up large, the Web that can upgrade applies the procedure. The expression logic write in the
script environment was lock in the page, only passing to shear to slice and glue to stick then
can drive heavy use. Express the logic to usually mix together with business and the data
logics, when this makes be the procedure member to try to change an external appearance that
applies the procedure but do not want to break with its llied business logic, apply the
procedure of maintenance be like to walk the similar difficulty on the eggshell. In fact in the
business enterprise, heavy use the application of the module already through very mature, no
one would like to rewrite those logics for their applied procedure.HTML and sketch the
designer handed over to the implement work of their design the Web plait the one who write,
make they have to double work- Usually is the handicraft plait to write, because have no fit
tool and can carry the script and the HTML contents knot to the server to put together. Chien
but speech, apply the complexity of the procedure along with the Web to promote
continuously, the development method that take page as the center limits sex to become to get
up obviously.
At the same time, the people always at look for the better method of build up the
Web application procedure, the module spreads in customer's machine/ server the realm.
JavaBeans and ActiveX were published the company to expand to apply the procedure
developer for Java and Windows to use to come to develop the complicated procedure
quickly by" the fast application procedure development"( RAD) tool. These techniques
make the expert in the some realm be able to write the module for the perpendicular
application plait in the skill area, but the developer can go fetch the usage directly but need
not control the expertise of this realm.
Be a kind of take module as the central development terrace, the JSP appeared. It with
the JavaBeans and Enterprise JavaBeans( EJB) module includes the model of the business and
the data logic for foundation, provide a great deal of label and a script terraces to use to come
to show in the HTML page from the contents of JavaBeans creation or send a present in
return. Because of the property that regards the module as the center of the JSP, it can drive
Java and not the developer of Java uses equally. Not the developer of Java can pass the JSP
label( Tags) to use the JavaBeans that the deluxe developer of Java establish. The developer of
Java not only can establish and use the JavaBeans, but also can use the language of Java to
come to control more accurately in the JSP page according to the expression logic of the first
floor JavaBeans.
See now how JSP is handle claim of HTTP. In basic claim model, a claim directly was
send to JSP page in. The code of JSP controls to carry on hour of the logic processing and
