When Eclipse is imported to a Java Web project, The following error occurs: the superclass "javax. servlet. http. HttpServlet" was not found on The Java Build Path, httpservlet

The JSP page written in the Java Web project must be parsed into HTML by the Web Container before it can be displayed to the front-end browser. parsing JSP requires the Web container.
The "red" error message appears at the top of The JSP page: the superclass "javax. servlet. http. HttpServlet" was not found on The Java Build Path.

 

Javax. servlet. http. HttpServlet is a class in the Web Container Tomcat package. importing the required jar package into the project can solve this problem.

The specific solution is as follows:

Right-click the web Project and choose Build Path> Java Build Path> Libraries> Add Libray> Server Runtime> Tomcat Server.
