index.jsp Error The Superclass "Javax.servlet.http.HttpServlet" is not found on the Java Build path solution

1.index.jsp Error The Superclass "Javax.servlet.http.HttpServlet" is not found on the Java Build path solution

The main cause of the Javaweb project class is that there is no Web container runtime related class being added:

First:

Right-click the project name->propertise->java build path->libraries->add libraries->server runtime-> Choose your Tomcat server- >finish, after this, the Java file is wrong.

Second:

Switch to Orader and Export in the Java Build path interface, select the jar package that needs to be used, I am all hooked up to the JSP newspaper error is gone.
