Question

I wanted to use javax.servlet.http.HttpSessionListener interface in my project. The project can’t find a proper jar.

Which jar do I need to include in the project? Which package?

Edit

Seems like a different problem, new question here.

Answer 1

I think servlet-api.jar will do it.

and if project still can’t find a proper jar, then you must try to add it again [as you have said that you are using eclispe so you can add it using properties-> build path -> configure build path -> add external jars].
