The js|web| program JSP (JavaServer Pages) technology is a further abstraction of the servlet, developed by the JCP (Java Community Process), an open, freely accessible specification for generating dynamic content, It is also an important part of the Java 2 Enterprise Edition specification. Many business application servers such as Bea WebLogic, IBM WebSphere, Live JRun, and Orion support JSP technology.
JSP learning notes (1): JSP basics and jsp learning notes BasicsI. Principles1. HttpServlet is first compiled from the source code into a class file and then deployed to the server. Compile and deploy the SDK. 2. JSP first deploys the source code and then compiles it into the class file, and then compiles it.
Today in doing homework encountered a problem, before we write JSP code is placed in the webcontext directory, not placed under its subdirectory under the wed-inf directory, all causes the browser can directly access the JSP, So there is a great security problem, after understanding, the correct wording is to put the JSP file under the Wed-inf directory, and then
1. Simple grammarExpression Language (EL) is added to JSP 2.0 specification. The purpose of EL is to produce scriptless JSP pages. The syntax of EL in a JSPs is as follows:${EXPR}Here expr Specifies the expression itself.(1) The two commonly used operators in a JSP El are: "." and "[]".The most common operators in

A. JSPprinciple: JSP is actually a servlet.Servlet responsible for business logic processing, JSP is only responsible for display. In development, there cannot be a single line of Java code in the JSPTwo JSP Syntax1. jsp template elements: HTML tags and text in JSP2. Script: Write Java code, 3. expression: For output
I. JSP running principle when each JSP page is accessed for the first time, the WEB Container will send the request to the JSP Engine (a Java program) for processing. The JSP Engine first translates JSP into a _ jspServlet (essentially a servlet) and calls it according to th
for processing.(2) Each JSP page is accessed for the first time, the JSP engine translates it into a servlet source program, and then compiles the servlet source program into a servlet class file. The Web container (servlet engine) is then loaded and interpreted in the same way as a normal servlet program to execute the servlet program translated by the JSP page
, the following error message appears:http://localhost:8080/MyApp/jsp/jsp/register.jspThe above problem is caused by the different URL of the calling page and the page being called.This type of error also often occurs when a "forward" (forward) operation is performed between 2 pages.Because forward is done in the background, it is transparent to the client. (that is, the URL does not change, and the data co
JSP compiler directives are information that notifies the JSP engine that it does not generate output directly. There are three common compiler directives:Page directiveThis directive is a descriptive instruction for the entire JSP page. The syntax format is as follows:The% @page[language= "Java"][extends= "Package.cla

You can use tools that are usually handy and write HTML statements in the usual way. The dynamic parts are then embedded with special tags, which often start with "
