Whenever there is an application to write, breaking it up to small pieces is a great idea. The smallest piece of any application would probably be a data object, or a simple Bean in Java. Java Beans are simple Java classes that have a distinctive look and behavior. Their simplest purpose is to contain data and they accomplish this by having properties. Each property is actually a data-member containing/referencing the actual data and a couple of methods, a getter method and a setter method. Thus, the simplest data-bean describing a person could be expressed as such:
jsp和xml。XML and JSP are two important tools available in producing a web application. This chapter examines the
potential of mixing these two technologies in order to enhance the capabilities of JSP. While this chapter will
cover many things about XML, this chapter will not attempt to teach XML. Instead it focuses on how JSP and
XML can be used together as a highly flexible and powerful tool. In general the usage of XML in these
examples will be kept simple and should cause no problems for users who are starting XML.
Testability is the concern most often voiced by Texas Instruments (TIä )
application specific integrated circuit (ASIC) users. This document is intended
to consolidate TI policies into a coherent approach to designing for testability.
It is not intended as a specification, but as a guide you can use for developing
test strategies when designs are being initiated
