Answer 1

Sure it is.
Try something like this (and maybe get a book on JDBC):
String name;
try {
     InitialContext ic = new InitialContext();
     DataSource ds = (DataSource) ic.lookup(Constants.MY_DATASOURCE);
     Connection connection = ds.getConnection();
     String sql = "SELECT * FROM TABLE";
     PreparedStatement statement = connection.prepareStatement(sql);
     ResultSet rs = statement.executeQuery();
     while (rs.next()) {
          name = rs.getString("NAME");
     if (rs != null)
          rs.close();
     if (statement != null)
          statement.close();
     if (connection != null)
          connection.close();
catch (NamingException e) {
     // Can't get JDBC datasource
     // ... do something with this exception
catch (SQLException e) {
     // SQL exception from getter
     // .... do seomthing with this one too
}
