How to Solve Servlet Errors in Eclipse?

Servlet Errors in Eclipse

For new users, it’s common to encounter following errors while developing servlet in Eclipse (I am using eclipse-jee-indigo-SR2-win32) or without it:

HttpServlet cannot be resolved to a type
HttpServletRequest cannot be resolved to a type
HttpServletResponse cannot be resolved to a type
ServletException cannot be resolved to a type
The import javax.servlet cannot be resolved
WebServlet cannot be resolved to a type

The problem is “servlet-api.jar” is not on classpath.

How to add servlet-api.jar in classpath from Eclipse?

Right Click on the Web Project and Click on Properties

Select Java Build Path

Click on the Library Tab

Click on “Add External Jar” -> Locate servlet-api.jar from your local system (It’s available in Tomcat Distribution directory.)

Click OK and all errors will be resolved.

Done!!!
