Can you point me to a working sample project that uses a Derby... erm... javaDB
database and successfully creates and uses a connection using the new Java EE 5
@Resource annotation (i.e., resource injection).

I have a simple JSP-based project that uses JNDI lookup, and I want to simplify
my code using resource injection.

Specifically I here is the old JNDI code I have working 
/////////////
            // Retrieve the DataSource from JNDI
            Context ctx = new InitialContext();
            if ( ctx == null ) {
                throw new RuntimeException("JNDI Context could not be found.");
            }
            ds = (DataSource)ctx.lookup("java:comp/env/jdbc/leagueDB");
            if ( ds == null ) {
                throw new RuntimeException("DataSource could not be found.");
            }
            
            
            // Get a database connection
            connection = ds.getConnection();
////////

replace the above with something like this:
////////

    private @Resource(name="jdbc/leagueDB") DataSource ds;
    ...
    ...
            // Get a database connection
            connection = ds.getConnection();
////////

But the call to getConnection() fails.

Please point me to a working sample project, or some COMPLETE instructions.
