Observe that the name and value of the cookie are displayed in the browser In this example, an expiration date is not explicitly assigned to the cookie via the setMaxAge( ) method of Cookie Therefore, the cookie expires when the browser session ends You can experiment by using setMaxAge( ) and observe that the cookie is then saved to the disk on the client machine

HTTP is a stateless protocol Each request is independent of the previous one However, in some applications, it is necessary to save state information so that information can be collected from several interactions between a browser and a server Sessions provide such a mechanism A session can be created via the getSession( ) method of HttpServletRequest An HttpSession object is returned This object can store a set of bindings that associate names with objects The setAttribute( ), getAttribute( ), getAttributeNames( ), and removeAttribute( ) methods of HttpSession manage these bindings It is important to note that session state is shared among all the servlets that are associated with a particular client The following servlet illustrates how to use session state The getSession( ) method gets the current session A new session is created if one does not already exist The getAttribute( ) method is called to obtain the object that is bound to the name date That object is a Date object that encapsulates the date and time when this page was last accessed (Of course, there is no such binding when the page is first accessed) A Date object encapsulating the current date and time is then created The setAttribute( ) method is called to bind the name date to this object

Financial Applets and Servlets
espite all the large, sophisticated applications, such as word processors, databases, and accounting packages, that dominate much of the computing landscape, there has remained a class of programs that are both popular and small These perform various financial calculations, such as the regular payments on a loan, the future value of an investment, or the remaining balance on a loan None of these calculations are very complicated or require much code, yet they yield information that is quite useful As you know, Java was initially designed to support the creation of small, portable programs Originally, these programs took the form of applets, but a few years later, servlets were added (Recall that applets run on the local machine, inside the browser, and servlets execute on the server) Because of their small size, many of the common financial calculations are right-sized for applets and servlets Furthermore, including a financial applet/servlet in a web page is an amenity that many users will appreciate A user will return again and again to a page that offers the calculation that he or she desires This chapter develops a number of applets that perform the financial calculations shown here:
Regular payments on a loan Remaining balance on a loan Future value of an investment Initial investment needed to attain a desired future value Annuity from an investment Investment necessary for a desired annuity
