* connection to the database.
*
*
* // Create a data source for making the connection.
* AS400JDBCDataSource datasource = new AS400JDBCDataSource("myAS400");
* datasource.setUser("myUser");
* datasource.setPassword("MYPWD");
* // Create a database connection to the system.
* Connection connection = datasource.getConnection();
*
*
* The following example registers an AS400JDBCDataSource object with JNDI and then
* uses the object returned from JNDI to obtain a database connection.
*
* // Create a data source to the IBM i database.
* AS400JDBCDataSource dataSource = new AS400JDBCDataSource();
* dataSource.setServerName("myAS400");
*
* // Register the datasource with the Java Naming and Directory Interface (JNDI).
* Hashtable env = new Hashtable();
* env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.fscontext.RefFSContextFactory");
* Context context = new InitialContext(env);
* context.bind("jdbc/customer", dataSource);
*
* // Return an AS400JDBCDataSource object from JNDI and get a connection.
* AS400JDBCDataSource datasource = (AS400JDBCDataSource) context.lookup("jdbc/customer");
