/**
* EmployeeListAction
* <p>
* This class provides form functions for searching and displaying a list of employees. This implementation shows two optional
* approaches for this. 1. Use a ReaderListActionSupport object to directly display database query results in the JSP.<br>
* This is most efficient, however it lacks some flexibility.<br>
* 2. Use a BeanListActionSupport object to obtain a list of JavaBean objects from the query.<br>
* From the JSP the data of the list will be accessed though their getter and setters.<br>
* While this is not a efficent as the Reader approach, it is more flexible since post processing of the query result is
* possbile.
* </p>
