New to Java

I am trying to set up a test server for my University project.

I am using Tomcat as this is what my University uses on Campus.

I have set it up ok, I am trying to run a test servet.

When I try to compile the java program using an IDE, it does not recognise the following imported

import javax.servlet.*;
import javax.servlet.http.*;

Do these classes exist as I could not find them on the API documentation?

Can anyone help a frustrated student?

Thanks
