Answer 1

Do you also have httpcore jar? (version 4.3 as well) I've found that class there.

Answer 2

Maybe you forgot to include/download HttpCore

Answer 3

The org.apache.http.config.Lookup class is not in httpclient-4.3.1.jar. It is in httpcore-4.3.jar.

If you are not using Maven, to understand the httpclient dependencies, see http://hc.apache.org/httpcomponents-client-4.3.x/httpclient/dependencies.html
