Is your Java application running slowly? Can they not withstand the rising traffic? This article describes the development of high-performance, highly resilient JSP pages and the performance optimization of the servlet technology. The idea is to build as fast as possible and adapt to a growing number of users and their requests. In this article, I'm going to take you through the performance tuning technique
Abstract: This article introduces a web-based management information system implementation framework. Using JSP/Servlet technology and MVC design patterns makes the development process more flexible and easy to maintain.
Key words: Management Information System JSP servlet MVC design mode JDBC

In this article, you'll learn about performance tuning techniques that have been practiced and proven, which will greatly improve the performance of your servlet and JSP pages, and hence the performance of Java EE. Parts of these technologies are used in the development phase, such as the design and coding phases. Another part of the technology is related to configuration.

Compared with ASP and PHP, servlet/jsp technology has high execution efficiency because of its multithreading operation. Because servlet/jsp is performed in multithreaded mode by default, multithreading synchronization issues need to be c
Enterprise Server can be transplanted to Apache, Microsoft IIS, or WebStar without any material changes. Almost all mainstream servers support servlets directly or through plug-ins.Save investment.Not only are there many low-cost or even free Web servers available for personal or small-scale websites, but if the existing server does not support Servlet, this feature is often free (or requires a very small investment ).1.2

Typically, in a well-designed web application, servlet and JSP technologies are used synthetically. The servlet controls the flow of business, and the JSP is responsible for the display of the results of the business process. In this case, the redirection

Overview
In this article, Rahul Chaudhary describes the use of the Performance tuning technology (PTT performance-tuning techniques) to enhance the performance of servlets and JSP to improve the performance of your Java EE application. The author assumes that the reader has basic servlets and jsps knowledge.
Is your Java application running slowly? Can they meet enough pressure? Th
Compared with ASP and PHP, ServletJSP has a high execution efficiency due to its multi-threaded operation. Because ServletJSP is executed in multi-thread mode by default, you need to carefully consider the multi-thread synchronization issue when writing code. However, many developers did not notice the problem of multi-thread synchronization when writing the ServletJSP program, which often caused the programming servlet

Relative and absolute paths in JSP and ServletThe absolute path and Relative Path Problems in JSP and Servlet have plagued me for several days. After some efforts, I will share some of my experiences with you.Premise: assume that your HTTP address is http: // 192.168.0.1/your web application is webapp, then your web application URL is http: // 192.168.0.1/webapp/
In Web Server programming, session state management is an important issue that must be considered frequently. This article analyzes the session management mechanism of JSP/Servlet and the problems it faces, and then proposes an improved session management method.

It works on the server. When forward () is used, the Servlet engine transmits the HTTP request from the current Servlet and JSP to another Servlet, JSP or common HTML file, that is, your form is submitted to.
Comparison between servlet and JSP
1. The servlet is loaded by the web server. The web server must contain the JVM that supports servlet. The nature of the servlet is that the JAVA application running on the server side.
2. JSP
We often say that JSP has nine large built-in objects are: request, response, session, out, PageContext, page, exception, application, CONFIG.
We know that the JVM can only recognize Java classes and not recognize JSP code, so how are these objects generated? This will refer to the servlet. A servlet is a server-side p
