ServletException, HttpServletResponse and HttpServletRequest cannot be resolved to a type [duplicate]

Question

I got an error while creating a servlet in eclipse like

Multiple markers at this line

• ServletException cannot be resolved to a type
• HttpServletResponse cannot be resolved to a type
• HttpServletRequest cannot be resolved to a type

Answer 1

You can do the folllwoing: import the jar file inside you class:

import javax.servlet.http.HttpServletResponse

add the Apache Tomcat library as follow:

Project > Properties > Java Build Path > Libraries > Add library from library tab > Choose server runtime > Next > choose Apache Tomcat v 6.0 > Finish > Ok

Also First of all, make sure that Servlet jar is included in your class path in eclipse as PermGenError said.

I think this will solve your error

Answer 2

Two possible issues could be

• you either forgot to include Servlet jar in your classpath
• you forgot to import it in your Servlet class

To include Servlet jar in your class path in eclipse, Download the latest Servlet Jar and configure using buildpath option. look at this Link for more info.

If you have included the jar make sure that your import is declared.

import javax.servlet.http.HttpServletResponse
