Java Development Eclipse FAQ (i) The superclass "Javax.servlet.http.HttpServlet" is not found on the Java Build Path

I've recently started with Eclipse, and it's just beginning with a tutorial step-by-step new Web project, and there's nothing wrong with that.

Today selected a new workspace, built a Web project to find the simplest JSP page error: The superclass "Javax.servlet.http.HttpServlet" is not found on the Java Build Path

Baidu to find the reason, now summed up, although is a simple question, but the novice will certainly meet.

The reason for the error is that the Web project is missing the compile Tomcat runtime related classes, just add the line.

1. Select Project Right-click or build path-configure build Path-libraries-add Libraries

2. In the popup box, select the server runtime-next-apache-tomcatv7.0-finish

3, go back to just the window select order and export-Select the apache-tomcatv7.0 you just added

4. Reopen the page and solve the problem.
