java - javax.servlet.* cannot be resolved to a type

Question

I am running ubuntu 14.04 and eclipse Kepler (with java ee modules preloaded) , I am developing Dynamic Web App for first time, it always says javax.servlet.xyz cannot be resolved to a type please help I am including a screen snapshot for my error page!

Answer 1

Only two things are required in Eclipse for this:

One

In Eclipse, Window -> Preferences -> Server -> Runtime Environment
Specify your Web Server or Application Server path, by adding a "New Server Runtime Environment".

Update

Initially, there are only few Server Runtime Environments available with Eclipse like:

1. Apache
2. Basic
3. ObjectWeb

On an additional note, you can add more Server Adapters using the link Download additional server adapters in Server Runtime Environments dialog screen.

Two

In Project Properties (Right Click on Project -> Properties), in Java Build Path, add Library "Server Runtime".
On adding Server Runtime to Project Library will add servlet-api.jar and jsp-api.jar jars to project dependencies.
