THE TECHNIQUE DEVELOPMENT HISTORY OF JSP

By:Kathy Sierra and Bert Bates

Source: Servlet&JSP

The Java Server Pages( JSP) is a kind of according to web of the script

plait distance technique, similar carries the script language of Java in

the server of the Netscape company of server- side JavaScript( SSJS) and

the Active Server Pages(ASP) of the Microsoft. JSP compares the SSJS and

ASP to have better can expand sex, and it is no more exclusive than any

factory or some one particular server of Web. Though the norm of JSP is

to the Sun parlance, the JSP can adapt to include the Apache WebServer,

IIS4.0 on the market at inside of 85% server product.

This chapter will introduce the related knowledge of JSP and Databases,

and JavaBean related contents.

1.1 GENER ALIZE

The JSP(Java Server Pages) is from the company of Sun Microsystems

language engine to carry out the procedure code in the code of HTML.

JSP pages are translated into servlets. So, fundamentally, any task

this underlying equivalence does not mean that servlets and JSP pages are

technology, it is the convenience, productivity, and maintainability of

one or the other. After all, anything you can do on a particular computer

platform in the Java programming language you could also do in assembly

language. But it still matters which you choose.

JSP provides the following benefits over servlets alone:

• It is easier to write and maintain the HTML. Your static code is

presentation layer. On large projects, this division is very important.

Depending on the size of your team and the complexity of your project,

you can enforce a weaker or stronger separation between the static HTML

and the dynamic content.

Now, this discussion is not to say that you should stop using servlets

and use only JSP instead. By no means. Almost all projects will use both.

For some requests in your project, you will use servlets. For others, you

will use JSP. For still others, you will combine them with the MVC

architecture . You want the apGFDGpropriate tool for the job, and servlets,

by themselves, do not complete your toolkit.

The Java Servlet is a technical foundation of JSP, and the large Web

the Applet, the local translation method of now is a lot of, this book

in order not to misconstruction, decide the direct adoption Servlet but

don't do any translation, if reader would like to, can call it as" small

service procedure". The Servlet is similar to traditional CGI, ISAPI,

NSAPI etc. Web procedure development the function of the tool in fact,

Servlet is also a terrace irrelevant, actually, as long as match the norm

of Java Servlet, the Servlet is complete to have nothing to do with terrace

and is to have nothing to do with server of Web. Because the Java Servlet

is internal to provide the service by the line distance, need not start

a progress to the each claimses, and make use of the multi-threading

mechanism can at the same time for several claim service, therefore the

efficiency of Java Servlet is very high.

But the Java Servlet also is not to has no weakness, similar to

traditional CGI, ISAPI, the NSAPI method, the Java Servlet is to make use

A number of years ago, Marty was invited to attend a small 20-person

seat next to Marty was James Gosling, inventor of the Java programming

large software company in Redmond, Washington. During the discussion, the

moderator brought up the subject of Jini, which at that time was a new

Java technology. The moderator asked the manager what he thought of it,

and the manager responded that it was too early to tell, but that it seemed

to be an excellent idea. He went on to say that they would keep an eye

on it, and if it seemed to be catching on, they would follow his company's

did it years earlier. Even ASP (a product from the very software company

of the aforementioned manager) popularized this approach before JSP came

along and decided to jump on the bandwagon. In fact, JSP not only adopted

the general idea, it even used many of the same special tags as ASP did.

The JSP is an establishment at the model of Java servlets on of the

expression layer technique, it makes the plait write the HTML to become

more simple.Be like the SSJS, it also allows you carry the static state

HTML contents and servers the script mix to put together the born dynamic

state exportation. JSP the script language that the Java is the tacit
