How to open jsp file

The steps to open a jsp file require installing a Java development environment, configuring the web server, creating a JSP file and deploying it to the web server, then starting the web server and entering the URL address of the JSP page in the browser to access it. Detailed introduction: 1. Install the Java development environment and ensure that the Java development environment has been installed on the computer. You can download the JDK version suitable for the operating system from the Oracle official website and install it according to the official documentation; 2. Configure the Web server, etc.

This means that you need to make sure that the web server is started and that the JSP files are properly deployed to the server.

To summarize, to open a JSP file, you need to install the Java development environment, configure the Web server, create the JSP file and deploy it to the Web server, then start the Web server and enter the URL address of the JSP page in the browser. access it.
