javaweb: Error message the superclass "Javax.servlet.http.HttpServlet" is not found on the Java Build Path
long time no JSP was written, a Javaweb project was built today, and Web container tomcat was configured in Eclipse. Originally happy to create a new JSP page, add a simple Java class. However, there is a "red" error message at the top of the JSP page: the superclass "Javax.servlet.http.HttpServlet" is not found on the Java Build Path. The original Javaweb project class was not added to the Tomcat runtime related classes caused. here are the specific workarounds:1. Right-click Web Project-"Properties or Build path-" Java build path->libraries-> Add libray...->server Runtime-"Tomcat Server2. Switch to Orader and Export in the Java Build path interface and select Tomcat. Note:
When you do this, you need to set up an Apache server if you open the Server runtime blank. Set the method to: Window->preferences->server->runtime environment, add-on, select the Apache version and click Next. Then fill in the installation (unpacked) address of your Apache server software.
