Enhancements to the Application

You can make the application even more useful by making the following additions:

• Section 10.1, "Adding Security Features"

• Section 10.2, "Publishing the Application as a Web Service"

10.1 Adding Security Features

As it stands, any user can enter an employee ID and make changes to that employee's benefits. This is probably not what you want. You can add a login page that prompts the user to enter a login ID and password. The application can then verify the login against a directory server.

10.2 Publishing the Application as a Web Service

Web services enable diverse clients, independent of language or operating system, to invoke methods on your application. In the Employee Benefit application, you can expose business logic methods by exposing the EmployeeManager session bean. Typically, you would expose methods declared in the session bean's remote interface. Clients can then process the return values as they see fit.
