jsp online shopping system development background

The system mainly realizes the function of members purchasing goods and administrators There are two basic functions such as desk management.

Online Shopping System Paper Abstract This article develops and designs the interactive e-store system of "maomao e-shopping street" with today's popular ASP technology. Adopt the structured life cycle method, top-down, layer-by-layer decomposition, modular system structure design.

Less investment, fast return.According to a survey of small and medium-sized enterprises in China, the average cost of setting up a sales company online is at least 50,000 yuan, while the cost of opening a store online is very small. Generally speaking, the investment in opening an online store is very small. You don't need to apply for a business license, rent a store or buy products.

The system is independent and secure, and the online shopping system is developed. Because it is independently developed and operated by the enterprise, its system database is also independent.

Improve user experience. The development of e-commerce shopping system means that it can effectively improve user experience.E-commerce shopping systems usually have online customer service systems.

What are the advantages of JSP

1. Advantages of Jsp: one-time writing, running everywhere. Except for the system, the code does not need to be changed. Multi-platform support of the system. Basically, it can be developed in any environment on all platforms, system deployment in any environment, and expansion in any environment. Compared with the limitations of ASP, the advantages of JSP are obvious.

2. Advantages JSP code is cross-platform, that is, it is written once and runs everywhere. JSP components can be reused across platforms, and enterprise JavaBeans components can access traditional databases and work on Solaris, Linux, UNIX and Windows platforms in distributed system mode.Support a variety of web page formats.

3. Advantages of JSP: · The update of the user interface is actually carried out by the Web Server, so it gives people the feeling that the update is very fast. · All applications are server-based, so they can always maintain the latest version. · The interface of the client is not very cumbersome, and it is easy to deploy, maintain and modify for various applications.

Linux system Jsp environment: Apache, Tomcat configuration

Go to java.sun.com to download Li first JDK on nux, I downloaded 0.

Yes, but when processing static files such as jpg, gif and html, tomcat is not as efficient as APACHE. If it is not a website with a large number of visits. One TOMCAT is enough.

To install TOMCAT, you only need to decompress TOMCAT (in general, Linux comes with a tool to decompress .gz, .tar format files., double-click), stored in the custom directory, the author's custom directory is: /usr/tomcat, and then you can set the TOMCAT_HOME environment variable (already set above).

jsp online examination system

Do you want to do an exam discipline question about attendance? For example, you are not allowed to answer questions 15 minutes before the beginning of the exam, and you are not allowed to hand in papers 30 minutes before the end? You can try to achieve this with Quartz.

The jsp page can control the time by making a countdown prompt.

You can get a hyperlink. When querying the database, only one record is displayed on each page. When you click the hyperlink "previous question" and "next question", you can read the previous and next record.You need to find out how many records there are in total and set how many records are displayed on each page.
