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

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, is all certainly rougher introduction among them basic contents, say perhaps

to is a Guide only, if the reader needs the more detailed information, pleasing the book of

consult the homologous JSP.

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

companies the participate to the build up the together of the a kind the of dynamic the state

web the page technique standard, the it have the it in the construction the of the dynamic state

the web page the strong but the do not the especially of the function. JSP and the technique of

ASP of the Microsoft is very alike. Both all provide the ability that mixes with a certain

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 ordinary HTML: no

extra backslashes, no double quotes, and no lurking Java syntax.

You can use standard Web-site development tools. Even HTML tools that know nothing

about JSP can be used because they simply ignore the JSP tags.

You can divide up your development team. The Java programmers can work on the

dynamic code. The Web developers can concentrate on the presentation layer. On large

projects, this division is very important. Depending on the size of your team and the

themselves, do not complete your toolkit.

The technique of JSP of the company of Sun, making the page of Web develop the

personnel can use the HTML perhaps marking of XML to design to turn the end page with

format. Use the perhaps small script future life of marking of JSP becomes the dynamic state

on the page contents.( the contents changes according to the claim of)

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

development of the procedure to need the Java Servlet to match with with the JSP and then

can complete, this name of Servlet comes from 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

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 of to output the HTML language sentence to

carry out the dynamic state web page of, if develop the whole website with the Java Servlet,

the integration process of the dynamic state part and the static state page is an evil-foreboding

dream simply. For solving this kind of weakness of the Java Servlet, the SUN released the

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 usual "embrace and extend" strategy. At this point, Gosling lightheartedly

interjected "You mean disgrace and distend."

Now, the grievance that Gosling was airing was that he felt that this company would take

technology from other companies and suborn it for their own purposes. But guess what? The

shoe is on the other foot here. The Java community did not invent the idea of designing pages

as a mixture of static HTML and dynamic code marked with special tags. For example, Cold

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