Derby - Connection with DataSource Objects

This section describes options of using DataSource objects to create database connections.

As I mentioned earlier, there are two different ways to create a connection object to access the database through a JDBC driver:

The JDBC documentation suggests several options on how to use DataSource classes provided by the JDBC driver:

1. Using JDBC driver's DataSource classes directly without using JNDI. Here is a sample code:

  AbcDataSource ds = new;
  Connection con = ds.getConnection();

2. Using JDBC driver's DataSource classes indirectly through a JNDI directory service. One example is to use Sun's File System Service Provider as shown in the sample code:

  Hashtable env = new Hashtable();
  env.put(Context.PROVIDER_URL, "file:/temp");
  Context ctx = new InitialContext(env);

// Storing a DataSource object
  ClientDataSource dsIn 
    = new org.apache.derby.jdbc.ClientDataSource();
  ctx.bind("DerbyTestDB", dsIn);

// Retrieving a DataSource object
  DataSource dsOut = (DataSource) ctx.lookup("DerbyTestDB");
