6、rucial part of every computer programme with regard to its responsibility for interaction with the users. This part of application should be flexible,which means susceptible to any needed changes and without any doubts,

7、user – friendly. Regrettably, process of developing such user interface in the main requires usually a profusion of developer's work and time, making the whole development process involved and onerous.The most apting

8、 technology to this field is JavaServer Faces (JSF). This holistic, component-based solution for longstanding problems facing software developers has a specific goal: to make web development faster and easier by masking

9、a lot of complexities hidden behind this kind of transport data between relational database and Java, .Net or Ruby application. Contrary to popular Hibernate library, iBatis does not directly tie classes to tables or fie

10、lds to columns, but instead, it couples objects with results of stored procedures or SQL statements using simple XML descriptor letting the developer to reach only for required data. The iBatis framework can map nearly a

11、ny database to any object model and is very tolerant of legacy designs, or even bad designs.Simplicity is the main advantage of the iBatis over other frameworks.The Hotel Reservation System was primarily built upon JSF t

17、IONIn a nutshell, JSF – Spring integration makes Spring managed beans visible as variables to JSF, just as if the Spring beans are configured as JSF managed beans.Before diving into the integration specifics of JavaServe
