return dataSource;

public String getFirstNameById(Long id) {
List<String> result = sfFirstNameById.execute(id);
return result.get(0);
}
}
In Listing 8-53, upon data source injection, an instance of SfFirstNameById is constructed. Then in
the getFirstNameById() method, its execute() method was called, passing in the contact ID. The method
will return a list of Strings, and we need only the first one, because there should be only one record
returned in the resultset.
Listing 8-54 shows the Spring configuration file for connecting to MySQL (app-context-sf.xml).

In Listing 8-54, the file datasource-dbcp.xml is imported, which holds the datasource configuration
to the MySQL database. To run the program, the dependency on commons-dbcp should be added to the
project, as shown in Table 8-5.
